*Lab data recorded before the power update
**Important note: Comparing individual weights is pointless. What really matters is the total system weight, including the battery and all mounting components within the frame. Even more crucial is the weight distribution on the bike, which affects handling far more than the total weight alone. A removable battery always adds extra weight.

Our test field in detail – how we categorised the motors in our e-bike motor group test

TQ HPR60
TQ present the HPR60 as the benchmark for natural, harmonious support in the light e-bike segment. It’s ultra-compact, exceptionally quiet and almost invisible within the frame. This motor is aimed at riders who value integration and subtlety over raw power on paper.

FAZUA Ride 60
FAZUA position the Ride 60 as a sleek, seamlessly integrated drive system for slim, stylish eMTBs. With its discreet looks, natural ride feel and smooth support, it’s designed to make the bike feel more like a traditional, motorless MTB – just with a constant artificial tailwind.

maxon AIR S
At first glance, the maxon AIR S looks like a typical light-assistance motor – but it’s built to deliver full-power performance. Compact, lightweight and powerful despite its relatively small battery, maxon are banking on high-tech efficiency rather than brute force.

Shimano EP801
With the EP801, Shimano enter this group test with one of the most seasoned motors. It’s known for finely tuned power delivery and dependable climbing performance. Features like Auto Shift and Di2 shifting integration are designed to offer maximum comfort and reliability on the trail.

Pinion MGU E1.12
Pinion’s MGU is the most distinctive concept in the entire test field: a motor, gearbox, belt drive and optional automatic shifting, all housed in a single unit. While it’s visually bulky and not the quietest out there, it’s virtually maintenance-free and packed with unique features like shifting while stationary – a truly different approach.

S-Works 3.1
Specialized present their 3.1 motor as part of a fully integrated ecosystem: motor, battery, remote, app and bike design all come from a single source. It’s backed by a huge range of features and finely customisable support profiles. The hardware is tightly aligned with Specialized’s own portfolio – from range extender to app, everything feels purpose-built and seamlessly connected.

Bosch Performance Line SX
The SX is Bosch’s lightweight motor for sporty, active riders who prefer higher pedalling cadences and a more subtle, less intrusive ride feel. While it’s not quite as discreetly integrated into the frame as the most compact light drive systems, it scores points thanks to the full Bosch Smart System backing it up.

Bosch Performance Line CX-R
The CX-R is Bosch’s race-bred drive unit: ultra-responsive, uncompromising and built with a clear focus on competition and performance. Combined with the Bosch ecosystem, it offers manufacturers a wide choice of batteries, displays, remotes and global service coverage – though the motor itself is unmistakably geared towards racing and speed.

Bosch Performance Line CX
The CX is the all-rounder classic and probably the most widely used full-power motor in eMTBs. It may not break records in any one category, but it’s a mature, well-rounded system with solid hardware and an extensive network of partners.

Avinox M1
The Avinox M1 enters the race as a high-tech powerhouse from China, offering the highest peak output and torque in the entire test field. It comes wrapped in a tightly integrated ecosystem featuring a touch display, app and fast-charging functionality. Avinox pitch it as a smart, high-performance system that brings electronic and software expertise from other industries into the eMTB world.

MAHLE M40
The M40 marks MAHLE’s move into the full-power mid-drive segment. Compact, punchy and finely tuned for sensitive support, it aims to change MAHLE’s image from a hub motor specialist to a serious player offering a lightweight, modern package for full-fledged eMTBs.

Inside our Motor Madness: the test crew – measuring tools, sore legs and strong opinions

Our test team isn’t some anonymous data vacuum – we’re a tight-knit crew with strong personalities, clear opinions and very different perspectives. Different expectations, body types, riding styles and preferences. From the watt wizard to the weight weenie and the weekend warrior who always runs the battery down to 0%, we’ve got the full spectrum covered – everything you need to not just test motors, but truly understand them.

We documented, debated, cursed and laughed. And we rode until the battery warning flashed red. Between vertical range tests, noise measurements and “just-for-fun” laps, we didn’t just break each system down technically – we also rated them emotionally. Because a motor is more than just numbers – and our team is more than just an Excel sheet.

Bene: „Alright, straight up – how does this thing feel in Turbo mode?“

Lars: „If the mode’s called Turbo, I expect it to hit hard.“

Peter: „It did. In my back.“

Ingo: „Efficiency: subterranean. Noise: subway at full throttle.“

Erik: „Felt smooth to me – but I don’t weigh 90 kilos with gear.“

Jan: „Yeah, you also like goulash out of a can. I ran the battery down to 2%. After that it was just training.“

Robin: „Let’s talk about the overall package!“

Ingo: „Overall package is 3.08 kg. Just the motor. No mount.“

Robin: „…I’m done.“

How we tested: trails, lab sessions, vertical range & more

We’ve never put this much effort into a motor group test – and no other magazine has either. But it’s worth it. Not to drown you in data, but to give you the context that really matters. To explain what’s behind the numbers – and to tell you what truly counts.

On the trail – putting motors through their paces off-road

The most important part of our testing took place where e-mountainbikes belong: out on the trails. Technical specs and polished performance charts only tell half the story – what really matters is how a motor system performs in the real world.

To cover the full range of riding scenarios, we designed a test loop with maximum variety: steep climbs, ledges and steps, slippery rock slabs, rough descents and fast sections of tarmac. On technically demanding uphills, we deliberately pushed each motor to and beyond its limits. This is where things like fine-tuning, modulation and responsiveness come into play – but it’s also where raw torque and peak power truly show their worth. Our goal? To replicate every real-world scenario where an eMTB motor has to perform, from daily rides to hardcore use.

In the lab – measured performance at the DEKRA HQ in Stuttgart-Vaihingen

To translate our trail impressions into measurable results, we tested all drive systems at the DEKRA lab in Stuttgart. We focused on several key metrics:

• mechanical power output in relation to rider input
• maximum support output
• sustained power delivery at maximum output over a 30-minute period
• mechanical power at gradients of 7% and 15%
• mechanical power on flat terrain

This allowed us to compare and evaluate each system objectively – and independently of rider impressions or manufacturer claims.

Idle resistance – how freely a motor pedals without assistance

We also measured the idle torque – that is, the amount of force required to turn the cranks when the motor isn’t providing any support. This value reflects all internal friction and losses within the system: motor components, gearbox, seals, bearings and gears.

Why does this matter?

• Efficiency: High idle resistance means more energy is lost within the system and not translated into forward motion. In a way, the motor is fighting against its own internal friction.
• Light eMTBs: On lightweight bikes like the Yeti MTe (TQ HPR), Santa Cruz Heckler (FAZUA Ride60), Pivot Shuttle SL/AM (Bosch SX) and the Instinctiv (maxon AIR S), low idle torque is essential for a natural ride feel above the 25 km/h threshold. If you’re descending or riding faster on the flats and want to keep pedalling actively, you’ll notice immediately whether the bike gains speed smoothly or feels like you’re pedalling into a wall.

Noise measurement – how loud are these motors, really?

To measure noise levels as precisely as possible, we rode across a freshly mown field wearing a microphone clipped to the collar – minimising ambient sounds.

Testing conditions:

• Always in the highest support mode
• Identical gear selection across all bikes
• Flat terrain up to 25 km/h
• A gradient using three different gears to capture sound at varying cadences

The audio data was then analysed using specialised software to ensure an objective comparison of motor noise – not just a gut feeling.

Vertical range – how far and how high can these drive systems really go?

Just like in our big 2025 e-mountainbike group test, we fully drained every motor system in real-world riding conditions. But it’s not just about how far you can go – we focused on vertical range, meaning how many metres of elevation you can realistically gain on a full charge.

This tells us a lot about:

• Sustained power output
• System efficiency
• How motors behave at a low state of charge (SOC) – in other words, when the battery is almost empty

Actual battery capacity vs manufacturer claims

With three motor systems, we went one step further and hardwired the connection between the battery and the motor. This allowed us to:

• Measure the usable capacity of the battery with great precision – the energy actually delivered until the battery was fully empty
• Compare manufacturer percentage readouts with the real energy output
• See how much reserve capacity the system holds back

This gave us deeper insight into how honest the battery percentage displays are – and whether the energy management strategy of each system is conservative or aggressive.

Test conditions for the vertical range rides

To ensure fair and comparable results, we carried out all vertical range tests under identical conditions:

• Route length: 2.47 km
• Average gradient: 8.5%
• Elevation gain per climb: 212 m
• Rider power input: 150 W
• Rider weight: 72 kg
• Cadence: 75 rpm
• Standardised tires with tire pressure front/rear: 1.5 / 1.8 bar

This approach gave us consistent, reliable and repeatable data, allowing us to accurately assess manufacturer claims and compare the drive systems on a level playing field.

The hype is real – but it only tells half the story

Ever since its launch, the Avinox M1 (formerly DJI Avinox) motor has been causing a stir – and the hype? Bigger than ever. But why exactly? Is it the headline power figures? The massive torque? Or are there other factors at play? And can established top dogs like Bosch hold their ground against this rising Chinese heavyweight?

Much of the current mindset in the motor market is, without doubt, a reaction to Avinox’s success. Some players feel cornered, others fear they’re no longer competitive. But are they really? Our latest group test shows there are plenty of other new and seriously exciting products out there – systems that could be the perfect fit for many riders. But they’re being drowned out by the hype, and that’s risky. Because if the industry puts all its eggs in one basket for too long, it could end up far too dependent – if it isn’t already.

Here’s another fact: while many manufacturers now use Avinox’s impressive power figures as a convenient excuse for poor sales, the industry as a whole seems to be getting lost in a performance arms race. More power, then even more power. Some manufacturers are even adding warnings about increased wear and higher energy consumption. But here’s the real question: is that actually what riders want?

We’ve analysed data from over 15,000 readers – and we’ll tell you later: the reality is very different from what many bike brands believe.

Are we too dumb for complex answers – or just too bad at simplifying them properly?

Let’s be clear: the Avinox M1 is an absolutely fantastic motor. But not because of its peak stats – most riders rarely tap into those anyway. Its real strengths lie elsewhere, in areas that are arguably far more important. Yet these are exactly the qualities that are often lost in translation – ignored by most manufacturers, glossed over by the media, and overlooked by retailers.

In recent years, range and battery capacity were all the rage. Then it was all about torque. Now, raw wattage is the latest obsession. And let’s be honest – we’ve all fallen into the same trap: another round of pointless comparison battles. Right now, 120 Nm is basically the 20 centimetres of the bike world. Some in the trade don’t even mind – because high power numbers make for easy sales to customers who haven’t had the chance to dig deeper.

Many bike brands are falling into the same trap. They talk more about the motor, its output, battery size and total weight than about their own brand identity or what makes their bike ride well. In doing so, they reduce themselves to little more than component carriers. And then they act surprised when customers ask for a Bosch or Avinox bike – instead of their bike brand. After that, price becomes the deciding factor. And yes, the media are partly to blame, too. Most influencers and outlets throw peak values into every headline and turn them into instant hype. The message we’re all sending? This is what matters most.

The result: Retailers and ill-informed customers often fixate on these simple numbers, using them as their default buying and selling arguments. Worst-case scenario? Brands start designing their products purely to perform well in pseudo-data-driven comparison tests – even if it’s at the expense of actual ride quality. So be careful!

And yes, we know exactly that we’re not perfect either! But we’re doing our best to offer a more balanced view. And acknowledging the problem is the first step toward fixing it. It’s easy to be dazzled by big numbers and flashy performance claims – only to realise later it’s not what you actually wanted. In a world full of superlatives, the real story gets buried. Nuance gets lost, and suddenly everyone’s just talking about the motor’s weight, peak output and torque. Which is great for the ego and pub chats – but out on the trail, it’s other things that matter! And our group test proves exactly that.

What do riders actually want?

“Customers just want more power!” – this phrase is currently thrown around a lot in the industry when it comes to increasingly powerful motors. But the responses from 15,000 participants in our E-MOUNTAINBIKE reader survey show: it’s a convenient myth. The majority aren’t looking for watt monsters, but for motors with character – quiet, efficient, reliable. Reliability (GSA 57.7% / INT 64.3%) remains the most important factor, closely followed by a natural ride feel (GSA 46.4% / INT 49.6%). Only then comes torque (INT 45.5% / GSA 35.4%).

By the way, even fans of the new Avinox drive system – which dominates in terms of performance – confirm this trend: they love the power, sure, but only when it comes with feeling. Their top priority is high torque, no surprise there. But right behind that come ride feel, low noise levels and efficiency – the things that make all that power manageable. There’s no sign of a blind obsession with output.

Yes, the demand for power is real – but never in isolation. Riders expect new motors to be quieter, more efficient and more intuitive at the same time. So the industry can’t keep hiding behind the excuse that “customers just want power.”

There have already been plenty of high-performance motors before Avinox – but they failed to impress when it came to ride quality, integration or the wider ecosystem. The scene is looking for brains over brawn, for fine-tuning instead of brute force. Quiet, harmonious and reliable systems are the ones that win riders’ hearts.

We need to talk about new superlatives

What does more power actually give you? No one buys a Ferrari just because it has 3 horsepower more than a tuned Golf GTI. You buy it because it makes you feel something – the emotion, the ride experience, the character. And the promise of the brand. So let’s stop talking about wattage. And torque figures, too. Buying a bike based solely on the motor it relies on makes no sense. Unless that motor has a track record of being unreliable – because no one wants unnecessary problems. Just look at what happened with ZF, or with most FAZUA models before the Munich-based team seriously stepped up their quality control.

So, what kind of new superlatives do we actually need?

• “Not the highest power, but usable power.”
• “Not maximum torque, but precise control.”
• “Not motor size, but system integration.”
• “Not motor weight, but weight distribution and overall bike handling.”
  • What’s the point of shaving 200 g off the motor if the battery weighs far more and, in the end, the handling of the complete bike depends much more on weight distribution than on the total weight itself?
  • Unless, of course, you’re just looking to play Top Trumps with e-bikes.

In the end, it’s all about the complete package – the right balance between all the individual factors. Here are a few examples:

For Cesar Rojo from UNNO Bikes, it wasn’t about the Avinox motor offering the highest possible torque or power. What mattered more was how seamlessly the system could be integrated into the frame platform, and what kind of design it allowed them to create – and, just as importantly, the surrounding ecosystem and above all, the rideability.

Light eMTB motors like TQ and FAZUA have always stood out for their discreet integration – and now maxon are taking it a step further with the AIR S. Despite its compact size, typical of light-assistance drive units, it delivers performance that can go head-to-head with a Bosch CX.

An ecosystem like the ones we see from Specialized and Avinox – from apps and control units to integrated displays – massively improves the overall ride experience and boosts system usability.

In the end, designing a motor is always about striking the right balance: between power and noise, efficiency, range and peak output, as well as integration and extra features. Think ABS, fast charging, digital immobilisers, built-in navigation, GPS tracking and lighting.

Connectivity features like live data overlays between a DJI Osmo Action Cam and the Avinox system can be a cool bonus. Functions such as MAHLE’s Hill Brake or Bosch’s Extended Boost can boost safety or push limits on technical climbs.

We see many of these extra features as nice add-ons. However, they’re rarely the deciding factor when buying a bike, but for certain riders, they can offer real benefits – while others couldn’t care less.

Another key point is range. When we talk about performance, peak figures are tempting. But what really matters is what a motor can deliver in sustained, everyday use – and what riders actually want to use. Because you can’t cheat physics: more power always means higher energy consumption. No motor manufacturer can work magic.

Who are you – a brand or just a parts carrier? The biggest risks bike and motor manufacturers are facing right now

As already mentioned, many brands are currently in danger of reducing themselves to little more than parts carriers. Caught up in the cycle of hype, they spec their bikes with whatever product is currently trending and end up marketing the components more heavily than their own brand identity. We recently came across a marketing video where the product manager proudly referred to the “heart” of their bike – the Bosch CX motor – before rattling off all the spec sheet details. Seriously? How interchangeable do you want your bikes to be? The heart of your bike should be its ride quality, your service, the suspension kinematics or whatever makes it unique. Because a great bike isn’t built on a motor’s spec sheet – it’s built on how well that motor is integrated into the bigger picture. Put another way: just because a bike has a good motor doesn’t mean it’s a good bike. And every motor is only as good as the bike it’s built into.

Right now, though, many manufacturers are handing over too much control to motor suppliers – from the ride feel to the user interface and even how the product is differentiated. Yet there are countless ways brands could stand out and take back ownership of their identity.

Some brands are already showing how it’s done better: Specialized, for example, control their entire ecosystem – from the drive unit to the remote, software and app – delivering a ride experience that’s uniquely theirs. Giant are also taking an independent route, playing an active role in the development of their motor systems. And Orbea have taken centre stage with their detuned RS motors and the new HMI RS system, clearly putting the bike itself in the spotlight. They’re making deliberate decisions about the remote, user interface and ride characteristics – instead of blindly handing that over to the motor supplier. The same goes for Rotwild, who have added their own removable battery to the Avinox motor system, creating clear product differentiation. Sure, that also means accepting a few compromises – but it’s a conscious choice.

But forging your own identity doesn’t have to start with a complete system overhaul. One of the simplest ways to stand out? Software. Support levels, power delivery, responsiveness – because all of these parameters can be individually tuned. Or in a single word, CHARACTER. Yet many brands still rely on the default settings provided by their motor suppliers. That’s wasted potential.

That’s why the message is clear: if a brand wants to stay relevant, it needs to be more than just a showcase platform for premium components. Otherwise, no one will ask about the bike anymore – only about the motor.

Power regulation – time for clarity, not panic

There’s still a lot of uncertainty and debate across the industry. As of now – 28th of November 2025 – it remains unclear if or what kind of regulations are coming. Regardless of political decisions, we as a magazine have a clear position. The arguments are complex, and yes, fear is currently doing much of the talking – and we’ll admit, we contributed to that at the start of the year. But the truth is, we’re debating the wrong limits. After countless discussions, including our recent Think Tank in Brixen, one thing has become clear: as an e-bike industry, we need to lead, not constantly react from a defensive position. Not out of fear, but with knowledge, clarity and strong arguments.

1. Safety

We carried out extensive acceleration tests with selected motors, measuring not only the time but also the quality of the acceleration – and the results were clear: an Avinox M1 with 1,000 W peak power is significantly easier to modulate and safer to ride than a Bosch CX-R with 750 W peak output. Control is more important than peak power. And in that context, the way the motor kicks in plays a crucial role. For example, the sudden jolt in Bosch’s Race mode is so aggressive that even we, as experienced riders, were hesitant to use it on technical climbs, let alone in sketchy situations. And downhill? Forget about it. This mode has no place on production bikes. Sure, pros can handle it. But for everyone else, it’s a crash waiting to happen. And yes, we literally had bikes shoot out from under us, not just as a figure of speech.

2. Measurement methods

On paper, measuring a power limit sounds simple. In reality, lab testing is highly complex and influenced by countless variables. Even the basic execution of a performance test is challenging – but defining the actual threshold values to be used is even harder. A motor system never delivers a constant output. Instead, it generates a sequence of short peaks and fluctuating loads. The key question is: over what time frame is the maximum power defined? A few seconds? 30 seconds? Even longer than that? The result will vary significantly depending on the time window used.

There’s also another major issue that’s barely been considered so far: tolerance ranges between different testing labs. Just like with speed cameras, where a ±10% tolerance is standard, motor performance readings can vary noticeably depending on the test bench, sensors and calibration settings. Without clearly defined tolerances, no regulation will ever be truly reliable or enforceable.

On top of that, any future testing methods must be reproducible and feasible in practice, which requires significant effort, standardisation and a robust technical framework. And finally, the measured power isn’t just a property of the motor alone – it’s heavily influenced by the bike and its setup. Gear ratios, wheels, tires – all of these play a role. Without clear standards, every comparison remains blurry, and every limit test depends on the individual test object.

3. Summary

We still believe that regulation makes sense – especially to put an end to the pointless power arms race. But it needs to be approached with common sense, and more importantly, with a focus on the right parameters. Because at the end of the day, almost no rider out there benefits from even more power if that power isn’t manageable.

E-bike motors – when origin becomes a reason to buy

Vacuum cleaners, TVs, solar panels – we all know the trend: more and more products come straight from Asian manufacturers, price becomes the deciding factor, and Western brands start to disappear. Along with them go jobs, expertise and local value creation. When it comes to performance-grade e-bike motors, we’re still a long way from bargain-bin products like those on Temu – but the direction of travel is looking worryingly similar. For a growing number of e-mountainbikers, the origin of the motor is starting to matter.

More and more riders want to know: who’s behind the system? Where is the value actually created? Am I supporting a regional or European company – or a globally distributed production network?

Because every buying decision is also a statement. Sometimes, even a political one. In our latest Brixen Paper #04, we explore how new market dynamics and business models are changing the bike world, and why we’ve even coined a new term for it: DfM. What DfM stands for, why origin could become a real buying argument in the future, and what the risks are – you’ll find it all in Brixen Paper #04. And yes – this shift is becoming particularly visible when it comes to e-bike motors.

Many e-bike motor manufacturers still keep a large part of their value creation in Europe.

Too much data? Perfect.

Together with DEKRA in Stuttgart, we measured the entire test field – not as lab students, but as equal partners. DEKRA brought their test bench expertise, and we brought deep real-world experience and motor know-how. Ingo spent hours in deep discussion with Ralf and Geronimo – conversations they said they’ve never had at this level with any other magazine. Our shared goal: to further develop lab testing so that it better reflects what actually happens on the trail – and to build a stronger bridge between charts and real ride feel.

What became clear rather quickly is just how complex modern motor testing has become, and how much lab results can vary depending on load and setup. At the same time, Geronimo and Ralf showed us very clearly where motors hit their physical limits, where marketing oversimplifies things, and why some values only make sense when viewed in the right context. “We’ve seen motors that just keep pushing on the test bench, delivering huge power outputs without blinking. You can literally see the drive units pulling against the frame and reaching limits we’ve never encountered before. And it really makes you think – because for most riders, that doesn’t mean a better riding experience. It just means another power label.”

And it quickly became clear why this trend exists in the first place. According to Geronimo and Ralf, it’s driven less by technology and more by market dynamics: “We’re living in a buyer’s market. Brands have to differentiate their products through marketing – and the message is nearly always: faster, stronger, more.”

We’ve seen this arms race in many industries – from automotive to standing desks that shoot from bottom to top in seconds, without considering the user’s safety.

Instead of analysing every data point in detail right here or picking apart the diagrams, we’re doing something more useful: we’re dedicating a full deep-dive article to each topic. In these, we’ll explain what the test data really shows – and what it doesn’t. We’ll uncover surprising results, put things into context, and separate fact from fiction.

What makes a good e-bike motor? Our test criteria

First things first: no one buys a motor on its own – it’s always part of a complete bike. And a motor can only perform as well as the bike it’s part of. Geometry, suspension, software, battery concept and controls all influence the overall experience just as much as the drive unit itself. That’s why we’re being fully transparent about the key factors we used in our evaluation.

Ride Feel

The most important factor remains how a motor feels on the trail. A motor might look great on paper, but if the support is choppy, noisy or hard to control, it loses all credibility. For us, the key points are:

• Traction and fine modulation
• The natural character and magnitude of support
• Overrun behaviour
• How the power ramps in and fades out
• Noise levels, both up and downhill
• Response to pedal interruptions
• Overall fun factor – the emotional sum of all factors
• Reliability – the underrated factor

The market moves fast – sometimes too fast. The result? Products are launched too early, incomplete or prone to issues. Others arrive too late and already feel outdated at launch. That’s why reliability and system maturity are critical criteria, even if they’re hard to measure in a single group test. We ride most motors across multiple bikes, though we don’t have identical long-term experience with every system. What we can do is flag problems when they arise. If issues with the motor, software or hardware show up during testing, we’ll call them out – clearly and directly.

Hardware – the ecosystem makes the difference

A motor doesn’t ride on its own. The remote, display, cables, app, charger and battery handling all form an ecosystem that ultimately determines how practical the system is in everyday use.

System integration shows how cleanly the drive unit and battery can be integrated into the frame – and how tidy the overall bike looks. The remote needs to be intuitive: shape, ergonomics, size, tactile feel and functionality all influence whether you can quickly switch modes on the trail or end up fumbling. The display must be sensibly positioned, well protected, and easy to read. Resolution, screen-to-body ratio and refresh rate all determine how quickly and clearly you can take in information while riding.

When it comes to the charger, usability matters. Fast-charging capability, size and weight must match how and where the bike is used – whether it’s a compact 2A travel charger or a hefty performance brick. Battery concepts are just as important: removable or fixed, high capacity or modular solutions with range extenders or spare batteries – the right choice makes a big difference out on the trail.

A strong system also needs a well-designed app. It should allow for intuitive tuning of the support modes, provide useful info about battery charge status, drive unit and range, offer navigation and GPS tracking, support over-the-air firmware updates, and include features like motor lock, theft protection and smart digital extras.

Tops & flops – what to watch out for when choosing a motor

What impressed us, what drove us mad, and which tiny details either caused spilled coffee or earned a round of high fives? Here are the unsung heroes – and the quiet annoyances – of our motor group test.

Flops

What’s the best e-bike motor of 2026? Our verdicts on all 11 eMTB drive systems

So, which motor takes the overall win? Which one secures our Best Buy or Editor’s Choice awards? Below, you’ll find our clear assessments of the strengths and weaknesses of each motor – so you can decide which one suits you best.

MAHLE M40 in our e-bike motor group test

Let’s start with the MAHLE M40 – an exciting first step from the German manufacturer into the full-power motor segment. In terms of output, compact design and weight, it doesn’t need to hide from the best motors in this test. In fact, it’s one of the lightest yet most powerful drive units in its class. Out on the trail, however, it struggles to fully keep up with the competition. Power dropouts at high cadences and rattling noises on descents hold it back from securing a top spot. That said, the M40 is a solid and forward-looking motor that clearly shows MAHLE’s potential to become a serious contender in the mid-drive market – if they refine the app, display, support modes and overall ride feel.

Bosch Performance Line SX in our e-bike motor group test

The Bosch Performance Line SX strikes a solid balance between a low system weight and strong support for an active, sporty riding style. It demands rider input and rewards high cadences with a powerful kick, embodying Bosch’s vision of engaged, dynamic pedalling. It delivers strong support when ridden actively, enables seamless integration within the Bosch Smart System, and benefits from Bosch’s global service network. However, the SX shows clear weaknesses on steep, technical climbs. Despite its higher peak power, it falls short of its direct competitors in these scenarios and lands in the lower half of our test field.

Bosch Performance Line CX-R in our e-bike motor group test

The Bosch Performance Line CX-R is the most uncompromising motor in the Swabian brand’s portfolio. It delivers powerful output, responds incredibly fast and shines with strong propulsion on steep ramps. But in its designated Race mode, the CX-R demands experienced hands on the handlebars. The support is harder to control and, at times, unpredictable – requiring solid bike handling skills. Unfortunately, crashes and runaway bikes weren’t uncommon during this test. What’s left? You’ll likely end up riding in modes like Turbo and eMTB+, which are also available on the standard Bosch CX. That makes the CX-R’s main selling point far less relevant. What remains is the lighter weight and the badge of riding a dedicated race motor. Whether that’s worth the extra cost and trade-offs in rideability is ultimately up to you.

TQ HPR60 in our e-bike motor group test

More power and better efficiency, without sacrificing its balanced, natural character – with the HPR60, TQ stay true to their roots. And that’s a good thing. The motor delivers the most natural ride feel in this test, paired with seamless integration and whisper-quiet operation. If you’re willing to put in the extra effort, you’ll be rewarded with responsive and, above all, predictable support. Only the technical issues we encountered in some test bikes slightly take the edge off what is otherwise one of the best light-assist motors currently on the market.

FAZUA Ride 60 in our e-bike motor group test

After early teething problems, the FAZUA Ride 60 has finally become a reliable system – and recent updates have brought noticeable improvements to its ride characteristics. The new Mode Control is another step forward, delivering clearer and more intuitive operation. However, long-term competitiveness in today’s fast-moving and innovative motor landscape requires more than just reliability and solid functionality. Even the well-designed smartphone app can’t fully compensate. The biggest weak point remains the HMI – the display and remote – where Fazua still has some serious catching up to do.

Shimano EP801 in our e-bike motor group test

The Shimano EP801 still offers a well-rounded package with intuitive ride characteristics and useful features like automatic shifting when paired with Shimano’s in-house Di2 drivetrain. However, the EP801 doesn’t lead in any category. Look closer and you’ll notice small but significant shortcomings – particularly in the control and display concept, as well as traction, where it lags noticeably behind the stronger competition. To stay relevant in an increasingly competitive market, it’s clear that Shimano need to bring fresh developments to the table – and soon.

Pinion MGU E1.12 in our e-bike motor group test

The Pinion MGU does confirm some common clichés surrounding it: it’s loud and visually bulky – but it’s not significantly heavier than the competition. What it lacks in subtlety, it makes up for with minimal maintenance, a huge gear range, and impressive day-to-day reliability. These strengths shine on long tours and in everyday use, but on demanding trails the system falls short due to imprecise modulation and limited traction. So, the Pinion MGU E1.12 isn’t a do-it-all solution, but it’s a genuinely interesting option for anyone looking for a tough, low-maintenance and long-lasting drivetrain.

S-Works 3.1 in our e-bike motor group test

The S-Works 3.1 stands out above all for its incredible adaptability, and thanks to a range of smart features, you can fine-tune the motor’s character to suit your preferences and riding style. Out on the trail, it delivers impressive traction, consistent power delivery and confident control. In everyday use, it’s backed up by a fast charger, a range extender and the best app in the entire test field. Minor weaknesses only become noticeable when riding aggressively, and while they cost it a few points in the final ranking, they don’t take away from its overall performance. All in all, it’s a well-thought-out, practical and extremely versatile motor system with a strong ecosystem, built into an outstanding bike.

Editors’ Choice

The Editor’s Choice award doesn’t go to the most versatile motor or the one that makes the most sense on paper. It goes to the drive system that truly impressed us with its concept, individuality and unique character. It’s a solution that dares to be different, takes a bold approach – and simply clicked with us. Because we see genuine future potential in it.

maxon AIR S in our e-bike motor group test

The maxon AIR S leaves the light motor segment far behind in terms of performance – despite its compact integration and quiet ride – and instead competes with full-power motors from a much heavier category. While its power delivery at low cadences doesn’t quite match the heavier competition, it strikes an exceptional balance between weight, integration and power – all delivered with impressive efficiency. The biggest drawback? The system’s limited state at launch. Right now, there’s a lack of (relevant) bikes, no functioning app, and no larger battery option. The good news: maxon are already working hard on all of these. The boldness to break new ground, combined with the strong technical execution, wins the maxon AIR S our Editor’s Choice in this group test.

Best Buy

Our Best Buy recommendation is for anyone looking to make a reliable and smart choice. It’s not about price – which we can’t evaluate at the motor level anyway – but about the complete package: performance, usability, integration, app experience and everyday practicality. The Best Buy goes to the motor that’s a safe bet in any scenario – solid, well-balanced, easy to understand, and widely used thanks to its strong all-round performance.

Bosch Performance Line CX in our e-bike motor group test

The Bosch Performance Line CX is the all-rounder of the bunch – the go-to choice for riders looking for a proven system with a mature ecosystem and strong performance across the board. It’s not the quietest, lightest or most powerful motor in this test, but it’s the one that delivers consistently – both in everyday use and on the trail. Smooth power delivery, precise modulation, excellent traction, refined software and a massive partner network for service and updates all make it a standout. That’s why the Bosch Performance Line CX earns our Best Buy recommendation in this year’s group test.

It’s the most well-rounded drive unit in the entire test field, offering an unbeatable combination of all-round performance, everyday practicality and pure riding fun. Whether you’re a beginner or a seasoned pro, whether you’re cruising forest roads or picking your way through technical rock sections – this motor gives every rider exactly what they need, on any terrain.

Avinox M1 in our e-bike motor group test

The Avinox M1 remains the benchmark among full-power motors in 2026 – not because it’s the most powerful drive unit, but because it uses its power the smartest way. With precise modulation, outstanding traction, flawless integration and a powerful ecosystem – including fast charging, a feature-rich app and a premium touch display – it delivers the best overall package in the test and an incredible amount of fun on the trail. That’s exactly why the Avinox M1 holds its place as the best all-rounder in the group and stands out as a true innovation leader, representing the future of e-bike motors like no other. Once again, the Avinox M1 not only takes the top spot in our test – it sets the new standard for the next generation of motor development. A well-deserved test winner!

Conclusions – E-bike motor group test 2026

This motor test makes one thing crystal clear: the future of e-bike motors won’t be decided by peak numbers, but by intelligence, balance and control. The strongest systems in this test aren’t the ones shouting the loudest about power. They’re the ones that deliver their strength with purpose, run quietly, stay efficient and integrate seamlessly into the bike.

The industry needs to move on from outdated superlatives. Torque, peak power or battery size only tell a fraction of the story. What really matters is what you feel on the trail – and how well a motor works in harmony with you, your bike and the terrain.

2026 marks a turning point: Light motors are taking the fight to full-power systems, full-power motors are becoming quieter, smarter and more integrated, and ecosystems are shaping the ride experience more than any number on a spec sheet ever could.

And while some motor manufacturers are boldly pushing the envelope, many bike brands risk losing their identity to their suppliers. Integration, software and user interface are becoming the key points of differentiation – or a trap for those who reduce themselves to being just “parts carriers.”

The key takeaway:
The best motor isn’t the most powerful one. It’s the one that gives the rider exactly what they need – on any trail, in any situation, no matter your riding style.

Power when you want it.
Silence when you need it.
Control when it counts.

And in 2026, it’s this balance that separates the leaders from those still chasing numbers that no longer matter.
