Deep Dive: eMTB Warranty Comparison – Who Builds the Bike, and Who Takes Responsibility?

While the industry keeps throwing ever higher torque and watt-hour figures around, reality on the trail paints a completely different picture. Close to 82% of our survey participants now say, in no uncertain terms, that service quality and the long-term durability of their eMTB matter more than the last fraction of motor power. Has the arms race at the checkout finally run its course, and has the era of system responsibility begun?

Anyone forking out €10,000 for a high-end eMTB isn’t simply buying a bicycle. They are buying trust that this complex system of mechanics, software, and battery technology will work and remain serviceable in the long term. But that trust is often based on systems and responsibilities that remain invisible to the buyer until Error 504 starts flashing on the display.

To understand the full extent of the problem, we went straight to the source. We put a structured questionnaire to all 22 manufacturers in our current test field, covering warranty terms, spare parts availability, software support and ownership models. In parallel, we surveyed 354 e-MTB riders about their real-world experiences with service, warranty and purchase decisions.

Local Heroes Under Pressure: The False Security of the Local Bike Shop

Ask the industry, and the world of service is in perfect order. Warranties are being thrown around, and smooth goodwill deals are celebrated as though they were heroic deeds. A look at our latest reader survey shows that a good 72% of eMTBers have already had to deal with a service case. And indeed, around 57% of them had their bike back in rideable condition in under two weeks. Applause for the bike manufacturers? Well, yes and no.

This high level of satisfaction masks a massive structural problem. At present, the industry relies less on clever, sustainable ownership models from bike brands and far more on heroic local shops. More than half of our readers, just under 54%, bought their bike from a local specialist dealer. That dealer acts as a human lightning rod, absorbing the immense complexity of the systems and battling their way through hotlines. When the motor gives up the ghost, suppliers still often replace the entire unit generously rather than carrying out proper, sustainable fault analysis.

A generous run of goodwill replacements in the first two years is not a business model. What happens on day 731, once the statutory warranty has expired? What happens if the start-up behind the smart motor gets acquired? Who maintains the app in year four?

Look beyond the bike bubble: if the ABS fails on an €80,000 car, the manufacturer doesn’t send you off to the supplier. The automotive industry integrates third-party components but assumes full system responsibility toward the customer for the complete product. The bike industry, by contrast, all too often dodges this responsibility. Between lifetime frame warranties, outsourced drive systems, and patchy spare parts availability, the product fragments into individual areas of responsibility. In a serious case, the rider is left to navigate the gaps alone.

Statutory Warranty vs. Goodwill: What It Says on Paper and What Actually Happens

One step back. Before diving deeper into contractual clauses and market mechanisms, it’s worth stripping the marketing language of its mystique. Legally anchored rights and voluntary promises are not the same thing, and the differences, though subtle, are consequential. No legal seminar required: plain language will do.

The „Lifetime” Illusion: What Does a Lifetime Frame Warranty Actually Mean?

‘Lifetime’ is a word that rewards closer reading. Our survey found that nearly 75% of buyers believe it means coverage for the entire life of the bike or a warranty with no time limit. Only around 22% appear to engage with the small print.

Whose lifetime are we even talking about? The product’s? The original buyer’s? The half-life of an Asian motor start-up? In many cases, “lifetime” refers only to the bare main frame. And what good is that if the proprietary charging port or custom motor cover reaches “end of life” after three years?

A second question that marketing language tends to obscure: what does the warranty actually cover? In almost all cases, the ‘lifetime’ promise applies exclusively to manufacturing and material defects. Crash damage, botched drops and trail incidents fall outside its scope entirely.

By no means do all manufacturers in our test field use the term “lifetime warranty”. For all those who do advertise with it, we asked specifically what it actually means. A look at the responses shows that “lifetime” is always tied to conditions freely defined by the brands themselves. In addition, e-bike components are usually rigorously excluded:

Note: The following information is based exclusively on the manufacturers’ written answers to our questionnaire. We reproduce these answers either verbatim or in paraphrased form, but we cannot independently verify their accuracy in individual cases.

• Specialized and Orbea state that they offer a lifetime frame warranty, but link it to mandatory registration within 90 and 30 days respectively.
• GIANT also grants the lifetime warranty on the frame only to the registered original buyer. However, if the bike is used as intended but ridden hard, as in the case of downhill frames, the “lifetime” warranty shrinks to three years.

• Santa Cruz and Yeti grant their warranty exclusively to the original owner. Both understand “lifetime” as classic protection against manufacturing and material defects on the frame. In the event of crash damage, they refer customers to their paid crash replacement programmes. According to Santa Cruz, the lifetime promise also extends to pivot bearings and in-house Reserve carbon wheels. According to the official guidelines, the wheel warranty also applies to riding mistakes and crashes on the trail, not just production defects.
• Atherton likewise limit their lifetime promise to the original owner, but offer an unusual hardware-based approach: „When we say lifetime, we mean lifetime.” If a specific lug breaks in 20 years’ time, the Welsh manufacturer says it will simply machine or print a new one. This is only possible because Atherton produce the frame parts themselves and don’t rely on classic series production stock. For other manufacturers, such a promise would be structurally difficult to sustain.

A look at component manufacturer Race Face shows that the ‘crash voids warranty’ principle does not have to be limited to wheels. The Canadians extend their lifetime warranty across a broad portfolio: handlebars, stems, pedals, cranks and chainrings are all covered in the event of crash damage, provided the components were used within their intended application.

The Second-Owner Check: What Is the Warranty Still Worth When Reselling?

An eMTB is an investment. But what is the warranty promise worth once the bike changes hands? A transferable warranty is the true litmus test for a manufacturer’s confidence in its own product. Build a bike to last ten years, and it should not matter who is sitting in the saddle. Judged strictly by what the extended manufacturer warranty is actually worth to the second owner, three clearly distinct camps emerge.

• Fully transferable (value retention): brands such as Aventon, Haibike and ROTWILD are leading by example. Aventon state that the frame warranty, extended to ten years, can be transferred to the second owner without deductions, provided the original buyer registered the bike on time. According to ROTWILD, the five-year frame warranty remains fully valid for second owners, as long as the change of ownership is properly documented. Haibike states that it offers a fully transferable five-year warranty and also aims to protect resale value via the „digital service booklet” (MyBikeService), which makes the service history transparent.

• Transferable with restrictions (reduction): this is where manufacturers such as AMFLOW, GIANT and Specialized end up. The frame warranty is transferable to the second owner, but the manufacturers use the change of ownership to massively reduce both duration and conditions. Specialized cut the warranty for used-bike buyers from “lifetime” to two years, counted from the original purchase date of the first owner. AMFLOW likewise reduce the original five-year frame warranty for the second owner to two years, counted from first delivery. GIANT grants second owners only a two-year extension from the time of re-registration, provided the original owner had registered the bike.
• Non-transferable (warranty exclusion): for the overwhelming majority of manufacturers in this test field, the extended warranty, including “lifetime” frame warranties, expires the second the bike changes hands. At Atherton, FOCUS, Instinctiv, Megamo, MERIDA, Norco, Orbea, Pivot, Propain, ROSE, Santa Cruz, Sants, SIMPLON, Thömus and Yeti , the extended warranty is explicitly „non-transferable” and applies exclusively to the original owner. A paid crash replacement option that may be offered to second owners, as with Yeti or Norco, for example, is purely a service offering, but not a warranty. In a serious case, buyers in this segment have to hope for the difficult-to-enforce remaining statutory warranty from the original dealer.

The Three Ownership Models in the Big eMTB Warranty Comparison

Ownership is often defined merely by warranty periods and service processes. In truth, it is about something else: anyone spending several thousand euros on an eMTB is buying the assurance that the bike will work, can be serviced, and will remain usable in the long term.

After an intensive analysis of all 22 manufacturer responses from our big group test, one thing becomes clear: unified system responsibility is, in most cases, an illusion. Instead, three very different types of ownership models can be derived. To help you know what you are getting into before buying, we have sorted the market:

The Integrated Model: The System Boss

In this model, the manufacturer takes ownership of the entire product: mechanics, motor, battery cell and all. Communication is centralised and the customer deals with one party.

• AMFLOW: according to their own statement, AMFLOW’s manufacturers explicitly view the statutory warranty „not as the end of our responsibility, but as its beginning.” The manufacturer states that it guarantees the availability of all model-specific components, including motor mounts, battery covers, and display interfaces, although it does not name a concrete period in years. As a measure to support this, AMFLOW refers to a compensation programme for the EU market: if a required spare part cannot be shipped within seven days of the service case being submitted, customers receive a voucher worth €50 according to the manufacturer. For every further delay of seven days, another voucher of the same amount is added, with no upper limit.

• Specialized: the American bike colossus also claims „system responsibility for motor, battery, and electronics” for itself. However, when asked more detailed questions, the Americans deliberately refrain from making concrete year-based promises about spare parts and updates. They ask for understanding that they don’t wish to comment in greater detail. Instead, the brand points to its operational dealer service network and unified diagnostic tools in order to keep downtime to a minimum. It is a well established system that requires a high basic level of trust in the brand from the customer, since guaranteed deadlines are missing on paper.

The Dealer-Centred Model: The Single Point of Contact

Here, the specialist dealer, or a manufacturer-owned service network, is the absolute hub. The manufacturer provides the infrastructure in the background, but deliberately coordinates through its broader network. The shop therefore absorbs the complexity for the customer.

When comparing the original answers from FOCUS, Pivot, ROSE, Haibike, MERIDA and Thömus, one thing quickly becomes clear: on paper, the marketing departments may use slightly different vocabulary, but in real-world practice for the end customer, the concept means exactly the same thing for all these brands: „Go to your shop, they’ll sort it out for you.”

In the event of defects with the motor or battery, the customer isn’t simply fobbed off directly to Bosch, Shimano, or FAZUA. Nevertheless, there are subtle differences in the exact handling, particularly in how strongly the manufacturer itself remains involved:

• The manufacturer as active coordinator: ROSE states that, in cases involving combined problems with suppliers, it actively steers things from the background: „We always try to find our own solution first. Only if we no longer know what to do or cannot make progress ourselves is the manufacturer [third-party supplier] involved. Our role then remains actively coordinating.” The customer goes to a store or one of more than 250 service partners in the DACH region, but internally, the brand remains in charge.
• The specialist dealer as manager: other brands delegate the organisational work even more clearly to the shop. Pivot makes clear in its responses that all complaints run strictly through the dealer network: „Our specialist dealers take on the coordinating role.” FOCUS also sums up this industry promise concisely, stating: „One contact for all problems!” The contact meant here is explicitly the local FOCUS dealer.

To avoid leaving frontline dealers exposed, the brands point to expanding infrastructure. Haibike states that its „MyBikeService” platform has already established a digital service booklet giving dealers access to the complete service history. MERIDA says it plans to expand its dealer training programme further, while Thömus relies on in-house service packages, partly free of charge and including suspension setups, to keep buyers connected to their local shop. In this model, the dealer acts as a genuine shield for the customer. Whether that holds up in practice depends, logically, on the qualification and motivation of the individual workshop.

The Delegated Model: Frame Assembler vs. Conductor

Structurally speaking, this model is the current industry standard: the bike manufacturer builds the frame and buys in the motor from Avinox, Bosch, Shimano, TQ, and others. If the drive system fails, responsibility lies with the supplier. However, within this category, there are massive differences in transparency and customer guidance.

• The conductors (controlled communication): some brands delegate the technical solution but state that they do not leave the customer alone. Propain say they want to act as coordinator and examine individual goodwill options, „even if the system manufacturer formally rejects a claim“. SIMPLON state that, for systems being phased out, it proactively looks for upgrade paths to successor models, for example from the TQ HPR50 to the HPR60, rather than leaving the customer stranded with an outdated system. Brands such as Instinctiv, Megamo, ROTWILD, Atherton, Aventon and Sants also fall into this camp. Instinctiv phrases this approach as follows: the technical solution comes from the motor manufacturer, maxon, but „we are involved throughout the entire process to make it as smooth as possible.” Megamo and Sants likewise emphasise that they actively coordinate the service process and state that, in some cases, they even maintain their own buffer stocks of supplier components to avoid long waiting times.

• The pure frame assemblers (hard delegation): brands such as GIANT, Norco, Orbea, Santa Cruz and Yeti make things crystal clear: electronics, motor, and battery are handled under the conditions of the respective motor manufacturer. When asked about updates, Yeti answers honestly, but with a shrug: „This is determined exclusively by our suppliers and we have no influence over it.” The most brutally clear answer comes from one of the manufacturers we surveyed, stating bluntly what the delegated model essentially means: „There can be no ‘system responsibility’ when different producers cooperate.“

Special Case Prototype: ABUMS

One manufacturer deliberately falls outside this grid: Spanish start-up ABUMS is still at the very beginning of its journey, with only two existing prototypes at present, one of which is in our test. Even though the formal warranty conditions still need to be finally defined, the brand presents the outlines of a completely independent, conceptual ownership model. One proposed solution is purely mechanical in nature and offers a notable alternative to looming technological obsolescence: instead of relying on PR warranties, the start-up aims to build on the unlimited repairability of steel frames and uses replaceable, CNC-machined motor mounts, or „brackets”. The aim of the frame design is this: if the current drive system is outdated in five years’ time, you swap the bracket and install the next-generation motor instead of throwing away the frame.

Hardware Eternity vs. Software Mayfly

The most expensive ownership model collapses in on itself if two completely different life cycles aren’t separated. A bike that’s mechanically robust enough for ten years of hard trail use is of no use at all in the end if the digital ecosystem pulls the plug after three years and the smartphone app crashes.

The Battery Lottery: Who Guarantees Specific Remaining Capacity?

The problem begins with one of the most expensive wear components: the battery. In our comparison, manufacturers’ capacity promises are worlds apart. While AMFLOW guarantee on paper that the installed Avinox battery will still have at least 80% of its capacity after two years or 500 full cycles, customers often search in vain for hard numbers elsewhere. Megamo refer to internal tests in which around 90% residual capacity was measured after 500 cycles under standard charging, but immediately makes clear in its answers that the actual battery warranty conditions are based exclusively on the official guideline of the system supplier. Others remain vague: GIANT merely names an upper limit of 600 charging cycles without specifying a percentage, while according to its warranty conditions, Orbea even exclude gradual capacity loss completely from coverage.

And the rest of the 22-brand test field? Although we explicitly asked all manufacturers in our questionnaire about guaranteed remaining capacity, the answer is mostly sober: the overwhelming majority of brands merely refer to the blanket conditions of the system suppliers, or left this specific detailed question completely unanswered. Yet the figures certainly exist: Bosch, Shimano, and co. provide their customers with technical data sheets containing exact information on cycles and residual capacity. Anyone who doesn’t pass them on is making an active decision.

Conclusions: How Important Is Ownership to You?

The arms race at the checkout has not had its day yet. But our data show unmistakably that buyers are already one step ahead of the industry in their thinking. The question is no longer whether ownership will become a purchase criterion, but when manufacturers will finally start taking it seriously.

Conclusions for our Readers: Know the Ownership Model of Your Dream Brand!

Will I still get a new motor cover in five years, or will I have to tape my frame shut with gaffer tape? Do you know the ownership model of your dream brand? Anyone who knows in advance whether their manufacturer assumes system responsibility itself, coordinates it through the dealer, or passes problems straight on to the suppliers will not face any nasty surprises when something goes wrong and will at least know who to contact.

Impulse to the Industry: Responsibility Cannot Be Outsourced!

Of course, nobody buys an eMTB solely because of the warranty terms. But in a market where bikes are becoming increasingly similar on the trail, ownership is becoming the differentiator that determines the second purchase.
Anyone charging premium prices must deliver premium responsibility. In 2026, it’s simply no longer enough to build excellent bikes and shrug when problems arise. „There can be no system responsibility when different producers cooperate.” We are deliberately leaving the author of this quote anonymous here, because it would be unfair to pillory one individual manufacturer for this openness. However, this honest but sobering attitude structurally reflects the reality at many brands. From the customer’s perspective, though, it’s unacceptable.

To avoid any misunderstandings: running a delegated ownership model is legitimate. Not everyone can or has to build their own closed ecosystem. But, for heaven’s sake, make it transparent! Take on the conductor’s role, create upgrade paths for outgoing components, and stop letting the end customer starve as a ping-pong ball between hotline queues and the warranty departments of the motor giants.

The local bike shop remains irreplaceable in all of this. As FOCUS quite rightly notes: „A creaking bearing cannot be fixed over the phone.” The dealer is the most important interface to the rider. But they cannot keep covering for unclear industry processes forever. They need a strong foundation, fast spare parts, and crystal-clear support structures from the manufacturer.
