So what actually sets Rider Synergy, or RS, apart from a conventional motor or integration concept? Strictly speaking, it’s neither about a particular drive system nor a set of individual features. It isn’t simply a product or a philosophy either. While RS might look like just another technical acronym at first glance, it actually addresses a far bigger question: what should guide the development of a modern E-MTB in the first place? From Orbea’s perspective, that process doesn’t start with the motor, battery or spec sheet. It starts with the rider and the experience on the trail.
And that’s the essence of Rider Synergy: every technical decision should enhance the riding experience rather than just pile more features or chase impressive numbers. Technology is never there just for the sake of it. It should support you without getting between you and the bike. Or, as Orbea themselves put it, technology should amplify the riding experience, not dominate it. You should be in control of the bike, not the other way round.
How did RS come about?
When Orbea began developing the first Rise, the eMTB market was entering an exciting phase. On the one hand, conventional full-support eMTBs dominated the market with 85 Nm of torque and big batteries. At the same time, the first light eMTBs were starting to emerge, promising a particularly natural ride feel with around 35 Nm of torque, smaller batteries and low system weights. For some riders, though, the jump between the two was simply too big and the gap too wide. Full-power bikes often felt heavy and overpowered, while light eMTBs didn’t always give enough support on steep terrain or long climbs.
This was exactly where Orbea saw an opportunity. Rather than committing to either camp, the development team asked themselves a simple question: how much assistance does an eMTB really need? The goal was to create a bike whose support feels like you’re having an exceptionally good day in the saddle, when you’re fresh and your legs are firing. Looking back, the first Rise would probably be described as a mid-support E-MTB, even though the term wasn’t in use at the time.
That’s why the first Rise sat squarely between these two worlds. At its heart was a bespoke RS motor tune for the Shimano EP8 motor, cutting maximum torque from 85 to 60 Nm and fundamentally changing the way it delivered its power. That level of access to the motor controls was anything but straightforward to get: Orbea spent around a year making their case before Shimano finally granted the developers what they needed. The system was paired with a compact 360 Wh battery developed in-house and permanently integrated into the frame. Combined with the minimalist cockpit, relatively low weight and handling deliberately designed to feel like a conventional mountain bike, the result was something that simply hadn’t existed in this form, or at this level, before.
For Orbea, the Rise was an experiment. Would customers willingly give up maximum motor power? Would a natural ride feel matter more than impressive performance figures? And could a modern eMTB succeed without a big display and a cockpit cluttered with controls?
The market gave its answer. The Rise became one of the most successful eMTBs of its generation, proof that plenty of riders had been after exactly this middle ground. Along the way, Orbea gained real expertise, not just in motor tuning and firmware, but in developing their own batteries, integrating electronic systems and engineering light, stiff eMTB frames. Step by step, what began as a single bike grew into a complete development philosophy.
How has the RS philosophy evolved?
The success of the first Rise showed Orbea they were on the right track. At the same time, it was clear that RS was never meant to be a finished project. Rather than settle for the original concept, Orbea kept evolving it, always with the aim of improving the ride without losing sight of the core idea.
Another important milestone came in 2022, when Orbea began developing their own handlebar control unit. The RS HMI (Human Machine Interface) is far more than a conventional remote for switching support modes. Its integrated LED display shows information like battery charge and riding mode, can control the lights when needed, and acts as the central control hub for the entire RS system. Thanks to this close integration, the RS HMI replaces several separate controls, for a cleaner cockpit and less wiring.
The integration-first approach shows especially clearly in the Orbea Smart Dropper. In Smart mode, a single press of the button fully lowers or raises the post. With most droppers, by contrast, you have to hold the lever down throughout the whole movement. It might sound like a minor detail, but on the trail it means your thumb is back on the handlebars much sooner. You can also save a custom intermediate position anywhere between 20 and 80% of the post’s travel, then send the post there with a double press. In doing so, Orbea make far better use of what an electronic dropper post can actually offer than many rival solutions. It also shows that RS goes far beyond the motor and battery, taking the entire riding experience into account.
The system is rounded out by the Orbea Control App. Here you can customise the HMI, the Smart Dropper and, depending on the motor, the support modes and power output. In the long term, the aim is to configure and manage every electronic function in one place. Rather than forcing you to juggle multiple apps from different component suppliers, Orbea want to bring as many settings as possible together on a single, central platform.
At the same time, Orbea have shown that RS is no longer limited to the Rise. An important milestone was set at the start of the year with the Rallon RS 2026, a technology showcase built above all to demonstrate what’s technically possible. It was never intended as a volume model, so production numbers are correspondingly small. At its core, the Rallon RS is a light-support bike in the traditional sense, but it pushes the concept much further than before. Despite its integrated TQ HPR40 drive system, the complete bike weighs about the same as the non-motorised Rallon. The motor is almost invisibly integrated into the frame and runs so quietly you barely notice it.
With the Rallon RS, Orbea took system integration another step further. For the first time, the motor, rear derailleur, suspension and dropper post all draw their power from a single battery. More importantly, the components also communicate with one another. The suspension system knows the position of the dropper post, receives information about the drive unit’s output and can recognise whether the bike is climbing, descending or moving through its suspension travel. This allows the individual systems to adapt their behaviour to the riding situation in the background. The result is a smarter bike that can deliver more performance while requiring less interaction from the rider – a clear example of technology supporting the ride without demanding attention.
The Rallon RS shows just how seamlessly electric assistance and electronic components can be woven into a mountain bike without fundamentally changing its looks or ride feel. Rather than chasing sales, its development was above all about showing how far Orbea could push the RS principle on a purely technical level.
With the WILD LT, Orbea bring the RS philosophy to a modern full-power e-enduro in summer 2026. Despite using the powerful Avinox drive system, the objective wasn’t simply to extract the highest possible peak output. Instead, Orbea focused on maximising the control, responsiveness and immediacy of the assistance.
While the standard Avinox system can deliver up to 1,300 watts of peak power, the WILD LT doesn’t come with this maximum-power setting as standard. Combined with Orbea’s highly reactive RS tune, such an aggressive power delivery would actually be counterproductive on technical terrain, making the bike harder to control, modulate and keep on line. That’s why all four assistance modes are tuned to a maximum of 750 watts.
On the trail, however, the motor hardly feels restrained. Its exceptionally immediate response, high torque and precisely controlled power delivery create a remarkably strong sensation of assistance, while allowing the rider to maintain traction and control on difficult climbs. The 750-watt figure shouldn’t therefore be interpreted simply as limiting the motor. It reflects Orbea’s decision to use the available power in a way that makes the bike more reactive, predictable and controllable for tackling genuinely challenging terrain.
The philosophy behind it remains the same, but its interpretation varies from bike to bike, with each model retaining its own distinct character:
On the WILD LT, the RS designation represents the pinnacle of the range. Much like an M model from BMW, this is where Orbea bring together their latest technologies and highest level of integration. The WILD LT M-LTD RS and WILD LT M-TEAM RS showcase just how far the RS philosophy can be taken from a technical perspective. That includes the RS HMI system, which replaces the standard Avinox controller and brings the bike’s controls fully into Orbea’s own RS ecosystem.
The Rallon RS demonstrates just how discreetly a light-support drive system can be integrated into a modern mountain bike frame, combining maximum integration with minimal noise and an overall weight comparable to the non-motorised model.
The Rise occupies the middle ground as a mid-support bike, combining noticeably more assistance with seamless integration and a natural ride feel.
Light, mid or full support: the technical execution differs considerably between the three. The underlying ambition, however, remains the same. Each platform should feel as natural, controlled and distinctive as possible, in its own unique way.
The four core principles of the RS system
Orbea sum up the RS philosophy in four guiding principles. Rider Focus puts the riding experience firmly at the heart of every decision. Orbea Riding DNA is meant to ensure that every RS bike feels unmistakably like an Orbea, whatever the drive system. Seamless Innovation covers the close integration of hardware and software, from the RS Control App and RS Control System to a shared power supply for multiple electronic components. Cutting Edge Technology stands, finally, for the selective use of new tech, but only where it offers riders a genuine benefit. Ultimately, these four principles sum up the central theme running through this entire article: technology should enhance the riding experience without ever taking centre stage.
That’s exactly why Orbea pursue this approach to development. From the Basque brand’s perspective, more power doesn’t automatically make for a better eMTB. What matters far more is how controllable, efficient and natural the assistance feels on the trail.
That kind of development philosophy takes time, though. As a cooperative, Orbea can plan for the longer term and feel less pressure to chase short-lived market trends. Rather than rushing products to market, their engineers often spend years working with technology partners on individual solutions. The RS Control System, for instance, took almost three years to go from initial idea to market launch. That process is far from standard in the bike industry, where many manufacturers have their roots in traditional bicycle engineering and lean heavily on supplier solutions for electronics and software. Orbea’s aim, then, isn’t to pack in as many features as possible, but to build a cohesive system in which every component works seamlessly with the rest and feels like an integral part of the bike.
Who was Rider Synergy developed for?
According to Orbea, Rider Synergy is aimed at riders who like to ride their eMTB actively. RS was deliberately not designed to make riding as effortless and passive as possible. Instead, the bikes are intended to keep you involved and encourage an active riding style. The assistance doesn’t do the work for you, but complements your own input and abilities. If you value a natural ride feel, precise motor assistance, plenty of traction and agile handling, you’ll quickly appreciate the character of an RS bike. The concept really comes into its own on technical climbs, demanding trails, alpine rides and long days with plenty of vertical metres, anywhere that control matters more than maximum motor power.
RS is less suited to riders who mainly use their E-MTB as a shuttle or simply want to get up a forest road as quickly as possible with minimal effort. That doesn’t mean RS is only for experienced mountain bikers, though. Beginners also benefit from the easily controllable power delivery and natural handling. Experienced trail riders, however, are more likely to notice the finer differences in motor characteristics, handling and integration.
Conclusions about the RS system
With Rider Synergy, Orbea have shown that innovation needn’t mean ever more powerful motors or ever bigger batteries. Instead, the Basque brand had the courage, early on, to go against the grain and build an eMTB that consistently puts the riding experience ahead of the numbers on the spec sheet. At the time, it was a gamble. Today, RS is the foundation of an entire development philosophy.
The bike industry needs more of this. Over the past few years, too many bikes have started to blur into one another, set apart mainly by spec, price or choice of motor. But a bike built to please everyone often ends up with no real identity at all. Orbea show there’s another way: rather than simply developing products, they start with a clear idea of how a mountain bike should feel to ride.
In the end, the bike industry isn’t only competing with other bike makers. It’s competing with every other way people can choose to get around, and to spend their free time and their money. If you want to inspire people to keep mountain biking for the long haul, you have to offer more than keen pricing or a few extra newton meters of torque. What truly lasts are bikes with character, and rides that stay with you long after you’ve hung the bike back up. That is exactly what Rider Synergy stands for, whether or not you ultimately buy into the philosophy.
