When DJI/Avinox launched its first eMTB drive unit, now known as the M1, two years ago, it became the most powerful motor on the market. With 850W of peak power and up to 105Nm of torque, it quickly gained popularity with many consumers equating most powerful with best. But the M1 drive system proved to be more than just powerful. It also received high praise for other elements of its performance, including low weight, tunability, and controlled power delivery.Still, the Avinox M1 motor kicked off what we and others have been calling the eMTB motor power wars. It wasnt long before Specialized came out with its 3.1 and 3.1 S-Works motors on the Levo 4. These stayed below the official US federal 750W nominal power cap, but cranked torque up to 101Nm and 111Nm, respectively. A recent over-the-air update has since turned those peak power numbers up again to 810W for the standard 3.1 motor and 850W on the S-Works version.Similarly, Bosch unlocked more power from its popular Performance Line CX drive units with an over-the-air update, cranking its numbers up to 750W and 100Nm of torque. A second recent Bosch CX over-the-air update has since turned the peak torque up one more time to 120Nm, while keeping peak power at 750W.Both the Bosch CX and the Specialized 3.1 motors have had their power specs increased recently. (Photos/Jeremy Benson)So, when Avinox announced the new, and significantly more powerful, M2S drive unit, many people, myself included, were taken aback by its power specs. With continuous peak power up to 1300W and up to 130Nm of torque, it upped the power ante by a significant margin. And lets not forget the short-term Boost modes topping out at a whopping 1500W and 150Nm of torque. To be clear, the M2S is still limited to 20mph in the USA and 25kph in Europe, so just because its more powerful doesnt mean you can actually exceed that speed limit. Or really even ride it any faster than other eMTBs.Now, Ive never ridden an Avinox-powered bike. But Ive spent plenty of time on the Specialized 3.1 and Bosch CX, both of which I find to have significantly more power than I actually use. So, Ive often wondered who actually needs or wants a motor that powerful? Based on the twenty model avalanche of Avinox M2S-equipped bikes that launched on the same day as the motor system, it seems like MANY brands in the industry are convinced that A LOT of people want a motor that powerful.Cory Benson testing out a new Amflow eMTB with the Avinox M2S drive unit. (Photo/Cory Benson)Until I ride one myself, I cant pass too much judgment. But my colleague Cory Benson can, and has. Hes had the chance to ride both the M1 and M2S drive units, and been quite impressed. Although, he says he rides the latest Amflow in substantially detuned Trail & Auto modes most of the time, really appreciating the ability to adjust power output to his riding style. Plus, hes spent a lot of time on the updated S-Works 3.1 motor too, and describes its peak power output as surprisingly similar to the latest Avinox system. OK, maybe excluding the rocketship Boost button. He talks about how he doesnt feel like the max power numbers are fairly comparable from one eMTB or one e-bike motor to the next.What worries me, however, is the seemingly blatant disregard for e-bike motor power regulations, which, in the U.S. is set at a maximum of 750W (apparently max 750W nominal on a federal level and max 750W peak in some states). Its a slippery slope, particularly in the face of increasing regulations. For example, if/when Californias proposed SB 1167 bill passes, motors with power specs exceeding the 750W limit can no longer be classified or sold as e-bikes in the state.So whats the deal with Avinox creating such a powerful drive unit? It seems a lot comes down to how unclear the power output rules and regulations really are, and whether there is a clear international testing standard for e-bike motor power be it peak, maximum, or nominal power, or even if it is measured directly at the motor or at the rear wheel?Well, the Avinox press team sent out an email yesterday explaining their own power output justification. They titled it: Avinox Pursues Power with Purpose and in it, they make their case for more power in mountain biking. Whichever side of the argument you stand on, its worth a read.As for us, for the time being, were going to keep testing out all the different eMTB powertrain systems that keep popping up, and sharing our own individual real-world thoughts on riding them.From Avinox:In mountain biking, power is often misunderstood. For some, higher motor output raises concerns about safety, trail impact, or component wear. For Avinox, power is not about excess, but about possibility. Power can help more people ride farther, climb steeper, and tackle terrain that might otherwise be out of reach.Our approach to power is rooted in a simple principle: technology should expand access to mountain biking while preserving safety, reliability, and rider control.Power Is About Capability, Not SpeedWhen people hear that an eMTB motor delivers high power, they often express concerns about danger, assuming higher power also means higher speed. In reality, these are two very different things. Speed is what ultimately determines safety risk. Power is the force that helps riders accelerate, especially at low speeds and in demanding situations such as steep climbs, technical ascents, and navigation around obstacles.Avinox systems comply fully with all applicable speed regulations, and we strongly support the implementation and enforcement of speed limits. That means our high power output is not designed to make riders go faster than allowed. It is designed to make difficult terrain more manageable. Whether it is clearing a rocky ledge, climbing a steep incline, or helping a less experienced rider maintain momentum, more power can make mountain biking both easier and safer.Safety Is a Function of ControlAny bicycle can gain significant speed on a descent, whether it is powered or not. This is not unique to eMTBs. The safety challenge in mountain biking is managing speed, maintaining traction, and giving riders the confidence to overcome high-resistance obstacles in complex terrain.Avinox focuses on delivering power precisely when it is needed. Our intelligent assistance algorithms provide smooth, predictable support that helps riders maintain control in various situations. In many cases, more available power improves safety by reducing the likelihood of stalling, losing balance, or being forced to dismount in difficult terrain.Flexible Power for Real-World RidingDifferent riders face different challenges. A steep technical climb requires a different level of support than a flowing cross-country trail. A loaded cargo bike climbing a hill has different needs than a lightweight commuter.Avinox addresses this with customizable riding modes and user-adjustable settings, allowing riders to tailor assistance including maximum output to match the terrain and their personal preferences. This flexibility provides support when it matters most while maintaining efficiency and control.Democratizing Mountain BikingMountain biking should be accessible to more people, regardless of fitness level, body type, age, or physical limitations. High-powered systems help make that vision a reality. With greater assistance, riders can:Conquer steeper climbsRide longer distancesExplore more challenging trailsRecover more easily from technical mistakesBuild confidence fasterFor heavier riders, riders with disabilities, and those hauling cargo, higher power can be considered essential, rather than a luxury. A rigid, one-size-fits-all power limit risks excluding riders who benefit most from additional assistance.Designed to Protect the BikePower only matters if the system remains reliable. Avinox carefully balances performance with durability, avoiding the trap of increasing output solely to claim bigger numbers. Advanced sensors and software continuously monitor riding conditions and adjust torque delivery to protect key components.For example, the system automatically reduces power during gear shifts, minimizing drivetrain stress and extending the life of chains, cassettes, and derailleurs. Smooth, precisely controlled power delivery also reduces wear on tires, brakes, and wheelsets.System-Level OptimizationA high-performance motor cannot be developed in isolation. Avinox takes a complete system approach, optimizing the entire bicycle platform to handle elevated power output, including:TiresBrakesWheelsFrame designBattery architectureCharging systemsSoftware controlsThis integrated engineering ensures that riders benefit from maximum capability without compromising safety or reliability.Higher Power Does Not Threaten the IndustrySome argue that offering more powerful motors could invite regulatory scrutiny or harm the industry. We believe that view oversimplifies a much more nuanced issue. Avinox supports responsible regulation and strict compliance with all applicable laws. At the same time, we believe innovation should not be constrained by arbitrary power limits that lack a clearly explained basis.The industry benefits when manufacturers focus on solving real rider challenges and respecting the diverse needs of users. Progress should be guided by safety, performance, and accessibility, not by assumptions that more power is inherently problematic.Beyond Power: The Full Avinox AdvantagePower is only one part of what makes Avinox different. Our commitment to innovation is reflected in every aspect of the system, including:Compact and lightweight motor designOutstanding power-to-weight ratioSeamless hardware and software integrationIntelligent assistance algorithmsLightweight, high-capacity batteriesFast charging capabilitiesSophisticated system controlsTogether, these technologies create a riding experience that feels intuitive, natural, and remarkably capable.The Future of eMTB PerformanceAt Avinox, maximum power is not about pushing limits for the sake of headlines. It is about empowering more riders to experience mountain biking in ways that are safer, more enjoyable, and more inclusive. By combining high power with intelligent control, system-level engineering, and rider-focused innovation, Avinox is redefining what an eBike motor can do. Because when technology is thoughtfully designed, more power means more opportunity.The post The Avinox Press Team Aims to Justify its Super Powerful New M2S Motor appeared first on Bikerumor.
