Avinox has pushed back against concerns that high-power eMTB motors are inherently reckless, arguing that bigger output figures should not automatically be confused with higher speed, lower control or greater risk on the trail.

The statement comes after the launch of the new Avinox M2S motor, one of the most talked-about electric mountain bike drive systems of 2026 so far. With claimed figures of 1,500W peak power, 150Nm peak torque and 130Nm continuous torque, the M2S has reignited a debate that has been building across the eMTB industry for some time: how much motor power is actually useful, and at what point does it start to create awkward questions for riders, brands, trail access and regulation?

Avinox’s position is clear. The company says power is not about excess, but about possibility. In its view, high-power eMTB motors are there to help riders climb steeper gradients, maintain momentum through technical sections, carry extra load and make mountain biking more accessible to riders who may not be served well by a rigid one-size-fits-all power limit.

Avinox says power is about capability, not speed

The key line from Avinox is that power and speed are not the same thing. That matters because much of the concern around powerful eMTB motors comes from the assumption that more watts automatically means faster bikes.

On a UK-legal electric mountain bike, assistance should cut off at 15.5mph, with the bike meeting the wider EAPC rules if it is to be treated like a normal bicycle. That legal framework is still the crucial baseline for UK riders. A motor can have impressive peak output figures, but the question for road, bridleway and trail-centre legality is still whether the complete bike complies with the required limits.

Avinox says its high power output is not intended to push riders beyond legal assisted speed limits. Instead, it argues that the extra power is useful at lower speeds, especially when the bike is trying to overcome high resistance. That could mean a steep fire-road climb, a slow rocky ledge, a wet rooty section or a technical climb where stalling can quickly become a dab, a foot down or a full dismount.

That is a fair distinction. Anyone who rides eMTBs regularly will know that the hardest moments are not always the fastest ones. A bike can feel perfectly manageable on flowing singletrack but struggle on a horrible, greasy, low-speed climb where traction, balance and timing all matter. In that setting, more power is not automatically reckless. Poorly delivered power might be. Smooth, predictable, controllable power is a different conversation.

Why the Avinox M2S has forced the debate

The reason this debate has sharpened is because the Avinox M2S does not look like a small step forward. It looks like a statement.

As we covered in our Avinox M2S motor launch story, Avinox says the M2S delivers 1,500W peak power, 150Nm peak torque and 130Nm continuous torque. The lower-tier Avinox M2 also arrives with 1,100W peak power and 125Nm peak torque. These figures sit well above the numbers many riders have become used to from established full-power systems.

The broader ecosystem is also important. Avinox says more than 60 bike brands are now integrating its latest systems, including names such as Canyon, Mondraker, Pivot, Propain, Rotwild, Unno and Whyte. That takes the discussion beyond one motor, one bike or one brand. High-power eMTB motors are no longer a fringe talking point. They are becoming part of the mainstream performance eMTB conversation.

That is why we previously described the Avinox M2S as remarkable engineering with awkward questions for e-MTBs. The engineering may be impressive, but the industry still needs to be careful about how it talks about power. If every new launch becomes a numbers contest, riders could be pushed towards thinking the best eMTB is simply the one with the most torque and the biggest peak wattage. It is not that simple.

Control matters more than the headline number

For UK riders, the real test is not whether a motor looks dramatic on a spec sheet. It is whether it works on wet, tight, traction-limited trails where too much punch can make a bike harder rather than easier to ride.

Avinox says its system uses intelligent assistance algorithms to deliver power smoothly and predictably. It also points to customisable riding modes and user-adjustable settings, allowing riders to tailor assistance, including maximum output, to suit terrain and personal preference.

That is where high-power eMTB motors can start to make more sense. A powerful motor that can be softened, tuned and controlled is very different from a motor that simply throws torque at the rear wheel. On an eMTB, especially a full-suspension trail or enduro bike, power delivery has to work with tyre grip, suspension movement, rider weight and gradient. If it overwhelms the rear tyre on a muddy climb, it is not helping. If it allows a rider to keep cadence, balance and traction through a climb they would otherwise stall on, it is doing something useful.

This is also why our wider guide to e-MTB motors and batteries explained remains relevant. Torque, watts, battery size and range all matter, but they do not tell the whole story. Ride feel, software, support curves, heat management, reliability and how the complete bike is built around the system are just as important.

The regulation question has not gone away

Avinox also rejects the idea that more powerful motors automatically threaten the eMTB industry. It says responsible regulation and strict compliance matter, but argues that innovation should not be constrained by arbitrary power limits without a clearly explained basis.

That is where the debate becomes more delicate. On one hand, Avinox has a point. A blanket fear of power can oversimplify how eMTBs actually work. A more powerful motor does not automatically mean a faster legal e-bike, and in the right context extra assistance can make riding more accessible to heavier riders, older riders, less experienced riders or riders with physical limitations.

On the other hand, public perception matters. The e-bike category already suffers from confusion between legal pedal-assist bikes, illegal throttle-controlled machines and electric motorbikes being described loosely as e-bikes. The mountain bike world cannot ignore that context. If the industry markets every new eMTB around ever-larger power numbers, it risks making the category harder for non-riders, land managers and regulators to understand.

For Electric MTB UK, this is the important middle ground. High-power eMTB motors are not automatically reckless. But they do need to be legal, controlled, clearly explained and fitted to bikes that have the tyres, brakes, frame design, batteries and software to handle that output properly.

More power is only useful if the whole bike works

Avinox says it takes a system-level approach, looking beyond the motor to tyres, brakes, wheels, frame design, battery architecture, charging systems and software controls. It also says its system can reduce power during gear shifts to help protect chains, cassettes and derailleurs.

That point should not be overlooked. Powerful eMTBs place extra demand on drivetrains, brakes, tyres and suspension. The more assistance a motor can deliver, the more important it becomes for the complete bike to be designed around that force. A motor cannot be judged in isolation.

This is why the growing list of bikes with an Avinox motor matters. If established performance brands can package the system into well-balanced, properly controlled eMTBs, Avinox will strengthen its case that high output can be useful rather than excessive. If the market simply turns peak power into a headline race, the criticism will only get louder.

The sensible answer sits somewhere between the two extremes. More power is not automatically a problem. More power without control, clarity or responsibility is. For riders, the best high-power eMTB motors will not be the ones that shout loudest on paper. They will be the ones that feel calm, predictable and useful when the trail gets steep, slippery and awkward.

Avinox has now made its defence. The next test is whether the bikes using its latest motors can prove that argument on real trails.
