On April 9, 2026, DJI’s e-bike division Avinox unveiled two mid-drive motors that, on paper, blow past anything Bosch or Shimano currently offers for electric mountain bikes. The flagship M2S is rated at 1,500 watts of peak power and 150 Nm of peak torque, with 130 Nm available continuously. The smaller M2 checks in at 1,100 watts peak and 125 Nm peak. Avinox says 60 bike brands have signed on to build around the new hardware, though it has not named a single one of them.
Those numbers demand context. Bosch’s Performance Line CX, the motor found on many top-selling e-mountain bikes, tops out at 85 Nm of torque. Shimano’s EP801 matches that figure. If Avinox’s claims hold up under independent testing, the M2S would nearly double the torque ceiling set by the two dominant players in the market.
From drones to drivetrains: a fast evolution
DJI, best known for its Mavic and Air consumer drones, surprised the cycling industry when it debuted the original Avinox Drive System at Eurobike in July 2024. That first motor was rated at 105 Nm of torque, weighed 2.52 kg, and paired with 600 Wh or 800 Wh battery packs. It offered five assist modes, including a 30-second Boost function and an app-controlled auto-assist feature. For a company with zero history in bicycle drivetrains, the spec sheet was ambitious.
Less than two years later, the M2S represents a 43 percent jump in peak torque over that original unit. Leaps of that size in a single product cycle are uncommon in the e-bike motor world, where Bosch and Shimano have typically added torque in single-digit increments across generations. That pace of improvement does not make the claim false, but it raises fair questions about how peak torque is measured, under what cadence and load conditions, and for how long the motor can sustain it before thermal limits kick in.
Between the two hardware generations, Avinox pushed a firmware update in May 2025. The company’s official newsroom lists device version V00.11.03.04 and Avinox Ride App v1.3.3 as part of what it called “significant performance and intelligence enhancements,” though no comparative benchmarks were published alongside the update.
What we still don’t know
The biggest gap is independent verification. Every torque and wattage figure for the M2S and M2 traces back to Avinox’s own press release, distributed through PR Newswire. No third-party dynamometer test, no rider review from a credible cycling publication, and no teardown from an outside engineer has surfaced as of late April 2026. Until someone straps the motor to a test bench, those headline numbers remain manufacturer assertions.
The 60-brand partnership claim is similarly thin. The press release does not identify which companies have committed, what bike categories they plan to target, or when finished bikes will reach consumers. A large number sounds impressive, but without named partners and ship dates, it is impossible to tell how many of those agreements will produce high-volume production models rather than limited runs or trade-show concepts.
Key specs that buyers care about are also absent from the announcement. Avinox did not disclose the weight of either new motor, the compatible battery sizes, or suggested retail pricing. For comparison, the original Avinox unit weighed 2.52 kg, lighter than the Bosch Performance Line CX at roughly 2.9 kg. Whether the M2S maintains that weight advantage while nearly doubling the torque output is an open and important question.
The branding puzzle
A subtle shift in the April 2026 announcement may matter more than it first appears. DJI launched the original system at Eurobike 2024 under its own corporate name. The new press release positions “Avinox” as the announcing entity, not DJI. Whether this reflects a formal corporate spinoff, a subsidiary rebrand, or simply a marketing decision is not clarified in any available filing. Avinox’s website still references DJI technology, and DJI appears to remain the parent company, but the relationship is less transparent than it was two years ago. Buyers and shop owners should keep that ambiguity in mind when evaluating warranty support and long-term parts availability.
Regulatory questions loom
Avinox emphasizes peak power, but regulations care about nominal output. In the European Union, the EN 15194 standard caps continuous motor power at 250 watts for pedelecs that can be ridden without special licensing. In the United States, Class 1 and Class 3 e-bikes are limited to 750 watts of nominal power. The M2S press release does not state a nominal power rating or explain how the system will be configured for different markets. That leaves open whether the same unit will ship in software-limited variants for road-legal trail bikes or be reserved entirely for off-road-only models where power caps do not apply.
What this means for riders
If the M2S performs anywhere close to its claimed specs, it represents a genuine shift in what a mid-drive e-mountain bike motor can deliver. A 150 Nm motor could make steep, technical climbs that currently require careful line selection and momentum management feel meaningfully more accessible, particularly for heavier riders or those hauling gear on backcountry trails.
But “if” is doing heavy lifting in that sentence. Peak torque figures tell you the theoretical ceiling of a motor’s output, not how it feels under your feet on a 20-minute climb in 90-degree heat. Noise, pedal feel, heat management, integration with dropper posts and shifting systems, and long-term reliability all matter at least as much as a torque number, and none of those qualities can be evaluated from a press release.
For riders weighing an upgrade or a new bike purchase, the safest read on the April 2026 announcement is this: Avinox has made an ambitious statement of intent that puts real pressure on Bosch and Shimano to respond. Whether it delivers on that ambition will only become clear once independent testers ride production bikes built around the M2S and M2, and that has not happened yet.
