Can You Delimit the New Avinox M2 and M2S? 2026 Tuning Guide
Share
Short answer: yes. If you're searching whether you can derestrict the Avinox M2 or M2S, the same wheel-sender approach that worked on the M1 still applies to the newer DJI motors in 2026. But "it works the same" doesn't mean nothing changed between generations, so let's go through what's actually different on the M2 and M2S before you buy.
What's genuinely different on the M2 and M2S?
Most online chatter treats the M2 and M2S as a straight copy of the M1. They're not identical bikes, and the parts that matter for tuning are worth separating from the parts that don't:
- The newer motors are tuned for a different feel, with refreshed assist mapping and ride modes. That's about how the help is delivered, not a new way of measuring your speed.
- The speed-measurement principle is unchanged. The system still works out how fast you're going from a wheel-speed signal, and it still tapers assistance toward the EU pedelec limit. That's the hook a wheel sender uses, and it's why the method carries over.
- DJI keeps iterating the app and firmware. New screens, new diagnostics, occasional behaviour tweaks — but the user-facing settings still don't expose a derestriction unlock on any of these motors.
If you want a deeper side-by-side of the hardware generations, our Avinox M1 vs M2 vs M2S comparison breaks down where the differences actually land.
Does the wheel-sender method work on the M2 and M2S?
Yes. A wheel sender reports a lower wheel speed back to the motor, so the system reads you as travelling slower than you really are and keeps assisting past the factory cutoff. Because that's done in hardware — sitting inline with the speed sensor rather than touching DJI's software — it transfers cleanly from the M1 to the M2 and M2S.
Our Avinox delimiter chip is built to fit the M1, M2 and M2S motors, plus the Amflow PL frame they're commonly fitted to. No firmware hacks, no rooting the app. If you're weighing this against software methods, our write-up on chip vs app tuning covers why a physical device tends to be the more durable choice.
Will a firmware update undo it?
Because the sender is a physical device on the speed sensor rather than a software exploit, app and firmware updates don't typically disable it the way an update can quietly close an app-based workaround. That independence from DJI's software is the main practical reason people pick a sender for the M2 and M2S specifically — the newer motors get updates more often.
What changes when you derestrict — and what doesn't
- Assistance continues past the factory cutoff, so the motor keeps helping where it would normally taper off.
- Your speedometer will read lower than your true speed, because the system is being fed a reduced wheel reading. Factor that into range estimates and ride planning.
- It's reversible. Remove the sender and the bike returns to stock behaviour, which matters if you ever need it back to factory.
- It does not boost raw motor power. We won't quote torque, wattage or top-speed figures here — for those, always check DJI's official specs for your exact motor. A sender changes when the assist stops, not the motor's underlying output.
Installation on the newer motors
Fitting on the M2 and M2S follows the same routine as the M1 — it's an inline connection at the speed sensor, no disassembly of the motor itself. We've written the full walkthrough in our Avinox wheel sender install guide, and riders on the Amflow PL frame will also want the frame-specific notes in our Amflow PL tuning guide.
The honest part: legality and use
A derestricted Avinox is for private land / off-road use only. We can't and won't claim it's road-legal — derestricting changes your e-bike's classification, and the rules vary across Spain and the wider EU. Before you decide, read our honest take on whether it's legal to delimit an e-bike and the broader guide on how to delimit a DJI Avinox e-bike, then check your local regulations. Be honest with yourself about where and how you'll actually ride.
FAQ
Is M2S tuning different from the M1?
The wheel-sender principle and the installation are the same, and the same chip is designed to cover M1, M2 and M2S — so you don't need a different product for the newer motors. What differs between generations is assist feel and firmware, not the way the bike measures speed.
Does derestricting damage the motor?
The sender doesn't overdrive the motor or force it beyond its design — it changes the speed value the system reads. Ride sensibly, keep it off public roads, and consult DJI's official specs for the limits of your specific motor.
Can I switch it back to stock?
Yes. Removing the sender returns the bike to factory behaviour, which is handy if you ever need the original setup back.
