A replacement rotor for e-MTBs running the DJI Avinox drive system, including Amflow's Avinox-powered bikes, this 6-bolt disc from Tektro has the Avinox tone wheel built into the rotor itself. The ring of slots around the centre is the speed sensor target for the motor, so there's no separate sensor ring to fit, align or knock out of place.

It comes in 180mm and 203mm diameters. The bigger 203mm rotor gives a longer lever arm and more braking power, which makes a real difference when you're bringing a heavy e-bike to a controlled stop from speed on long, steep descents. The 180mm suits rear brakes or bikes specced with smaller rotors.

Please note this is a sensor-specific rotor: a standard rotor won't give the motor a speed signal. Check that your bike uses a tone wheel rotor, and which diameter your frame and fork are set up for, before ordering. If you're unsure, get in touch and we'll help you confirm.
