Maxon BIKEDRIVE AIR S

The lightest full-power e-bike motor.

Developed and built in Switzerland by Maxon — the same precision drives used in robots and Mars rovers. Just 4.4 lb and 90 Nm, invisibly integrated into the frame for a natural ride feel and builds under 37 lb. EU-legal.

The previous-generation AIR ran a 7.7 lb system at 40 Nm on a 250 Wh battery. The new AIR S more than doubles torque and power at a lighter motor weight — full-power feel in a light-e-bike package.
