The platform

Engineering depth most factories simply can't match.

Power for every ride. Torque for every gradient. From whisper-quiet 250 W city motors to 4000 W heavy-haul flagships, every TOSEVEN hub motor is wound, geared and sealed for the way that bike is actually ridden.

Inside the hub

Every newton-metre, engineered under one roof.

Stator windings, planetary reduction and the sealed ring gear are designed together — so torque delivery, thermal headroom and ingress protection are built in from the first sketch, never bolted on after the fact.
