Non-negotiable at 3000W. Add our Heavy-Duty Torque Arms ($22) at checkout.

At 3000W, your frame needs to handle serious stress. Steel frames are strongly preferred. Aluminium frames with reinforced dropouts may work — contact us if unsure. Carbon frames: not compatible.

Installation

Rated: Advanced. This is not a beginner kit. If you haven't installed a hub motor before, we recommend starting with a lower wattage or having a local e-bike mechanic assist with the build.
