Front Brompton Kit with NSM motor

Front wheel conversion kit for Brompton folding bicycles based around a 250-400 watt Crysatlyte NSM motor laced in a 16" ETRTO 349 rim. Motor axle is 75mm long with an M10 axle ground to 8mm on the flats, and fits in the Brompton fork with no modifications. A pair of torque arms mate with the dropout's anti-rotation hole to prevent spinout.

The 15A controller mounts on a custom bracket behind the fork and does not interfere with the folding.

Options to purchase either a basic package with a throttle and eZee LED console, or a more advanced system with a V3 Cycle Analyst and either a magnet ring PAS sensor or a TDCM Torque Sensing bottom bracket for automatic assist modes. Installation of the TDCM torque sensor does require drilling a hole in bottom bracket shell.
