Summary

    Front wheel conversion kit for Brompton folding bicycles based around a 250-500 watt Direct-Drive Crystalyte motor laced in a 16" ETRTO 349 rim. Motor axle is 75mm long with a 3/8" 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 compact Baserunner mounts on a custom bracket behind the fork and does not interfere with the folding. The Brompton SuperH kit with your choice of UART display, battery pack, and PAS/Torque sensor options. The basic display kits have a modern looking screen but are not as customizable as our Cycle Analyst systems. Please see our Kit Styles page for more details.  

    For details on the PAS/Torque sensor selection, see the Advanced PAS Kit Info Page

    See our Brompton Kit Info Page for full description and details.
