Throttles, ebrake levers, pas sensors, and torque sensors all play a roll in how you interact with the ebike. Torque and PAS sensor automatically power the bike whenever you pedal with an assist level controlled by the CA3's MFSwitch, while a throttle gives manual control. Please see our PAS info page for more details on these options

Even if you choose a PAS or Torque sensor as the primary control, we always recommend having a throttle as well. It can be handy to accelerate in tight situations and is great as a back-up if ever the pedal sensor has issues.  

Regenerative Braking can be controlled with the addition of an ebrake lever, using the throttle to modulate the signal, or it can also be activated through back-pedal crank's rotation.

Front wheel conversion kit for Brompton folding bicycles based around a 350-500 watt Crysatlyte SAW 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 Baserunner controller mounts on a custom bracket behind the fork and does not interfere with the folding.
