A mounting was engineered to mount the 65 tooth rear sprocket to the drive wheel this is driven by the 12 tooth cog on the motor. A motor mounting bracket was fashioned and welded to the bottom of the rear truck, so the motor tilts with the truck.

Cable controlled throttle via a bike brake lever and plunger pot with a small contact switch on the control lever to flick to reverse which also serves as the brake
