US Spec Throttle
This Super73 throttle can be added to your Super73 ebike to allow the rider to accelerate with their thumb. Plugging in the throttle will de-restrict the motor to 500W and remove the speed limiter under power, so the bike can reach a speed of 32k/h.
It’s a valuable accessory that unlocks the ability of the Super73’s, however by law you will not be allowed to ride with a throttle in public spaces, like roads, footpaths or cycle ways.
This throttle can only be installed and used on private property where there is no public access.
