With the Phatfour FLS+/FLB+ throttle handle you no longer have to pedal. The handle acts as a throttle that allows you to control the speed. After installation, the pedal assistance is retained, so you can choose whether you use the throttle or prefer to keep pedaling. Mounting a throttle on an electric bike that rides on public roads is not permitted everywhere. We therefore recommend that you consult local legislation. Use of the throttle is at your own risk.
