Sinch ships as a Class II ebike, with pedal assist and throttle. If you are riding on private property or in an area without ebike speed restrictions, the speed limit can be modified in the settings, and Sinch's powerful motor can go up to about 4 MPH above the factory set top speed. Sinch can also operate with the throttle unplugged and removed, should you want to ride in an area where throttles are not allowed.
