Sinch ships as a Class II ebike, with pedal assist and throttle going up to 20 MPH. 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 on pedal assist only. Sinch can also operate with the throttle unplugged and removed, should you want to ride in an area where throttles are not allowed.
Aventon ebikes are built to the IPX4 water-resistant standard. IPX4 means that your bike is resistant to water splashes from any direction. This means it’s OK to ride or park your ebike in the rain. It won’t be harmed by spray from a wet road or raindrops. Your ebike is not intended to be submerged or subjected to a pressurized spray. Don’t use a pressure washer or sprayer to clean your ebike.
