Technical Overview
Sinch 2.5 ships as a Class II ebike, with pedal assist and throttle. Sinch 2.5 will also operate with the throttle unplugged and removed, should you want to ride in an area where throttles are prohibited. 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 your ebike in light rain. It won’t be harmed by spray from a wet road or raindrops. Your ebike is not intended to be exposed to prolonged rain, be submerged, or subjected to a pressurized spray. Don’t use a pressure washer or sprayer to clean your ebike. *Max range determined using PAS Eco throughout flat terrain with a rider weight of 160 lb.
