It can also be easily modified into a class III ebike and can go up to 28 MPH on pedal assist. The Aventure 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. Which 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.
