Technical Overview Ramblas comes out of the box as a Class I ebike, with pedal assist. Aventon’s Ramblas is built to the IP67-rated standard. IP67 rating means it’s protected against the effects of immersion in water to a depth between 15 cm and 1 meter. IP67-rated products are referred to as waterproof vs only water-resistant, so you can cross creeks, and ride in rain and mud without worry. Aventon ebikes are not intended to be subjected to a pressurized spray. Do not use a pressure washer or sprayer to clean your ebike.
