All of our bikes can be pedaled just like a traditional bike without any motor assistance. The geared hub motors on the RadRover and RadMini free spin around the axle, meaning they do not provide any resistance when unpowered. The direct drive motor on the RadWagon and RadCity does have a small amount of resistance when unpowered, but most people do not notice or feel held back by it.
By turning the bike off, or switching to Pedal Assist Level 0, you are able to pedal and ride the bike as you would any normal pedal bike while shifting gears to accommodate terrain.
Pedaling our bikes without motor assistance will require slightly more effort from the rider compared to a traditional bicycle (especially at standstill) as you have to overcome the weight of the bike. But once you get the bike moving, it's very easy to maintain speed!
