    Exit, you should ask Justin if ebiking across Canada was a NO EFFORT, cheat. I've done cross state rides on a Road bike and know it would take more of a different kind of effort to do it on an ebike.

    Yes Jack. There is a freewheel on the left (motor drive) side of the wheel.

    I guess anything is possible, but these systems only increase chain tension by a factor of two. They MATCH the force the rider applies, doubling it. It's a poorly maintained bike that doesn't have...

    Something NEW: Sunstar SO2
