    mid drive and front gears

    For my build, I got a left hand spider and used the motor to drive the bike through the cranks and original bike drivetrain (yep... my motor has a 21 gear transmission :D ). I was also able to incorporate a freewheel on the jackshaft to decouple the motor when I am under pedal power alone. If...

    I thought that bike rack piece looked familiar. Very cool idea. So cool in fact that I may need to steal it. Thanks.

    Gallimaufric Build

    Thanks for the feedback yall. The ride back from the office last night went much better after tightening up all the bolts and whatnot. Even with babying the motor, barely pedaling, and sitting bolt upright on this hybrid, I was still able to match my best time on the route from my road bike...

    Gallimaufric Build

    I've been a long time lurker here but now I finally have something to share. Today I was able to complete the inaugral ride on my cobbled hodgepog of an ebike. It's been pieced together from a bunch of old bike and electric scooter parts, as well as a few pieces of hardware purchased for the...

    These look simply amazing, it's obvious how much time you've put into their design. Keep up the good engineering.
