So a guy named Cam Woods created this really really dope DIY motorized bike kit that you can assemble yourself using a XR50/pitbike engine and standard mountain bike components and it’s called Motoped. Motoped is one of the dopest motorized bicycles around and it’s very durable form the video that I’ve seen:
What’s also cool is you can also run either pedals or pegs on this bike.
There’s also a footpedal brake assembly that converts a mountain bike hand brake into a foot pedal brake. This will allow a larger motor with a manual clutch to be run in the motoped, How dope is that.
