Re: I love my MB, but after seeing this I wonder how they do it.
That was the route I was most likely going to take, either a cheap mtn. bike or a frame with disc brake mounts. I have a full suspension mtn. bike all decked out with nice parts, just no place to put a motor "except for a rear mount". I like having one bike with no motor, so I'll just use the beach cruiser for standard bicycle and use the motor/parts for the other bike.
But I have to wonder how the heck they can offer those scooters for likely less money then it would take me to build my own equivalent MB.
