Re: List of motorized bicycle gearboxes
Hi mezzenger, I am not in tune with everything being made, BUT I do know that EZMotorbike makes the Q-matic, and the Pacesetter drives especially to fit HauSheng and Honda GX50H 5/8 keyed shaft engines, also the internal clutch model of the Hau Sheng (with special adapter we make).
The Pacesetter is also available drilled to bolt right on to the Harbor Freight 79cc Greyhound, and the 99cc predator models.
It is adaptable to many other engines, but these are the patterns I am currently aware of. I am currently interested in mounting one to a 3.5 HP Briggs and Stratton Vertical tho I am not sure how I will bolt on to the old engines that I currently have.
I hope this helps answer your question.
