Starting Greyhound Build

Elmo · #1 (**permalink**) 11-05-2009, 04:07 PM

Well I have one of those 79cc HF Greyhound engines so I thought I would build a bicycle for it. I have acquired 2 of the inexpensive mountain bikes as donors. I intend to cut 1 behind the seat post and the other in front of the seat post amd join them together with tubing so I would have an easy place to mount the motor. Sort of a mid engine deal.

This MB will be my winter project. I want to use a centrifigal clutch and gear it so it will hit 30 mph at 4000 rpm.

I plan to build it like this. Connect the two pieces with chromoly tubing and mount the engine with a centrifigal clutch. Get some bearing adapters made for the bottom bracket and use it for a jackshaft. Build a wheel with a freewheel on the left side. Anybody see anything wrong with this plan? Comments welcome.
