Finishing the Greyhound Build!!!

Elmo · #1 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.

sound like it'll work good

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.

Just thought about it, you have an empty BB. How cool is that! Could do so many things. Shifter or just reduction. Very cool.

Dan I have plans for a jackshaft there. Ron suggested making a shifter out of it. Do you think the Greyhound has too much power for a shifter setup? I am getting up in age but my mind is still young and I still like to hit the gas every now and then.
