Pre-Motorized Bicycle Information.Before you mount that engine to your bicycle frame, you'll want to know if the bike is ready for the engine! Ask our experts here for advice on what motorized bicycle engines perform well on what bicycles.
I have an old Western Flyer cruiser frame that I am trying to resurrect into a new project but as always I've run into a glitch with a non-standard item. As near as I can tell the inside diameter of the seat tube is 20mm which puts it just slightly over 3/4". As far as I can tell the smallest seat post manufactured is 13/16". So is there some supplier out there that has 3/4" seat posts that I have been unable to find, or should I just buy some 3/4" o.d. steel tube and cut it to length? Anybody else ever tun into this?

You could probably just make your own. It will take a while to find a supplier and it probably will not be cheap.
My Western Flyer dates to 1976, so there are no unusually sized parts on it.
