Hoi! In researching my new interest, I found a couple of very informative forums. Joined one and just signed up for this one. At present, I ride a 2 stroke 49cc 03 Geely to work and have a 4 stroke Dayang on the "workbench". Like many, commuting just got too expensive on gas. I only work 2 miles from home so didn't see any sense in using a car. Either ride a bike or a scooter. I just retired my 80's vintage Fuji hybrid and bought a Giant from a UH student going back home on the mainland. It's not good for motorizing, but my old Fuji frame is and will probably start rebuilding it soon. I just need to do more "homework" on engine and kit types that are available and affordable. Cash is tight, so I was also tossing around the idea of retrofitting my frame with the Geely motor or a 4 stroke off my lawnmower. So far, experienced builders confirmed it would not be feasible or affordable. Looks like somekind of 2 stroke kit is going to be looked at. Anyway, will be reading up on what y'all have to say about anything related to motorized bikes.
