I've seen some of you guys talk about e-bikes i was wondering if anybody has experience with the small gasoline engines such as what they market at BikeBerry ? I have zero experience with anything like that, but my brother has always been pretty mechanical (building dune buggies and such as a kid and he's basically the family mechanic now) and I think we could build what I'd need IF it's a practical solution. I live on a hill in a very hilly town with MUPs down in the valley along the river. getting down there is easy enough BUT it would always require a serious climb to get home. I can get a trailer from Tractor Supply to transport my trike for $600, i don't expect that i could put an engine on for that price but if it wasn't completely out of reach it might be a fun project... thoughts.
