I just bought a 1977 Batavus HS-50 with a nice solid frame. Unfortunately, there are a few things I didn't know about before buying it. Its missing a decent amount of parts from the engine and in is the 20mph motor.
I'm considering swapping the engine to make parts easier to find and to boost power a bit. Does anyone have any experience with this? What engine would best for the frame? And where should I get an engine, off of a another bike from craigslist?
Thanks in advance
