Hey guys, Glad to have discovered the world of motorized bicycles. I'm considering putting one together to save huge on gas on my commute to work. Right now, I'm looking at a Grubee GT4 Starfire 66cc engine. Are they any good? I'm looking for some dependability as I will probably be using it as a daily commuter (5-15 miles one way). Any recommendations? Glad to be here! Looking forward to this project Currently looking for a 60-70's Schwinn Tiger or Jaguar. . . I think I'm going to go for that board track look.
