"Too tall" would be an understatement. It would not move me on the bike no matter how much gas I gave it. I tossed the jackshaft mount in the trash and ordered a 56T sprocket. I then removed the rear disc brake and am relocating it to the front tire. How good or bad is the Grubee 4G belt drive? That's what I'm looking at now.
