jackshaft was the rear axle from a Schwinn/Izip/Currie. new sprocket welded to old hub housing. total gear reduction should be 7:1. thinking about disc brake on differential housing
01-13-08 batt box is finished. Old alum signs beat into shape, insulated w corrugated plastic - still waiting for dorks @ pharmacy to process my last photos
02-26-08 dorks @ pharmacy crashed last roll of film - no new photos yet - building rack for batt box
06-15-08 crimping connectors on cables - need to experiment with throttle to figure out which wires go to controller.
08-08 First test drive resulted in trouble with controller - vendor not helping much. Did get more pics tho'. Result of Hurricane Ike the whole house is a mess & I can't do anything right now.
04-09 Bill gave me an Amigo shopping cart that he pulled out of a dumpster and I scavenged the controller from it. It works fine but now I have a problem with the chain jumping off the sprocket.
