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 Plastic ammo box from Northern Tool is perfect size for 4 brick-sized batteries. New wire cargo basket is from shopping scooter 10-17-10 First real test flight w/o breaking anything. Rode around the block for an hour before a secondary drive chain jumped the sprocket leaving me to peddle home. All in all, a successful day. |
