Default Re: Bottom crank jack shaft.

ok might look confusing im not good on cad but i hope it gets the point across
there is the gear cluster which will include a 44 and 36 bolted with a 1/4 in plate for spacing then it will run to a baring on the rear frame on the outside of the two gears will be a old steel bmx hub part weled to a bolt on plate so i can thred the free weel on ie the small circle in the 3 set. the pic is kinda messed up the big gear in the middle should to to top jackshaft gear and the meedem should go to the back rim. and the small free weel to the cranks

there fore i should have no problems with the cranks spining when motor is runing right?
