Wider crankset info
Newbie here to bicycles but a 30 Master Mechanic. I've got a Schwinn Beach cruiser that I'm modifying because I'm 6'4 260lbs and these bikes are not made for us big guys. I'm picking up a set of crank brothers Step 2 large pedals and am going to convert my single crank to a 3 piece but want something wider than stock but not as wide as motorized cransets. Also want the crank arms to be offset to keep my size 14 feet away from chain cover. 68mm bottom bracket
Any help would be appreciated.
