I have a early 60's Schwinn Knucklehead Boulevard Cruiser that I'm thinking about putting an engine on . A few years back I put in a Shimano 7 speed hub as I live in the mountains and every direction seems to be uphill.
If I was to install a 2 or 4 stroke engine of 1.5-2 HP,would this hub be strong enough to take the speed and torque of the engine? I understand the force a human leg can place on the crank shaft of the peddles but would hate to trash this outstanding hub.
I'm also open to any ideas as to what engine to use on this bike. It's a tank to be sure.
Thank you.
