Greetings from a fellow Michigander, RR. Welcome to the club!
I once had a Huffy Cranbrook Cruiser with that motor, and it did alright until the chain tensioner ate the tire. Keep an eye on that thing, and mount it to two points on the frame to prevent wobble and twist...
We ended up moving the motor over to a schwinn chopper later on for a different feel, but the frame never did crack on that Huffy. Be sure to check for good welds, especially in the dropout area. These things considered, they can be nice bikes with a little prep work and upkeep.
