I have a Staton Honda 35 friction drive on my 1981 Schwinn Cruiser 5 and it works flawlessly (about 600 miles in the last four months). I ride on paved, dry roads here by the beach and with the smallest drive I have decent low end torque and a top speed of 22 mph. In the last 60 days I've been able to ride two Whizzers, a Chinese two stroke and a four stroke Grubee Skyhawk and mine is much a smoother ride. It doesn't have the "soul" of having a engine between your legs but it's a smooth ride, doesn't leak oil and is absolutely dependable.
