Dear Fellow Gearheads,
My second build is a 66cc Hyper Cruiser with 46 miles on the odo. I installed a high quality rim brake on the front to assist the coaster brakes. After noticing that the rear hub was warm to the touch, I also noticed that rotating the rear wheel with the clutch disengaged caused the pedals to rotate. I knew that this meant that the rear wheel cone bearings were a tad tight. I removed the wheel from both chains and loosened the bearings until there was a little felt play. I then retightened them until the pedal sprocket started catching again and then loosened a quarter turn before reinstalling the wheel and applying torque to the outer retaining nut. Now rotating the rear wheel with the clutch disengaged does not rotate the pedals via the chain. However, the rear hub is still warm to the touch. After 15 minutes or so, the hub cooled back to ambient temperature. I am still breaking in the motor, did not exceed 15mph and traveled about 1-2 miles. All of the bearings were cleaned and repacked with Park grease by the local bike shop before the motor was installed. When properly adjusted, do these rear hubs heat up at all? I realize that cone bearings are not the best design, and that these cruiser bikes are pretty inexpensive. Thank you in advance for any adjustment info
