Okay, I've seen people put shift kits on there multiple geared bikes but I just can't understand how exactly they can maintain them. I have a single gear so I have a sprocket going directly to the wheel but I've burned up three sets of bearings and one entire hub and I don't see how the wheel bearings can hold up to all that friction and heat. I have a coaster huffy so I don't know if that has to do with anything since most geared bicycles are free wheel but I just can't understand how someone can get up to 45 MPH and not destroy their rim.
Do free wheel bearings not take alot of damage at higher speeds only coasters, is there a custom rim you purchase that can withstand the speed and torque, I'm so confused when it comes to it because I want to build a shift kit bike but I don't want to sink 400-600 dollars and destroy the bearings after an hour of riding.
