Hi I am new to this. built a Phat seabreeze cruiser with a grubee stage III kit(4-stroke huasheng motor). I want to use my existing freewheel hub/v-brake setup. bolted the 9-hole sproket to the spokes(standard kit setup) there is a little wobble, doesnt look tooooo bad... I want to make a more solid mount. Any suggestions on a freewheel hub for the rear(no coaster brake) or a sprocket mount that bolts to a hub rather than the spokes??? Theres gotta be something that works better.Model #'s? "flip flop hub for a fixie? bmx hubs? complete wheel setup ideas? also the chain tensioner seems like a ghetto setup. anybody tried a gear as a tensioner? or motorcycle/downhill bike chain guides? As it is, my chain keeps pulling off the sprocket and binding, bending teeth! sooo frustrating! I appreciate any ideas and help. Thanks everybody!
