i have a grubee skyhawk gt5 on a beach cruiser and i have on my own figured out many of the standard issues ie. needing all new bolts nuts and washers, strapping the exhaust, using a heavy duty chain and heavy duty rear wheel. however i am tired of finding this stuff out on my own and really would like to be proactive rather than reactive. so if anyone has anything they feel i might need to know what so ever i sure would appreciate it thanks.
