I installed this onto my 1997 Jamis Aragon hybrid bike with a 49cc Huasheng 4 stroke and this particular kit hasn't failed me yet!
I've had this kit for a while (almost a year) and can say that the 1" roller provides plenty of torque for those steep San Francisco hills and on flat roads, still goes around 20-25 mph.
