Re: What is the quietest motorized kit
When I am riding with a stock hua sheng 4 stroke all the people I meet have grins on their faces and I ride around in a town full of greenies. It could be made even quieter with an extension that would angle the outlet directly towards the ground. In fact the current drive train makes as much noise as the motor.
Good luck with your electric bike. Your cost for silence will be way more than a 4 cycle gas and your range wayyyyyy less. The most expensive electric bike that I know of, the optibike, is just about as loud as my bike due to its drivetrain noise btw. The hub motor bikes are the quietest.
