Default Re: Someone explain please the difference b/w a gear reduction box and a shift kit!

Down and dirty answer. Shift kit utilizes the bicycles gears , so it has a free wheeling "pedal" or chain ring so the motor can drive the chain ring without chopping your feet off, a gear box is needed for a single speed setup to get the motor operating in it's specified RPM range WITHOUT using the bicycles gear shifter. Hope that helped.
