Re: Different throttle?
I do the thumb shifter thing on mine... If you want to keep your mountain bike gears it wouldn't be much help, but if you were willing to sacrifice on of the shifters they work great. You need to take it apart and file down the stops so that it just moves freely from left to right. I bought one of those cable stops and use it on the end of the cable after I slipped it through the shifter control.
I have a three speed shifter I'm going to use if I build another one for sure. I hate those kit throttles.
