Re: Throttle upgrade
I have done both used the brake handle off an old Bmx bike. (currently) and I bought the twist throttle from Napa. The grips from Napa where horrible so I just replaced them with an old set from my Haro Gt. I just wanted to try the Brake handle Throttle and have that just below the Dual brake lever ( best $10.00 I have invested yet) and the clutch on the other side and all is good. And if you want Cruise control use a rubber band. I don't but, to each his own.
Hope it Helps. I am also a proud member of the 20 MPH. club
