We are considering buying a Rad Runner Plus & Rad Rover. I was wondering would bar ends on the handle bars work with a throttle? On my other bikes I like the different hand positions
They COULD work, but you would probably end up changing grips. The stock grips would be pretty tricky to cut down. If you are fond of multiple hand positions, consider an after-market bar set. Jones, Surly and Origin8 are easily available. The Surly Moloko has numerous hand positions once they are properly installed.
