Rep IV 20

The Rep IV is for the developing rider ready to explore basic trails or ride laps up, down, and around the local park. With similar geometry to a BMX bike, the REP IV looks and feels fast and capable of handling diverse terrain. 20” wheels and a rear handbrake will help boys hone the fundamentals of movement and balance. Because we care about the safety of our youth bikes, all of them are tested by an independent test lab to guarantee the bikes and their components are free of harmful chemicals and meet all the required safety standards. This ensures our kids bikes are as safe to ride as they are fun.
