The Haro Little Kids Shredder 12 Sidewalk Bike There's nothing quite like the feeling of riding your first pedal bike and the Haro Shredder 12 is where it all starts. Transitioning from a Haro PreWheelz balance bike to the Shredder 12 is made easy with features like the low profile light weight aluminum frame and rear coaster brake which provide confidence and ease of control to riders new to pedal bikes. The alloy rim wheels and 1 1/8" threadless headset are durable and built to stand the test of time. The Shredder 12 also includes a full pad set and heavy duty training wheels for those who may need an additional stepping stone making the transition to a pedal bike.
