Product Information:

Riding a bike is all about freedom, so no kid should ever have to feel inhibited by where they can and can't ride their bike. With the Riprock 20 Coaster, however, your little one will be able to rip and ride on any terrain that they come across—especially with the easy-to-use coaster brake. You remember how it works from when you were a kid, right? Instead of hand brakes, they use the pedals to slow down. Nice and easy. Even better, this Riprock has wide, 2.8-inch tyres deliver traction, control, and confidence in spades, while the custom suspension fork will absorb all of the rough stuff that comes with riding off-road. And with powerful mechanical disc brakes, sturdy 20-inch wheels, and a low standover that all but guarantees a perfect fit, you can rest assured that the Riprock 20 is the perfect recipe for fun that your family has been looking for.

  • The premium A1 aluminium frame is lightweight and built to withstand the tough use by kids, while the geometry features an ultra-low standover that makes it easy for your little ones to fit on and grow with the bike.
  • 20x2.3" Rhythm Lite tyres deliver tons of traction, comfort, stability, and fun over all types of terrain.
