We've done all the work on this bike to produce something that sticks to an important rule of cycling - it's totally fun. With lots of great features it's easy to ride, complete with increased stability and responsiveness so that your child will enjoy their adventures. You can expect a coaster brake for strong, simple stopping power, wide 12 x 2.3 tires that offer that stability we mentioned and of course tough and durable components that'll survive years of kid abuse.

Designed around our Premium A1 Aluminium frame, the Riprock Coaster 12 is lightweight with the durability to survive the abuse that's to be expected. By using our unique geometry the Riprock features a very low standover height, making it easy for your kids to mount/dismount and grow with the bike.

12x2.3" Rhythm Lite tires deliver tons of traction, comfort, stability, and fun over all types of terrain.

  • The premium A1 aluminum 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.
  • 12x2.3" Rhythm Lite tires deliver tons of traction, comfort, stability, and fun over all types of terrain.
  • Steel coaster brake is a reliable, easy to use brake perfect for safe stops and awesome skids.
