  • Traction, control, confidence, and fun—the Riprock 20 Coaster is the perfect bike for your kid to start hitting the trails with. And with the simple coaster brake design, safety and fun are no longer mutually exclusive.

    While there are many notable features that make the Riprock awesome, it's the 2.3-inch tires that provide the high degree of shred-ability—delivering exceptional traction, control, and confidence for riding rough, off-road sections and city streets alike. And when you combine the big tires with sturdy 20-inch wheels, an easy-to-use coaster brake that all but eliminates the threat of the dreaded endo, and a single-speed setup, you have the perfect mountain bike to get your little Ripper out on the trail.

    • 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.
    • Steel coaster brake is a reliable, easy to use brake perfect for safe stops and awesome skids.
    • 20x2.3" Rhythm Lite tires deliver tons of traction, comfort, stability, and fun over all types of terrain.

  • All bikes purchased from iRIDE will have been pre-assembled by our mechanics and test ridden. You will also receive a multi point checklist of all the safety checks and bike build elements we work through to ensure you bike is correctly assembled, and then tested so that it runs as it should. Bikes being sent to a customer who is unable to collect it from iRIDE, will have it boxed, wheels, saddle and bars generally off and re-packaged.

    The delivery of bikes will be organized once a freight fee can be determined based on weight and delivery location.

    Assembly should take no longer than 10-20 minutes. It is recommended that a skilled mechanic assemble, or check the bike. If possible your local bike shop is likely best placed to do this from a safety perspective to ensure all is as it should be. If a rider is having any issues we can hook up an online video chat, or talk over the phone. If this service is required email us at workshop@iride.net.nz to organise a time that suits all parties.
