Specialized Riprock Coaster 16 Kids Bike 2019
Designed to shred, the Specialized Riprock Coaster 16 Kids Bike features a premium A1 aluminium frameset that's both lightweight and durable to provide maximum efficiency and fun out on the trails. Its geometry provides a huge standover height, allowing your child's feet to safely touch the ground for a confidence inspiring ride. The bike is also very aesthetically pleasing thanks to its metallic paintwork that sparkles in the sunlight.
Simplicity is key to the design and without gears to worry about your little one can focus on their balance and control, fast-tracking their off-road skills hugely. The 2.3" wide Rhythm Lite tyres don't just look the part, their width offers high levels of grip, comfort and stability, ideal for rougher terrain. Featuring a rear steel coaster brake, safe stopping and big skids are made simple, for a smile-inducing ride every time.
Be sure to carefully consider the size of any bike being purchased for a child, so that it fits perfectly and is ready to go, straight out the box. A bike bought big and to be grown into will be awkward, uncomfortable and perhaps even dangerous if they don't have adequate control. Check out the size guides and age range suggestions so that the bike meets your needs.
Features
- 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 touch the ground for a confidence inspiring ride.
- 16x2.3" Specialized Rhythm Lite tyres provide high levels of grip, comfort and traction.
- A steel coaster brake is a reliable, easy to use brake perfect for safe stops and big skids
