Specialized Hotrock 20” 6-Speed Kids Bike 2017
Packed full of features that are bound to provide a full and rich riding experience for your little rider, the Specialized Hotrock 20” 6-Speed Kids Bike 2017 is the ideal choice for any child who wants to get out and explore. Everything from the A1 Premium Aluminium frame that’s built for years of abuse, right up to the SR Suntour front fork with 40mm of terrain-absorbing comfort - this is the one they’ll remember.
6 gears is the perfect introduction to the world of speed, allowing them to understand the basic principles of how drivetrains work. With a 36T chainring, it doesn’t pose too much of a threat for little legs, either, and with a 14-28T cassette gives enough gears to get up those testing climbs.
V-brakes are also a welcomed addition to the bike, giving them all the stopping power they need on rough, woodland tracks. They brakes are easy to maintain, too - so as they learn and grow in confidence, they can start to maintain their own bike.
A Specialized Kids’ saddle with 7mm rails and a bumper ensure there’s no bruised behinds when taking on trails, and BMX style pedals come as standard, so as soon as they set their eyes on it, they can get out there and explore.
Features
- Tough, light, and durable, the A1 Premium aluminium frame is built to stand up to years of tough riding.
- SR Suntour suspension fork offers 40mm of coil-sprung travel that smooths out bumpy, rough terrain.
