Specialized Hotrock 20 6 Speed Girls Bike 2017
A lightweight, low-standover frame with child proportioned, easy-to-use controls make the Hotrock 20 perfect for a first multi-speed bike. A 50mm travel suspension fork takes some bite out of the bumps.
When choosing a kids bike there are a number of variables to consider. From a size point of view kids bike sizing is based on wheel size. You want your child to be in control and be able to enjoy the bike to its full potential, so a correctly sized bike is a must.
It is easy to think the child will grow into the bike but a bike to big will be dangerous, difficult to handle and less enjoyable to ride. What type of bike is the next decision.
The 20 inch wheel is when things start to get serious. Ideal for rides as a family and longer time spent in the saddle, these bikes suit kids ranging from 7 to 9 years old.
Features
- 20" A1 Premium Aluminium frame with low standover height plus 40mm-travel fork with preload adjust for all-terrain fun
- Lightweight 32-spoke alloy rims are durable and provide a stable platform for learning
- Specialized Roller tires provide a knobby grip for dirt, but roll easily on pavement
- Shimano Revo 6-speed twist shifters allow easy, safe gear changes without switching hand positions on the bars
- Kid's Body Geometry saddle is durable and comfortable and fits young riders perfectly
