Specialized Hotrock 24 21-Speed Girls Mountain Bike 2017
When your budding young rider is ready for some off-roading, the Specialized Hotrock 24 21-Speed Girls Mountain Bike 2017 is the perfect choice. With a durable A1 Premium Aluminium frame, a suspension fork with 50mm of travel, and wide range gearing make the Hotrock 24 21-speed trail-ready for big kids.
For the child between the ages of 9 to 11 and between 1.20 metres to 1.35 metres tall a 24 inch diameter wheel is the perfect choice. This again is faster than smaller wheeled bikes and this size of bike now starts to resemble a small adults bike, with many of the same components and features.
