Get off stablisers and on a proper kids mountain bike. Specialized have simply downsized their popular adults mountain bike and added a host of child friendly features to make the Specialized Hotrock 24 Street 7 Speed Boys Bike 2017, the ultimate kids bike for racing and on and off road adventures.

Specialized Hotrock 24 Street 7 Speed Boys Bike 2017

The Specialized Hotrock 24 Street 7 Speed Boys Bike 2017 is the perfect bike for youngsters looking to take their first steps in the exciting world of cycling. The 24 inch wheels are a great addition, allowing for a fast and component handling bike. Powerful Die-cast V-brakes work well whatever the weather. A proper little mountain bike, the Hotrock features a single 36 tooth front chainring and a 7-speed Shimano drivetrain, Specialized Nimbus tyres and a comfortable and supportive Specialized Kids saddle.

Comfort, durability and performance are addressed with the A1 Premium Aluminium frame and handling is enhanced with the addition of an alloy straight bladed fork.

The Specialized flat handlebar and alloy stem aid handling and the Specialized Kraton grips improve control. An alloy seat post soaks up the bumps and the strong 32 hole alloy rims are ready for whatever terrain the bike is taken over.

In a dynamic red, white and black colour scheme with eye-catching Specialized graphics, this is sure to be the envy of every school playground.

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.

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.
