GT Aggressor Sport 27.5" MTB Black 2019
As at home on the road as it is on tricky off-road trails, this bike offers the lightning-quick handling and reliable performance that you need to enjoy your ride and push yourself to your limits. It is built around a tough yet lightweight triple triangle alloy frame and comes equipped with Shimano 3x8 gearing and mechanical disc brakes. This means you’ve got a gear for all riding situations and reliable braking even in the wet.
Children's bikes are generally measured by wheel size, rather than by frame size. Remember children do grow very quickly and you need to take this into consideration when buying a kids bike, However, if you buy a bike that is simply too big for your child, you will compromise your child's safety, and ultimately discourage your child from cycling.

Which Size Bike Do I Require?
Adults bikes and those for 10/11 years and over, are generally measured by frame size. This is normally the measurement between the centre of the bottom bracket to the top of the seat tube.
