AUTHOR A-Matrix 24D 2026 12.5" Matt Green-Gold/Black/Lime

The Author A-Matrix 24D kids' bike is designed for children aged 8 and over who have already mastered the basics of cycling and want to move on to the feel of a mountain bike. The sporty frame geometry and high-quality components give young riders confidence on longer routes and more technical terrain. The bike is built on a lightweight aluminium frame and is equipped with a suspension fork that helps to handle bumps. Safe stopping is ensured by reliable hydraulic disc brakes.

Lightweight Frame and Sporty Geometry

The Author A-Matrix 24D kids' bike uses a lightweight duralumin frame, which contributes to the bike's low overall weight and makes it easier for children to handle. The sportier frame geometry is designed to replicate the feeling of riding an adult mountain bike. It gives the child a greater degree of control and confidence, allowing them to take on faster rides, longer trips, and more technically demanding off-road sections. This makes the bike suitable for active children who want to develop their riding skills.

Comfort and Control on All Terrains

For a comfortable ride, even off paved roads, the bike is equipped with a ZOOM suspension fork. This helps to absorb shocks and vibrations from bumps, increasing comfort and control. Stability is also enhanced by the 24" × 1.95" KENDA Aptor tyres, which have good grip and make it easier to navigate light terrain. Thanks to this combination, your child can handle bumps with greater confidence, making the ride more fun for them.

Reliable Brakes and Smooth Shifting

Safety while riding is ensured by TEKTRO hydraulic disc brakes. Compared to traditional brakes, they offer higher and more controllable braking power in all weather conditions. The bike is fitted with a Shimano TOURNEY derailleur, which, combined with the Shimano Acera shifter, allows for smooth gear changes across a range of 8 speeds. This makes it easy for your child to adapt their ride to the current terrain, whether they are climbing a hill or riding on the flat.
