Ready for real riding.
For young riders who want to take on forest and gravel trails.
Author A-Matrix 26D is a junior mountain bike built for kids who already have some experience and want a bike that takes them further – into off-road terrain, forest trails and fun gravel paths.
A lightweight aluminum frame, combined with a suspension fork and a wide gear range, delivers confidence, control and the freedom to explore new routes without limits.
The 26" wheels provide stability and smoother rollover over uneven surfaces, while the sport-oriented geometry supports a confident riding position and precise handling.
The A-Matrix 26D is the perfect step toward “adult” riding – still playful, but fully capable of handling more demanding terrain and longer rides.
Suitable for riders 130–150 cm tall who want to ride actively, develop their skills and rely on a bike that performs beyond paved roads.
Technical specifications for control and off-road riding
Suitable for riders 130–150 cm – ideal sizing for junior riders
Lightweight aluminum frame – low weight, strength and durability
ZOOM suspension fork – improved comfort and control on rough terrain
SHIMANO 8-speed drivetrain (11–40) – wide gear range for climbs and faster sections
KENDA Aptor 26" x 1.95" tires – reliable grip and confidence on gravel and forest trails
The Author A-Matrix 26D gives young riders the freedom to go further, try more and progress to the next level. A natural bridge between junior and adult cycling – with confidence, control and the joy of riding off-road.
