The junior Author A-Matrix D 26 is a versatile bike for children 130–150 cm tall. It has 26" wheels and a special lowered aluminium frame, so even a younger, inexperienced rider can easily get through more demanding technical sections, helped by a quality branded RST suspension fork. It also holds its own on tarmac: thanks to the larger wheel diameter it rolls easily and allows longer rides. Another advantage is its effective Tektro disc brakes, which ensure safe slowing in all conditions. Shifting is handled by a quality 8-speed Shimano Acera rear derailleur together with a modern single chainring. A reliable, easy-to-handle bike for any terrain.
