The Cube Reaction 200 Pro is a lightweight and capable 20-inch kids' mountain bike designed for young riders who are ready to explore trails, bike parks, and everyday adventures. Inspired by Cube’s adult mountain bike range, it combines a durable aluminium frame, reliable components, and child-specific geometry to provide confidence, comfort, and control on every ride.

Built with a lightweight Aluminium Lite 6061 frame, the Reaction 200 Pro is easy to handle while remaining strong enough for active riding. The carefully designed geometry ensures stable handling and a comfortable riding position, helping young cyclists build skills both on and off the trail.

Equipped with a Shimano 9-speed drivetrain, the bike offers a wide gear range for tackling climbs and faster sections with ease. Powerful Shimano hydraulic disc brakes provide reliable stopping power in all weather conditions, while the lightweight aluminium fork keeps weight low and handling responsive. Schwalbe Smart Sam tyres deliver excellent grip and confidence on pavement, gravel, and forest trails alike.

This children's bike is a OneSize model suitable for kids up to the following maximum measurements:

• Height: 111cm -124 cm
• Inside leg: 49 - 57 cm
