CUBE REACTION 200 Pro - 20" Children's Mountain Bike - 2026 - black / blue / red

Bring on the fun. 

Kids are tough. They also like to push their boundaries – and that's why they need a bike that's tough, too. The CUBE Reaction 200 Pro has the light weight and durable, easy-to-use components that will allow a young rider's skills to grow.

There's a full carbon fork with thru axle, for a more comfortable ride. Wide-ranging, smooth-shifting 1x8 gears. Grippy Schwalbe tyres and powerful disc brakes. And handlebars, saddle, cranks and grips are all perfectly proportioned for a growing rider, so they'll be comfortable and in full control. 

Features of CUBE REACTION 200 Pro:

• Aluminium Lite frame
• Carbon fork
• Replaceable derailleur hanger
