Red’n’green’n’black

Light, strong, simple, versatile... and perfectly proportioned for a keen young rider to get the best from it. That's the Reaction 240 SL, our no-compromise junior hardtail built with aspiring racers in mind. Featuring a heat-treated 6061 aluminium frame and matching lightweight aluminium rigid fork, our design team took a minimalist approach to build the lightest, most reliable and most capable kid's mountain bike they could imagine. Mechanical tube forming allowed our engineers to tailor tube shapes for the best combination of strength and weight, whilst a low top tube - and geometry tailored to provide a blend of confidence-inspiring stability and fun-enhancing agility - work together to make the Reaction 240 SL both fun and safe. Read more... The powerful V-brakes are easy to control thanks to levers designed for small hands, and a power modulator on the front brake reduces the risk of an unscheduled over-the-bars dismount caused by over-enthusiastic braking. Shimano's slick-shifting SLX 11-speed gears cover an enormous range, putting even the steepest of climbs within reach of a determined youngster. And big-volume, super lightweight folding Schwalbe tyres offer loads of grip and comfort for confidence-inspiring handling in the dirt, whilst wheels with a reduced spoke count save even more weight. Your child will love it and you will too, safe in the knowledge that we've sweated all the details.

CUBE REACTION 240 SL

The CUBE Reaction trail bike series offers a mix of performance and value, with models praised for their acceleration, climbing efficiency, and component quality. However, some reviews note a harsh ride on descents, limited mud clearance, and tyres that struggle in wet conditions. The bike is often compared to the Specialized Epic Hardtail and Canyon Exceed CF SL 7.0 for its trail capabilities.
