CUBE Crankset, 32T, 152mm, with Chainguard, Token BB

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 new junior hardtail. Featuring a heat-treated 6061 aluminium frame and matching aluminium fork, our design team took a minimalist approach to build the lightest, most reliable and capable kid's mountain bike they could imagine. The powerful V-Brakes are easy to control, thanks to brake levers designed to accommodate a child's shorter reach - and a power modulator on the front to help reduce the chance of an unscheduled over-the-bars incident. SRAM's slick-shifting NX 11 speed gears cover a huge 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.

CUBE REACTION 240 SL

The CUBE Reaction trail bike series offers a mix of agility, stiffness, and value, with models praised for their lightweight frames and quality components like Shimano transmissions. However, some builds suffer from basic forks, heavy wheels, and tyres lacking in wet-weather grip. The bikes are noted for their lively ride quality but can feel cramped and may require upgrades for optimal performance.
