Description

The Cube Acid 240 Hybrid Rookie SLX 400X is a 24-inch electric mountain bike built for young riders who are ready to explore real off-road terrain. The Superlite aluminium frame integrates the Bosch CompactTube 400 Wh battery cleanly within the downtube, keeping the centre of gravity low and the overall feel balanced and manageable. It's recommended for riders 124 to 141 cm tall (57–66 cm inseam), with a maximum rider weight of 50 kg.

The Bosch Performance SX motor delivers 55 Nm of torque with smooth, well-measured assistance suited to a young rider, controlled through the Bosch Purion 200 handlebar display — straightforward to read and operate on the move.

Safety is taken seriously: Magura MT Thirty hydraulic disc brakes (160 mm front, 180 mm rear) deliver consistent, powerful stopping even on steep descents. The Suntour Raidon34 2CR air fork (80 mm travel, 15x110 mm thru-axle) smooths out trail chatter and keeps the front wheel planted. A CUBE dropper post with internal routing lets young riders drop the saddle for descents — a rare feature on a kids' bike.

The Shimano Cues 11-speed groupset with a wide-range 11-50T cassette handles everything from grinding up hills to rolling on flatter tracks, and the Rapidfire-Plus shifter stays easy to operate with smaller hands. Tubeless-ready ACID SLX 20 wheels with Schwalbe Hans Dampf 2.35" (Kevlar) tyres round out a clearly trail-focused build. The frame uses adult standards throughout: Boost 148 and a UDH™ derailleur hanger. Claimed weight: 18.2 kg.

Robust and weather-resistant, it faithfully accompanies every outing, whatever the weather.
