When designing a bike for young riders, every detail counts. The Acid 240 Hybrid Rookie SLX is equipped with Magura MT Thirty hydraulic disc brakes that not only provide strong stopping power but also feature adjustable levers tailored for smaller hands. A 19mm-diameter handlebar and adjustable air suspension fork enhance control and comfort. The remote dropper post boosts confidence, while the 2.35in Schwalbe Hans Dampf tyres offer reliable grip for skill development. Powered by Bosch’s lightweight SX drive and 400Wh battery, paired with smooth Shimano 1x11 Cues gearing, this bike delivers pedal assistance up to 20km/h for enjoyable family rides.
The Acid 240 Hybrid Rookie’s frame showcases the same meticulous engineering found in our adult mountain bikes, featuring Advanced Internal Cable Routing, a Boost rear axle, and a UDH gear hanger. Its lightweight Bosch SX motor and integrated 400Wh battery deliver up to 55Nm of pedal assist at speeds up to 20km/h, with seamless compatibility for the optional 250Wh PowerMore range extender. Designed to accommodate a dropper seatpost and compatible with SIC 2.0 for easy luggage carrier installation, this bike also includes a kickstand to ensure convenient parking for young riders.
