Simplicity can be a virtue. With our Acid 24 SLX Teamline, we looked at what a keen young mountain biker really needed from a bike – low weight, safe handling and reliable components – and stuck to those principles. That's why it features a lightweight alloy fork, light and simple rim brakes, and a wide-ranging 1x9 transmission with a low enough gear to tackle even tough climbs. We even fitted a thinner handlebar and grips, so that small hands have full control on any trail.
Frame description Built from the same heat-treated 6061 aluminium tubes as our adult bikes, the Acid 240's frame is every bit as tough as a full-size mountain bike, but with the right weight and proportions for a child. There's a bottle mount for mid-ride refreshment and rack mounts, too. The handling is designed to be both fun and confidence-inspiring. And, because we know accidents can happen, we made the gear hanger easily replaceable so that a knock or crash needn't result in an expensive repair.
Find your size!
Enter your height and inseam below and click on 'Calculate my frame size' to see which size you need. You measure your inseam as follows:
1. Stand barefoot with your heels against the wall. Place your feet about 6 inches apart.
2. Grab a book and place it between your legs, with the short side of the book against the wall. Press the book up against your crotch, mimicking the idea of a bicycle saddle.
3. Measure the length from the top of the book to the floor, the distance you measure is your inseam.
