This is the bike that all youngsters are going to want – light, strong and equipped with everything they'll need for off-road adventuring with friends and family. Hydraulic disc brakes are powerful and easy to control, with levers specially designed for small hands. The Suntour suspension fork improves comfort and control on rough trails, and the wide-ranging 1x9-speed gears are easy to use and give a range that'll make light work of any hill. Off-road adventures are just a few pedal strokes away...
Frame description Built from the same heat-treated 6061 aluminium tubes as our adult bikes, the Acid 240 Disc's frame is every bit as tough as a full-size mountain bike, but with the right weight and proportions for a child. Disc mounts allow the use of these powerful, safe and easy-to-use brakes. 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.
