Kids aren't daft, and there comes a time when they'll want a bike as good as mum and dad's. With the Acid 240 Hybrid Rookie SLX, now they can. It features the same Bosch Active drive unit and battery as many of our adult hybrids, so your young rider has the power boost they need to ride further, faster and longer – good news for family outings. The Suntour air fork is easily adjustable to suit smaller, lighter riders – we even used a thinner handlebar and grips for better comfort and control with small hands. Shimano's 10-speed gears are super reliable and offer a great range, and powerful hydraulic disc brakes safely rein in any excess enthusiasm. It's good to go.
Frame description It's fair to say that Bosch didn't have perfectly proportioned kids' bikes in mind when they designed their world-beating drive systems, but that hasn't prevented us from neatly integrating it into the Acid 240 Hybrid Rookie's frame. Using the same design and construction techniques as our adult hybrid mtbs, we've built a junior hybrid that's both fun to ride and safe as well. Internal cable routing significantly reduces maintenance, and we even included mounts for a CUBE kickstand.
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.
