Cube Acid 240 Disc 24w 2022 - Junior Bike
When our engineers set out to design the Acid 240, they began with the same kind of heat-treated 6061 aluminium tubes that we use in our adult frames. The result is a frame that's every bit as durable as a full-size mountain bike, but with the right weight and proportions for a child. Mechanically formed tubes mean that it's bang up to date in terms of technology, too. The geometry is tailored to the needs of young CUBE riders, so it's stable and easily controllable, with a low top tube to improve confidence and safety. And, because we understand that accidents will happen, we made the derailleur hanger easily replaceable so that a knock or crash needn't result in an expensive repair.
The Acid 240 Disc is the bike that all youngsters will want. Light, strong and equipped with everything they'll need to help them keep up with their friends and family, it's got all the features you'll find on our adult mountain bikes. Hydraulic disc brakes are powerful and easy to control, with levers designed specifically for small hands. The Suntour suspension fork improves comfort and control on rough surfaces, and a wide-ranging 7-speed Shimano transmission gives a huge range of gears for tackling any terrain. From the heat-treated, mechanically formed 6061 aluminium tubes to the child-tailored geometry, our engineering team lavished the same attention to detail and perfectionist approach on this bike as they do on every bike they design. The low top tube improves confidence and safety, while a replaceable gear hanger makes the inevitable mishaps and knocks less costly. And, as you'd expect, the entire bike has passed our stringent in-house safety tests with flying colours. With a bike like this, there's nothing standing in the way of epic off-road adventures for the little mountain bikers in your family...
