Cube Green Cube Acid 240 bikes 2025

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.
A mountain bike for young riders complete with a suspension fork? You bet. The Acid 240 takes all we know about building safe-handling, durable mountain bikes and re-packages it for the junior cyclist in your family. With a wide gear range, powerful brakes and the extra comfort and control of a suspension fork, they won't want to put it down...
