Cube Acid 260 Disc 2025 26" Galactic/Cyan Kids Bike

Available with Cube in the sizes shown above. Expect delivery within 8-9 working days of placing an order.

No half-measures, even for our junior bikes. That’s why the Acid 260 uses the same mechanically formed, double-butted, heat-treated 6061 aluminium tubes as our adult range.

Combined with our Agile Ride Geometry, it makes for a frame that’ll allow your child’s skills to develop as their confidence grows. And there’s a replaceable gear hanger, too, so that a crash needn’t be the end of the world.

Keen young riders will benefit from a bike that fits their needs – literally. The Acid 260 is every inch a trail-capable mountain bike, scaled down to perfectly fit pint-sized riders. With 80mm of bump-swallowing travel, the Suntour suspension fork improves comfort and control.

Shimano’s smooth and reliable 16-speed gears have the range to tackle any climb, and powerful disc brakes provide loads of stopping power. It’s everything they need for trail adventures.
