Lightweight 24 Inch Kids Mountain Bike with Disc Brakes and Suspension Fork

The 2026 Cube Acid 240 Disc Kids Mountain Bike is a high-quality 24 inch kids mountain bike built for young riders who want confidence, control and real off-road capability. Designed with the same attention to detail as Cube’s adult bikes, the Acid 240 Disc combines a lightweight aluminium frame, powerful hydraulic disc brakes and a suspension fork to create a capable and fun children’s mountain bike for trails, family rides and everyday adventures.

Built for aspiring young mountain bikers, this kids MTB offers the right balance of low weight, durability and easy handling. Whether riding forest tracks, local trails or rougher paths, the Cube Acid 240 Disc is designed to help children ride further, climb more confidently and enjoy every ride.

  • Lightweight, durable 6061 aluminium frame
  • Disc brake mounts for reliable stopping power
  • Bottle cage mount for longer rides
  • Rack mounts for added practicality
  • Replaceable gear hanger for easier, lower-cost repairs

Strong, Lightweight Aluminium Frame

The Cube Acid 240 Disc frame is made from heat-treated 6061 aluminium, giving it the strength and durability of a full-size mountain bike while keeping the proportions and weight suitable for younger riders. This makes it an excellent choice for children who need a bike that feels responsive, manageable and confidence-inspiring.


This thoughtful design gives parents extra peace of mind, while giving young riders a bike that is ready for regular use on mixed terrain.


Powerful Hydraulic Disc Brakes for Safe Control

One of the standout features of the Cube Acid 240 Disc Kids Mountain Bike is its hydraulic disc brakes. Offering dependable braking performance in all weather conditions, these brakes are easy to control and provide strong stopping power for young riders building their skills on trails and descents.

The brake levers are also designed for smaller hands, making them easier and more comfortable for children to use with confidence.


Suspension Fork for Comfort and Trail Control

The Suntour suspension fork helps smooth out bumps, roots and rough paths, improving both comfort and control. For children riding off-road or exploring uneven ground, front suspension makes a noticeable difference by helping the bike stay composed and easier to manage.

This makes the Cube Acid 240 Disc a great option for young riders who want a kids mountain bike with suspension that feels capable on more adventurous rides.


Wide-Range 8-Speed Gears for Hills and Trails

The easy-to-use 8-speed gearing gives young riders the range they need for climbing hills, riding flatter sections efficiently and handling changing terrain. Whether riding on trails or family bike rides, the wide gear range helps children stay comfortable and in control.


Designed Specifically for Young Riders

Every part of the Cube Acid 240 Disc is designed with younger riders in mind. From the saddle and grips to the handlebars and brake levers, the bike is built to fit children properly for a safer, more comfortable ride.

This attention to fit and ergonomics makes it an excellent kids bike for off-road riding, helping children build confidence while enjoying a bike that feels just right.


The Cube Acid 240 Disc 24 inch kids mountain bike is ideal for:

  • Young riders who want a real kids mountain bike for trails and family rides
