Cube Acid 240 SL Kid's Bike

The Cube Acid 240 SL is a lightweight, durable and stylish kid's that's ideal for trail riding over rough terrain and efficient cycling anywhere. It features an aluminium frame with a rigid alloy fork and is equipped with powerful V-Brakes and 1x9-Speed drivetrain with a wide-ranging 11-42T cassette. Suited to climbing steep hills and descending fast trails in all-weather conditions, this bike is a sensational off-road bike for junior MTB enthusiasts.

Stable, Efficient and Enjoyable Off-Road Trail Bike

Designed for ease of use, this reliable model's Prowheel crankset and MicroShift cassette allows your child to pedal up to speed in seconds. When cornering and tackling steep descents, its V-Brakes provide superb stopping power and control. One final highlight is this SL version comes complete with reflectors and a bell, so your young rider will have everything they need to ride confidently in all conditions.

Lightweight, Durable and Easy to Control Hardtail

Simplicity can be a virtue. With the Cube Acid 24 SL, they looked at what a keen young mountain biker really needed from a bike - low weight, safe handling and reliable components - and stuck to those principles. That's why it features a lightweight alloy fork, light and simple rim brakes, and a wide-ranging 1x9 transmission with a low enough gear to tackle even tough climbs. We even fitted a thinner handlebar and grips, so that small hands have full control on any trail.

When you order a bike, one of our trained mechanics will carefully prepare and pack your bike for shipping. Upon delivery, the assembly is simple and all necessary tools and plastic pedals are conveniently included in the box.

Depending on the delivery service and destination, bikes will either be delivered in a large or a small box. Below is a guide as to how your bike will arrive:

  • All bikes for delivery within the UK and Republic of Ireland will be delivered in a large box, except for balance bikes and BMX bikes, which are always delivered in manufacturers boxes.
  • All bikes for delivery within the EU on a standard service will be delivered in a large box. If an express delivery option is chosen, your bike will be packed into a small box. Again, the exception is balance bikes and BMX bikes, which are always delivered in manufacturers boxes.
  • All bikes for worldwide delivery outside the EU will be delivered in small boxes.
