Cube Acid 240 Allroad Junior Mountain Bike 2021 - Green

We think it makes little sense if parents first have to make the bike they have just bought roadworthy for their kids. With the Acid 240 Allroad, we therefore offer a model that can do everything - and has it all. In other words, various accessories that you often need in everyday life: mudguards for bad weather (and clean clothes), an LED light system for "seeing and being seen", a power modulator on the front wheel that regulates excessive or abrupt braking so that the kids do not make an involuntary take-off over the handlebars, and a side stand so that you no longer have to lean the bike against trees, park benches or house walls.

As a performance finish, we have installed a Suntour suspension fork, skilfully erased the unevenness of the ground on rough ground, and a wide 7-speed gearshift, which changes easily and smoothly from gear to gear. Excellent!


  • Lightweight alloy frame
  • SR Suntour SF15, 60mm
  • 1x7 drivetrain

Ready to ride

Every bike from Start Fitness is fully checked & assembled before despatch and will arrive, almost, ready to ride. Each bike is assembled by one of our CyTech accredited mechanics and then packed into one of our custom boxes. Minimal assembly, with basic tools, is required before you can ride. Assembly tools are not usually included. Please note: Some bikes are not supplied with pedals. Manufacturers don’t know if you want flat or clipless pedals, rather than send the bike with the wrong type, they leave the choice for you to make.   This process has a lead time of between 5-7 working days Unfortunately during peak times this may be slightly delayed. We will however, aim to despatch your bike as quickly as possible.  

Making sure you are home

Once fully checked and boxed, we will contact you to book a delivery date. Our bikes are despatched on a next working day service (excludes weekends & bank holidays) for UK mainland orders, or a two day service to Northern Ireland and outlying Scottish areas. European bike deliveries usually take approximately one week.  

Taking Delivery

Any mechanical or cosmetic issues need to be reported to us within one week of the delivery date. If you do not plan on using the bike straight away, we advise that you remove it from the box and check it over ASAP as we cannot be responsible for any reported issues (other than standard warranty issues) later than one week from the date that the bicycle was delivered.  

First Check-Over

After a few weeks of riding (depending on riding style and conditions), a new bike will need a check-over to make final adjustments and to re-check all nuts and bolts. This is necessary as the bike goes through a ‘bedding in’ phase after which, final adjustment may be necessary. We recommend that this is carried out by a CyTech qualified mechanic. It is important to have these checks carried out to prevent any avoidable problems which may not be covered by warranty and to ensure the smooth running of the bicycle.   We can carry out the first check-over free of charge, at our Newcastle store (NE16JE). If you’ve had the bike delivered, it will be your responsibility to get the bicycle to and from our store for this work to be carried out. This complimentary check-over does not include any labour to replace worn parts or to fit new accessories.   All bikes must be booked in for the first service & must be clean or a £15 cleaning charge will be payable. You can book this by calling 0191 261 4191. Proof of purchase will need to be presented when the bicycle is dropped off for the first check-over.  

Bike Servicing

Bicycles need to be serviced regularly, as a guideline we would advise on at least one full service per year and/or a standard service twice a year. If the bike is used regularly in adverse conditions, more regular servicing may be required.
