The Rockrider ST920 kids mountain bike is a great route into the world of mountain biking for junior riders, with a lightweight aluminium frame and suspension fork. Its specification includes a Shimano Altus rear derailleur and thumb shifter for changing through the 9 speeds and comes fitted with an 11-36 cassette paired with a 36…

The BTwin 20 Riverside 120 is Decathlon’s entry level 20″ wheel geared bike, which offers great value for money.

Weighing in at a very respectable 11.2kg, the bike is considerably lighter than many other bikes in this price range.

The 6 gears are simple to operate using a Microshift twister to help with hill climbing.

The bike is supplied with a front and rear battery operated LED light, which is a great touch.

This bike will be suitable for riding on roads and leisure trails that involve some hills.

If your child isn’t quite ready for gears, or is riding on flat terrain only, then there’s a single speed version of this bike – the Riverside 100 – which is slightly cheaper.

The BTwin Rockrider ST900 model is a generously equipped kids mountain bike with a new lightweight aluminium frame design paired with a Suntour XCT suspension fork with 50mm of travel to help cushion the lumps and bumps of forays through woods and forests.

Aimed at riders between the ages of 9 and 12, the ST900 takes the game a step further than its ST500 sibling, with the fitment of mechanical disc brakes front and rear for added stopping power, plus an 8 speed gearing system with a single chainring at the front for simplicity and operated with a Shimano Altus thumbshifter and derailleur.

The Rockrider ST900 also compares favourably with bikes carrying a higher price tag in terms of weight, coming in at 12kg including pedals.

BTwin are the in-house brand of kids bikes at Decathlon, and they come in a range of prices and specifications.

The Rockrider ST500 24 inch is one of their steel framed entry level mountain bikes, suited for gentle riding on or off road.

The gearing is 18 speed (which can be more confusing than 6 or 7 gears due to needing to use both hands to change gear).

The v-brakes should be plenty good enough for gentle off roading in fair weather, and the bike has front coil suspension to smooth out some of the bumps on the trail.

The front wheel is quick release, to help with transporting and maintenance, and the tyres are designed for gentle off roading.

Given it’s such a cheap MTB, the BTwin Rockrider offers a really good value entry level mountain bike, that should provide plenty of scope for fun during summer riding.

BTwin (who are an in-house brand of Decathlon) are going through a makeover of their kids bicycle range, with some very good value bikes arriving in stock.

The BTwin Rockrider ST500 is a 26″ wheel kids mountain bike aimed at riders around 9-12 years of age and between 135 and 150cm tall.

Featuring an aluminium frame and suspension fork at the front, the ST500 comes with a single chainring and 7 speed gearing using a thumbshifter to minimise complications (kids mountain bikes at this cheap a price usually have a lot more gears that are confusing to use and harder to maintain).

The bike is equipped with v-brakes and a set of tyres suitable for gentle off roading.

They’ve got a great video on the Decathlon website showing the types of fun you can have on these bikes.

With a price of £249.99 the BTwin Rockrider ST500 really does represent value for money and would be a great way to get a child off road and muddy!

The BTwin Riverside 900 is a lightweight aluminium bike at a great price point.

For ages Decathlon’s own brand BTwin kids bikes have been much heavier steel affairs, so we’re really pleased to see that they’re upgrading to aluminium for the frame, fork and chainset. Not only is this lighter (and therefore easier to ride) it’s also much less likely to rust.

The Btwin Riverside 900 with 20″ wheels is a great hybrid bike for ages 6 – 9 years old with a height of 120 – 135cm.

It is available in a grey/green colour and is a lightweight bike that will be great for riding both on tarmac and on the trails.

The specification on the 900 range of BTwin kids bikes includes all the things we’d expect to see at a much higher price.  This means you get things such as easy to use gears, child friendly brakes and shorter cranks for easier pedalling.
