Mountain Bike

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 Frog MBR 69 is the smaller of Frogs two 26″ wheel kids mountain bikes, designed for children with a minimum inside leg measurement of 69cm.

This is a lightweight mountain bike, with a good range of gears and grippy tyres for tackling those challenging off road trails.

Over the years Frog have been constantly tweaking these bikes to improve the ride – improving things like the tyres and the suspension to better serve their young riders.

This is the attention what you get with a brand that does nothing  but design and build kids bikes.

Frog’s experience in building kids bikes shows as they are offering two 26″ wheel mountain bikes, as kids aren’t all the same size!  The Frog MTB 72  is the larger of the two bikes, suited for those older kids who have an inside leg of 72cm.

Frog Bikes have designed a lightweight frame specifically for junior riders, to increase stability whilst improving control, and the frame comes with a 5-year warranty.

The Tektro junior specific hydraulic disc brakes make it easy for smaller hands to brake whilst remaining control of the bike.

All the Frog mountain bikes come with junior specific air suspension forks, complete with lockout and damping control, to enable optimal performance for lower weight riders,  with 100mm of travel on the two 26″ wheel bikes.

Our 10 year old reviewed the Frog 69 MTB over the summer of 2018, so can you find out exactly what we thought of the early iteration of the smaller version of this bike.

The Cub-Scout 26” takes inspiration from Nukeproof’s award-winning Scout adult hardtail range.

The Cub-Scout 26” has been designed as a proper mini-hardtail mountain bike aimed at children 10 years old and above.

The bike features 8-speed gears and weighs in at 12kg. The

X-Fusion RC32 Air Suspension forks and Clarkes Clout Kids Specific Hydraulic Disc Brakes are just two features of this bike, which has been designed to allow children to learn, progress and gain confidence on the trails.

Add in a pair of 2.5” Maxxis Minion DHF tyres to give grip and a smooth ride, and you’re probably going to be struggling to keep up as your offspring heads off in front of you!
