Boardman JNR 24" 2025 - Junior Bike
The Boardman JNR 24" kids bike shares many of the same attributes as the JNR 20". A lightweight alloy frame and fork, V-brakes with short-reach levers for smaller hands, a junior-specific saddle and fast-rolling tyres are all there to inspire confidence and make the cycling experience engaging and enjoyable.
Key features:
- Lighhtweight Triple butted, smooth weld aluminium frame
- Smooth weld aluminium lowers with Chromo Steerer forks
- Tektro hydraulic disc brakes offer all weather stopping power
- Weighs just 9.6kg
- Size: 24” wheel
- Colours: Blue
- The Boardman JNR 24” is available with 0% APR finance
However, the 24" version builds on these features by adding a nine-speed groupset and wider ratio cassette, which opens up even more exploration opportunities. Rack and mudguard mounts on the frame mean the 24" is incredibly versatile; they can load up for those longer family rides or stop the spray and soggy bottom when the weather turns wet.
Forwards, Faster, Further - three words that encapsulate the Boardman ethos and influence every product Boardman have made. These three words represent the vast spectrum of our rider's cycling ambitions and goals, which Boardman want to support them in achieving, however big or small they are.
When it comes to riding bikes, kids are constantly pushing forwards, riding faster and exploring further. So when designing our first full range of junior bikes, Boardman have put Forwards, Faster, Further on each bike to keep the childlike joy and freedom of pushing the boundaries on a bike at the front of our minds.
The JNR range comprises six models, each with the goal of getting kids outside, cycling and exploring whilst supporting their developmental progression. From those first freewheeling forward movements on the 12" balance bike to the pride of mastering pedalling and going faster than before on the 20", to a family adventure venturing further on the 26", we've carefully considered every aspect of each bike's fit and function. Function hasn't come at the expense of form though, hidden welds and premium metallic paint finishes help the bikes to look as good as they ride.
Our goal is to ensure that the simple act (after some practice) of riding a Boardman JNR is as fun and empowering as possible.
