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. With design cues lifted and adapted from our multi-purpose adult HYB hybrid range, the JNR 16" provides the perfect progression from balance bike to pedal bike. A light, triple-butted alloy frame and fork make the bike easy to pedal and balance. The same one-piece bar and stem as our balance model keeps things clean and simple. For those moving up from our balance model, the familiarity reduces cognitive overload, allowing little ones to focus on the new task at hand - pedalling. The first few times starting from a standstill are hard enough without a monster gear that needs to be turned, so JNR 16" uses a single gear set-up that offers the best of both worlds. Easy enough to get spinning but big enough to build up speed as their confidence grows. And once it does, the fast-rolling Vee Speedster tyres will provide plenty of grip, and short-reach brake levers designed for small hands are there to keep things under control
