              Renowned frame geometry and fit

              The Beinn 20 Large’s super light weight, matched with our years of experience in child-specific frame geometry and fit, make riding and manoeuvering as effortless and enjoyable as possible.

              Islabikes' frame geometry and components guarantee a perfect fit and flawless control
              20 inch wheels smooth out the surface you are riding on

              Rolling with confidence

              Islabikes are designed to accommodate the largest diameter wheels possible without compromising the perfect riding position. Why is this important? Bigger wheels “smooth out” the surface you are riding on and are also naturally more stable than smaller ones. This extra stability substantially improves young rider confidence.

              Are you pedalling comfortably?

              The horizontal distance between the pedals (known as the Q-factor) is an important yet often overlooked factor on children’s bikes. Wider Q-factors often result in uncomfortable pedalling and side-to-side wobbles. As the result of our careful frame design and component developments the Beinn 20 Large has an optimized, ultra-narrow Q-factor of just 135mm, ensuring feet are positioned closer together for a more natural pedalling action.

              Exclusively designed grips handlebars and brakes for kids hands

              Perfect control for small hands

              Everything on our Beinn 20 Large handlebars is designed exclusively to give smaller hands full-size control. From our unique super-light brake levers to downsized bars and grips, nothing is too much trouble to guarantee safety and comfort.

              Easy to use low gearing for conquering climbs

              Many kid’s bikes are painfully over-geared, but our single 32 tooth chainring with 11-34 tooth rear cassette provides a wide range of gears to tackle any gradient.

              Light action, SRAM Grip Shift shifters take care of changing gear. They are simple and intuitive in use, allowing the rider to keep their hands on the handlebars, maintaining control whilst changing gear.

              Versatility designed in

              Whether riding on the road, cycle touring, school runs or even off-road explorations, the Beinn has versatility designed in. Featuring mounts for our custom luggage racks and mudguards, there are a whole host of unique Islabikes accessories that can be added to ensure the Beinn grows with the rider’s ambitions.
