BEYOND JUNIOR
For intrepid explorers, the Beyond Junior is a bike built specifically for youngsters. Geometry from its elder siblings scaled-down plus 24-inch wheels, a nimble aluminium frame, and flared bars keep the bike manageable for smaller riders. Being smaller doesn’t mean you need to bring less with you either – the Beyond Junior still has the full range of mounting points as its developed counterparts. Tektro Lyra disc brakes provide adult-sized stopping power, and a 9-speed Microshift Advent drivetrain gives it welly to boot. Even the specifically designed ergonomic levers suit children’s hands.
Relaxed and confident, young riders get big capable tyres, wide flared bars and short stems for control...

¹ Our bike size recommendation generally represents a rough guideline for quickly narrowing down the sizes from which to choose based on the body height. Bike fitting is a complex topic and other measurements and factors have to be accounted for as well. Since no two human bodys are exactly the same it is not possible to give a 100% correct advice for everyone. Therefore BOMBTRACK cannot guarantee for the stated recommendations to be correct for every individual customer. The best way to work out the correct size is to consult a local BOMBTRACK dealer or a professional bike fitter and have them determine the needed size.
