the Beyond Junior

a diminutive bike for big adventures.

"Relaxed and confident, young riders get big capable tyres, wide flared bars and short stems for control..."

Introducing the Beyond Junior

Built for tearaways, the Beyond Junior ensures young riders aren’t left behind. Using the same geometry as its larger siblings, 24-inch wheels, a light aluminium frame, and flared bars keep things manageable for smaller riders. Teaching self-sufficiency, all the mounting points you’d expect are present, allowing its rider to carry as much or as little as they want. With Tektro Lyra disc brakes providing full-sized stopping power, a custom 9-speed Microshift Advent drivetrain includes levers feature a reduced lever reach and spring tension, specifically tailored to little hands.

    * 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.
