    THE ULTIMATE OFF ROAD BIKE IN THE BYK RANGE.

    620MTBD | AGE: 10 – 14 YEARS | HEIGHT: 142.5 – 170 CMS

    Ability Level: Experienced skills and can ride off-road terrain confidently. Seeking performance.

    Taking the next step in performance with race level enhanced geometry, high performance hydraulic disc brakes, double butted alloy frame, disc specific rims, lightweight lockout suspension forks and race inspired Shimano 1 x gearing system with a custom front chain guide.

    The evolution of the ByK Mountain series bikes takes on new challenges and exciting adventures.

    Design:

    Committed to the ultimate off road potential, the 620MTBD is a machine that inspires fun and adventure.

    Like the entire ByK Range, this is not a scaled down adult bike. Every single component has been considered, tested, custom sized and tuned to suit our rider’s profile. Our unique ergonomic riding position and geometry offer a range of riding positions and adjustability unexpected at this size.

    Performance:

    We have weighed every single component, measured to a millimeter the geometry and ergonomics and tested on every trail we could find. Our long list of premium components is outstanding.

    Taking the next step in performance with race level enhanced geometry, high performance hydraulic disc brakes, double butted alloy frame, disc specific rims, lightweight lockout suspension forks and race inspired Shimano 1 x gearing system with a custom front chain guide.

    We have strengthened our wheels, used extra grip lightweight tyres, an ergonomic saddle and customized our unique V bars for off-road fun.

    Everything has been considered to make this bike perform in a class of its own. The ByK 620MTBD re-defines MTB fun for kids.

    Safety:

    From our responsive handling to increased safety at speed, the ByK MTBD Kids Mountain Bike range sets new standards in safety. The innovative frame improves balance and control to help each rider operate at the safest level possible.

    To make a children’s bike safe, the rider needs to be able to brake efficiently and confidently. The custom-sized V-Brakes we have used are calibrated for age, ability and ergonomic fit. And they are made of non-flexing, strong and light alloy. Our light weight alloy rims ensure pedalling is easier. But more importantly alloy rims are a more efficient braking surface than cheaper, chrome-plated steel rims, and are therefore safer.

    Little Details Count:

    • True cartridge bottom bracket for straighter chain alignment.
    • Shimano 9 speed trigger gearing system for maximum shift accuracy and reliability.
    • Super tough alloy wheels for reduced maintenance.
    • High performance hydraulic disc brakes.
    • Full grip pedals for added safety.
    • Machined surface rms for predictable braking.
    • Custom sized grips.
