Product Details

On the MTBD kids mountain bike range, your kids will enjoy our cutting edge geometry and attention to exacting detail with a full compliment of durable lightweight components for a ride to remember. The evolution of the ByK Mountain series bikes takes on new challenges and exciting adventures.


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.


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 SRAM 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 560MTBD re-defines MTB fun for kids.


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. With reach-adjustable hydraulic disc brakes, the same as on many adult MTBs, the MTBD range offers unparalleled control.
