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.
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 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.
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.

When it comes to choosing the right size kids bike, our over-riding advice is 'smaller is better than bigger'. Children learn to ride with greater ease, have more control on the bike and have a lot more fun if they are the master of their domain.
It is all too common to see parents using height as the only key measurement for a bike's correct size. Be careful: it can easily be misleading as an indicator. As most kids' balance develops at roughly the same speed, using age with ability is far more relevant. If you can add age, with height, and ability (ability is a hard one to measure but as a parent you must be honest and realistic) and confidence, than you have a really good indicator.
The most common reason kids have to move up a size on a normal bike is because of the lack of knee room between the seat and handlebars. This forces you to put up the seat and then your child loses interest or confidence in riding because the centre of gravity is really high and hence the bike becomes even more difficult to ride.
Here are just a few of the frequently asked questions we get about riding kids bikes. If you've got a specific query that is not answered here, please do not hesitate to contact us: info@bykbikes.com or message us on Facebook
A kids bike that has a lower centre of gravity will ensure it is easier to control at any speed. From start up speed for learners to high speeds for budding dare devils, the superior distribution of weight of the ByK kids bikes ergonomic design inspires confidence and control in the rider.The low centre of gravity design is part of our total ergonomic concept. Compared to the top of the wheels, the heavier elements of the bike are sitting lower or deeper into the wheels. It is our unique design and you may see this visually illustrated on our safety page. Effectively we have helped to stabilise the rider and distribute their weight and the bike weight to a position of better control.
After design & efficiency, the next most important aspect is weight. This applies to all bikes and in kid's bikes we have found most bikes on the market are over-weight! The average adult bike weighs approximately 15kgs with the expected rider to weigh between 60-90 kg. By comparison, the average children's bike weighs 13kgs for a child weighing around 20kgs.
You can clearly see the kids have their work cut out. By making our bikes 20% lighter, the rider benefits hugely in many ways, especially bike control. Every little bit of weight we have saved will benefit your child as it does on an adult bike; just multiply the affect by more than two!
Our ByK bikes superior efficiency is possible because we have an innovative design and genuinely lighter weight, but also from our more efficient wheel dynamics. We have achieved this by reducing the rolling resistance of the tyres while increasing the overall rolling size of the wheels. One major benefit from our big wheel concept is the significance it has on reducing the time it takes to get a stationary bike up to balance speed, a critical advantage for all new riders.
