Bicycles require some assembly. This may include fitting the wheels, handlebars, pedals, seatpost and seat, and front brake caliper. This should not be attempted by the customer unless familiar with modern bicycle assembly and should otherwise be carried out by a competent bicycle mechanic. This includes bicycles sent to our stores for in store pick up, however, your local Bikebug store can assemble the bicycle for a fee, please contact your local Bikebug store after placing your order.

Design - At ByK we know kids love to be like their heroes, on the 540CXR they can be ready to race around the cyclocross track like a pro and ride to school the next day. Our unique design makes it possible to ride on the roads smoothly as well dabble in triathlons or touring.
Their clever integrated child specific gear design combine with premium components for a lightweight, versatile and strong dream machine.
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 - Their newest bike is trail inspired but what really shines about the E-540CXR is that it handles the vast variety of real world riding challenges like no other.
From their lightweight ergonomic Alloy frame and CRM forks to the durable wide, knobby race tyres with high puncture resistance and the custom sized handlebars and stem for the best possible control and comfort, every details has been considered.
Microshift's innovative gear/brake shifters are child specific, super easy to reach and use and we have combined them with our premium cassette, gear changing is taken to a new level for kids road bikes.
Safety - Safety is paramount for ByK and with the E540CXR ByK takes safety to a new level for a kids bike. From our predictive handling and shock absorbing geometry to the coolest and great stopping power of our mini v-brake system. 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. Their 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.

How To Determine Your Size
ByK Bikes are not categorised by the old imperial sizings of the past (like 12", 16", 20", or 24"). They use the metric system to describe their wheel sizes as 200mm, 250mm, 350mm, 450mm, 540mm and 620mm. Please use this chart to determine the bike size best suited to your young rider.
