About ByK E-350 Boys Bike - Matt/Gloss Black

Bike Assembly Required

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.

This bike redefines children’s mountain bikes for innovation and excellence. Featuring all the superior design of the E-350 range with the super cool SRAM 3 speed internal gears, callibrated for off-road use. ByK modified the handlebars to a lower profile V bar for better weight distribution in those more challenging circumstances and of course added custom-fit knobby tyres to handle the toughest terrain. From the smooth handling long wheelbase to the efficient tall wheels, safe braking with a footbrake and two calibrated alloy handbrakes, every single component has been carefully selected.

On the MTB kids mountain bike range, your kids will enjoy the ByK cutting edge geometry and attention to exacting detail with a full compliment of durable lightweight components for a ride to remember. We have taken this children's mountain bike to a new level of efficiency, safety and riding dynamics.


Alloy seat clamp

Custom length cranks

Pedals with bearings

Custom-fit knobby tyres to handle off-road terrain

Ergonomic riding triangle between pedals, seat and handlebar for best balance and efficiency

Long wheelbase for more predictable handling at higher speeds

Design - At the heart of every ByK Bike is a well designed frame and weighing in at less than 1kg, your child will have a light and easy bike to ride. Small children have a narrow pelvis. Byk believe for a child to ride comfortably and in the correct position, the saddle should be padded and matching the size of their body - Byk have done just that with the E-350.

The Celeste Green Retro model also comes with Mud Guards and Front Basket.

Performance - With lightweight alloy wheels, Byk made pedalling easier; professional bike riders insist on them so why shouldn't our kids too! And the smooth, faster-rolling tyres don't wear little legs out so quickly - as opposed to regular BMX kids bikes that have wide tyres with big knobs that most kids struggle to get going on. At just over 8kgs, the E-350 is approximately 30% more efficient than comparative kids bikes.

Safety - To make a children's bike safe, the rider needs to be able to brake efficiently and confidently. On the front Byk have used an alloy side pull calliper for developing immediate hand control, and at the rear a coaster brake for simple and safe foot braking.

Byk have used alloy front and rear callipers with light action for superior control and a simple and safe coaster style foot brake. The best of both worlds we believe. 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.

More About The Manufacturer ByK Bikes

The ByK [prounounced 'bi-kay'] Bike was born from one father's desire to build a bike that was made specifically for children. One that was suitable for a child's growing body and differing proportions to that of an adult. Warren Key has owned bicycle stores his whole life and knows a thing or two about bike design. He has a 12, 10 and 6 year old and realised early on that there were no well designed bikes on the market for children, anywhere in the world. After a few years of research, design and prototypes, the ByK Bike is now available for Australian children to own.
