    THE BIKE EVERY KID WOULD LOVE TO LEARN ON…WITH MORE!

    E-350X3I| AGE: 4 – 6 YEARS | HEIGHT: 95 – 117CMS

    Ability Level: Able to ride or ready to learn.

    Featuring all the superior design of the E-350 range with the incredible innovation of speed sensitive gears.

    No levers, no cables, no chance of anything going wrong, just simply a clever gear system that changes up and down at the designated speed.

    Smooth handling, safe, ultra-efficient. Just 8+kgs.

    Design:

    With no external moving parts and designed by Shimano for electric bikes and folding bikes, the internal 3-speed i-motion gear system has been customised to suit the E-350.

    At the heart of every ByK Bike is a well designed frame and lightweight frame – so your child will have a light and easy bike to ride. Small children have a narrow pelvis. We believe for a child to ride comfortably and in the correct position, the saddle should be padded and matching the size of their body – we have done just that with the E-350.

    Performance:

    With lightweight alloy wheels, we’ve 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 we 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.

    We 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. 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:

    • Increased knee to handlebar clearance for growing bodies.
    • Alloy seat clamp.
    • Custom length cranks.
    • Pedals with bearings.
    • Smooth running tyres to reduce road friction and noise so your child can hear safety instructions.
    • Ergonomic riding triangle between pedals, seat and handlebar for best balance and efficiency.
    • Long wheelbase for more predictable handling at higher speeds.

    THE BIKE EVERY KID WOULD LOVE TO LEARN MOUNTAIN BIKE SKILLS ON… AND MORE.

    E-350MTB | AGE: 4 – 6 YEARS | HEIGHT: 95 – 117CMS

    Ability Level: Able to ride or ready to learn.

    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 Shimano 3 speed internal gears, calibrated for off-road use.

    We have 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 ultra-efficient tall wheels, safe braking with a footbrake and two calibrated alloy handbrakes, every single component has been carefully selected. Just 8+kgs.

    Design:

    Committed to the ultimate off road potential, the E350MTB is a machine that inspires fun and adventure. While the enemy of kids MTB’s is typically sluggish handling and heavy weight, the ByK E350MTB is seriously light.

    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 believe for a child to ride comfortably and in the correct position, the saddle should be padded and matching the size of their body – we have done just that with the 350MTB.

    Performance:

    With lightweight alloy wheels, we’ve made pedalling easier; professional bike riders insist on them so why shouldn’t our kids too! And the custom-fit knobby tyres are not as fast-rolling as the standard E-350 but they don’t need to be. You’re buying a mountain bike that can handle the road but handles the rougher terrain even better. At just over 8kgs, the 350MTB 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. We 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.

    E-450X8 | AGE: 6 – 9 YEARS | HEIGHT: 115 – 145 CMS

    Ability Level: Able to ride with some developed skills and has reasonable responsibility. Ready for handbrakes only.

    We have combined our low gravity concept ergonomic frame with the very best cassette gears and tough wheels for the greatest safety and rideability.

    It delivers a dramatic advantage in handling and comfort – with each tube of the frame customized to reduce weight and improve handling, and superior control and bump dampening ability with our CRM forks. Just 10kgs.

    Design:

    With the E-450×8 frame we customised each tube to reduce weight and improve handling. Another crucial ingredient to the clever design is the improved control and bump dampening ability of our CRM forks – giving a dramatic advantage in handling and comfort.
