New for 2026! Pre-order now for late August arrival E-350 | AGE: 4 - 6 YEARS | HEIGHT: 95 - 117CMS Ability Level: Able to ride or ready to learn. This bike redefines children's bikes for innovation and excellence. 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: At the heart of every ByK Bike is a well designed frame and weighing in at less than 10kg, your child will have a light and easy bike to ride. 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.
