Simplicity and functionality are the hallmarks of this rider-friendly bike.

Their unique ergonomic riding position and geometry, along with premium components is unprecedented for a bike of this size.

Shimano ultra smooth 3 speed gears, along with their responsive handling to increased safety at speed, make this bike easy and fun to ride. Just 12kg.

Design - The E-620x3i is uniquely designed for children and is not a scaled down adult bike. Every single component has been considered, tested, custom sized and tuned to suit their rider's profile.

Their unique ergonomic riding position and geometry along with their selection of premium components together offer a range of riding positions and adjustability unexpected at this size.

Performance - Shimano ultra smooth and class leading efficient internal 3 speed gears couldn't be easier to use.

Strong wheels, durable tyres, tough tubes, comfortable ergonomic saddle, custom shaped handlebars, short reach and long reach pedal position, sealed bearings, grippy pedals and so so much more really separate ByK from the regular offering.

Safety - From their responsive handling to increased safety at speed, the ByK 620 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 they 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.
