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 our rider's profile.

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


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.


From our 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 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:

- True cartridge bottom bracket for straighter chain alignment.
- Shimano internal gears forleast resistance, ease of change and durability.
- CRM forks for extra comfort and improved handling.
- Long rear stay length for best possible gear shifting
- Super tough alloy wheels for reduced maintenance.
- Calibrated V-Brakes for progressive braking.
- Full grip pedals for added safety.
- Machined surface rms for predictable braking.
- Custom sized grips.
