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.
