More About The Manufacturer ByK Bikes

The ByK [prounounced 'bi-kay'] Bike was born from one father's desire to build a bike that was made specifically for children. One that was suitable for a child's growing body and differing proportions to that of an adult. Warren Key has owned bicycle stores his whole life and knows a thing or two about bike design. He has a 12, 10 and 6 year old and realised early on that there were no well designed bikes on the market for children, anywhere in the world. After a few years of research, design and prototypes, the ByK Bike is now available for Australian children to own.
