Whether you are researching kids’ bikes for the first time, or looking to upgrade a bike to the next size, you’ve probably wondered why are children’s bikes usually categorised by 12", 16", 20", or 24”, and why are ByK Bikes not?
Categorisation of kids bikes by wheel size in inchesKids bikes have, for as long as we remember, been categorised in the older, imperial system by measuring the wheel size in inches. Oddly, this dated ‘inch-sized’ measuring system is a little misleading, as the true size of the wheel is often quite different. For example, 16” translates literally to 406.4mm. However, a typical 16" wheel size bike you’ll find in stores today has an actual rim diameter of 305mm! This is probably because over time, wheel size choices at the manufacturing level have changed, but the customer expectation of a category system they were used to didn’t, so bike manufacturers decided to stick with it.
Why are ByK bikes not categorised in inches?When we started ByK Bikes, we wanted to change the way we looked at kids bikes and really innovate the design. So, to begin with we went metric - we’re an Australian-based company so it made sense. And we wanted to be consistent with the next generation of parents and kids who were looking for a better kids bike, and not be bound by old, out-of-date traditions. So we took a fresh look at kids bikes with their overall design and the ergonomics of a kids growing body. This was more than just changing over to metric. We increased the wheel size for better dynamics and rolling efficiency. Thereby creating our own, new category system, ignoring traditional wheel size altogether. Explaining how to compare ByK Bikes to traditional kids bike sizes is not as simple as saying that we increased the wheel size. Increasing the wheel size of a kids bike, and introducing a low centre of gravity design, is just a small part of our total ergonomic concept. Our unique design is why Scienceworks included us in their exhibition, alongside a raft of Australian inventions such as the black box flight recorder, the polymer bank note and the multichannel cochlear implant, that explored themes of innovation and inventiveness.
