Who is this bike for?The first golden rule is to ensure that you buy a bike that fits your child properly. The second golden rule is to buy the best children’s bike you can. It also needs to be suitable for their abilities so try to avoid getting something that they will grow into.
About the BikeRemember how magical it was as a kid to be given a cool new bike? Let us help you recreate that for your little ones! Pinnacle’s kids’ bikes are solid but light in weight, sensibly designed for little legs, with a confident steering feel and thoughtful touches that will set your child rolling down the path to a lifetime of healthy enjoyment. A low bottom bracket, for example, creates a better geometry and is easier to balance, while rigid forks are lighter than often-ineffective suspension. The plastic Chainguard keeps you clean and rear-only gears keep the learning process simple. But they don’t need to know all that – kids can tell straight away that our bikes have been designed to maximise fun!
The Pinnacle Californium 20” is a perfectly scaled down version of our adult’s Californium city bike, with components and fit to suit younger riders. We’ve taken the features which make the adult’s bike a best-seller; Colour matched chaincase and mudguards to keep you dry and free from greasy chains, a basket to keep all your belongings whilst riding, and matching grips and saddle to finish off the package.Combined with all the details from our kid’s bike such as a lightweight aluminium frame and kid-friendly components such as short reach brake levers and push button gearing, the Californium 20” is the perfect bike for stylish young riders.
