The 20-inch hybrid Frog 53 kids’ bike is the ideal multi-purpose geared bike, suitable for 5 to 7-year-olds. This premium hybrid children’s bike has a lightweight, sturdy aluminium frame, weighing 8.15kg making the bike easy to manoeuvre on roads, pavements, towpaths and forest trails. It comes with Kenda small block eight tyres for maximum stability and grip, full-length mudguards and the option to attach a pannier rack to the frame, for transporting school books and sports equipment.
 
The Frog 53 kids’ bike is equipped with age-specific components, including a quick-release child-specific saddle for the perfect riding position and FrogFit Technology® youth-specific 8-speed gear shifters with short lever travel and ultraslick cabling making changing gear and undulating rides a breeze. The bike also comes with Tektro brakes with small, easy-to-reach brake levers, which means better control and improved confidence for young riders. And, our patented Frog cranks, for more effortless pedalling, which reduces the distance between the pedals increasing efficiency and comfort for children. 
 
The Frog 53 is designed for longevity and has been optimised to help maximise the lifetime of the bike for a growing child. It offers a lower bracket position to ensure a safer more ergonomic riding experience, which also allows for a greater leg-length range to be accommodated, perfect for growing legs. And the handlebar height can be adjusted within a 40mm range, as a child grows.
 
Get sized for cycling success
The Frog 53 hybrid bike is suitable for 5 to 7 years with a recommended inside leg measurement of 50cm-65cm.
 
One of the biggest temptations is to buy a child's bike that they will grow into. However, this will likely have the opposite effect and put your child off bikes and cycling altogether! Another common mistake is to purchase a budget kids' bike but these models are often as heavy as a child which can lead to frustration at not being able to cycle. That’s why Frog bikes are lightweight and designed to specifically accommodate the anatomy of children.
