The 26-inch hybrid Frog 78 kids’ bike is the ideal multi-purpose geared bike, suitable for 13+ year-olds. This premium hybrid children’s bike has a lightweight, sturdy aluminum frame, weighing 22lbs making the bike easy to maneuver on roads, pavements, towpaths and forest trails. It comes with Kenda small block eight tires 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 78 kids’ bike is equipped with age-specific components, including a quick-release saddle for the perfect riding position and FrogFit Technology® youth-specific 8-speed gear shifters with short lever travel and ultra slick 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 pedaling, which reduces the distance between the pedals increasing efficiency and comfort for children.


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.
