The 20-inch Frog City 53 kids’ bike is the ultimate urban geared bike, suitable for 5 to 7-year-olds. This premium children’s city bike is designed for everyday use allowing kids to commute to school or explore the city in comfort and style. It has a lightweight, aluminium step-through frame, weighing just 8.45kg making the bike easy to mount and dismount and handle around town.
With this versatile city bike, kids will enjoy a more upright leisurely riding position, owing to a longer head tube and raised slightly swept handlebars. It is also equipped with 8-speed derailleur gears that provide more range for moderate speeds, and a floating chain glider to prevent clothing from getting stuck and the chain from getting soiled.
This urban kids’ bike comes with low-resistance Kenda city tyres perfect for riding on concrete & tarmac, full-length mudguards to keep clothes protected, a kickstand so that the bike is easy to park, and a pannier rack, for transporting books and equipment. And, it features our patented Frog cranks, for more efficient pedalling.
Get sized for cycling success
The Frog City 53 urban bike is suitable for 5 to 7 years with a recommended inside leg measurement of 49cm-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.

Great city bike with fenders, kickstand, bell… nothing more to add. My son loves it, feels independent, and I feel confident watching him ride it.

Super practical in town. We use it for the park, the market — everywhere. It’s easy to handle, sturdy, and really fits our son’s size.
