Frog City 53


The Frog City 53 kids' bike is the ultimate urban geared bike, suitable for 5 to 7-year-olds with a recommended inside leg measurement of 49cm-65cm. This premium children’s city bike is designed for everyday use allowing kids to 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 manoeuvre while they ride.

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. It also features our patented Frog cranks, for more efficient pedalling.

      Frog Bikes is a British company dedicated to making cycling fun for children. They have re-designed Kids’ bikes to create a light but strong aluminium frame, and have hand-picked components that offer high performance without compromising on weight.

      Frog bikes are also much easier to pedal due to a unique crank design from the renowned bicycle engineer Dimitris Katsanis (of Team GB Olympic fame). The design reduces the Q-factor (the space between the pedals), allowing children to push more directly down when cycling, so converting more of their energy into motion. This is another demonstration of the high level of rigour Frog applies to the design of kids’ bikes.  

      Besides leading the market in innovation and design for kids, Frog Bikes are also committed to protecting the planet, designing and developing products that are more sustainable as well as participating in projects that can help minimise the environmental impact on operations.
