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.
