The 26-inch Frog City 67 kids’ bike is the ultimate urban geared bike
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 9.61kg 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. The data obtained during our child-specific frame design research has helped us create a helpful kids’ bike sizing app.
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. The Frog City 67 urban bike is suitable for 10 to 12 years with a recommended inside leg measurement of 63cm-81cm. 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.
