The 20 inch Frog City 53 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, aluminum step-through frame, weighing just 18.6 lbs. 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 dirty.
This urban kids bike comes with low-resistance Kenda city tires perfect for riding on concrete, 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 Frog's patented cranks, for more efficient pedaling.

* MINIMUM INSEAM measurement for a child who is large enough to ride this bike. Beginner (or timid) riders must reach the ground comfortably and flat footed while straddling the seat, meaning their inseam must be close to the minimum seat height. Experienced (or confident) riders will be more comfortable raising their heels off the ground when straddling the seat. See Kids Bike Sizing Guide.
† STANDOVER HEIGHT is measured from the top of the top tube to the ground, passing directly by the front of the chainring.
