Introducing the Frog 53 Hybrid Bike (20" 8-Speed), a versatile 20-inch hybrid bicycle designed specifically for children aged 5 to 7 years old. This top-of-the-line hybrid bike features a lightweight and durable aluminum frame, weighing only 18.0 lbs. Its maneuverability on various surfaces like roads, sidewalks, trails, and forest paths is unmatched. With Kenda Small Block Eight tires, the bike offers exceptional stability and grip. It comes complete with full-length mudguards and the option to attach a pannier rack, perfect for carrying school books and sports equipment.
The Frog 53 Kids' Bike is equipped with components tailored to your child's age. It has replaced the older Frog 52 and Frog 55 models. It includes a quick-release child-specific saddle for optimal riding comfort and FrogFit Technology® youth-specific 8-speed gear shifters. With their short lever travel and smooth cabling, changing gears and conquering hilly terrains becomes a breeze. The bike also features Tektro brakes with small, easily reachable brake levers, providing better control and boosting young riders' confidence. Additionally, our patented Frog cranks ensure effortless pedaling, reducing the distance between the pedals and enhancing efficiency and comfort for children.
Designed for longevity, the Frog 53 is optimized to grow with your child. Its lower bracket position guarantees a safer and more ergonomic riding experience, accommodating a wider range of leg lengths to suit growing kids. Furthermore, the handlebar height can be adjusted within a 40mm range as your child continues to grow, ensuring a perfect fit at all stages.

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.
