Product Overview

The Frog 47 is a lightweight 18-inch pedal bike designed for children aged approximately 4 to 6 years. It supports the transition from smaller starter bikes to longer rides and developing cycling skills. With a child-specific frame design, easy-reach brake levers and an adjustable seat post, this bike is intended to help young riders build confidence and control at a manageable pace.

 

It is suitable for children with an inside-leg measurement of 43–59cm.
 

The Frog 47 is built to support early independent cycling. Its aluminium frame helps keep weight low, making the bike easier for children to control, lift or manoeuvre. Patented Frog cranks reduce pedal spacing to support a smoother pedalling motion and reduce fatigue on young legs.

 

With stable frame geometry, predictable handling and child-sized components, this model is designed to provide comfort and support as children ride on pavements, park paths and school routes. The bike can also be used without pedals for children who prefer to continue practicing balance before fully transitioning to pedalling.

Why Its Great For Families

✅Suitable for school runs, park rides and weekend cycling

 

✅Lightweight design makes it easier for parents to lift and store

 

✅Easily adjustable to accommodate growth

 

✅Can convert into a balance bike to support gradual learning

 

✅Encourages independent movement and outdoor time

 

Parents looking for a bike that fits well, supports gradual skill development and is manageable for young children may find this model appropriate.
