Looking for the perfect first pedal bike for your child?

The Frog 38 is thoughtfully designed for young riders aged 3 to 4 years. Replacing the Frog 40, this lightweight and durable kids' bike is perfect for little adventurers. Built to make learning to pedal a fun and confidence-boosting experience, the Frog 38 helps children build balance, strength, and coordination. It's the ideal first bike for kids, creating memorable moments as they ride off on their own for the very first time! The Frog 38 is suitable for children with an inside leg measurement of 36-41cm.

Designed for easier pedalling

The Frog 38 kids' first pedal bike features patented Frog cranks (made using 75% recycled aluminium), designed to provide a more efficient pedalling motion that's gentler on young legs. This patented, innovative design makes cycling smoother and more enjoyable for kids while helping them build strength, coordination, and confidence as they develop their cycling skills.

Lightweight for kids and parents

Weighing only 6.06kg, the Frog 38 14-inch bike is an incredibly lightweight kids' bike that's easy to handle and manoeuvre. Young riders will feel confident as they navigate their first rides, while parents will love the bike's portability, whether carrying it to the park or lifting it into the car. The bike's thin-profile aluminium frame (made using 30% recycled aluminium) provides a sleek, streamlined look without sacrificing durability or strength.

Confidence-boosting safety features

Safety comes first with the Frog 38 kids' bike. Small, easy-to-reach brake levers are designed specifically for young hands, helping children learn to stop with greater control. The responsive braking system, combined with a low centre of gravity and a stable frame, helps little riders stay balanced and in control, while enlarged handlebar grips offer extra protection during tumbles or sharp turns.

Sleek and kid-friendly design

The Frog 38 14-inch first pedal bike is designed with safety in mind, featuring a sleek, low-profile chainguard that helps protect little fingers and keeps clothes clean, while still looking great. Its innovative Insane Chains chain protector adds an extra layer of security and reduces maintenance for parents. The frame is also kickstand-ready, making it easy to add one later for added convenience and stability.

Ready to ride - What's included?

The Frog 38 is designed with essential safety features and convenient kids' bike accessories, including reflectors for enhanced visibility, mudguards (worth £28) to keep clothes clean, and a bell for added fun. While the kickstand isn't included, it's available to be purchased separately, giving you the option to add even more convenience to your child's first pedal bike experience.
