The Frog 38

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.
A bike that grows with your child
The Frog 38 14-inch first pedal bike is designed to grow with your child, featuring an adjustable handlebar height and tool-free seat post adjustment. As your young rider grows taller and stronger, the bike easily adapts to ensure a perfect fit, providing long-lasting comfort, confidence, and a better riding experience.
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.
The perfect transition from a balance bike
Not quite ready for pedals? The Frog 38 kids' first pedal bike offers the perfect solution by easily converting into a balance bike - just remove the pedals. This flexible design allows children to develop their balance and coordination at their own pace, making it an ideal choice for those transitioning from balance bikes to their first pedal bike. It's a seamless way to build confidence and ease into pedalling.
