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.
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.
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.

The frame is also kickstand-ready, making it easy to add one later for added convenience and stability.
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.
