The Perfect Start to Cycling
Transitioning from a balance bike to pedaling has never been smoother. The Frog 38’s sturdy yet lightweight frame allows children to build confidence, develop control, and enjoy every ride. Parents love its portability, making trips to the park or school stress-free.
The child-focused design incorporates patented Frog cranks, smaller brake levers, and a perfectly sized saddle, ensuring your little one’s comfort and safety. Meanwhile, the innovative chainguard keeps the bike clean and low-maintenance, meeting ISO8098 safety standards.
Not Ready for Pedals Yet?
The Frog 38 can easily convert into a balance bike by removing the pedals. This flexibility helps kids build confidence at their own pace before transitioning to pedaling independently.
Find the Right Fit
Proper sizing is key to a positive cycling experience. The Frog 38 is designed for children with an inside leg measurement of 36cm to 41cm. Choosing a bike that fits well ensures better control, comfort, and safety.
Avoid buying a bike your child will "grow into," as oversized bikes can be heavy and challenging to handle, discouraging young riders. Frog Bikes are designed to meet children’s unique anatomical needs, making them lighter, easier to ride, and more enjoyable.
