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 46cm. 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.

Frog Bikes
is a British company specializing in lightweight, high-quality bicycles designed specifically for children aged 1 to 14. Founded in 2013 by Jerry and Shelley Lawson, the company emerged from their personal quest to find suitable bikes for their own children. Collaborating with sports scientists at Brunel University and renowned bicycle engineer Dimitris Katsanis, Frog Bikes developed child-specific bike geometry, ensuring comfort and efficiency tailored to young riders.
In 2016, Frog Bikes relocated its manufacturing from China to a 120,000 sq ft facility in Pontypool, Wales, enhancing quality control and reducing lead times. The company has received support from the Welsh Government and was honored with the Queen’s Award for International Trade in 2018. Today, Frog Bikes operates in over 56 countries, with exports accounting for more than half of its turnover.
Committed to sustainability
Frog Bikes joined the Race to Zero campaign in 2021, aiming to reduce emissions by 50% by 2030 and achieve net-zero emissions by 2050. Their product range includes balance bikes, hybrid bikes, mountain bikes, and road bikes, all designed with lightweight aluminum frames and child-specific components.
