Frog 38: The Ultimate First Pedal Bike for Kids

Why Choose the Frog 38?

  • Perfect for Growth: Adjustable handlebar height (40mm range) and toolless seat post adjustment ensures the bike grows with your child.
  • Effortless Riding: Patented Frog cranks improve pedaling efficiency and comfort, while the lightweight aluminium frame makes it easy for kids to handle and parents to carry.
  • Safety First: Small, easy-to-reach brake levers offer better control, boosting rider confidence.
  • Sleek & Practical Design: The innovative new low-profile Frog chainguard system and included Insane Chains chainguard reduces weight and enhances the bike's modern look.
  • Kid-Friendly Features: Enlarged grip ends protect little hands when riding near obstacles, and a new kickstand attachment ensures safer deployment.
  • Easy Maintenance: A redesigned lightweight aluminium chain tensioner simplifies adjustments.
  • Built to Last: Backed by a free 10-year extended warranty on the frame and forks.
  • Weight Saving: Thinner profile frame tubing saves weight over the Frog 40.

Includes: Reflectors, mudguard, and bell for added safety and functionality.

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.

Use our bike sizing guide or visit a local Frog Bikes stockist to ensure the perfect fit.

Note: All Frog First Pedal bikes come with compliant chainguards to meet ISO8098 safety standards.
