FIT FOR FUN: A PARENT’S GUIDE TO KIDS BIKE SIZES
At PAU, we understand the importance of getting the right bike size for your child’s cycling success and enjoyment. That’s why we’re proud to offer Frog bikes, which are sized based on leg length rather than age. Unlike many kids’ bikes, this approach ensures a more accurate fit, catering to the unique shapes and sizes of children.
Children grow at different rates, making age alone an unreliable measure for bike sizing. By focusing on inseam measurement, we can better match your child to the right size bike for their comfort and safety.
To find the perfect bike fit for your kids, follow this simple measuring technique recommended by Frog Bikes:
- Stand your child in socks against a wall.
- Place a small book between their legs at a comfortable height.
- Measure from the top of the book to the floor.
- Use the measurement to select the appropriate size bike from our Frog bikes range.
Don’t rely on outdated methods like; trust PAU to help you find the perfect bike size for your child’s cycling adventures. Come in store for a personal bike fitting, or check out this guide on Frog bike sizes for kids below.
