At Frog, we take sizing a child very seriously. This is one of the most important factors for cycling
success and enjoyment.
While other brands focus on the age of your child, their height or even bike wheel sizes, at Frog we know
that finding the perfect
size kids’ bike for your child is all about your child's inseam plus their confidence in riding.
Kids grow at completely different rates, meaning age or height is not a reliable way to determine the right
size kids’ bike.
Our children’s bikes
are sized based on inseam rather than age, which is the most reliable way to find the right size bike for
each child.
How to find the right size bike for your child
How are kids' bikes measured?
To ensure your child rides safely and comfortably, it's essential to check that they can reach the
ground with their feet while
seated on the bike. The best way to do this is by measuring your child's inseam. This will help you
choose the correct bike size,
improving safety, control, and comfort while cycling.
How to measure your child’s inseam for the perfect bike fit
Have your child stand in socks with their back against a wall.
Place a small book or similar object between their legs, as high as is comfortable.
Ask the child to move away from the wall, then measure the distance from the top of the book to
the floor.
Use the inseam measurement to find the ideal bike size from the chart below.
How to choose the right kids’ bikes
For kids just learning to ride, a lightweight
10” balance bike, 12” balance bike or
14” balance bike is typically ideal, as this will help them learn
the art of balance and
coordination before moving on to a first pedal
bike. However, if your child is
learning to ride at an older age, their wheel size needs will adjust accordingly.
When children grow taller and require bikes with 26” wheels, they often face the challenge of
transitioning to adult-sized bikes.
Unfortunately, adult bikes are significantly heavier and harder for kids to control. Frog Bikes
solves this problem by offering a
wide range of lightweight, high-quality 26” wheel bikes specifically designed for kids. These
include children’s
hybrid bikes, road
bikes,
track bikes, mountain bikes,
and
city bikes, ensuring taller children can continue riding
comfortably without being
pushed into adult-sized bikes before they’re ready.

*Age, Wheel Size, and Frame Size are approximate. Always prioritize inseam measurement.
When choosing the perfect bike for your child, inseam length is just one factor. Standover height and
saddle height are also crucial
for ensuring your child can comfortably stand over the bike and touch the ground while seated. These
measurements improve control
and confidence, especially when starting, stopping, and navigating uneven terrain. Proper fit ensures a
safer, more enjoyable riding
experience.
We recommend purchasing your Frog bike either directly from our website or a local stockist. Your local
stockist will build and fit
the bike for you, ensuring the best fit for your child.
