Frog Kids’ Bikes


Frog is a small British company dedicated to making cycling fun for children. They believe that the lighter the bike, the easier it is for children to learn to ride and to enjoy it more as they progress.

Frog bikes feature strong aluminum frames and hand-picked components that offer a high performance and light weight.

What’s more, Frog bikes are now also much easier to pedal due to a unique crank design from the renowned bicycle engineer Dimitris Katsanis (of Team GB Olympic fame).  The new design reduces the space between the pedals, allowing children to push more directly down when cycling, converting more of their energy into motion.  Only Frog applies this level of rigour to the design of kids' bikes.

We carry a range of Frog bikes - sized for riders ages 4 to 12+. Hover over each model above for size recommendations.

Frog 40

The First Pedal Frog 40 is a great value bike for 3 to 4 year olds with an average inside leg of 40cm.

Wheel Size: 14" inch

One of the biggest temptations is to buy a bike your child will 'grow into'. However, this is likely to have the opposite effect and put your child off bikes and cycling altogether! The data obtained during our child-specific frame design research has been used to produce a helpful sizing app. Ask in your local store about our FrogFit app to get the best-sized bike for your child.

Another common mistake is to purchase a budget bike but these models are often as heavy as the child and leads to frustration at not being able to cycle. Our lightweight bikes are a great confidence booster and can also be used as a balance bike for a taller child by removing the pedals.

Frog 44

The First Pedal 44 is the first in our new and improved frame range. It is the perfect, great value bike for 4 to 5 year olds with an average inside leg of 44cm.

Wheel Size: 16" inch

We have reduced the weight of this model by using smaller tube diameters and thinner tube walls. The Frog 44 weighs only 6.39kg. Along with this weight saving, we have lowered the bottom bracket to achieve a more ergonomic position on the bike.

Frog 52

The First Pedal 52s is a great value bike for 5 to 6 year olds with an average inside leg of 52cm.

Wheel Size: 20" inch

This bike is a great confidence booster for a taller child that hasn't quite learnt to cycle yet. This versatile model can act as two bikes in one - both a Balance Bike and Pedal Bike and can teach an older child to balance before moving to pedals. To use the 52s as a Balance Bike all you have to do is remove the pedals and when your child is ready to pedal simply put them back on!
