Here’s everything you need to know, plus our top bike recommendations for how to choose a bike for a 5-year-old...
Watching your child learn to ride a bike is one of those unforgettable parenting moments, right up there with their first steps or first words. It’s a mix of wobbly starts, big smiles, and the proudest high-fives. At Frog Bikes, we know just how important it is to get that first bike right. So we’ve created a range of kids’ bikes that support kids (and their parents!) every step of the way.
Here’s our guide to the best Frog bikes for beginners and how they can make learning to ride easier, safer, and way more fun.
But first - a balance bike! - Tadpole balance bike (Ages 18 months to 4 years)
Before pedals come balance skills and the Tadpole 12” balance bike is where it all begins.
This isn’t just a cute little balance bike for toddlers, it's a secret weapon for learning to ride. The Tadpole helps little ones develop balance and coordination from the get-go, so by the time they’re ready for pedals, they’ve already nailed the trickiest part. And since there are no stabilisers or clunky training wheels in sight, they can focus purely on building their confidence.
Light as a feather: The lightweight frame is easy for toddlers to push, glide, and even carry (or for parents to carry when energy runs out!).
Sized just right: With an adjustable seat and handlebars, the Tadpole grows with your child, because we all know toddlers don’t stay one size for long.
Brakes made for tiny hands: Tektro child-friendly brakes help kids learn how to stop safely, even at a gentle roll.
Packed with personality: Available in a rainbow of colours and three sizes (Mini, Regular, and Plus) based on your child’s inside leg measurements, so you can find the perfect fit and style. The three balance bikes from Frog are perfect for young kids with an inside leg measurement between 24–47cm. Find out more here…
Why parents love the Tadpole
Encourages balance and coordination
Makes the transition to pedal bikes smoother
No need for stabilisers
Durable, quality construction (but not heavy!)
Parent Tip: Many children go straight from a Tadpole to a pedal bike without ever using stabilisers. It’s that effective.
Ready to pedal! - Start with the Frog 38 (Ages 3-4)
Your little one has mastered the art of balance, now they’re ready for their first pedal! The Frog 38 is our newest and smallest 14” pedal bike (which has now replaced the Frog 40), created for children with an inside leg of 36-41cm. If your child is 3-4 years old and itching to ride “like the big kids,” this is your go-to kids’ bike.
Built just for kids: Every part of the Frog 38 is made with small riders in mind, from the crank length to the brake lever reach.
Scientifically designed: Our patented FrogFit Technology, developed with experts at Brunel University, ensures the perfect ergonomic fit.
Ready to ride:It comes with all the essentials, bell, reflectors, and mudguards, right out of the box.
Full of flair: Choose from a range of vibrant colours to suit your little cyclist’s personality.
Why the Frog 38 is ideal for first-time pedal riders
Lightweight frame (just 6.46kg!)
Child-specific components = better control
Low centre of gravity for easy balancing
10 year warranty on frame and forks for peace of mind
Parent Tip: The Frog 38 is perfect for kids coming off a balance bike—it’s small, sturdy, and gives them instant confidence.
Frog 44 (Ages 4-5)
As your child grows in height and confidence, it’s time to level up. The Frog 44 16” kids’ bike is the natural next step, designed for children with an inside leg of 40-53cm and ready for more independent riding.
Whether they’re zipping down the pavement or exploring the local park, the Frog 44 offers a stable, supportive ride that helps kids go further and feel prouder every time.
Still lightweight (6.39kg), so your child can handle it with ease.
Child-specific build for better posture, control, and comfort.
Patented FrogFit Technology ensures a comfortable, confident riding position.
Comes with the extras: bell, reflectors, and mudguards included.
Parent Tip: Both, the Frog 38 and Frog 44, can be used as a balance bike by simply removing the pedals. Why not try it if your kid is not ready to cycle just yet.
