Kids Bike Size Guide by Age & Height

What Size Bike Does My Child Need? – Kids Bike Size Guide by Age & Height

Choosing the right size bike for your child is key to building confidence, comfort, and safety when learning to ride. From balance bikes for toddlers to trail-ready mountain bikes for older kids, finding the perfect fit makes all the difference. Use our kids bike size guide to help you match wheel size to your child’s age and height—before you buy.

How Are Kids’ Bikes Sized?

Unlike adult bikes, which are sized by frame dimensions, children’s bikes are sized by wheel diameter. The most common sizes include 12”, 14”, 16”, 20”, 24”, 26” and 27.5” wheels, each suited to a specific age and height range.

Use the chart below as a quick reference to find the best fit for your child.

Kids Bike Size Chart – Age & Height Guide

Rider Height	Age Range	Recommended Wheel Size
86 – 102cm	2 – 4 years	Balance Bikes / 12″
99 – 117cm	3 – 6 years	14″ and 16″
114 – 132cm	5 – 8 years	20″
127 – 150cm	7 – 10 years	24″
146 – 170cm	10+ years	26″ and 27.5″

Balance Bikes & 12” Wheels (Age 2–4)

For toddlers and first-time riders, balance bikes are the perfect introduction to cycling. These pedal-free bikes focus on developing key skills like balance and steering, giving your little one the confidence to ride solo.

Ideal for: Ages 2–4 or heights of 86–102cm
No pedals or gears – powered by feet
Lightweight with 10”–12” wheels
Great models: Kids Ride Shotgun Hero, Frog Tadpole, Woom GO 1

14” & 16” Wheel Bikes (Age 3–6)

Once your child masters a balance bike, it’s time for their first pedal bike. Bikes in this category are simple and sturdy, usually single-speed with easy-to-use brakes—ideal for riding on pavements, park paths and light trails.

Ideal for: Ages 3–6 or heights of 99–117cm
Introduces pedals and brakes
Lightweight, durable frames
Suitable for both tarmac and light off-road use
Recommended models: Frog 38 (14”) and Frog 44 (16”) | Woom GO 2 (14″) and Woom GO 3 (16″)

20” Wheel Bikes (Age 5–8)

As your child’s confidence and strength grow, 20” wheel bikes offer more range and control. Often equipped with gears and front suspension, they’re perfect for exploring rougher terrain and longer rides.

Ideal for: Ages 5–8 or heights of 114–132cm
Introduces gears for varied terrain
Optional front suspension for comfort
Perfect for off-road trails and park riding
Top picks: Cube Acid 200 Disc, Merida Matts J.20, Woom Explore 4, Woom OFF 4

24” Wheel Bikes (Age 7–10)

With 24” wheels, bikes begin to closely resemble smaller versions of adult bikes. Built for pre-teens, these bikes cater to specific riding styles, whether it’s commuting, trail riding or leisure cycling.

Ideal for: Ages 7–10 or heights of 127–150cm
Gearing suited for hills and mixed terrain
Suspension forks and wider tyres on MTB models
Rigid forks and hybrid geometry for pavement and paths
Recommended: Cannondale Kids Quick 24, Cube Acid 240 Disc, Woom OFF AIR 5

26” & 27.5” Wheel Bikes (Age 10+)

For older children and young teens, 26” and 27.5” wheel bikes offer a near full-size riding experience with youth-specific geometry. These bikes support longer rides, more aggressive terrain and specialised disciplines like road cycling or mountain biking.

Ideal for: Ages 10+ or heights of 146–170cm
Scaled-down adult features and components
Suspension forks and wide gearing on MTBs
Drop bars and compact cranks on junior road bikes
Top models: Cube Nuroad Rookie (road), Whyte Secta 26 (MTB), Trek Marlin (26″ & 27.5″), Woom Explore 6 (26″)

Final Thoughts – Finding the Right Size Bike for Your Child

The right size bike ensures your child can ride confidently and safely, whether they’re just learning or tackling forest trails. Always measure height and consult a size chart before buying. If your child is between sizes, consider their experience level—beginners benefit from a smaller, easier-to-handle bike.

Wheelbase have 3 stores across the north of England where you can try Childrens bikes for size. If you order a childrens bike online at Wheelbase, it will arrive ready to ride, having been built and inspected by our Cytech Mechanics. On larger bikes you may need to add the front wheel.
