Children’s Bike for Girls & Boys: How to Choose the Right One

Getting your child their first bike is an exciting milestone. Whether it’s a birthday gift, a Christmas surprise, or simply the right time for your little one to start pedaling, choosing the right children’s bike can make all the difference between a child who loves cycling and one who finds it frustrating.

Not all kids’ bikes are created equal. A bike that’s too big, too heavy, or not suited to your child’s age and ability can knock their confidence before they’ve even got started. On the other hand, the right children’s bike — one that fits perfectly, feels comfortable, and matches their riding style — can spark a lifelong love of cycling.

At CT Bikes, we stock a wide range of children’s bikes for girls and boys, from beginner balance bikes for toddlers all the way up to geared mountain bikes for older kids and juniors. In this guide, we’ll walk you through everything you need to know to choose the perfect bike for your child — including size guides, age recommendations, bike types, safety tips, and our top product picks.

1. Understanding Children’s Bike Sizes: The Wheel Size Guide

The most important factor when buying a children’s bike is getting the right size. Unlike adult bikes (which are measured by frame size), kids’ bikes are measured by wheel diameter in inches. To make sizing easier, here’s a simple breakdown:

How to Measure Your Child for a Bike

The easiest method is to measure your child’s inseam length (inside leg measurement). When seated on the bike saddle, your child should be able to place both feet flat — or nearly flat — on the ground. This gives them confidence and control, especially when starting out.

A good rule of thumb: always size down rather than up. Many parents make the mistake of buying a bigger bike thinking their child will “grow into it.” This can actually slow down learning and reduce confidence. A well-fitting bike that’s slightly small is always better than one that’s too large.

Bikes for Toddlers (Age 2–4): 12 & 14 Inch Bikes

For the youngest riders, a toddler bike or balance bike is often the best starting point. Balance bikes have no pedals — children propel themselves with their feet and learn balance and steering naturally. This makes the transition to a pedal bike much smoother later on.

If your toddler is ready to pedal straight away, a 12-inch or 14-inch kids bike with stabilizers is a great option. Stabilizers (also called training wheels) provide extra support while your child builds confidence.

Top Picks at CT Bikes:

• Viking Sparkle Girls 12″ Wheel Single Speed — a gorgeous starter bike for little girls, beautifully designed and easy to handle
• Viking Rascal Boys 12″ Wheel Single Speed — a sturdy, fun option for toddler boys taking their first pedal strokes
• Viking Enchanted 14-inch Single Speed Girls Bike (Age 3–5) — perfect for slightly older toddlers ready to explore

Key Features to Look For:

• Lightweight frame (easier for small children to handle)
• Adjustable saddle height
• Easy-grip handlebars
• Coaster brakes or simple hand brakes
• Removable stabilisers

Bikes for Young Children (Age 4–6): 16 Inch Bikes

At this age, most children are ready to ditch the stabilizers and ride independently. A 16-inch bike offers the right balance of maneuverability and stability for this age group.

Look for bikes with single-speed gearing (no gear changes needed), simple hand brakes, and a fun design that your child will be excited to ride.

Top Picks at CT Bikes:

• Viking Angel 16 Inch Kids Bike Single Speed (Age 4–6) — light, easy to ride, and beautifully designed for young girls and boys
• Viking Monster 14 Inch Kids Bike (Age 3–5) — a bold, exciting design that young boys will absolutely love

What to Consider:

• Can your child reach the brakes comfortably?
• Is the saddle adjustable to grow with them?
• Does the bike have a chain guard for safety?
• Is the overall weight manageable for your child?

Bikes for School-Age Children (Age 6–9): 20 Inch Bikes

Once your child starts school and gains more confidence on two wheels, a 20-inch kids bike opens up a whole new world of cycling possibilities. At this stage, you can start introducing geared bikes — particularly if your child will be riding on varied terrain, hills, or longer distances.

Top Picks at CT Bikes:

• Falcon Cobalt 20-Inch Junior Bike (6 Speed, Full Suspension) — a brilliant choice for adventurous kids who want to tackle different terrains. With full suspension and 6 speeds, it’s built for real riding.
• Tiger Warrior 20″ Wheel 14″ Frame — a striking, high-quality bike that combines style with performance for school-age riders

Features Worth Having at This Stage:

• Multiple gears (6-speed is ideal for beginners)
• Front or full suspension (for off-road adventures)
• Reliable hand brakes
• Lightweight but sturdy alloy frame
• Adjustable saddle and handlebars

Bikes for Older Children & Juniors (Age 8–12): 24 Inch Bikes

Older children need a bike that can keep up with their growing confidence, strength, and sense of adventure. A 24-inch kids bike bridges the gap between children’s and adult bikes perfectly.

At this age, your child may develop specific interests — mountain biking, BMX, road cycling — so it’s worth considering what type of riding they’ll mostly be doing.

Top Picks at CT Bikes:

• Elswick Eternity 24 Inch Blue and Pink Bike Girls (6 Speed) — an elegant, capable bike for older girls who want style and performance. Originally priced at £239.99, now available at just £149.99 — exceptional value!
• Dawes 14″ Thunder Junior Bike — a trusted British brand delivering quality and reliability for growing riders

3. Children’s Bike for Girls: What to Look For

When choosing a girls bike, there are several things to keep in mind. Modern girls bikes have evolved significantly — they’re no longer just “pink versions” of boys bikes. For that reason, today’s best girls bikes combine great design with proper performance features.

Key Considerations for Girls Bikes:

Frame Design: Many girls bikes feature a lower top tube (step-through frame), which makes it easier to mount and dismount — particularly useful for younger riders in skirts or dresses.

Color & Style: While performance matters most, a bike your daughter loves the look of will motivate her to ride more often. CT Bikes stocks everything from classic pink and purple to bold multicolor designs.

Weight: Girls, especially younger ones, often struggle with heavier bikes. Look for lightweight alloy frames under 10kg wherever possible.

Brake Levers: Smaller hands need smaller brake levers. Check that your daughter can comfortably reach and squeeze the brakes without stretching.

Best Girls Bikes at CT Bikes:

• Viking Sparkle 12″ — ideal for little girls aged 2–4
• Viking Angel 16″ — perfect for girls aged 4–6
• Viking Enchanted 14″ — great for girls aged 3–5
• RoyalBaby Girls’ Button Freestyle Bike 16″ — a stylish, fun freestyle bike available at just £89.99
• Huffy Glimmer Girls Bike 16 Inch — a premium quality American brand delivering a smooth, comfortable ride for girls aged 5–7
• Elswick Eternity 24 Inch Girls Bike — the top pick for older girls aged 8–12, with 6 speeds and a stunning blue and pink design

4. Children’s Bike for Boys: What to Look For

Boys’ bikes tend to feature a traditional diamond or mountain-style frame with a higher top tube. They’re built for durability and often feature bolder, more aggressive styling. With that in mind, here are the key considerations for boys’ bikes:

Key Considerations for Boys Bikes:

Durability: Boys tend to be harder on their bikes — jumping curbs, riding off-road, and generally testing limits! Look for a sturdy steel or alloy frame that can take some punishment.

Suspension: For boys who enjoy off-road riding, a bike with front suspension (or full suspension) will handle bumps much better and provide a more comfortable ride.

Gears: Boys often want more speed and versatility. A 6-speed or 7-speed geared bike gives them the flexibility to tackle hills and longer rides with ease.

Style: Bold colors, aggressive designs, and sporty looks tend to appeal to boys. CT Bikes stocks bikes in everything from classic red to bold orange.

Best Boys Bikes at CT Bikes:

• Viking Monster 14″ — a tough, fun bike for boys aged 3–5
• Falcon Cobalt 20″ Full Suspension — brilliant for adventurous boys aged 6–9 who love off-road riding
• Tiger Warrior 20″ Orange — a bold, eye-catching bike that boys will be proud to ride

5. Types of Children’s Bikes Explained

Understanding the different types of kids bikes available will help you choose the best option for your child’s riding style and environment. With that in mind, here’s a simple breakdown of the main options:

Balance Bikes

Balance bikes have no pedals. Children sit on the saddle and use their feet to push along the ground. This teaches balance and steering naturally, making the transition to a pedal bike much faster and easier. Choose one for children aged 18 months to 4 years.

Single Speed Pedal Bikes

The most common type for younger children, usually ages 3–7. Simple, lightweight, and easy to ride — just pedal and go. Choose one if your child is ready for a straightforward first pedal bike; they can often be used with stabilizers at first and without them as confidence builds.

Geared Kids Bikes

From around age 6 onwards, children can benefit from geared bikes. Multiple speeds allow riders to tackle hills, longer distances, and varied terrain with much less effort. Perfect for school-age children and juniors.

Children’s Mountain Bikes

Built for off-road adventures, kids mountain bikes feature wider tyres, suspension forks, and sturdy frames. Ideal for children who love exploring trails, parks, and rough terrain.

Children’s BMX Bikes

BMX bikes are compact, tough, and designed for tricks, stunts, and skate park riding. They typically have 20-inch wheels, a single speed, and a very strong frame. Great for children aged 7 and above who love action sports.

Children’s Electric Bikes

A growing trend in the UK, electric kids bikes provide pedal assistance to help children tackle hills and longer distances with less effort. They’re safe, fun, and increasingly popular. Check out CT Bikes’ range of children’s electric bikes for the latest options.

6. Essential Children’s Bike Accessories

Once you’ve chosen the perfect bike, don’t forget the essential accessories that keep your child safe and make riding even more enjoyable.

🪖 Bike Helmet (Essential)

A properly fitted helmet is non-negotiable. It should sit flat on the head, cover the forehead, and fasten snugly under the chin. Look for helmets that meet EN1078 safety standards. CT Bikes stocks a full range of children’s bike helmets in various sizes and styles.

💡 Bike Lights

If your child rides in low light conditions — early mornings, evenings, or during winter — front and rear lights are essential for visibility and legal compliance in the UK.

🔔 Bike Bell

A classic accessory that’s also a legal requirement in some circumstances. A fun bell gives young riders a sense of ownership over their bike and helps alert pedestrians.

🧤 Cycling Gloves

Gloves protect little hands in case of falls and improve grip on the handlebars. Great for off-road riding in particular.

🛡️ Stabilisers

For beginners, stabilizers provide essential support. Choose ones that are easy to remove so you can take them off when your child is ready.

🎒 Bike Basket

A bike basket adds practicality and fun — children love being able to carry their toys, snacks, or school bags on their bike.

7. Safety Tips for Young Cyclists

Keeping your child safe on their bike should always be the top priority. Here are our top safety tips for young riders:

• Always wear a helmet — every single ride, no exceptions.
• Check the brakes before every ride to make sure they’re working properly.
• Adjust the saddle height so your child can comfortably touch the ground.
• Start in a safe, open space — a quiet car park, playground, or garden is ideal for beginners.
• Teach road safety basics — stopping at junctions, looking both ways, using hand signals.
• Use high-visibility clothing — especially during autumn and winter months.
• Fit lights and reflectors if riding near roads or in low-light conditions.
• Supervise young children at all times near roads or traffic.
• Check the bike regularly — tyres, brakes, chain, and saddle should all be checked monthly.

8. How to Teach Your Child to Ride a Bike

Learning to ride a bike is a huge milestone — and with the right approach, it doesn’t have to be stressful for you or your child. Here’s a simple step-by-step method:

Step 1: Start with a balance bike or remove the pedals

Before introducing pedaling, let your child get comfortable with balancing and steering. Either use a balance bike or temporarily remove the pedals from their regular bike.

Step 2: Find the right environment

Choose a flat, open, quiet space — ideally with a slight downhill gradient to help them gain momentum naturally. A smooth tarmac surface is ideal.

Step 3: Adjust the saddle correctly

The saddle should be low enough for both feet to rest flat on the ground. This gives maximum confidence and control.

Step 4: Let them glide

Encourage your child to sit on the saddle, push off with their feet, and glide. Once they’re comfortable lifting their feet for a few seconds at a time, they’re ready for the next step.

Step 5: Introduce pedaling

Reattach the pedals and show your child how to start pedaling from a stationary position. Hold the back of the saddle (not the child!) for initial support if needed.

Step 6: Practice braking

Make sure your child knows how to use the brakes confidently before riding independently. Practice stopping from slow speeds first, then gradually increase.

Step 7: Celebrate every milestone

Learning to ride a bike takes time and patience. Celebrate every small achievement — from their first glide to their first independent ride!
