Woom GO 2 vs Frog 38 vs LittleBig: 14 Inch Kids Bike Comparison

Quick Verdict

Woom GO 2, Frog 38 and LittleBig are all lightweight, high-quality 14 inch kids bikes, but they are designed for different stages of learning to ride.

Woom GO 2 and Frog 38 are dedicated pedal bikes for children who are ready to start pedalling. LittleBig takes a different approach. It begins as a balance bike, grows into a larger balance bike and then converts into a full 14 inch pedal bike using the same frame.

If your child is already confidently pedalling, Woom GO 2 and Frog 38 are both excellent choices. If your child is still learning to balance, or you want one bike that grows with them from balance to pedals, LittleBig offers a wider range of use.

This comparison looks at weight, saddle height, brakes, geometry, components and long-term cost to help you decide which bike best suits your child.

Which 14 Inch Kids Bike Is Better for Your Child?

The best choice depends on your child's size, confidence and riding experience.

Woom GO 2 is an excellent option for children who are ready for a lightweight first pedal bike. Its low weight and child-specific components make it easy for smaller riders to handle.

Frog 38 is another strong choice for children who are ready to pedal. It offers quality components, child-specific geometry and front and rear hand brakes.

LittleBig is particularly useful for children who are still learning to balance. It starts as a lightweight balance bike and can be adjusted as children grow, before adding the optional pedal kit when they're ready.

Rather than moving from one bike to another, children can develop their balance, steering and braking skills on the same familiar bike before learning to pedal.

What All Three Bikes Do Well

Lightweight Design

All three bikes are designed to be lightweight and manageable for young riders. Low weight makes a bike easier to start, stop, steer and pick up, particularly when children are developing confidence.

Child-Specific Components

Woom, Frog and LittleBig all use components designed around smaller riders, including appropriately sized contact points, child-friendly controls and geometry suited to young children.

Designed for Early Riders

Woom GO 2 and Frog 38 are dedicated first pedal bikes. LittleBig can also be used as a first pedal bike, but allows children to develop their balance and braking skills before pedals are introduced.

Weight Comparison

Weight is one of the most important considerations when choosing a child's bike. A lighter bike is easier to control, particularly when starting, stopping and learning new skills.

Woom GO 2: approximately 5.1-5.5 kg.

Frog 38: approximately 6.4 kg.

LittleBig: 4.3 kg in balance mode and 6.2 kg in pedal mode.

Woom GO 2 is the lightest dedicated pedal bike in this comparison. That is a genuine advantage for children who are already ready to pedal.

Frog 38 and LittleBig are very similar in pedal-bike weight. However, LittleBig can also be used as a 4.3 kg balance bike, allowing children to begin riding on a lighter setup before the pedals are added.

For families starting with a child who is still learning to balance, that difference is particularly relevant.

Saddle Height and Size Range

A bike's fit is often more important than its recommended age range. Children need to feel comfortable reaching the handlebars and placing their feet on the ground, particularly when they are first learning to ride.

The biggest difference is LittleBig's lower starting saddle height. At approximately 32 cm in its smallest balance-bike configuration, it can accommodate children who are not yet tall enough for a dedicated 14 inch pedal bike.

As children grow, LittleBig can be converted into its larger balance-bike configuration and eventually into a pedal bike. Its overall adjustment range is wider than either Frog 38 or Woom GO 2.

It's important to distinguish the overall range from the pedal-bike fit. LittleBig's lower saddle positions are used in balance mode, while its pedal configuration is designed for larger children.

For help choosing the correct size, see our balance bike age and sizing guide.

Brakes and Learning Progression

All three bikes use braking systems designed for young riders, but LittleBig introduces hand braking at an earlier stage.

LittleBig includes front and rear child-specific hand brakes in little balance, big balance and pedal modes. Children can become familiar with braking before learning to pedal.

Frog 38 uses front and rear hand brakes designed for smaller hands, providing reliable braking control for children learning to ride independently.

Woom GO 2 also uses child-specific braking components. European and UK versions have front and rear hand brakes, although configurations may vary between markets.

The main advantage of LittleBig is continuity. When the pedals are added, the child keeps using the same brake levers and braking technique they already know.

Components and Ride Quality

Woom GO 2

• Very lightweight construction.
• High-quality child-specific components.
• Narrow Q-factor cranks designed for young riders.
• Premium finish and strong resale appeal.

Frog 38

• Well-established children's bike brand.
• Child-specific geometry and components.
• Front and rear hand brakes.
• Quality construction designed for regular riding.

LittleBig

• 6061 aluminium frame and fork.
• Cartridge-bearing wheels and headset.
• 14 inch air-filled tyres.
• Front and rear hand brakes in every mode.
• Three riding configurations using the same frame.
• Lifetime warranty on the frame and fork.

All three bikes offer quality components. The key difference is that Woom and Frog are optimised as dedicated pedal bikes, while LittleBig is designed to work across both balance and pedal-bike stages.

Geometry and Fit Comparison

Bike geometry influences stability, steering and riding position. Although these measurements are useful, the most important consideration for parents is whether the bike fits their child comfortably.

Woom GO 2 and Frog 38 have geometry designed specifically around young pedal-bike riders. LittleBig uses a different frame configuration for its smaller balance-bike stage before converting into a larger balance bike and pedal bike.

For most families, the practical differences are the starting fit, overall adjustment range and whether the bike can be used before a child is ready to pedal.

Price and Long-Term Value

Woom GO 2 and Frog 38 are premium children's pedal bikes. If your child is already confidently pedalling, either can be an excellent investment.

However, if your child still needs a balance bike, it's worth considering the combined cost of purchasing a balance bike and then a separate pedal bike.

Based on these listed prices, LittleBig offers a lower combined purchase cost than buying the equivalent Woom or Frog balance-bike and pedal-bike combinations.

This comparison is most relevant for families starting with a child who still needs to learn balance. If your child is already confidently pedalling, the earlier balance-bike purchase may not be relevant.

LittleBig also offers the convenience of keeping the same familiar bike throughout the transition to pedals, rather than introducing an entirely new bike.

What Makes LittleBig Different?

One Bike That Grows With Your Child

LittleBig is designed to cover three stages of riding. It begins as a small balance bike, converts into a larger balance bike and then becomes a 14 inch pedal bike with the optional pedal kit.

This gives children a wider range of use without needing to replace the frame as their riding skills develop.

Learn to Pedal on a Familiar Bike

When children are ready for pedals, they already know how their LittleBig steers, balances and brakes. Adding the pedal kit introduces pedalling without requiring them to adjust to an entirely different bike.

That familiarity can help make the transition to independent pedalling more straightforward.

Lifetime Frame and Fork Warranty

LittleBig includes a lifetime warranty on its aluminium frame and fork, alongside a two-year warranty on components.

Designed and Assembled in Ireland

LittleBig was developed around the idea that children should be able to learn balance first and progress to pedals when they're ready. Each bike is assembled in Ireland before dispatch.

Frequently Asked Questions

Which bike is best for building confidence?

All three bikes are designed to be manageable for young riders. LittleBig allows children to develop balance and braking skills before pedals are added, while Woom GO 2 and Frog 38 are designed for children who are ready to begin pedalling.

Can LittleBig be used as a balance bike?

Yes. LittleBig begins as a small balance bike, converts into a larger balance bike and then becomes a 14 inch pedal bike using the optional pedal kit.

Which bike has the widest size range?

LittleBig has the widest overall saddle-height range in this comparison, covering approximately 32-54 cm across its different configurations. Woom GO 2 and Frog 38 are dedicated pedal bikes with narrower adjustment ranges.

Can Woom GO 2 or Frog 38 be used as balance bikes?

Both are designed as pedal bikes rather than convertible balance bikes. Children would normally develop their balance skills on a separate balance bike before progressing to either model.

Which bike is best for a 3 or 4 year old?

It depends on the child's height, inside leg measurement and riding ability. If they're already confidently pedalling, Woom GO 2 or Frog 38 may be suitable. If they're still learning balance, LittleBig allows them to develop those skills before adding pedals.

Which offers the best long-term value?

For families beginning with a balance bike, LittleBig can offer better long-term value because it covers multiple riding stages on the same frame. For children who are already ready for a pedal bike, Woom GO 2 and Frog 38 are both strong alternatives.
