Guardian 14 vs Woom GO 2 vs LittleBig: Kids Bike Comparison

Quick Verdict

Guardian 14, Woom GO 2 and LittleBig are all designed for young children, but they offer different approaches to learning to ride.

Guardian 14 and Woom GO 2 are dedicated 14 inch pedal bikes. Guardian focuses on simple braking through its SureStop system, while Woom prioritises low weight and child-specific components.

LittleBig also converts into a full 14 inch pedal bike, but begins as a balance bike and grows with your child before pedals are added.

If your child is already confidently pedalling, Guardian and Woom are both strong choices. If your child is still learning to balance, or you want one bike that covers the progression from balance to pedals, LittleBig offers greater versatility.

This comparison looks at the LittleBig convertible balance bike, Guardian 14 and Woom GO 2, including weight, fit, braking systems, components and long-term value.

Guardian 14 vs Woom GO 2 vs LittleBig: Specifications

Which 14 Inch Kids Bike Is Better for Your Child?

The best choice depends on your child's size, confidence and whether they're already ready to pedal.

Guardian 14 is designed for children learning to ride a pedal bike. Its SureStop braking system allows both brakes to be operated through one hand lever, simplifying braking for younger riders.

Woom GO 2 is a particularly lightweight 14 inch pedal bike. Its child-specific components and low weight make it a strong option for smaller children who are ready to start pedalling.

LittleBig is designed for children who may not be ready for pedals yet. It begins as a balance bike, grows into a larger balance bike and converts into a pedal bike when the child is ready.

Rather than moving to a completely different bike, children can develop their balance, steering and braking skills on the same familiar frame before learning to pedal.

What All Three Bikes Do Well

Designed for Young Riders

All three bikes use child-focused geometry and components designed to make riding more manageable for smaller children.

Braking Systems for Children

Each bike has a braking system designed around young riders. Guardian uses its SureStop system, Woom uses child-specific brakes, and LittleBig includes front and rear hand brakes throughout its balance and pedal configurations.

For more information about developing braking skills, read our guide to balance bikes with brakes.

Designed for Learning to Pedal

Guardian 14 and Woom GO 2 are dedicated first pedal bikes. LittleBig also functions as a first pedal bike, but allows children to develop their balance and braking skills before pedals are introduced.

Weight Comparison

Weight makes a significant difference to how easily children can start, stop, steer and manoeuvre a bike.

Guardian 14: approximately 7.3 kg with pedals and kickstand.

Woom GO 2: approximately 5.1-5.5 kg.

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

Woom GO 2 is the lightest pedal bike in this comparison, making it particularly appealing for smaller children who are ready to pedal.

LittleBig weighs approximately 1.1 kg less than Guardian 14 in pedal mode, based on the listed weights. In balance mode, LittleBig weighs just 4.3 kg, allowing children to develop their skills on a lighter bike before adding pedals.

Guardian is the heaviest of the three, although its braking system may be a consideration for families prioritising simple brake operation.

Saddle Height and Size Range

Choosing the correct size is one of the most important parts of buying a child's bike. Children need to reach the handlebars comfortably and have sufficient control when starting and stopping.

LittleBig has the lowest starting saddle height in this comparison. 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 converts into its larger balance-bike configuration and eventually into a pedal bike.

Guardian has a higher maximum saddle height, while Woom GO 2 is designed around a narrower range of smaller pedal-bike riders. LittleBig's main advantage is that its configurations cover both the balance and pedal stages.

For more information on choosing the correct size, see our balance bike age and sizing guide.

Brakes: Guardian SureStop vs Woom vs LittleBig

One of the most interesting differences between these bikes is how their braking systems work.

Guardian SureStop Braking System

Guardian uses its SureStop braking system, which operates both brakes through a single hand lever. This is designed to simplify braking and help children avoid applying too much front braking force.

It is a distinctive feature of Guardian bikes and may appeal to parents who want a straightforward braking system for a child learning to pedal.

Woom GO 2 Brakes

Woom GO 2 uses child-specific braking components designed for smaller hands. European and UK models have front and rear hand brakes, although specifications may vary by market.

LittleBig Front and Rear Hand Brakes

LittleBig uses separate front and rear hand brakes in all three configurations.

Children can learn how to operate their brakes while riding in balance mode, before the pedal kit is fitted. When they begin pedalling, the braking controls remain exactly the same.

This consistency allows children to build braking confidence alongside their balance and steering skills.

Components and Ride Quality

Guardian 14

• SureStop braking system operated through one lever.
• Child-specific geometry and components.
• 14 inch wheels.
• Designed as a dedicated first pedal bike.

Woom GO 2

• Very lightweight construction.
• Child-specific frame geometry.
• Components designed for smaller hands and feet.
• Premium finish and lightweight pedal-bike design.

All three offer features designed to support young riders. The key difference is that Guardian and Woom are dedicated pedal bikes, while LittleBig is designed to work across both balance and pedal-bike stages.

What Makes LittleBig Different?

One Bike That Grows With Your Child

LittleBig begins as a small balance bike, converts into a larger balance bike and then becomes a 14 inch pedal bike.

This allows children to progress through different riding stages without replacing the bike as their skills develop.

Lower Starting Saddle Height

LittleBig's overall saddle height range is 32-54 cm across its different configurations. Its lower starting height allows many children to begin learning balance before they're tall enough for a dedicated pedal bike.

Learn to Pedal on a Familiar Bike

When the optional pedal kit is added, children already know how their LittleBig steers, balances and brakes.

Instead of adjusting to an entirely new bike, they can focus on learning the additional skill of pedalling.

For more information about this approach, read our guide to balance bikes that convert to pedals.

Lifetime Frame and Fork Warranty

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

Balance Bike to Pedal Bike Cost Comparison

When comparing children's bikes, it's worth considering whether your child needs a balance bike first or is already ready for pedals.

For families beginning with a child who still needs to learn balance, LittleBig can reduce the need to purchase two separate bikes.

However, if your child is already confidently pedalling, the earlier balance-bike stage may not be relevant. In that situation, Guardian 14 and Woom GO 2 are both strong standalone options.

Because Guardian is priced in US dollars while the other examples are shown in euros, these figures should not be treated as a direct like-for-like price comparison.
