Woom vs Frog vs LittleBig: Which Is the Best 14 Inch Kids Bike?

Woom GO 2, Frog 38 and LittleBig are all lightweight premium children's bikes designed to help young riders develop confidence and ride independently. The key difference is that Woom GO 2 and Frog 38 are dedicated 14 inch pedal bikes, while LittleBig starts as a balance bike, grows into a larger balance bike, and then converts into a full 14 inch pedal bike on the same frame.

If your child is already confidently pedalling and you simply want a lightweight 14 inch bike, Frog 38 and Woom GO 2 are both excellent options. If you want one bike that can cover the balance bike and pedal bike stages while offering a wider fit range and longer useful lifespan, LittleBig provides a more versatile solution.

Which Is the Best 14 Inch Kids Bike?

If your child is already ready for a dedicated 14 inch pedal bike, both the Frog 38 and Woom GO 2 are excellent lightweight options with strong reputations among cycling families.

LittleBig competes directly in the same 14 inch category, but offers something fundamentally different. Rather than starting with a dedicated pedal bike, it allows children to begin in balance mode, progress to a larger balance bike, and then convert to pedals on the same familiar frame.

This wider progression means many children can start earlier, develop balance skills for longer and move to pedals without changing bike geometry, controls or fit.

For families focused on long-term value, versatility and minimising the number of bikes purchased, LittleBig is often the strongest overall option. For families whose child is already confidently pedalling and simply needs a lightweight 14 inch pedal bike, Frog and Woom remain excellent benchmarks.

What All Three Bikes Do Well

Lightweight Design

All three bikes prioritise low weight and child-friendly handling. Lightweight bikes are easier for children to control, manoeuvre and recover when balance is lost.

Child-Specific Components

Each bike uses appropriately sized contact points, short-reach brake levers and geometry designed specifically around young riders rather than scaled-down adult bicycles.

Designed for Early Riders

Woom GO 2 and Frog 38 are designed as first pedal bikes. LittleBig can also function as a first pedal bike, but additionally allows children to learn balance on the same platform before pedals are introduced.

Weight Comparison

Weight is one of the most important factors when choosing a children's bike. A lighter bike is easier to start, stop, steer and pick up after a fall.

Woom GO 2: 5.1-5.5kg

Frog 38: 6.4kg

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

Woom GO 2 is the lightest dedicated 14 inch pedal bike in this comparison. Frog 38 and LittleBig pedal mode are very similar in weight. However, because LittleBig can also be used as a 4.3kg balance bike, many children begin their riding journey on a significantly lighter platform before pedals are added.

Fit and Saddle Height Range

Fit is often more important than weight. Children learn fastest when they can comfortably place both feet on the ground and reach the handlebars naturally.

The biggest difference is starting height. LittleBig starts considerably lower than either Frog 38 or Woom GO 2, allowing many children to begin riding earlier.

Woom and Frog focus on the dedicated pedal bike stage. LittleBig spans the balance bike stage, larger balance bike stage and pedal bike stage, creating a wider overall fit range.

If you are unsure which size range is appropriate for your child, see our balance bike age range guide.

Brakes and Learning Progression

All three bikes use quality braking systems designed specifically for children.

LittleBig uses front and rear hand brakes throughout the entire riding journey. Children learn the same braking technique in little balance mode, big balance mode and pedal mode.

Frog 38 uses front and rear child-specific hand brakes and is widely regarded as one of the better braking setups in the children's bike market.

Woom GO 2 uses different brake configurations depending on market. European and UK models use front and rear hand brakes, while some markets include a coaster brake configuration.

Consistent hand braking can make the transition to larger bikes easier because the controls remain familiar throughout a child's riding progression.

Geometry and Fit Comparison (For the Detail-Oriented!)

Geometry influences stability, steering speed and overall riding feel. While most parents will focus on fit and weight, geometry explains why bikes feel different on the trail or pavement.

In practical terms, all three bikes handle well. The more significant difference for most families is how long each bike fits and whether it can cover multiple developmental stages.

Balance Bike to Pedal Bike Cost Comparison

When comparing children's bikes, it's worth looking beyond the price of a single bike and considering the full journey from balance bike to pedal bike.

For families starting with a younger child, this can have a significant impact on overall cost and the number of transitions a child experiences while learning to ride.

Where LittleBig Competes Differently

Read Customer Reviews

One Platform That Starts Earlier and Lasts Longer

LittleBig is unique in this comparison because it functions as a balance bike, larger balance bike and 14 inch pedal bike on the same frame. Rather than moving between separate bikes as your child grows, the same platform evolves alongside them.

Transition to Pedals on the Same Bike

Because children already know the fit, steering and braking characteristics of the bike, the only major new skill they need to learn is pedalling. This can help make the transition smoother and more intuitive.

Lifetime Warranty

LittleBig includes a lifetime warranty on the frame and fork, comparing favourably with other premium children's bike brands.

Built and Assembled in Ireland

Every LittleBig is hand assembled in Ireland and designed specifically around the progression from balance bike to pedal bike.

Frequently Asked Questions

Which bike is best for building confidence?

All three bikes are designed for young riders, but LittleBig's lower starting fit and balance bike modes allow children to develop confidence and control before moving to pedals. Woom GO 2 and Frog 38 are excellent dedicated pedal bikes for children who are already ready to pedal independently.

Can LittleBig be used as a balance bike?

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

Which bike lasts the longest?

LittleBig covers the widest age and size range because it spans multiple riding stages. Frog 38 and Woom GO 2 are dedicated 14 inch pedal bikes designed for a shorter portion of a child's development.

Do Frog 38 and Woom GO 2 convert to pedal bikes?

No. Both are dedicated pedal bikes. Children normally move onto them after learning balance on a separate balance bike.

Which offers the best long-term value?

For families starting with a younger child, LittleBig often provides the best long-term value because one bike can cover multiple stages that would otherwise require separate purchases.

Final Verdict

Woom GO 2, Frog 38 and LittleBig are all excellent children's bikes, but they solve slightly different problems.

If your child is already confidently pedalling and you want a dedicated 14 inch pedal bike, Woom GO 2 and Frog 38 remain among the best options available. Both are lightweight, well-designed and built specifically for young riders.

If you want one bike that can start earlier, cover the balance bike stage, grow with your child and eventually become a full 14 inch pedal bike, LittleBig offers a broader developmental range and stronger long-term value.

For many families, the biggest advantage is not simply saving money, but allowing children to progress through multiple riding stages on one familiar bike.
