LittleBig vs Decathlon BTwin 2-in-1: Which Balance Bike Is Better?

Both LittleBig and the Decathlon BTwin 2-in-1 let children learn to balance before moving onto pedals. But there's a big difference in how they ride, how they fit and how long they'll last.

Decathlon offers an affordable way to get started. LittleBig takes a different approach, with a lighter aluminium frame, a wider fit range and three stages of riding.

Here's what I'd look at before deciding between them.

LittleBig vs Decathlon BTwin 2-in-1: At a Glance

Weight: Why 2.3kg Makes a Big Difference

LittleBig: 4.3kg in balance mode, 6.2kg with pedals.

Decathlon: 6.6kg in balance mode.

When you're two or three years old, the weight of your bike makes a huge difference.

At 6.6kg, the Decathlon is over 50% heavier than LittleBig in balance mode. Much of that difference comes from its steel frame and permanently attached drivetrain.

I've always felt that a child's first bike should be as easy to handle as possible. A lighter bike takes less effort to push, steer and pick up after a wobble. That gives little riders more freedom to concentrate on learning to balance.

Saddle Height: It's About Fit, Not Just Age

LittleBig: 32-54cm saddle height range.

Decathlon: 41.5-52.5cm saddle height range.

This is one of the biggest differences between the two bikes.

Both reach a similar maximum saddle height, but LittleBig starts almost 10cm lower. That's important because children need to reach the ground comfortably with both feet when learning to balance.

LittleBig's growing frame also provides a much wider adjustment range, allowing children to start younger and continue riding as they grow.

Rather than choosing a bike based on age alone, I'd always recommend checking your child's inside leg measurement against the saddle height.

Frame, Brakes and Component Quality

There's more to a good balance bike than its weight and saddle height.

LittleBig uses a lightweight 6061 aluminium frame and fork, while Decathlon uses steel. Aluminium helps keep weight down and resists corrosion.

Brakes are another important consideration. LittleBig has front and rear child-sized hand brakes, so children can practise controlling their speed from their earliest rides.

And when they're ready for pedals, those same brakes are already familiar. There's no need to learn a different braking technique.

I've always believed that children benefit from learning these skills early, rather than having to start again when they move onto a pedal bike.

You can read more about this in our guide to balance bikes with brakes.

Balance to Pedals: Two Stages or Three?

Both bikes are designed to help children progress from balancing to pedalling, but they take different approaches.

Decathlon converts from a balance bike into a pedal bike.

LittleBig has three stages. It starts as a little balance bike, grows into a bigger balance bike by flipping the frame, then converts into a pedal bike using the optional pedal kit.

That extra balance stage is important. Not every child is ready for pedals at the same age, and there's no reason to rush them.

With LittleBig, children can keep developing their balance and confidence on the same familiar bike until they're ready to pedal.

Price vs Long-Term Value

There's no getting around it - LittleBig costs more upfront than the Decathlon.

And if you're simply looking for the lowest-cost way to get your child started, Decathlon is worth considering.

But I'd also think about how long the bike will last and how enjoyable it will be for your child to ride.

LittleBig's lighter frame, wider saddle adjustment and three-stage design mean it can take a child from their first balancing attempts through to independent pedalling.

Rather than buying a balance bike and then replacing it as your child grows, you're investing in one bike designed to cover several years of riding.

That's where I believe LittleBig offers its greatest value.

Which Would I Choose?

If keeping the initial cost down is your main priority, and your child already fits the Decathlon comfortably, it's a reasonable option.

But if you want a lighter bike, a lower starting saddle height, proper hand brakes and more room to grow, I'd choose LittleBig.

Those are exactly the things I focused on when designing it. I wanted children to have a bike that was easy to learn on, enjoyable to ride and capable of growing with them - without having to start over on a different bike.

And for me, that's what makes a great first bike.
