LittleBig vs Decathlon Btwin 2 in 1 Balance to Pedal Bike Comparison
Bottom Line Up Front
LittleBig and the Decathlon Btwin 2 in 1 both convert from balance to pedal, but they are built to very different standards. The Decathlon focuses on entry price. LittleBig focuses on weight, range of fit, and long-term durability. If you want the lightest possible balance mode, the lowest starting saddle height, higher-grade components and a bike that lasts through multiple growth stages, LittleBig is the stronger long-term choice.

This comparison reviews the LittleBig 3 in 1 convertible balance bike against the Decathlon Btwin 2 in 1, focusing on weight, fit range, materials and real-world usability.
Weight
Decathlon 2 in 1: 6.6kg in balance configuration.
LittleBig: 4.3kg in balance mode and 6.2kg in pedal mode.
Because the Decathlon uses a steel frame and keeps the drivetrain permanently attached, its balance configuration is significantly heavier. At 4.3kg, LittleBig is almost 50 percent lighter in balance mode. That difference matters for small riders. A lighter bike is easier to push, steer, control and lift. It also means less effort for parents carrying it home.
If you want to understand why weight is critical in early riding development, our article on why a balance bike with pedals can be ideal explains the progression in detail.
Saddle Height Range
Decathlon: 41.5cm to 52.5cm (11cm adjustment).
LittleBig: 30cm to 52cm (22cm adjustment).
Both bikes reach a similar maximum height, but LittleBig starts much lower. That 30cm minimum saddle height allows children to begin earlier and progress confidently. With double the adjustment range, LittleBig fits for significantly longer, often covering multiple years of riding.
For help choosing the correct size, see our balance bike age range guide.
Frame and Component Quality
The Decathlon is built to a price point with a steel frame, plastic brake levers and simplified cockpit. LittleBig uses an aluminium frame and fork with alloy components throughout. Aluminium is lighter, rust-resistant and more durable over time.
Brake consistency also matters. LittleBig uses dual child-specific hand brakes in both balance and pedal modes, maintaining skill continuity. You can read more about the importance of braking development in our guide to balance bikes with brakes.
Long-Term Value
Although the upfront price of LittleBig is higher, the long-term value is significantly stronger:
- Much lighter in balance mode.
- Twice the saddle adjustment range.
- Aluminium frame and higher-grade components.
- Designed to last through multiple developmental stages.
When you factor in lifespan and ride quality, LittleBig is designed as a long-term solution rather than a short-term stepping stone.
Comparison at a Glance
| Feature | LittleBig | Decathlon 2 in 1 | Why It Matters |
|---|---|---|---|
| Weight (Balance Mode) | 4.3kg | 6.6kg | Lighter bikes are easier to balance, steer and control. |
| Frame Material | Aluminium | Steel | Aluminium reduces weight and resists corrosion. |
| Saddle Height Range | 30cm - 52cm | 41.5cm - 52.5cm | Lower start height means earlier entry and longer lifespan. |
| Brake Setup | Dual hand brakes in all modes | Single configuration | Consistent braking improves skill development. |
| Overall Value | Long lifespan, premium components | Lower entry price | Long-term use typically offsets higher initial cost. |
Is the Decathlon 2 in 1 Balance Bike Worth It?
The Decathlon Btwin 2 in 1 is a budget-friendly option for parents who want a simple balance to pedal conversion without a high upfront cost. It performs adequately for short-term use, particularly for children already close to pedal readiness. However, its heavier steel frame, higher minimum saddle height, and shorter adjustment range mean it typically fits for less time and can feel more difficult to handle for smaller riders. If your priority is lowest initial price, the Decathlon may meet that need. If your priority is lighter weight, earlier starting fit, longer usable lifespan and higher-quality components, the LittleBig offers stronger long-term value.
Who Each Bike Suits
Decathlon Btwin 2 in 1: Suitable for families prioritising lowest upfront cost and short-term use.
LittleBig: Suited to families wanting lower starting saddle height, lighter balance mode, stronger components and a bike designed to last for years.
Final Verdict
Both bikes convert from balance to pedal, but they are built with different priorities. The Decathlon focuses on affordability. LittleBig focuses on weight, fit range, component quality and longevity. If you want a bike that supports skill development from the earliest stage and lasts through multiple growth phases, LittleBig is the stronger long-term investment.
