Strider 12 Sport vs LittleBig 3-in-1 | Balance Bike Comparison
Bottom Line Up Front
The well known Strider 12 Sport is a lightweight, simple 12 inch balance bike designed for very young riders. The LittleBig starts as a balance bike too, but uniquely grows into a bigger balance bike and then converts into a full 14 inch pedal bike on the same frame. If you want a short-term, balance-only starter, Strider works well. If you want one bike that carries your child from first strides through confident pedalling without replacing the frame, LittleBig offers greater longevity, better components, and stronger long-term value.

This comparison reviews the LittleBig 3 in 1 convertible balance bike alongside the Strider 12 Sport, focusing on weight, components, geometry and progression to pedals.
What Both Bikes Do Well
- Confidence-first fit with kid-sized contact points.
- Quick saddle height adjustment for growing riders.
- Encourage balance-first development, which is more effective than using stabilisers.
Features Comparison
| Feature | LittleBig | Strider 12 Sport |
|---|---|---|
| What it is | 3 in 1: little balance → bigger balance → 14 inch pedal bike | 12 inch balance bike only |
| Wheel size and tyres | 14 inch alloy wheels with air tyres for grip and comfort | 12 inch moulded wheels with flat-free foam tyres |
| Brakes | Front and rear child-specific hand brakes in all modes | No brakes |
| Frame and fork | 6061 aluminium frame and fork | Steel frame and fork |
| Weight | 4.3 kg (balance) • 6.2 kg (with pedals) | 3.0 kg (balance only) |
| Fit range intent | Approx. 2 to 6 years | Approx. 1 to 4 years |
| Conversion to pedals | Yes - add pedal kit to the same frame | No - separate pedal bike required |
| Warranty | Lifetime on frame and fork | 2 year limited |
Weight
The Strider 12 Sport is impressively light at 3.0 kg, making it easy for very young toddlers to push and carry. The LittleBig is slightly heavier in balance configuration at 4.3 kg, but that additional weight supports larger wheels, air tyres and a frame designed to convert into a pedal bike. For families wanting only an early balance bike, Strider’s low weight is appealing. For families wanting progression into pedals without replacing bikes, LittleBig offers broader functionality.
Saddle Height Range and Growth
Strider fits small riders early, but its adjustment range is limited to the balance stage. LittleBig starts low at 30 cm and extends up to 52 cm, spanning both balance and pedal configurations. This wider range allows it to cover significantly more growth. For help choosing the right fit, see our balance bike age range guide.
Braking and Skill Development
Strider does not include brakes. Children slow down with their feet. LittleBig includes front and rear child-specific hand brakes in all modes. Introducing braking before pedals can help build stronger control habits. If you want to understand why braking matters early, see our guide on balance bikes with brakes.
Components and Ride Quality
Strider keeps things simple with a steel frame and foam tyres. Foam tyres are maintenance-free but firmer and offer less grip on uneven ground. LittleBig uses an aluminium frame and fork, air-filled tyres and sealed cartridge bearings for smoother rolling and better surface grip. These differences become more noticeable as riding speed and confidence increase.
Long-Term Value
Buying a Strider covers the early balance phase. When your child is ready for pedals, you will need to purchase a separate 14 inch pedal bike. With LittleBig, the same frame converts into a pedal bike. This reduces cost over time and keeps geometry familiar. You can read more about this progression in our article on why a balance bike with pedals can be ideal.

Geometry Comparison
Fit and contact points determine how stable a bike feels and how long it remains usable.
| Geometry / Fit | LittleBig | Strider 12 Sport |
|---|---|---|
| Saddle height range (balance) | 30–52 cm | 28–43 cm |
| Saddle height range (pedal) | 37–52 cm | N/A |
| Tyre contact and ride feel | Air tyres absorb bumps and improve grip | Foam tyres are firmer with less traction |
| Growth adaptability | Frame grows and converts to pedals | Adjusts within balance stage only |
Who Each Bike Suits
Choose Strider 12 Sport if you want a very lightweight, simple entry into balance riding for toddlers and are comfortable purchasing a separate pedal bike later.
Choose LittleBig if you want higher-grade components, real braking development, larger wheels, and the convenience of converting the same bike into a 14 inch pedal bike when your child is ready.
Key Takeaway
The Strider 12 Sport is an excellent early-stage balance bike. The LittleBig is designed as a longer-term platform. For families who prefer one purchase that spans balance, braking and pedalling, LittleBig provides greater longevity and progression without replacing bikes.
