Complete Your LittleBig
A little bike packed with brilliant design. I love the idea that one bike can accompany my child on his entire learn-to-ride journey, before being passed on to siblings or friends. It has a great design, so I am sure the LittleBig will last.
One of the most adjustable kids bikes ever. Extremely light for a kids bike. Buy it once and it lasts quite a few years. An excellent, excellent bike. It’s proven to be a product that I still use all the time.
The LittleBig easily guides your mini-shredder through their exciting journey from balance bike to pedal powered adventures.
This cool machine makes a lot of sense: great convertible geometry, excellent part spec and amazing build quality offers tremendous value

The LittleBig bike is a brilliant concept that will see your child travel from the early stages of balance through to learning how to pedal and beyond. It's light, well made and above all so exciting to ride that you'll struggle to get them off it.

LittleBig sizing at a glance
Not sure? Inside leg is the best way to check fit.
- With your child wearing their shoes, stand them with their back against a wall.
- Place a book between their legs and gently raise it until it's snug.
- Measure from the top of the book straight down to the floor.
If the measurement is between 33cm and 54cm (13–21"), the LittleBig will fit.
Once your child can confidently balance, steer and coast along with their feet off the ground, they’re ready to try pedals.
There’s no need to rush. Let them build confidence on the balance bike first, then add the Pedal Kit when they’re ready. Because they’re learning to pedal on the same familiar bike, the transition is usually much easier.
Ideally, they should be able to:
- Coast comfortably with their feet off the ground
- Make controlled turns
- Use the bike’s brakes confidently
- Have enough strength to turn the pedals.

Why We Built the LittleBig
LittleBig Bikes was founded by Simon Evans - a parent, engineer, round-the-world cyclist and mountain biker - with one clear goal: to help kids learn to ride with confidence
After seeing how quickly traditional kids bikes are outgrown and discarded, Simon set out to create a bike that adapts as children develop their skills. The LittleBig starts as a balance bike and later converts to a pedal bike on the same familiar frame, supporting years of confident riding.
Thoughtfully engineered and built to last, LittleBig reduces waste while offering long-term value for families who want a more sustainable approach to learning on two wheels.
