LittleBig reviews from parents
With a low step-through frame and adjustable seat and handlebars, your toddler can easily touch the ground and feel secure at every stage. This design encourages balance and control without the need for training wheels.
One bike that adapts as your child grows. The LittleBig starts as a balance bike for toddlers, then easily converts to a larger balance bike and finally a proper pedal bike — extending its life and saving you from buying multiple bikes along the way.
Built from lightweight, high-quality materials, the LittleBig is easy for kids to propel and steer and for parents to carry. A lighter bike means longer, happier rides and faster learning.
When they’re ready, simply add the pedals and let them take off — no stabilisers or complicated adjustments needed. The clever 3 in 1 design supports a natural, seamless move from gliding to pedalling.
Hand assembled in Ireland with durable components and thoughtful engineering, LittleBig bikes are built to last through years of adventures — and even to be passed down to siblings or friends. We back all this up by offering a lifetime warranty!
From a perfectly proportioned cockpit to soft grips and a comfy saddle, every detail is designed to keep kids smiling and wanting to ride again and again.
Designed by parents who wanted a smarter way to help children learn to ride. Read more about our story and approach on our About Us page.
Instead of buying separate balance and pedal bikes as your child grows, the LittleBig bike does it all — saving you money (and storage space) in the long run. Its clever, convertible design means you get three bikes in one, without compromising on quality or fit.
Expert Reviews of the LittleBig Toddler Bike
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.

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.
One balance bike that converts to pedals
The LittleBig grows from a big balance bike into a big pedal bike. When your little one is ready to begin pedalling, just add the pedal kit and off they go!
Having learned to balance first, your child’s transition to pedalling will be easy, and usually only takes a few short goes.
Lightweight Balance Bike for Easy Control
The LittleBig frame and fork are made from 6061-T6 aluminium which is commonly used in road and mountain bikes due to its light weight and durability.
Lightweight balance bikes are easier to push, steer, brake and lift which will help your child cycle with confidence.

The LittleBigs 14 inch wheels gives a stable ride and glides over a range of terrain with ease. Forest trails, school rides, BMX track, pump track, with these tyres, your toddler can ride anywhere!
The air-filled rubber tires are comfortable and grippy while still being durable and long lasting. The lightweight alloy rims roll on sealed cartridge bearings which are quiet and will run smoothly for years.
Premium spec kids bike built to last for years
LittleBig is hand-assembled in Ireland with kids specific parts, including a lightweight saddle, alloy riser handlebar and forged alloy style stem. These are all adjustable to ensure a perfect fit, so your child can push their limits and explore new adventures.

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.
