LittleBig reviews from parents
One thoughtful purchase carries your child from balance to confident pedalling and beyond. The LittleBig’s convertible design gives you three bikes in one, so you avoid repeated purchases. Built with high-quality materials and Irish assembly, it delivers real long-term value both in performance and savings.
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.
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.
This cool machine makes a lot of sense: great convertible geometry, excellent part spec and amazing build quality offers tremendous value
