LittleBig bike Features

#colour_kingfisher blue, lightweight children's bike for toddlers
Three Bikes In One

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

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.

Fast Rolling 14 Inch Wheels

The LittleBigs 14 inch balance bike 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.

A Real Bike, Not A Toy

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. 

Kids specific short-reach alloy brake levers work with little hands. Front and rear brakes ensure your little one can stop their bike quickly and safely.
