Sizing and Geometry

As the LittleBig changes between it’s three modes, it goes from the equivalent size of a standard 12 inch balance bike, to that of a 16 inch pedal bike. Both the saddle height and the handlebar reach increase, allowing for your child’s additional growth. As well as these frame adjustments, the saddle, handlebars and stem are like those you would find on an adult’s bike, so can independently adjusted to further fine tune the bike’s fit.

Sizing

In order to use a balance bike safely, it’s important that the bike is the correct fit for your child. Your child’s inside leg length should be the same or slightly longer than the minimum saddle height, which for the LittleBig is 350mm. It is important that your child can sit on the saddle with their feet comfortably on the ground. This will ensure that they have a successful start on their new bike.

How to Measure

Measure your child’s inside leg with shoes on, from floor to top of inseam. The inseam length should be at least the same as the minimum saddle height (350mm), or preferably a little longer.
