Woom Kids' Bikes Size Information
Here's how to measure your child's inseam as accurately as possible:
- Have your child stand up straight against a wall wearing the shoes and pants likely to be worn while riding a bike.
- Take a hardcover book and place the spine of the book (facing upward) at your child’s crotch using the same slight pressure that would be applied by a bike saddle while riding.
- Mark the edge of the book's spine on the wall in pencil.
- Measure the distance from the floor to the marking as vertically as possible using a measuring stick or tape measure — this is your child’s inseam measurement in inches.
- Compare the measurement with the minimum inseam lengths in the table below.

Description
Ultra-Light Balance Bike for Confident First Riders
The woom GO 1 is built for toddlers aged 18 months and up who are discovering the joy of riding. At just 3 kilograms, this 12-inch balance bike is light enough for tiny riders to handle with ease, yet substantial enough to build real confidence. Child-specific geometry with an ultra-low entry makes mounting and dismounting simple, while the long wheelbase and forgiving steering geometry deliver stability that lets kids focus on balancing and having fun rather than staying upright.
Every component is purpose-designed for emerging riders: an ergonomic, banana-shaped saddle with a textured underside for easy carrying, narrow grips that fit small hands, a child-friendly mini V-brake with a bright green lever for intuitive stopping, and a flexible steering limiter that prevents overturns while building confident control. Lightweight Schwalbe tires grip reliably on pavement, grass, and gravel. The open seat tube design allows maximum saddle height adjustability, so this bike grows with your child from 18 months into the preschool years.

Finding the Right Size
The most accurate way to size a Woom is by your child's inseam — not their age. Here's how to measure:
Have your child stand straight against a wall in their riding shoes. Place a hardcover book between their legs, spine up, with gentle pressure like a bike saddle. Mark the top of the spine on the wall, then measure from the floor to the mark. That's the inseam in inches.
