Getting a Co-op Cyles bike from REI for your child but unsure about their ideal size?
The tables below are the latest (year 2023) sizing chart vs height from Co-op Cyles.
How to determine the ideal Co-op Cycles bike size.
The standover height is the most accurate predictor of the ideal bike size. Here’s how to do it.
- Measure your child’s inseam. It’s the distance from their crotch to the ground with their regular pants and shoes on.
- Subtract 3.8cm (1.5″) from the inseam measurement to get your Child’s Standover Height.
- Child’s Standover Height = Inseam – 3.8cm (1.5″)
- Compare your Child’s Standover Height against the tables below for the preferred bike mode.
- The ideal bike size should have a Bike Standover Height less than the Child’s Standover Height.
