What and how to measure up
The majority of our sizing guides take into consideration your height and inside leg as it gives you two points of reference to help choose the bike size from our guides.

All measurements are best taken in your bare feet and with the help of someone else.

Stand upright against a wall with your legs together and shoulders back. Place a pencil on the top of your head and mark the wall, measure to the mark and take a note of your height in feet and inches.

To measure your inside leg, stand barefoot and measure from the floor, up the inside of your leg.
