Bike Size Guide

"Ordering bikes online is becoming more and more popular."

  
You don’t need to worry about trying a bike out for size at a shop so long as you know certain things about yourself, or the rider the bike is going to be for.

You can often find your correct bike size just by your height, but it’s beneficial to know your inside leg measurement as well. 

To measure the inside leg (inseam), with shoes on, have the rider stand against a wall, with feet slightly apart.  Place a hardbound book between legs and raise until the spine of the book firmly hits the rider’s crotch.

Level the book with the floor and measure from the ground up to the spine of the book to find your inside leg measurement. 

The bike wheel size is measured from the outer edge of the tyre to the opposite side outer edge of the tyre. 

The bike frame size is measured from the point where the seat post enters the frame to the centre of the chainwheel.
