Bike sizing guide
Bike sizes are measured by the frame size, based on the length of the seat tube. This is the measurement from the centre of the bottom bracket to the top of the seat tube, where the seat post is inserted. The frame of a bike changes in proportion to the frame size.
Stand over height
Stand over height is the clearance between the top of the top tube and the bottom of your crotch. It is important that you have enough clearance to avoid contact with the bike when you’ve stopped. For road and hybrid bikes 1 to 2 inches of clearance is required, mountain bikes require 2 to 4 inches. This is taken into account when finding the right size bike from the charts below.
