What to know first

The most accurate measurement to determine which size bike you need is your inside leg measurement. To get this measurement simply stand against a wall with your feet flat on the floor without shoes on and place a book between your legs as high as is comfortable. Next, measure the distance between the top of the book and the floor. If you don’t have this measurement to hand then we’ve matched leg measurements to their average height and you can use this value instead.
