Choosing the right sized bike depends on a few factors: the type of bike, your height and your riding style. It is important that you are able to safely mount and dismount the bicycle, and that while riding you are comfortable and can operate the brakes, steering and pedal without any added difficulty. A correctly fitted bike will be more comfortable, more efficient and more fun to ride allowing you to go further for longer. The type of bike that you buy will have a significant impact on the frame size that you need. Our size charts provide you with a general guide for each bike type to give you an idea of which size to choose.
The standover height measurement is taken when standing over the bicycle, in front of the seat, straddling the top tube of the bicycle. You should have a minimum of 1-3 inches of clearance between your inseam and the bicycle top tube. For ladies frames, pretend there is a top tube, because although you may be able to straddle the frame, you must also be able to reach the handlebars. Bicycles get longer as well as taller as you go up in size.
