CORRECT FRAME SIZE
When selecting a new bicycle, the correct choice of frame size is a very important safety consideration. Most full sized bicycles come in a range of frame sizes. These sizes usually refer to the distance between the center of the bottom bracket and the top of the frame seat tube.
For safe and comfortable riding there should be clearance of no less than 1 - 2 inches between
the groin area of the intended rider and the top tube of the bicycle frame, while the rider straddles the bicycle with both feet flat on the ground.
The ideal clearance will vary between types of bicycles and rider preference. This makes straddling the frame when off the saddle easier and safer in situations such as sudden traffic stops. Women can use a men’s style bicycle to determine the correct size women’s model.
The following chart and diagram will help you make the correct choice. Rider leg length refers to approximate pant inseam.
