Mountain Bike Size Chart

Mountain biking is good exercise. It is also a great way to get your adrenaline pumping, as well as it will give you wonderful nature experiences.
It is important to choose a right-sized mountain bike. Let us help you determine your bike size...  

How to Determine Mountain Bike Size?

Frame Size: Most mountain bike manufacturers use "frame size" as a size reference. This is actually the lenght of the seat tube (see illustration above). Frame size is given in inches (most often) or cm. See mountain bike size chart below to determine your frame size.

Alpha Size: Some mountain bike manufacturers use alpha sizes (like S (small), M (medium) or L (large)) as a size reference. See mountain bike size chart below to determine your mountain bike alpha size from your height.
