Choosing the right mountain bike frame size is crucial. Every bike can be a little different in size. This mountain bike size chart will help give you a quick reference based on your height. This will not be the ultimate decision and we definitely recommend riding the mountain bike before you purchase it. For the money you will be spending on these bikes, make sure you get it right the first time.

Final Word

Don’t get stuck with a medium frame when you really need a large frame. Banging your knees on the handlebars will get old fast.

Make the time and always take the mountain bike for a ride before you purchase it. For more information, check out our post on How Are Mountain Bike Frames Measured.
