Mountain Bike Sizing, Fit & Geometry

Getting a properly fitting mountain bike is the most important thing to consider before you drop in on a shiny new ride. Just like that pair of sweet jeans in the evo outlet for 70% off, it’s not a good deal if it doesn’t fit. Unlike denim, you can’t really alter aluminum or carbon, so it’s that much more important to get the right size mountain bike from the get-go.

Wondering how to pick the right size mountain bike? Read along and we’ll walk you through the process. For riders coming from another cycling background, it’s important to note that mountain bike sizing is significantly different than road bikes, and other kinds of bikes. If you are interested in learning more about today's spectrum of mountain bikes, and what to consider when making a purchase, check out our video on how to choose a mountain bike!

I don't usually comment negatively, but went all the way through the video and you've told me nothing about how to measure to size a bike for someone. All the other information was great, but useless on where to start when shopping (Size instructions). :(
