"STACK" is the vertical distance measured from the center of the crankarm bolt to the top/center of the head tube.
"REACH" is the horizontal distance measured from the center of the crankarm bolt to the top/center of the head tube.
Balanced Stack and Reach Dimensions
Why is it important to have a balanced and incremental differences within the size range?
We believe a bicycle with good geometry will help you maintain more control and increase the power that you generate which can result in longer lasting battery charge giving you more time to ride with power assist.
Many bicycles come in different sizes, but if you look closely at the geometry charts, sometimes the differences between "small" and "medium" are barely recognizable. Conversely, sometimes those dimensions are so far apart that you're left wondering which size you should choose.
We have created balanced and incremental dimension changes throughout our size ranges because a properly designed bicycle is one that has been created to fit YOU and not the other way around. It is one of the steps that we take to ensure that every rider can go farther, longer, faster, and in more comfort.
