While bar size is mainly up to personal preference, you’ll want them to sit somewhere around your waistline. Some people prefer it a little above that, while others prefer it a bit below; that’s for you to decide! One thing to always keep in mind is that “bar height” is just the height of your bars; not the overall height of the scooter. Since the bars will always be resting on top of your headset, deck, fork, and front wheel, you can usually add 8 - 10 inches to the bar height to get the approximate overall height of your scooter from the ground up.
