Our bikes come in a range of sizes. Sizing also varies depending on model. You can find a sizing guide on each model's respective page, next to the size selection boxes. The best fit is primarily dictated by your height and inseam.
If you find that you're between sizes, choose the smaller size for a more aggressive/responsive ride. Choose the larger size for a slightly more upright ride. To err on the side of caution we typically suggest choosing the smaller size - as it's always easier to adjust the fit of a bicycle that's slightly too small in comparison to a bike that's too large.
Test rides are the absolute best way to decide what size works for you. If you're in New York City, you can come visit us at our Brooklyn Showroom for a test ride. Otherwise, we have a large network of stocking dealers across the country who will be able to offer you a test ride as well.
