We're Here to Help

Now that you’ve found the bike of your dreams, it’s time to find the right size. All you need to know is your height, and then you can use our helpful sizing charts below to see which frame size is best for you. You can always call, chat, email, or message us if you’re between sizes or if you have any questions. 

Please note that frame geometry varies by brand. If the size that you choose isn't the perfect fit, we'll help you find a bike that is.
