Bikes come in a range of sizes. The best fit for you depends primarily on your height and inseam. That's true whatever your gender, as gender matters far less in finding the bike that's best for you than other factors.
Every rider deserves a bike that fits and feels great, no matter their body type, style of riding, or level of experience. That's why we make great bikes for everybody and every body.
If you find that you're in between sizes, choose the smaller size for a more aggressive position if you are more flexible or prefer lower handlebars. Choose the larger size for a more relaxed position with higher handlebars. Or, reach out to your retailer or our experts here at Trek HQ for a quick consult.
