I Want to Bike

What Do I Need?

Fitting Your Bike > Bike Height

If your bike has a diamond frame (the kind with a bar across the top), stand just in front of the seat with the bike between your legs. Measure the space between the top tube and your crotch (figure 1). For road or street riding, a one-inch to three-inch space is safest.

Mountain bikes, however, need more clearance between the bar and your crotch (think about it…). If your bike has no top bar (e.g. “women’s bikes”), ask your bicycle store's staff to determine the best bicycle height for you.
