What size bike should a 5'2 person buy?

A person who is 5'2" typically fits a bike frame size of around 13 to 15 inches for a mountain bike and 49 to 52 cm for a road bike. It's essential to consider inseam length as well, as this can impact the fit. Many manufacturers provide sizing charts that can help determine the best fit based on height and inseam measurements. Additionally, visiting a local bike shop for a proper fitting is highly recommended to ensure comfort and safety.
