Bike seat.

This is another name for the bike seat, where your butt goes while your legs spin away. Saddles get a bad rap for being uncomfortable, but finding the right one for you is key — what works for your friend might not work for your rear end.

First, consider the type of riding you’ll be doing. Then visit your LBS. Some have special pads that you sit on to measure your sit bone width to find the right size. Ask if you can ride before you buy to test out different styles and sizes.
