To ride is to be carried in a car, on a bike, or on an animal. When you ride a horse for the first time, it's often surprising how far off the ground you are.
You can ride in the back of a taxi or on a Ferris wheel at the fair. You can also ride — and control — a pony or a bicycle. As a noun, ride means "a trip in a vehicle," or a roller coaster or other amusement park entertainment. In the U.S., ride has also been an informal name for a car since about 1930: "Check out my new ride!"
