A brand of bicycle intended for off-road use on dirt or gravel trails. There is no limit to how much you can spend on them. Some of the best ones are amazingly beautiful works of high-performance technology that are also tougher than nails.

Most mountain bikes, though, are bought for fairly cheap, sometimes under $100, at department stores under brands such as Mongoose, Schwinn, or Magna. These "mountain bikes" are covered with fancy graphics, lots of gears, and suspension, but actually work very poorly:

1) The components are all bottom-of-the line, even if they have good names such as Shimano. They are heavy, poorly machined, and wear out or break quickly.

Also knows as a "Freeway Friend" (United States, Canada, Australia, South Africa) is a term used to describe a motorist directly in front/behind you who is on a similarly long journey on the same motorway/freeway, especially at night and when driving alone.

Though you have never and are never likely to meet the person driving, you form a bond with them and can take comfort in the fact that you're not the only one driving hundreds of miles.
