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. The gears will usually grind and skip no matter how well you adjust them. Rims are often steel, which quickly rusts and bends out of round, is very heavy, and is never seen on decent wheels.
2) They are no fun to ride. Most of them weight at least 31-35 pounds, and the full-suspension models weigh around 45! Try riding up a hill on
one of these. Most people just ride them around
the streets, and the knobby tires soak up so much energy you can actually hear it. Full suspension will completely absorb any power you put out. It feels like riding through mud.
Mountain bikes are extremely popular, though, accounting for over 90% of all bikes on the average college campus. They are easier to ride than road bikes, but will prevent you from ever enjoying bike riding. If they are
used for off-road use, they simply become a toy like dirt bikes that you can't use for everyday
transportation. Overall, I think they are a backwards development in cycling technology.
