They are typically made for people who are not very experienced and should not be used for hard hills or races. Mountain bikes are designed for people who want to go on longer rides. They can be ridden uphill or downhill, and have a lot of gears to make them easier to ride. City bikes are perfect for people who need to get around town quickly. They have low speeds and can be ridden on the same streets as cars.
