City bikes are especially popular in locations where bikes make an appropriate mode of transportation in larger cities, such as New York. These bikes are not made for rough roads or for speed, but rather for convenience.

In order to buy an appropriate city bike based on size, it is important to note that you will need to measure your inseam, or leg length, in order to buy the right option.
