BMX Bike

BMX

BMX bikes are popular among many people, especially the younger crowd who are interested in showing off their skills on their bike.

In order to determine the most appropriate BMX bike sizing for you, you will need to measure your own height accurately.

From your height, you will be able to determine the most appropriate sized BMX bike to opt for – including the crank size and top tube size.

To measure yourself, be sure you take your shoes off and ensure there are no objects on your head.

Stand straight up against a wall and mark the area on the wall where your head reachesat the top, and then take a tape measure to measure your height.

Below is a Size Chart that you can use for your reference once you have obtained your height.

City Bike

City

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.

Stand flat against a wall and then place your feet somewhat apart. Your legs should be apart as if you have a bike seat between your legs. You will then measure from the ground up your leg.

Below is a guide to help you determine the best-sized city bike to buy, based on your inseam length.

The following is a general guide to help you understand the best size option to buy.
