When is the best time to buy a bike?

BMX Bike


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 reaches at 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 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.



Hybrid bikes come in many different options, but a general rule should be followed when it comes to determining the best size option to choose.

With a hybrid bike, you will usually measure your height, as well as your leg inseam length. You will then buy an appropriate bike based on the size of the frame.

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

Bike Size Chart For Mountain Bikers


Mountain bikes tend to provide more heavy-duty features as they are made to withstand tougher terrains.

Power is often considered the number one priority with these particular bikes. With a mountain bike, you will use a similar measuring system as with a city bike – you will need to measure your leg length, sometimes also referred to as your inseam, in order to determine the best-sized bike that you should buy for yourself.

See above for a basic mountain bike frame size chart to help you determine what size to opt for.

Bike Size Chart For Road Bikers


A road bike combines specs of various options into one bike that provides both power and speed.

These bikes are primarily made to be used longer roads and are made to be durable. To determine the best size bike to buy, you will use the same measuring system as with a mountain and city bike.

Your inseam needs to be measured in order to determine how large your bike frame should be for a comfortable ride.

You will find a reference guide to help you choose the best-sized road bike according to your inseam length below.

Bike Size Chart For Kids


When buying a bike for your kid, the measurement system will work very similar to how you would do the measurements when you decide to buy a BMX bike.

You would essentially measure the height of your kid and then from there, use an appropriate kids bike size chart in order to determine the most appropriate sized bike to buy.

IN addition to taking into account the height of the kid, however, with a kids bike, you will also have to take into account the age of your kid.
