Which size bike is good for me? This is a question we get asked all the time. To be able to gauge this, first, you need to know your height in Feet/Inches or Meters/Centimeters. Once you know this information you can find which bike size is recommended for you.
Bike size is written on the frame of the bike with one of the following indicators (Size in inches varies with brands). The size is measured from the middle of the crank to the top of the set post tube. (This sizing refers to Giant Bikes)
XS – Extra Small – 14 inches
S – Small – 16 inches
M – Medium – 18 inches
L – Large – 20 Inches
XL – Extra Large – 22 Inches
Please note a question we get asked often is what’s the price per size of a bike. The price of the bike is the price of the bike and it doesn’t change according to the size. Any size of bike should be the same price.
|Rider Height (in)||Rider Height (cm)||Frame Size (in)|
|4′ 10″ – 5′ 2″||148cm – 158cm||13″ – 14″ (XS)|
|5′ 3″ – 5′ 6″||159cm – 168cm||15″ – 16″ (S)|
|5′ 7″ – 5′ 10″||169cm – 178cm||17″ – 18″ (M)|
|5′ 11″ – 6′ 1″||179cm – 185cm||19″ – 20″ (L)|
Getting the right size bike is very important and will influence the way you ride and how much control you have on the bike. Getting the right frame size is not the only important factor. You can also adjust certain parts of the bike as not everyone has the same body shape, leg and arm length and reach etc. This is called fitting the bike and you should spend some time doing this. You might prefer to make adjustments over time and tweak your setup the more you ride.
Things that you need to pay attention to and ask your LBS to help you set up are as follows:-
Seat Post Height – This can be adjusted with a quick release. Make sure the seat post is long enough to extend to your preferred pedaling height, but not too long that it won’t drop down inside the frame when you need to lower it to go downhill. A seat post can be cut to make it shorter or it can be changed to a longer one if it is not long enough. Standards seat posts can be upgraded to Dropper (automatic) seat posts when buying the bike. If your bike model does not come with a dropper, this will cost extra money.
Seat Position – The position of your seat can be adjusted forward or backward to help your reach the bars. It can also be tilted to a position that is comfortable for you, depending on your preference or any back pain issues you might have.
Stem Lenght – This is also a changeable part of the bike that can be swapped out and changed to a long or short stem depending on the reach that is comfortable for you. Having the correct stem length (reach) has a big impact on your bike control and steering comfort.
Handle Bar – The handle can also be cut to become shorter, this is a good idea especially for women who have more narrow shoulders. You can also exchange for different shaped or angled bars depending on your riding style.
Cockpit Set Up – This means everything on the handlebar is movable. Your shifter lever, your brake lever, and dropper switch or suspension lockout switches. This can all be moved and positioned to suit your riding style and the reach of your thumb and fingers to make it as smooth and comfortable as possible.
Suspension Air Pressure – In the case of bikes with air suspension, you can and should adjust the air pressure and speed of the suspension rebound to suit your weight and riding style.
Please note that changing parts or upgrading from the out-of-the-box set up of the bike does cost money. Some bike shops will buy back the parts you are swapping out.
We hope this helps you choosing the right size bike and setting up your bike for the perfect ride!
