Bike Wheel Size Based On Height

Sometimes referred to as 650b the 27 5 inch wheel fits right in between the 26 and 29 inch offerings.

Bike wheel size based on height. Most adult road bikes use 700c wheels whereas 26 is typically a mountain bike wheel size although in recent years mountain bikes are using larger wheels as well. After all the best way to test a bike technology is to take it for a ride. If you need to convert your measurements to inches divide them by 2 54. If we base your height on the standard bike size chart you fall under the frame sizes of 16 17.

Bike frames are measured from the middle of their bottom bracket to the end of their seat tube. This is because the axle sits in the middle of your wheel. And right behind those big 29ers are wheels of yet another size. This is classified under medium.

As we will learn more later on in this post. 12 inch 14 inch 16 inch 18 inch 20 inch 24 inch and now even 26 inch. While 26 inch wheels are still considered the standard for mountain bikes 29 inch wheels are fast on their heels. Unlike adult bike sizing done by frame children s bike size is done based on wheel diameter.

To calculate your bike frame size take your inseam in centimeters and multiply it by 0 575 for mountain bikes 0 665 for road bikes and 0 645 for trekking bikes. Examples of the 26 inch bike include commencal supreme park 2015 kona stinky 26 and rocky mountain maiden. If we take the 26 wheel as the base height the axle height for a 27 5 wheel will be 0 75 higher. At 5 6 you re not quite in that very small frame category and it s completely reasonable for a frame suited to your height to use 700c.

A 26 inch bike must have 46 48 cm frame size thereby making it the right fit for individuals with 5 0 5 3 heights. If we then look at the 29 wheel its axle will be 1 5 higher. While using your height as a guide is one of the easier ways to get an idea of your frame size it won t give you a perfect fit. We then divide the difference in wheel height by half to get information on how much higher the axle sits.

You can have two bikes with the same frame size but differing stand over height. Your wheel axle height sets your bottom bracket height. The wheel size is based on the diameter of the tire see below and as each tire size gets larger so does the size of the bicycle frame. Consider the following pros and cons of each and decide which size to test drive first.

12 inch 16 inch 20 inch and 24 inch. So which wheel size is right for you. This therefore means measuring the height of the child and matching it to the correct wheel diameter to ensure a perfect and safe fit allowing you to rest easy. Sometimes very small adult road bike frames will use a smaller wheel size like 650b but it s more common even for small frames to use 700c wheels.

The most common sizes are.
