Note:

You should know that road bikes and mountain bikes are completely different kinds of bikes, and their measurements will also differ. Bikes produced in the USA are measured in inches, while some European brands like Haibike and Lapierre use centimeters. Sometimes the measurements of road bikes and mountain bikes are going to differ and that is when you can use their simple conversions. At IceBike we have included measurements in cm’s to help you out even more!

To measure your leg inseam, start by removing your shoes and standing upright with your feet positioned about 6-9 inches (15-22 cm) apart. Then, use a measuring tape to measure the distance from the floor to your crotch, as shown in the image above.

Can We Use The Same Measurements For Women’s Bikes?

When you compare specific women’s bikes to other unisex bikes their frame sizes might differ but that’s it. All of them have the same size whatsoever! The reason behind different frame sizes is that women have short upper bodies as compared to men. In specific women’s bikes, you will notice that they have short top tubes, this limits the reach and as a result, women don’t have to stretch out that much.

You have nothing to worry about though as it doesn’t affect the saddle height of the bike. Our calculator is recommended and well-adjusted for any kind of bike.

What To Do If You Are Stuck In-Between?

In some scenarios, the bike size calculator will suggest two different sizes. This means that both the sizes are best for you but that seems confusing, doesn’t it? Here’s what you should do when you are stuck in-between sizes:

The first thing that you need to notice is how long is the reach of the bike, it is affected the length of your arms and trunk length. The length between your hips and shoulders is known as trunk length. The longer the length the better!

If you have a short length then the best scenario for you would be to go for the shorter trunk length.

Does Size Matter For Different Types Of Bikes?

Different type of bikes is going to have different sizes, some times the bike type and brand is going to matter. As we have discussed before, road bikes are measured in centimeters while mountain bikes are measured in inches. This doesn’t matter much because our calculator gives the necessary quotation for each and every type of bike in their dedicated measurements.

There are some bike manufacturers that also design their bikes in sizes like Small, Medium, Large, and Extra Large. For more information, you can contact our bike specialists anytime!

Here are some of the bike size charts that you can use!
