In this article we want you to go step by step with us to measure the exact size of your perfect bike. We are planning to find you the perfect e-bike by measuring the bike frame size and its compatibility with your height. There are different kinds of ebikes, so, different kinds of size measurements are needed to find your perfect fit. If you are reading this for your kid, we will be talking about right bike sizes for kids too. We are determined not to leave any space for confusion about bike sizes in your mind.  

How to Measure Your E-Bike Frame Size?

If you are planning to buy an e-bike online, you will see e-bike frame sizes. It is important to know this size to have the most compatible e-bike for you. On the other hand, you may already have a bike and be wondering about the frame size of it. To achieve it you should follow some steps. Make sure you have a level surface and a tape measure. 

First, measure the distance from the center of the bottom bracket (this is the point where the pedal arms meet) to the top of the seat tube, you will get frame size in centimeters at the end of this process. We should warn you that size measurements for some bikes might differ, so it is always better to take a quick look at the manufacturer's sizing guide to be sure. 

The process does not end with just measuring your e-bike frame size. You should also have information about inseam length and flexibility. In the end, it might be more about personal preferences. If you are anxious about buying a bike of the wrong size, do not be. Many bike professionals offer services that adjust it just as you want. 

What is the Best E-Bike Size for Your Height?

As we stated above, there are many kinds of bikes on the market. So, you want to buy an e-bike that fits your size perfectly, but the problem is, which one? The good news is that many of the manufacturers show special interest in this subject to provide the best comfort for the customers. That is why there are often size tables in online shopping sites or e-bike stores. 

As we will show you in a minute, someone standing 5'6" to 5'9" might fit a 54 to 57 cm frame. These tables give you an idea about the correlation between your height and the size of the bike frame. We suggest you to give a quick try to the bike even if your sizes fit with the size of the bike because the conditions of comfort may change from person to person. Lastly, make sure there's about an inch of clearance between you and the top tube when standing over the bike, this will make things easier for you when you get off the bike. 

How to Measure Your Inseam for E-Bike Sizing?

One other thing that you will see while looking at bike size charts is your inseam size. In this step, you will need a book. Put a book between your legs, spine up, and take a position as if it is a bike seat, then measure from the floor to the top of the book; you will successfully have the inseam size of yours at the end. The right kind of inseam sizing is important for the comfort of your bike because it will affect your leg extension when pedaling.

How to Choose the Right E-Bike Size for Kids?

Safety is the number one priority for parents who want to buy a bike for their kids. The bike size plays an important role here, both for safety and keeping the love of cycling of your kids alive. The size of bikes for kids differs from the adults. Rather than frame size, wheel diameter is the one you will look at first. Typically, 12-inch is ideal for toddlers and when they are older this wheel size may be up to 20-inch or 24-inch. As we suggest for adults, we also suggest kids try the bike first. Make sure that they can touch the ground with their feet to be more stable. You decrease the risk of falling into an important amount just by following this step. 

What Happens If Your E-Bike Size is Wrong?

There are always professionals who will help you to find the e-bike that fits perfectly with your size or adjust it for you. On the other hand, you should not keep riding an ebike even if it gives you complete discomfort because of the size inconsistency. Besides discomfort, it is dangerous too because it affects your control. If the bike is too large for you, it will be hard to reach pedals. Also, if it is too small, it will restrict your mobility and cause dangerous situations. 

How to Adjust Your Bike for a Perfect Fit?

Adjustments on different parts of the ebike like saddle height, handlebar position, and stem length might give you the comfort that you were looking for. With a slight bend in your knee at the bottom of your pedal stroke, you can adjust saddle height. Make sure handlebars are easy to access while riding. Stem length might not be necessary to adjust, but if it is, you may consider changing it to reach the perfect riding experience.

Do E-Bikes Require Different Sizing?

Ebikes are not different from traditional bikes. There are different components like speed or weight but the measurement of sizes for eBikes is the same as regular bikes. One thing you should consider is that you should be aware of the weight of the eBike and make sure that the height is compatible with the weight for riding control. As we said before, having a test drive might be the ultimate key whether it is a regular or an electric bike!
