What size bike do you need? (2023)

Are you looking for a new bicycle? Whether you're a professional cyclist or a beginner, the right bike size for your body makes all the difference in the world. Research shows that adults should do this on averageExercise for a maximum of 150 minutes per week, and cycling is a fantastic way to achieve this goal. But how do you know if you've found the perfect solution?

Basic terminology for bicycle sizing

First, it's important to understand the terminology used when it comes to bike sizes:

The two main measurements that determine bike size are the seat tube length and the top tube length. The seat tube is part of the frame into which the seat post is inserted. The top tube is a part of the frame that runs horizontally from the saddle to the handlebars.

Now that we've looked at some of the terms, it's time to get out the tape measure.


The first step in determining the bike size you need is:Measure your height: Your height will give you an idea of ​​what size bike frame to look for.

Stand barefoot against a wall and use a tape measure to measure your height from the floor to the top of your head. Record the measurement in both centimeters and inches.


Now it's time to measure your inseam. This is the distance from the floor to the bottom of your groin.

A common way to measure your inseam is to stand with your back against a wall and place a book between your legs. Measure from the bottom to the top of the book to determine your inseam.

Look at a size chart for bicycles

Once you have both sizes, you can use a bike size chart. Bicycle size charts usually use a combination of rider height and inseam to determine the correct frame size. Luckily we have a handy oneBicycle size chart onlinewith height information next to the frame size and general marking.

What kind of bike do I need?

Once you've figured out which frame size is best for you, the next question to ask yourself is what kind of riding you want to do. This will determine what type of bike you will ultimately need, which in turn will determine other important aspects of bike size, such as: B. the frame and wheel size.

We will discuss (and introduce) a few of them.tolle E-Bikes(also known as electric bikes), but the sizing guidelines are the same. E-bikes just have that certain wow factor that we just can't ignore.

Here's a quick overview of the different types of bikes (and the great e-bikes you need in your life):

Electric racing bikes

Whether you're riding the paved roads for leisurely excursions or for serious racing, road bikes like this oneVelotric Thunder 1 ST, have a lot to offer. The light, effective and aerodynamic design of this particular bike allows riders to ride faster on flat and uphill terrain.

Road bikes are ideal for competition, touring and physical fitness. Because of their speed and efficiency, they are also a common option for cyclists who want to cover long distances quickly and effectively.

Electric city bikes

City bikes, that sort of thingVelotric Discover 1 bikeare designed for daily commutes, leisurely rides and short trips around town. They usually have a relaxed geometry that props the rider up for maximum comfort. Your length is the most important factor in finding the right city bike.

In general, a bike should be able to stand above the top tube with a few inches of clearance. This ensures that you get on and off easily and can effortlessly reach the handlebars and pedals.

Off-road bikes

Off-road bikes are ideal for discovering new routes, tackling difficult terrain and enjoying the beauty of nature. In addition, they are great for cross-country and downhill mountain biking - two popular competitive sports. Because of their durability and adaptability, off-road bikes are a fantastic option for riders who want to explore the great outdoors and get off the beaten track.

When it comes to riding on difficult terrain like trails, mountains and forests, off-road bikes are like thatVelotric Nomad 1 fiets, are the point of contact. Like cyclocross and gravel bikes, off-road bikes have wide tires, suspension, and strong frames that can withstand the rigors of off-road riding. These are just some of the elements that make them strong and durable.

hybrid bicycles

Hybrid bicycles are designed for a combination of on-road and off-road riding. They typically have a more relaxed geometry than cyclocross or gravel bikes, with a higher bottom bracket and a longer head tube.

To determine the optimal size hybrid bike, check your height, inseam and riding style. The best bike gives you easy access to the handlebars and pedals without feeling cramped.

Then double check that the standover height is at least a few inches below your inseam.

BMX bikes

Because they are designed for tricks and stunts, BMX bikes are best suited for use on dirt, park and street courses. They offer a strong frame, durable components and a small footprint for optimal control and portability.

Riders of all ages who like to jump, spin and perform various stunts will love riding BMX bikes. They are also very popular in BMX racing, a high-intensity riding style and fast-paced activity that requires technical skill.

How do you find the right frame size?

Now that you're familiar with a few different types of bikes and have the measurements you need, you can start choosing a frame size and fit for your bike. Bike fit is how well the bike fits your body. This metric includes handlebars, saddle height, and seatpost.

Each type of bike has its ownspecific geometryand size method. No need to whip out your calculator: think of us as your bicycle geometry teachers.

Here are some factors to consider when choosing the right frame size and fit:


The handlebar plays a crucial role in determining the correct bicycle frame size:The steering wheel can affect your muscle activity.

If you prefer a more upright riding position, you may need a larger frame size. If you prefer a more aggressive riding position with lower handlebars and farther from the saddle, a smaller frame size may be more comfortable. If the comfort of your handlebar leaves a little to be desired,handlesare ordered.

Seat tube and top tube lengths

The seat tube length is the distance from the center of the bottom bracket to the top of the seat tube. This measurement determines how high the saddle can be raised, which affects the rider's leg extension and overall comfort on the bike.

If the seat tube is too short, the saddle cannot be raised high enough for the rider's leg length, causing discomfort and reduced power. If the seat tube is too long, the rider may not be able to reach the pedals comfortably, resulting in poor efficiency and possible knee pain.

The top tube length is the distance from the center of the seat tube to the center of the head tube where the handlebars attach. This size determines the length of the bicycle fairing or the distance between the saddle and the handlebars.

If the top tube is too short, the rider may feel cramped and uncomfortable with limited room to maneuver the bike. If the top tube is too long, the rider may feel overstretched and experience discomfort in the neck, shoulders or lower back.

inseam measurement

This measurement is taken from the floor to the top of your inside leg and can be used to determine the correct frame size for your body.

When it comes to frame size, bigger isn't always better. A smaller frame may be more comfortable and easier to maneuver for some riders. Women's bicycles, for example, often have a smaller frame to accommodate the typically smaller stature of women.

wheel size

Most adult bikes come with 26", 27.5" or 29" wheels. The size of the wheels affects the overall ride quality of the bike.

In general, larger wheels provide better traction and stability on rough terrain, while smaller wheels are more agile and responsive. In addition, you should know the wheel size of your bike when you buy itTyresofbicycle mudguard.

Bike sizes for women

Women's bike size may differ from men's bike size because women generally have a shorter torso and longer legs than men. Size guides for women's bicycles can help you choose the right size based on your height and inseam. In addition to the frame geometry, differences in the shape of the saddle and the width of the handlebars can also be taken into account when determining the size of women's bicycles.

Measure carefully: Research has shown that the likelihood of taking a risk increaseswounds in the saddleRaise when the bike's handlebars are lower than the seat height.

Sizing of children's bicycles

When determining the size of a children's bicycle, take into account the wheel and frame size and the age of the child. Smaller wheels can be more stable and manageable for younger riders, while larger wheels can provide more speed and efficiency for older kids.

The frame size must also be appropriatethe height of the childand stride length, and it is important to ensure that the child can easily reach the handlebars and pedals.

Note: Very young children (around 18 months or two years old) may be best suited for a balance bike. With these bicycles, a child can rest comfortably on the bicycle seat while walking and balancing. A children's bike size chart is your best friend when it comes to this type of bike.
