Measuring your inseam height: the key to finding the ideal bike size

To get an accurate measurement, follow these steps:

  1. Find a smooth wall and take off your shoes.
  2. Stand with your back straight and your heels resting against the wall.
  3. Place a book or a rigid board between your legs, horizontally, with the top touching the wall.
  4. Measure the distance from the floor to the top of the book or board.
  5. Write down the measurement in centimeters.

Tips for accurate measurement

  • Make sure your back is straight and your heels are firmly planted against the wall.
  • Keep the book or board horizontal during measurement.

How to use the size chart?

  1. Find your inseam height in the "Inseam Height (cm)" column.
  2. Find the type of bike you want to buy in the "Bike Type" column.
  3. The bike size at the intersection of both columns is the one that best fits your height.

Important

  • The size chart is a general guide, and the ideal size may vary slightly depending on the make and model of the bike.
  • We recommend that you try the bike before purchasing it to ensure that it feels comfortable and allows for correct posture.

Additional factors to consider when choosing a bike size

While your inseam height is the most important factor in determining the right bike size, there are other factors you should also consider to ensure the bike fits your needs and preferences perfectly.

Additional factors to consider

Length of your arms

The length of your arms influences the distance between the saddle and the handlebars. If you have long arms, you may need a bike with a longer top tube.

Type of cycling you practice

Different types of bicycles have different geometries. For example, mountain bikes have a shorter top tube than road bikes, allowing for a more upright and comfortable riding position.

Saddle and handlebar adjustments

Most bikes allow you to adjust the height and position of the saddle and handlebars. This allows you to customize the bike to suit your size and preferences. We recommend using the bike saddle adapters, as well as a bike handlebar adapter.

Personal preferences

Some people prefer a slightly larger size bike for a more relaxed riding position, while others prefer a smaller size for greater agility.

Tips for choosing the right bike size

  • Test the bike before you buy it: The best way to know if a bike fits you well is to try it on. Hop on the bike and ride for a few minutes to make sure it feels comfortable and allows for correct posture.
  • Consult with a cycling expert: If you're unsure of which size to choose, consult a cycling expert. They can help you choose the right size for you, taking into account your height, arm length, the type of cycling you do, and your personal preferences.
  • Consider buying a used bike: If you're looking for a used bike, it's important to make sure the size is right for you. You can use the size chart as a guide, but it's also important to test ride the bike before purchasing.
