We usually measure a bike by eye. It only takes a few minutes in the store. We think everything is perfect, the bike size is perfect, so we can pay and take it home. The next day we get on the bike, only to discover after a few kilometers that something doesn't quite fit, that it's not quite what we imagined. Did our eyes fail us? Perhaps! Choosing the right bike size requires greater precision. That's why, before ordering a bike from us, every customer takes a test ride.
Bike size - frame sizes
In reality, bike size is the frame size. Similar to wheels, they are specified in inches: 15, 17, 19 inches, etc. We've covered wheel size selection in a separate guide . You'll also find sizes listed in centimeters or sizes S–XL. Road bike sizes (from 45 to over 60 cm) are listed in centimeters, MTB frame sizes (from 15 to 22 inches) are listed in inches, and trekking and city frames (from 15 to 23 inches) are listed in inches.
When buying a bike online, the bike size is usually listed in the description, making it much easier to obtain the necessary information. When choosing a brick-and-mortar store, you can always ask a salesperson for help or check the size yourself. This is usually located on the seat tube. You can use our calculator or refer to the tables below.
What size bike is best for me?
There are many conversion factors that help calculate frame size based on inseam length. In the previous version of this article, we included one of these, but unfortunately, it caused a lot of confusion and uncertainty, especially since the results didn't always match the tables below. Therefore, we suggest starting your sizing based on your height. If you know that your body proportions, especially your inseam length, differ significantly from average, we strongly recommend trying on a bike in person. It's better to spend a little more time before buying a bike and then enjoy a well-fitting frame.

It's important to remember that the above tables are generalizations, so it's always a good idea to try on a bike before purchasing. This is because frames vary in geometry, intended use, and measurement methods. Furthermore, most manufacturers use two-inch sizing, so you usually buy a bike in an approximate size. If you're unsure about your size and need to make a choice, it's always worth asking a salesperson for their opinion.
Dzień dobry, chcę kupić rower MTB, dostępny w wersjach z kołami 27.5 i 29", jednak tylko w dwóch rozmiarach ram: 19 i 21". Z racji na wzrost 171 cm i odległość od podłoża do krocza ok. 77 cm do rozważań wchodzi jedynie rama 19" . Tabela wg wzrostu wydaje się zupełnie zaniżać rozmiarówkę, stąd mam pytanie odnośnie współczynników we wzorze 26/27.5 (x0,57) i 29 (x0,6). Czy rzeczywiście tak jest, jak sugeruje wzór, że rama 19" będzie odpowiednia (lub tylko nieco za duża) przy większym kole 29", zaś przy 27,5" lepszy byłby mniejszy (niedostępny) rozmiar ramy? Przeznaczenie do jazdy rekreacyjnej po szutrowanych/piaszczystych drogach w zasadniczo równinnym terenie. Nie wiem czy będąc na granicy już zbyt dużej ramy 19" lepiej wziąć koło 27.5 czy 29. Z góry dziękuję za odpowiedź. Pozdrawiam
Raczej będzie to rozmiar 17.
Witam. Chce kupić rower trekkingowy. Mam 170 wzrostu,a długość nogi 81 cm. Upatrzony model roweru jest 17 i 19 calowy. Jaki rozmiar lepiej wybrać?
Dzień dobry, niestety, znaleźć odpowiedni rower nie będzie łatwo. W takich przypadkach zalecamy przymierzanie się do największych ram dostępnych w okolicznych sklepach. Bardzo możliwe, że będzie Pani musiała pójść na kompromis. :(
