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. Mam zamiar kupić rower górski MTB INDIANA Storm X10. Czy przy wzroście 179cm
i długości nogi około 80 cm rower 19 cali będzie na mnie pasował?
Witam przymierzam się do kupna rowera MTB kellys thorx 90 2017 rok, koło 27,5 , wzrost 173cm przekrok 80cm, czy rama 18 cali czyli 46, 5 cm będzie dobra, z góry dziękuję pozdrawiam.
Dzień dobry,
Przy takim wzroście warto przymierzyć się do roweru na kołach 26". Jeżeli jazda będzie sprawiała córce wyraźne problemy, wtedy nie ma rady – 24", trzeba się jednak liczyć z tym, że rower szybko stanie się za mały. Co do rozmiaru ramy, trudno mówić tu o konkretach, gdyż producenci w tym segmencie raczej nie trzymają się uniwersalnych standardów. Będzie to najpewniej najmniejszy rozmiar na tych kołach lub uniwersalny dziecięcy.
dzień dobry,
Chciałabym kupić rower 10 letniej córce – wzrost 140. rower miejski. Jaką wielkość ramy i kół najlepiej wybrać ? Co by Pan polecił?
Zdecydowanie 17, jednak muszę uprzedzić, że na rowerze MTB nie uzyska Pan sylwetki choćby zbliżonej do wyprostowanej. Rower MTB to z założenia sportowa maszyna, a pochylona sylwetka jest zwyczajnie bardziej efektywna. Może warto zastanowić się nad rowerem crossowym?
