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,
ja bym zdecydował się na większą ramę. W przypadku crossówki przełoży się to na większą stabilność, choć być może warto będzie zainwestować w krótszy mostek.
W tej cenie warto rozważyć rowery marki Unibike. Modele Zethos i Viper mają o wiele lepszy stosunek ceny do jakości, szczególnie jeśli chodzi o osprzęt. Trzeba jednak przyznać, że ustępują (przynajmniej według mnie) wyglądem. Z drugiej strony będą mniej kusić potencjalnego złodzieja, a to coraz poważniejszy problem.
Witam. Biorę pod uwagę zakup roweru crossowego Trek dual sport lub Giant Roam modele z tego roku. Mój wzrost to 176 cm ,dł.wew.nogi 80 cm ,waga 80kg,czyli jestem na granicy rozmiarów. Na stronie Treka z tabeli wychodzi rozmiar L ale nie jestem pewny. Znowu na naklejce na ramie roweru w rozmierze M jest podane 175-50 czyli te 50 to by wskazywało 19,5 cala i już sam nie wiem.W Giant jest podobnie .Nie mam możliwości przymiarki na żywo roweru-proszę o poradę i z góry dziękuję.
ps.chyba,że jest jakaś ciekawsza propozycja w budżecie max 4000
Definitywnie 52!
Przymierzam się do zakupu rowera Romet Aspre 2. Mam 169 cm wzrostu oraz przekrok 78 cm. Jaki rozmiar będzie odpowiedni? 52 – S, czy 54 – M?
Dzień dobry, M i L to bardzo luźne określenia, skrajnie różniące się od producentów. Niemniej u większości będzie to L :)
