How to calculate frame size of your bike (adults)
- Stand with both legs about 15 cm apart and measure the distance from the floor to the crotch height. Measure the height in cm and not in inches.
- Multiply the number from step 1 by 0.68. The outcome of this sum is the frame size that best fits your new bicycle.
For example, if the result of this sum is 51.6, it is best to choose a bicycle with a frame size between 51 and 52 cm. Do you have a bicycle with a suspension seatpost? Then subtract 4 cm from the frame size. This 4 cm is used by the suspension in the seat post. Of course, the frame size also depends on your personal preference, for example with your toes on the ground or rather a whole foot.
