When selecting the appropriate size for a BMC Roadmachine, riders should consider both their height and inseam length. For instance, a rider who is 193 cm tall with a 91 cm inseam might choose between a 58 or 61 frame size. The choice of frame size also affects the riding position; for example, a taller frame size may lead to a more aggressive riding posture. It's important to consider both comfort and efficiency in riding posture when deciding on the frame size.

If you're between sizes, it is generally recommended to choose the smaller size. This is because you can always add a longer stem or handlebar to a smaller frame, but you cannot make a larger frame smaller. However, if you are more comfortable on a larger bike, or if you plan to do a lot of climbing, you may want to consider choosing the larger size.
