Bikes of the wrong size can cause a variety of problems. A bad sized bike will make you uncomfortable, preventing you from cycling as much as you would like or taking longer trips. Additionally, it may cause neck pain, back pain, and knee pain. A big bike may also make you feel less confident on the road, which may put you at risk of an accident if you are not confident on it.

Therefore, finding the right size of bike is more important than you think it is. And for that all you need is to measure your height and inseam or inside legs. Based on that size you can select the saddle height and pedal position, as well as the wheel size to choose a bike that fits you perfectly.
