How To Check If A Bike Is Your Size

Let’s assume that you are standing in front of a bike that you are interested in, and you know the size of the bike. The size needs to be just about right, but how will you ensure it is a perfect match for you? Well, the method is easy to take off your shoes, stand right next to the bike and see if the bike size by height is equal to the measurement from the ground to your waist. 

Then sit on the bike and see if your toes touch the ground. The feet must touch the ground but partially.

If your feet land flat after you sit, then it means that your seat is too low, and your knees will bend while riding the bike, causing several joint problems. Therefore your feet need to touch the ground partially. 

If they do, that is the perfect bicycle size for you, and you shall buy it. However, while checking all these things, keep comfort in your mind. If it is your size, but you do not feel comfortable, then there is no point in buying that cycle.

These bikes are most preferred by village people or people from underdeveloped places. The reason behind this is that the roads of those areas are pretty bumpy and can damage a regular bike. Therefore, a mountain bike suits those areas and people.

Sport bikes: They are known for the extra additions such as additional gears, slim tires, and a strong body frame because athletes in different sports events use these cycles. The companies specially design these bikes for athletes, and only some can ride them with special training.

Adult bikes: They are probably regular bikes, determined by their tires. Adult bikes are the ones everyone can ride, men, women, even kids. The only thing that matters in these bikes is the comfort level.
