Otherwise, there will be a high chance of not getting proper balance while riding, which may result in injury. Some common problems with riding a wrong size bike have been described below. Lack Of Control It will be difficult to maneuver and control balance while riding a wrong size bike. This can seriously affect your riding speed and comfort. You may also have to face different unpredictable things with the wrong size bike. For example, lack of control over your bike can lead to serious accidents and getting injuries. Back Pain Riding the wrong bike will leave you with poor posture, causing pain in your lower back. For example, if you have a bike with a large frame, you will need to lean forward to reach the handlebars. Besides, if you bike on aerodynamic bars, the position of riding can strain your neck and upper back, which leads to back pain. Sore Wrists And Ankles If you ride with the wrong bike for a longer time, your elbows will lock, and your wrists will be bent. Riding this type of bike will put a lot of stress on your ankles and wrists. Additionally, if your bike’s frame is too large or high, it will cause you to lean your body forward. As a result, much pressure will be put on your wrists, causing sprain in your ankles. What Factors Are Related To The Right Size Bike? What Factors Are Related To The Right Size Bike? While sizing a bike, you will have to consider several factors that help you get the right bike. Some significant factors related to the sizing of a bike have been explained below. Frame Size Riding with the wrong frame size can cause lower back pain. The frame is actually the top tube of a bike which helps determine whether your body is straight with the bike. It is the main part of a bike that enables slight modification in stem length, handlebars, and saddle setback. Besides, the frame helps to know how far or close the handlebars are from your sitting position, which affects your bike handling. For that, your riding comfort, speed, and safety will completely depend on the frame. So you should consider the size of the frame while choosing a bike. Wheel Size The size of your bike's wheels will determine how much rolling resistance you get on the road. If you have bigger wheels, you can easily overcome bigger obstacles. So, choosing the right wheel size is crucial to determining whether your bike will meet your needs and fit your riding style. For taller riders, bikes with wheels size 20″ or above will be ideal. On the other hand, shorter riders can ride bikes with 16″ or 18″ size wheels. Rider Height Standing over height is usually measured from the top of a bike's top tube to the ground. Normally, riders with longer legs require longer top tubes and vice versa. For optimal size, your crotch and the top tube should be separated by a few inches. If your height does not fit a bike's frame, you will encounter different injuries and be deprived of overall comfort and performance. In that case, riders should choose a bike according to their height and riding styles. Conclusion Riding the wrong size bike will not only carry you forward to different accidents but also harm your riding style. So, if you are a pro BMX rider, you should always ride the proper size bike. However, most riders find it difficult to determine the bike size. For that, you have explained what size bike will be best for BMX riders in this context. Typically, bike size completely depends on the riders' height. You will just need to measure your height and compare the measurement to the mentioned chart to get the right size bike.
