Mountain bikes are bikes designed specifically for off-roading (mountains, trails, wilderness and gravel roads, etc.). It was born in San Francisco on the west coast of the United States in 1977. The various components of mountain bikes are different from ordinary bikes. They have cushioning properties, good impact-resistant tires, strong frames and high material stiffness, handles that are not easy to fatigue, and gearboxes that can run smoothly on steep slopes, etc., all of which make mountain bikes more suitable for mountaineering, off-road and outings.
When you choose a mountain bike, you must choose an appropriate size, and this appropriate size is determined by your height and habits, the most important thing is your height and inner leg length(inseam). In the table below you can see your height and recommended mountain bike bike with correct frame size.

Frame Size vs Wheel Size
For medium-sized adults, frame size is usually independent of wheel size. Without knowing the exact size, to determine the fit of the frame, the most common method is to look at the standing height, which roughly corresponds to the length of the seam in the human body, as shown in the figure above.
Although adult bikes (mountain bikes, road bikes and hybrid bikes) usually use frame size as the size standard, they usually directly state the wheel size instead of frame size on shopping websites. For example, the wheel size of mountain bikes is usually 24-29 inches.
