A medium size mountain bike is a bicycle designed for riding off-road on rough terrain, with a frame size that falls in the middle range of small and large sizes. It usually has suspension on the front and/or rear, knobby tires, and wider handlebars for better control. The specific size of a medium mountain bike can vary depending on the manufacturer and model, but it is generally recommended for people with a height between 5’6” and 5’10”.

Mountain bikes are specifically designed for off-road terrain and are used for mountain biking, which is a popular outdoor activity for both recreational and competitive purposes. These bikes are equipped with thicker and wider tires, suspension systems, and stronger frames to handle the rough terrain. They are used for riding across trails, rough terrain, and rocky paths and are ideal for exploring mountains, forest areas, and steep terrains. Mountain bikes can be used for racing, commuting, leisure, and adventure biking.

To whip a mountain bike, the rider needs to take off from a jump and initiate a turn in the air. The key is to use body movement to rotate the bike while keeping it level. The rider should lean the bike in one direction while turning their upper body in the opposite direction. As the bike begins to rotate, the rider needs to spot the landing and aim the bike in that direction. The landing should be smooth, and the rider needs to maintain control to avoid crashing. Practice and patience are necessary to master the whip.
