Description

Resistance adjustable exercise bicycle

Technical Field

The invention relates to the technical field of exercise bicycles, in particular to an exercise bicycle with adjustable resistance.

Background

The exercise bicycle is called a power bicycle in the field of sports science, and is divided into two types, namely a vertical type exercise bicycle and a back-to-back type exercise bicycle (also called a horizontal type exercise bicycle), and the strength (power) of the exercise bicycle can be adjusted to achieve the effect of exercise, so that the exercise bicycle is called as an exercise bicycle. Aerobic exercise equipment that is typical of simulated outdoor sports is also known as cardiopulmonary exercise equipment. The body can be exercised for a long time and with proper intensity to promote the cardiovascular exercise, accelerate the metabolism and enhance the functions of the heart and the lung, thereby improving the physique of the human body.

Along with the continuous improvement of living standard, the attention degree of people to the health is higher and higher, so the exercise bicycle also becomes the exercise apparatus for most household exercises, most of the resistance devices of the existing exercise bicycles are of a water resistance type or a magnetic resistance type, the water resistance type exercise bicycle needs to add water or drain water into a water tank for carrying out condition when the resistance is adjusted, the water adding amount and the water draining amount cannot be accurately controlled, and the exercise bicycle is generally arranged indoors, so that water drops are easy to splash onto the ground when the water is added or drained, the ground is wet and slippery, people are easy to fall and hurt, the magnetic resistance type exercise bicycle needs to replace a magnet assembly when the resistance is adjusted, the regular exercise personnel cannot always adopt a resistance value for exercising, the regular adjustment is needed to adapt to the body-building rhythm of the user, and the exercise is needed to be stopped for replacement when the magnet assembly is replaced when the resistance is adjusted, the adjustment process is relatively complicated, and the body-building time is wasted.
