design and manufacture of the stand rollick: moving to stationary bicycle converter

The purpose of this research was to design and manufacture various sports equipment, including cardiovascular system strengthening devices, which holds great significance in the public health. special mechanical parts were used for the design and manufacture of the stand rollick device. this device consists of two general parts with different fragments: a. the front part and b. the rear part including two rollers, metal structure, front wheel stopper, movable arms and its movable forks, stopper belt, machine wings and fixed shaft were used. the base of the stand rollick has the ability to be adjusted for all types of mobile bicycles, due to the fact that the chassis of this device is sliding and can be easily enlarged and reduced. due to the lightness and simplicity of the designed stand rollick, it can be easily adjusted in any place and any mobile bicycle can be placed on it. according to the results of the study, it can be concluded that the designed and manufactured device can improve physical fitness, especially the cardiovascular system, at any time and in any place especially in the cold and rainy weather, where outdoor exercise training is difficult for all people in all age groups. this device can be a good alternative to moving bicycles in critical times such as an outbreak of a viral disease.
