Abstract
Based on upper limb torque by different angles of a back, distance between crank axis and chest and angles of hand-grips, this research is to develop variable hand bikes. By doing so, it is to offer guidance for its design. For this research three normal persons took part in the experiment. Results are as follows. First, upper limb torque was found to be the highest at 50 degree of a back and muscle endurance was shown to be the highest at 80 degree of a back. It means that as a back of a chair gets lower the speed and efficiency becomes better, which contradicts the subjective fact that K-type hand bikes would show the highest speed. Second, among types of grips of hand bikes 45 degree ones have been shown to be the ones with the highest torque. This is due to proper distribution of power of joints in arms, elbows, and shoulders. Third, in case of distance of 45cm between crank axis and chest, it has shown the most efficient torque. This is because of the effect of gravity and exhaustion when handling.
