Abstract

The steering wheel of the bicycle running and the acceleration of the saddle were measured. The tire inflation pressure was used to experiment as 800kPa in the bicycle frame of the chromium-molybdenum steel and the aluminum base alloy. The tire inflation pressure was assumed to be 450kPa in the cyclo crossing car of CFR P frame. The acceleration has increased as the running speed increases. The acceleration decreases by about 30% when making it to E150 of 150° in angle of the elbow as getting on posture for E180 of 180° in angle of the elbow. The acceleration of E150 in CRF P frame has decreased to 1/3 compared with getting on posture E180 in chromium-molybdenum steel frame.
