The acceleration of installing the acceleration sensor of three axes in CFR P frame of the monocoque construction, and the bicycle movement was measured. When passing over a difference part the manhole etc , 120m/s2 was recorded in the top of the seat tube. 40m/s2 was recorded in the getting on posture in which weight was put on the saddle with the back stretched in the acceleration measurement to the waist, and 20m/s2 in the getting on posture in which it made to the stoop and weight was not put on the saddle so much. The same degree of the acceleration as the observed maximum level acceleration understands the drop test from 100mm in height when usually running and it has been understood to obtain it The method of synchronizing the shape of waves in the direction of Z of the dropping impact to synchronize it in an independent sensor was effective. As for CFRP frame, the possibility of reducing the vibration of about 40Hz was shown.
