Probably the bike "jumps" a little on the treadmill due to some asymmetry of the wheel. The oscillation period corresponds well to the rotation speed (1.3 rad/s): 2*%pi / 1.3 rad/s * 9 rotations = 43.5 s ..
In addition to the oscillations there is a strange increase of the average acceleration with time.
