The invention provides a pedal information sensing device and a bicycle, and relates to arrangement of a pedal driving part. Problems that in the prior art, pedal information detection precision is poor, and equipment is complex are solved. According to the pedal information sensing device, a rotation signal generation part is a magnetic ring; a rotation signal detection part includes a Hall element A and a Hall element B; magnetic poles are distributed in the circumferential direction of the magnetic ring; the polarities of two adjacent magnetic poles on the magnetic ring are opposite; a periodically changing magnetic field is formed along the circumferential direction of the magnetic ring; the Hall element A and the Hall element B are arranged corresponding to magnetic poles on the magnetic ring; and output signals of the two Hall elements are connected with an exclusive-OR gate circuit, output signals of the two Hall elements are connected with input of a first D trigger, output signals of the exclusive-OR gate circuit and the first D trigger are connected with the input of an AND gate circuit, and output signals of the AND gate circuit reflect pedal information. The pedal information sensing device can realize accurate detection of pedal information, and is realized by adopting simple hardware.
