The invention discloses a novel bicycle transmission mechanism, and belongs to the field of bicycles. The device comprises a pedal force arm, a balance arm, a chain wheel disc, a pedal force arm bearing seat, a pedal force arm angle control arm, a balance arm bearing seat, a connecting arm bearing seat and a left force arm, the chain wheel disc is fixedly installed on a middle shaft at the right side end of a bicycle frame, and the pedal force arm bearing seat is fixedly installed at the edge of the chain wheel disc; the pedal force arm is fixedly installed on the pedal force arm bearing seats, the balance arm is arranged at the upper end of the pedal force arm, the balance arm bearing seats are installed at the two ends of the balance arm respectively, and the pedal force arm angle control arms are fixedly connected to the two ends of the balance arm respectively. The other ends of the pedal force arm angle control arms are fixedly connected to connecting arm bearing seats fixedly installed on the right side of the bicycle frame, and the left force arm is fixedly installed at the left side end of the bicycle middle shaft. The problems that an existing bicycle is strenuous in riding and not high in speed are solved, and the riding efficiency of the bicycle can be improved by meeting the riding requirements of the legs of the human body.
