The invention relates to a bidirectional mechanical overrunning permanent magnet two-gear transmission and a gear shifting method thereof. A clutch comprises a transmission shell, a driving mechanism, a magnetic field modulation gear speed change mechanism, a speed change mechanism connecting piece, a gear shifting synchronizer and a clutch body. The single-stage coaxial magnetic field modulation gear serves as a speed change mechanism, friction energy loss of the transmission is reduced, and operation vibration and noise are reduced; a high-speed shaft of the speed change mechanism is selectively connected with a power output shaft through the clutch, the gear shifting synchronizer with the bidirectional mechanical overrunning function is connected with a low-speed shaft and an output shaft of the speed change mechanism, after the clutch is engaged, the gear shifting synchronizer automatically overruns, gear shifting without power interruption is achieved, and the gear shifting process is stable and free of impact. A coaxial arrangement method is adopted, the structure compactness is improved, the modularization degree of the gear shifting mechanism is high, and gear shifting operation is easy and convenient.
