The invention discloses a central drive transmission sensing automatic speed change electric drive hub which comprises a wheel, a motor and a transmission shaft arranged on the wheel in a penetratingmode, the motor transmits power to the transmission shaft through a transmission sensing mechanism, a gear shifting mechanism and a power output component are arranged on the transmission shaft, andthe power output component sleeves the transmission shaft and rotates synchronously with the wheel. The gear shifting mechanism comprises a gear shifting synchronizer and a speed reducing assembly, thetransmission shaft is sleeved with the gear shifting synchronizer, and the gear shifting synchronizer can be combined with the power output component or the speed reducing assembly under the action ofa gear shifting fork. By the adoption of the technical scheme, the automatic gear shifting function can be achieved according to the real-time power condition, the electric two-wheeled vehicle can bematched with the actual driving working condition and the motor working condition in a self-adaptive mode according to the resistance condition, the electric two-wheeled vehicle has high climbing andheavy load capacity, the motor can be located on an efficient platform all the time. And the efficiency of the motor under climbing and heavy load conditions is greatly improved, and the energy consumption of the motor is reduced.
