Disclosed are a torque sensing device of an electric-bike central motor, and an electric-bike central motor having the device. The torque sensing device of an electric-bike central motor, comprising a central shaft going through a five-way tube of the bike, a shaft sleeve that is disposed around this central shaft and will be circumferentially deformed when subjected to a circumferential torsional force, and a chain wheel disposed around the shaft sleeve, the shaft sleeve being provided with a torque sensing assembly that can sense magnitude of the circumferential torsional force to which the shaft sleeve is subjected, the torque sensing assembly being connected to a motor controller of the bike via an outlet device. The outlet device is composed of a movable magnetic core, a movable coil fixed on the movable magnetic core, a static magnetic core. This torque sensing device of the present invention has more reliable performance, stable signal transmission, and reduced friction loss.
