The embodiment is different in that the second embodiment further includes a warning unit 61 electrically connected to the microcomputer 21'. The microcomputer 21' determines that there is an instruction input to exclude the assist mode logic 22' and does not assist. When the mode is switched, or the automatic shift logic 23' is excluded and the shift control of the shift driver 31' is not performed, the warning unit 61 is controlled to emit a sound or a bright light to notify the rider. The warning unit 61 can be an LED (light emitting diode) to emit light, or can be a speaker to emit sound.

The second embodiment further includes a hand row controller 63 electrically connected to the microcomputer 21' for the rider to directly input a shift command to the microcomputer 21'. The microcomputer 21' is based on the hand. The shift controller 31' is directly controlled to perform shifting by the command of the row controller 63. The command input determination logic 24' does not include an instruction by the rider to operate the hand row controller 63 when determining whether there is an instruction input. This kind of design is mainly due to the shifting action actively controlled by the rider. The rider must be prepared psychologically. The rider has already understood that the shifting action is about to come, so there is no need to eliminate the assist mode switch or change. The action of the file is necessary. On the other hand, the operation of the upper control panel 41' is still excluded by the microcomputer 21' from the assist mode switching or the shifting operation, but the shifting operation of the shifting operation by the rider is not excluded.

In the second embodiment, the first condition may be different from the time interval of the first embodiment as the judgment condition. For example, the first condition may be that the handle 95' of the assist bicycle 90' is held by the rider's hands, the crank speed is greater than a predetermined value, or the pedaling force is greater than a predetermined value. Wherein, the first condition is that when the handle 95' is held by the rider's hands, the handle is 95' is provided with a sensor in the position of holding the hands (this is a conventional technology, not shown in the figure), and is electrically connected to the microcomputer 21'; when both hands are holding the handle 95', The representative rider is not operating the upper control panel 41' and returns to the normal riding state, and thus can be used as the first condition. The first condition is that when the crank speed is greater than a predetermined value, a speed sensor is disposed on the crank or the crank shaft of the assist bicycle 90' (this is a conventional technology, which is not shown in the figure), and is electrically connected to The microcomputer 21', and the predetermined value is 5 revolutions/minute; when the rider steps over a certain speed, it means that he has been riding attentively, so it can be used as the first condition. The first condition is that when the pedaling force is greater than a predetermined value, a torque sensor is disposed on the crank or the pedal of the assist bicycle 90' (this is a conventional technique, which is not represented by a drawing), and the predetermined value is 3.4475. Newton. Metric (Nt.m); when the rider's pedaling force exceeds a certain value, it means that he is already riding attentively, so it can also be used as the first condition.
