A gear step estimation method is of estimating a gear step of a switching transmission device (30) of an electric assist bicycle (10) including a motor (M) and the switching transmission device (30) which is provided in a power transmission path between the motor (M) and a rear wheel (78) and is capable of switching the gear step among n gear steps. The gear step estimation method includes a step of acquiring, at a first time, a detected gear ratio Rd that is a gear ratio of a transmission section that is the entire or partial power transmission path including the switching transmission device (30), a step of comparing the acquired detected gear ratio Rd with n preset gear ratios Ri set within a range of possible gear ratios taken by the n gear steps, and a step of estimating the gear step of the switching transmission device (30) as an m-step in a case where the detected gear ratio Rd matches an m-th preset gear ratios Ri.
