The invention discloses multi-purpose electric roller shoes. Two roller shoes form a set, each set of the roller shoes comprises a main frame plate, a bracket cover board, a drive motor, sliding wheels and a skiing board, wherein the sliding wheels are mounted below the main frame plate, the skiing board and the sliding wheels are mounted on axles, and the sliding wheels extend out from the downward direction of the skiing board and contact with the ground; fastening belts are arranged on the bracket cover board. The roller shoes can be used both on the ground or the snow ground, so that the application range is expanded, in addition, the structure is simple, and the design is ingenious; the brushless DC motor is adopted, so that the multi-purpose electric roller shoes can slide under the condition that electricity is available or not, in addition, a power supply can be charged during advancing, so that the problems that the conventional roller shoes are short in endurance mileage and can not be charged when a fixed power supply is not available are effectively solved, and the service space of the roller shoes is expanded.
