Abstract: A bicycle stand is provided, including: a first connecting portion, a main body and at least two supporting members. The first connecting portion is configured to be assembled to a frame of a bicycle. The main body includes a rod member and a base connected with the rod member, and the rod member defines an axial direction and includes a second connecting portion detachably connected with the first connecting portion. The at least two supporting members are connected with the base and respectively include at least one supporting surface configured to be abutted against a placement surface, and the at least two supporting members are movable relative to the main body between an expanding position and a folded position.

Abstract: A control system of an electric bicycle includes is provided, including: a driving motor, a database and a control module. The driving motor includes a transmission module and at least one first sensor configured to sense at least one dynamic parameter of the transmission module. The database stores a plurality of riding mode information which respectively include a plurality of simulation parameters. The control module includes a setting unit, a computing unit and a control unit. The setting unit is configured to input at least one setting parameter, and the computing unit calculates a simulated moment of inertia and a calculation result data related to the simulated moment of inertia. The computing unit outputs at least one control signal according to the calculation result data, and the control unit receives the at least one control signal and controls a driving state of the driving motor accordingly.
