Claim 8:
9. An electric bicycle speed control method executed by a control unit including one or more processors, the method comprising:
receiving a rotation speed of a pedal and a wheel speed;
generating a wheel torque command value using a wheel speed command value obtained by multiplying the rotation speed of the pedal by a gear ratio and a measured wheel speed value;
measuring a driving current of a motor for driving a wheel and a driving current of a generator driven by the pedal;
generating a motor driving control current for driving the motor using the wheel torque command value and a measured motor driving current value; and
generating a generator torque control current for controlling a torque of the generator using a value obtained by applying an assist level to the wheel torque command value and a measured generator driving current value.
