An intelligent electric bicycle includes a pedal drive unit, a power assist unit, a tread detector for detecting treading action on the pedal drive unit, a throttle unit for controlling output power of the power assist unit, a speed sensor, and a controller coupled electrically to the power assist unit, the tread detector, the throttle unit and the speed sensor. The controller operates in one of a user-controlled power distribution mode, an automatic drive mode and a cruise control mode according to the detected states of the pedal drive unit and the throttle unit and the moving speed of the bicycle.

1. An electric bicycle comprising: a pedal drive unit manually operable for driving forward movement of the bicycle; a power assist unit electrically operable for driving the forward movement of the bicycle; a tread detector for detecting treading action on said pedal drive unit; a throttle unit for controlling output power of said power assist unit; a speed sensor for detecting moving speed of the bicycle; and a controller coupled electrically to said power assist unit, said tread detector, said throttle unit and said speed sensor; wherein simultaneous treading action on said pedal drive unit and actuation of said throttle unit enable said controller to operate in a user-controlled power distribution mode, in which said output power of said power assist unit is controlled via said throttle unit; wherein, when the moving speed of the bicycle has reached a predetermined speed setting, actuation of said throttle unit without treading action on said pedal drive unit enables said controller to operate in an automatic drive mode, in which said output power of said power assist unit is controlled via said throttle unit; and wherein, when said controller operates in the user-controlled power distribution mode, and said throttle unit has been actuated to a current speed setting for a preset time period, said controller switches operation to a cruise control mode, in which as long as treading action on said pedal drive unit continues, the current speed setting of said throttle unit is maintained without need for continued actuation of said throttle unit. 2. The electric bicycle of claim 1, wherein said controller switches operation from the cruise control mode back to the user-controlled power distribution mode when said throttle unit is actuated to a selected setting higher than the current speed setting. 3. An electric bicycle comprising: a pedal drive unit manually operable for driving forward movement of the bicycle; a power assist unit electrically operable for driving the forward movement of the bicycle; a tread detector for detecting treading action on said pedal drive unit; a throttle unit for controlling output power of said power assist unit; a speed sensor for detecting moving speed of the bicycle; and a controller coupled electrically to said power assist unit, said tread detector, said throttle unit and said speed sensor; wherein simultaneous treading action on said pedal drive unit and actuation of said throttle unit enable said controller to operate in a user-controlled power distribution mode, in which said output power of said power assist unit is controlled via said throttle unit; wherein, when the moving speed of the bicycle has reached a predetermined speed setting, actuation of said throttle unit without treading action on said pedal drive unit enables said controller to operate in an automatic drive mode, in which said output power of said power assist unit is controlled via said throttle unit; and wherein, when said controller operates in the automatic drive mode, and said throttle unit has been actuated to a current speed setting for a preset time period, said controller switches operation to a cruise control mode, in which as long as there is no treading action on said pedal drive unit, the current speed setting of said throttle unit is maintained without need for continued actuation of said throttle unit. 4. The electric bicycle of claim 3, wherein said controller switches operation from the cruise control mode back to the automatic drive mode when said throttle unit is actuated to a selected speed setting higher than the current speed setting.
