Bicycle electric power unit
First Claim
1. A bicycle electric power unit comprising:
- a power source;
a power source controller configured to turn the power source on or off;
a power source voltage detector configured to detect a voltage of the power source; and
a first power source switch configured to selectively supply electric power to the power source controller, the power source controller being configured to turn the first power source switch off when the power source voltage detector detects a voltage of the power source being at a predetermined value or less.

Abstract
A bicycle electric power unit supplies electric power to a bicycle motor unit having a power source, a power source controller, a power source voltage detector, a first power source switch and a second power source switch. The power source controller turns off the first power source switch when the power source voltage detector detects a voltage of a specific value or less. The first power source switch supplies electric power to the power source controller when the power source is on and blocks the electric power to the power source controller when the power source is off. The first power source switch is turned off by the power source controller when the power source is on. The second power source switch is disposed between the power source and the motor unit. The second power source is turned on and off by the power source controller.

15. A bicycle electric power unit comprising:
-
a power source;
a power source controller configured to turn the power source on or off;
a first power source switch configured to selectively supply electric power to the power source controller;
an operating switch operatively connected to the first power source switch and the power source controller such that the first power source switch is turned on by operation of the operating switch; and
a second power source switch operatively coupled to the power source and operatively controlled to be selectively turned on by the power source controller when the electric power is supplied from the power source to the power source controller through the first power source switch. - View Dependent Claims (16, 17, 18, 19, 20)
