Claim 7:
8. A method for controlling a derailleur in low battery remaining capacity, the method comprising:
determining whether a remaining capacity of a battery of a shift lever is smaller than or equal to a first lever battery threshold;
when the remaining capacity of the battery is determined to be smaller than or equal to the first lever battery threshold, at least one of gear positions of the derailleur is invalided and non-selectable by the derailleur;
wherein after the at least one of the gear positions of the derailleur is invalided and non-selectable by the derailleur, the method further comprises:
determining whether the remaining capacity of the battery is smaller than or equal to a second lever battery threshold, wherein the second lever battery threshold is smaller than the first lever battery threshold;
when the remaining capacity of the battery is determined to be larger than the second lever battery threshold, the derailleur is allowed to be shifted to another one of the gear positions that is not invalided and non-selectable by the derailleur.
