1. A method for controlling electronic shifting of a bicycle, the method comprising:
identifying, by a processor, a torque at a crank arm of the bicycle;
comparing, by the processor, the identified torque or a parameter based on the identified torque to a predetermined band, the predetermined band having an upper limit and a lower limit;
determining, by the processor, a target cadence based on the comparison;
determining, by the processor, a cadence band based on the determined target cadence; and
controlling the electronic shifting of the bicycle based on the determined cadence band, the controlling of the electronic shifting of the bicycle comprising actuating a motor of a derailleur of the bicycle for the electronic shifting of the bicycle when a cadence of the bicycle is outside of the determined cadence band.
