Claims13
A bicycle electrical unit for a bicycle crank assembly, the bicycle electrical unit comprising:
- a housing configured to be mounted on an outer surface of a crank arm, the housing being a separate member from the crank arm. the housing being configured to be attached circumferentially between a first sprocket mounting arm and a second sprocket mounting arm of a sprocket mounting portion of the crank arm with respect to a rotational axis of the crank arm, the first sprocket mounting arm being a sprocket mounting arm that is disposed directly adjacent to a crank portion of the crank arm that has an opening for receiving a bicycle pedal;
- an indicator light that is provided with the housing;
- at least one strain sensor configured to be disposed on the outer surface of the crank arm, and configured to detect a pedaling force applied to the crank arm;
- a wireless communication unit enclosed in the housing and being electrically connected to the at least one strain sensor by at least one electrical wire to receive information transmitted by the at least one strain sensor;
- and
- a charge receiver port provided on the housing.
