1. A battery boost converter system for a bicycle, comprising:
a bicycle frame;
a motor mounted to the bicycle frame;
a battery mounted to the bicycle frame and configured to provide power to the motor;
a boost converter that includes a boost circuit having a boost controller and a field-effect transistor, wherein the field-effect transistor connects to a circuit branch between the motor and the battery, wherein the field-effect transistor also connects to a common source of the boost controller, and wherein the boost converter is configured to:
receive a first output signal from the battery and to provide a second output signal to the motor; and
determine, based on an operating condition, whether to boost a voltage of the first output signal such that the second output signal has an increased voltage.
