An electronic device can be mounted at least partly in a frame of a bicycle and used to monitor operations or properties of the bicycle or one or more components associated with the bicycle. The electronic device may integrate and communicate with a variety of components including sensors to facilitate customization of monitoring by the electronic device. The electronic device can have a relatively minimalist design. The electronic device, in some embodiments, may include a display that does not present alphanumeric characters to an operator, and the display may instead include multiple indicators that individually or in combination present information to the operator, such as the level of charge of one or more batteries or an operating mode of the electronic device or bicycle.
