A bicycle frame set includes a front fork, a head tube, a main tube, a seat tube, and a seat stay. The front fork includes a right fork leg and a left fork leg. The front fork is rotatably coupled to the head tube. The main tube is connected to the head tube. The seat tube is connected to the main tube, the seat tube being configured to connect to a seat post. The seat stay includes a first portion connected to the seat tube at a front end of the first portion of the seat stay. When a rear wheel and a front wheel are mounted to the bicycle frame set, the first portion of the seat stay extends in a horizontal direction substantially parallel with respect to a ground plane supporting the rear wheel and the front wheel.

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.
