ESP32-based display and data logger for the Schwinn IC4

Similar projects worth following
BikeCU is an open-source project that enhances the functionality of the Schwinn IC4 indoor cycling bike by providing additional data not available on its built-in display. This includes power (watt) data, integer-style RPM, maximum heart rate, and more. Additionally, BikeCU facilitates the seamless transfer of data to a time-series database, such as InfluxDB, with per-second granularity. Users can then choose to export the data in TCX format for archival purposes and upload it to popular data aggregators like Runalyze or Strava.

While BikeCU has been primarily designed for the Schwinn IC4, it should be versatile enough to work with any BLE-enabled bike.
