Sometimes I enjoy riding my bike indoors. For years, I used Wahoo SYSTM (formerly known as the Sufferfest) and was quite happy with their platform. However, since I wasn’t using it frequently enough to justify the $15/month subscription, I decided to cancel. When I discovered the SYSTM app was essentially useless without a paid subscription, I started exploring alternatives.
A quick Google search for “python bluetooth devices” led me to Bleak (Bluetooth Low Energy platform Agnostic Klient), which sparked an idea: why not build my own open-source training app? And so Peloterm was born!
Here are the features that make Peloterm particularly appealing to me:
-
Multi-device connectivity: “Seamlessly” connects to my smart trainer, cadence monitor, and heart rate monitor
-
Clean metrics display: Shows the data I care about (power, speed, cadence, heart rate) in large, easy-to-read numbers
-
Progress tracking: Displays current time and a visual progress bar for each ride
-
Real-time graphing: Charts all four key metrics as you ride
-
Data export and sharing: Records rides to FIT files and uploads directly to Strava
-
Minimal screen footprint: Leaves plenty of room for entertainment (today I watched Giro d’Italia highlights while training)
-
Developer-friendly setup: Designed to be simple for Python users to install and run
Terminal window pip install pelotermpeloterm start
If you’re interested in trying Peloterm, I’d love to help you get started. Feel free to reach out or check out the project on GitHub.
Ride on!
