we just stumpled upon this project on twitter:
It’s essentially an eink gps device with high battery life, good contrast for reading under the sunlight, as well as ESP32 (which has an awesome community).
The displays are from https://www.good-display.com/
I think this is a great project and should be announced on Kickstarter or Indiegogo. There are several use cases beside cycling just as : GPS for fishing, sailing, hiking, etc.
Everywhere where you need a high battery life, you are outside (i.e. outside readability) as well as simplistic device with no distraction.
Curious what will come out of this project…
