For longer touring and casual sport cycling I want to finally get my hands on a bike computer. Have used my phone so far, but I don’t like
- battery life
- water situation when it’s rainy
- arguably not too good for the camera stabilizer
My requirements are not too high I would say, but I would like
- connectivity to some peripherals (ANT+ I guess)
- ability to add GPX files and also extract them
- not buy myself into some cloud (or otherwise fenced) solution
What it boils down to: What would be the least restrictive brand out there?
I am aware of https://github.com/hishizuka/pizero_bikecomputer but currently I don’t see myself tinkering that much – since I do longer tours I need some kind of decent case, a way to take it off and be a little tough.
(Sorry if this is not he perfect place, I could not think of another community that would fit well)


Man, I would love to do some cycle touring…
I don’t have any experience with open bike computers but I did set up a very old Fairphone 2 running Fairphone Open and the OsmAnd app for this. In airplane mode and only GPS for location the battery life was incredible, even without making use of spares. And you can of course import & export gpx tracks freely in OsmAnd, which is basically the best app ever.
A totally viable solution.
i second an old phone with one of these: https://wiki.openstreetmap.org/wiki/OsmAnd#Bicycle_and_pedestrian_features
i personally use organic maps: https://f-droid.org/packages/app.organicmaps/
