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)
