+1 to this. A steel frame 90s mountain bike with 26" wheels, some maintenance know how and about $100 in parts will get you thousands of km of riding with much less trouble compared to a fancy aluminium/carbon frame with hydraulic breaks and a drivetrain that locks the moment something goes slightly out of tolerance.
Only caveat is needing to buy some tools, but good tools will last.
Old school YouTube here. Short niche content, no clickbait or algorithm pushing. Nice birds, love it. I feel like you haven’t been able to browse and just watch simple original content like this since 2015.
My only complaint is it’s three pages down on videos.
+1 for frigate. I have some old V2 wyze cameras with openmiko for rtsp functionality.

Watch a few of these to get started, skip ahead as needed. It’s got some limitations but leagues ahead of freecad in terms of UI and workflow.
