Love all of your recommendations, may i comment some ?
I think i've heard fast charger might damage life span of batteries, so i would suggest as the pedals option, having the choice about it. I'm not an expert so i don't really know about this.
You talk about about security features, and how alarms aren't loud enough. Why not try a new approach : sensitivity alarms around the legs/feet. I'm pretty sure we could do some "tap tap" system alert without being too damaging for the shells/screws/etc. This would be a nice double alarm system making sure you can't miss the signal.
What about accessibility to tire or inner tube ? When puncture occurs, you need a decent set of tools to fix it... (e.g. ACM)
Just wanted to share a bit since you're the biggest GW fan
