Ride the bike for another couple hundred miles and you'll find you are changing PA levels without thinking about it. That's been true for me, anyway. I go up and down as needed or desired now. I usually like to ride in Eco or One, but for instance yesterday put it up into S to get through a green light (like
@Dunbar said.)
Many of your suggestions would raise the price, and Tora is trying to keep this a good choice as an entry-level ebike. For instance, hard wiring the light would make the cost go up. (I would like changing the battery to be easier.)
Some of your suggestions are just personal preference. Example: I use the cruise control all the time, even in traffic. Since hitting the brakes turns it off, there's no particular danger. I also do use the lower gears, so an 11-28 would be a loss of function for me.
All that being said, I appreciate your insights and hope you'll continue to share new ideas as you ride the bike more. That's the best part of this forum to me -- real world experience from diverse people with different riding styles!
