The other change I'd probably want would be a wider all-weather tire for the snow/ice conditions that you see in many North American cities.
@emacsen I commute with a bicycle in the summer time, here in Oslo, Norway.
(But I don't use the bicycle during wintertime, because they salt the bike paths of Oslo and the salt eat the gears and brakes and all moving parts of the bike)
While recumbant bikes look comfortable, they seem much scarier. You don't have the vision you do on a regular bike, you're low to the ground, so vehicles don't see you, etc.
I agree with you on the gears thing. I forgot to mention that too. No gears is easy when the landscape is mostly flat.
Heck, someone could even make an e-bike with that configuration, if it's for commuting anyway!
