"You can use your phone to unlock and lock your bike, change gears and select how much the motor assists you."

I'm guessing that "changing gears" is something that people in Copenhagen do rarely, perhaps using a wrench, like when you first get the bike or hook up a trailer. I miss flat cities.

On the other hand, a voice control gear changing app might be fun. I picture a dude on an all-white bike (tires too) wearing a clear-vinyl trench coat, telling his bike to "gear UP!" "gear Down...". The future is now.
