Electric bikes are a huge improvement over standard bikes, and no improvement at all over a car for a significant number of use cases. They’re also no more useful than a bike in places where roads are poorly maintained, rain and snow are frequent, or no bike lanes exist. They’re not useful for taking kids to school, or doing significant errands. They are amazing for a single person to get around cheaply without killing themselves on every hill, and probably a godsend in SV. Most of the world doesn’t have SV’s weather though, and a lot of people have kids.
Electric bikes and scooters are very cool, but they’re no more a solution to the car in most cases than a motorcycle or Segway. They do nothing for people with long commutes, or who live in spread-out suburbs. No one is trading in their minivan for a moped.
