Some cities allow electric scooters and bikes on trains and subways, but some are strict about preventing this. What is it like in your city?
It seems like this is the ultimate combo to get around any big city these days. You get the best of both worlds - convenient last-mile mobility and traffic-free movement across larger distances.
Here in DC bikes are allowed on the Metro and most busses have a rack. Love the Metro for getting into town to ride with my buddy.
