LA is surprisingly dense for an American city. I’m too lazy to look up LA numbers, but in the US as whole most car trips are under 5 miles. This is perfect e-bike distances, and after accounting for finding parking, walking across a massive surface lot or riding elevators down a parking deck, the e-bike might be just the same amount of time.
