That's no doubt true, but I think the biggest problem was (and maybe is) price. They were something like $5K when they came out. I don't have hard data, but I'd be surprised if the median adult bike sold is more than $500 or $600. And the retail price of electric scooters seems to be $500.

In terms of sharing, too, I don't think it's a coincidence that the real ascension of bike and scooter shares is happening with smartphone penetration.
