You can't send those without transportation to a big box store, because they don't have transportation.
Not for profits fulfill the roll of refurbishing bikes and teaching people about bikes in Detroit and other cities. They must give away the department store bikes after they teach young people. But of course the Hub hasn't been open since Covid struck except for a garage sale this weekend. I assume a few still get paychecks and insurance, but don't need to work. Additionally, I don't understand the prices for the refurb and sell model. I am baffled that they charge $300 and up for a 3 speed, and everything else is more, often more than 50% I charge for a well worn refurbished bike. Then there is the Madison WI NFP that asks $1000 for a steel TREK MTB on ebay. Go figure, cause I can't.

I prefer this concept more and always find 5-6 bikes for them annually.
