I'm trying to buy that damn e-bike, and I've pretty much given up on the hope that I'll find a bicycle retailer who'd accept bitcoin. Anyway, good luck to OP.
Well sad to see that you have not bought it yet but I do not think when the BTC price is around $6k, you will have this in mind to sell them now for the bike. OPs case is different since he needs money for living expense and I think this is where bitcoins are useful for all of us.
Image those people who has only bitcoins but no other fiats. They will have to sell some of their holding for living expense now since there are crisis everywhere.
