Isn’t that exactly how you build a trail up a mountainside? They are usually a series of switchbacks.

Most people on most bikes can only take so much grade before climbing becomes impossible. A maximum grade setting would be very helpful for that exact reason.

Yes, but then you are doing a bunch of work — buying a (second?) fridge, paying to rent or own space to put it, making sure the fridge continues to run, making sure you don’t accidentally drink your wine before you meant to. If I cared about this property I would certainly pay someone much more than the cost of storage in electricity terms to not have to do any of that or wait a number of years to get a rolling stock going.
