Oh this makes me sad

Unless you really want to sell them, I would consider keeping them. Our work travel hasn't panned out like we had planned when we purchased ours, but we're flying to CA next month with ours, we've taken them to San Diego before, we've taken them lots of places we wouldn't have taken regular bikes (where they could travel safely folded), and we've just ridden them when we wanted comfy steel bikes (and sometimes racks for carrying stuff). I truly understand if you need/want to sell them - but don't discount that life could change again
