I think all the arm-chair doom and gloomers aren't recognizing basic facts and math - a couple years ago, a much less established EBR was valued by Hero at approximately $50 million. Since that time, EBR has made huge strides and by any reasonable estimation should have gained value - let's say they're worth $75 million now. If a $75 million company can be obtained for $20 million, people will be interested. And articles like that posted on the facebook page just emphasize the competence of the bikes and value of the company.
If I had the cash (at least $100 million to not only pay off the debts, but keep the lights on until the company is truly up and running) I would consider it a sound investment - as long as the bidding doesn't go too high. And I actually think that will be the story when the dust settles - there will be several interested parties and the bidding will go well over the $20 million required to cover the debt.
