What I heard was that Buell was bought out by a hedge fund and they were trying to come up with a way to cash in on the Buell brand. Perhaps by making custom bikes using the last of the Buell (Rotax?) engines as shown above. My understanding is that they have no affiliation with H-D. I think Eric Buell went to work at Fuell (or something like that) and was helping them design electric bicycles and motorbikes. I don't think that company is going anywhere right now and I am not even sure if Buell still works for them. 
This new "Buell" has nothing to do with Erik Buell. Harley owned the name and sold it to some folks in Michigan. Like most startups they were having cash flow problems but it looks like they got past that with this new bike.
Erik has moved on to electric bikes. Similar performance but 50% more range than the Livewire but priced around $10,000 instead of $30,000. Built in storage as well. Purely a commuter. If you give them $200 for a spot they will discount another $2000. At least that was the last thing I heard from them.
