This has been around for a few years now. They are based in San Francisco, CA. That's one reason they mention lane splitting as one of the advantages of the C1.

It's a good urban commuter concept. Look around you in traffic on any day and probably 90% or better of drivers are solo, often in huge SUVs in the US. It's pretty silly really. I drive a Smart now, but am also married and work from home, so it works great as a city car for the runs into town for shopping with both of us or just running errands by myself. At 40-50 mpg, it's comparable to using the bike, but I don't have to gear up and have far more cargo capacity. The Lit C1 has a reverse too, which for urban traffic/daily commute needs would be a nice thing. Great for people that have to dress for work and don't see a Stich onesy as a real option.
Then there is the electric aspect of it. ~200 mile range @ 65mph cruise is pretty good by today's standards, even for electric motorcycles. 4-6 hours to charge, so even with a long commute, you could potentially plug in a work on 110v and be fully charged when you leave. 800# curb weight, top speed of 100 mph. The price is the show stopper for the masses though, $20,000-$25,000. They hope to lower that to $12k if production numbers get high enough, but I think that's unrealistic unless they prove to be successful over 4-5 years or more.
