I like the styling.
For some reason riding in a recumbent trike/tadpole with an overhead fairing on the road would scare me more than biking in traffic. That extra foot of width just seems like it would be more likely to get clipped in traffic. I'm sure it's just a just a personal paranoia, as this thing is certain to be noticed by a vehicle coming from the behind, but *shiver* it's not for me.
The width steals away a bit of your ability to move alongside stopped traffic to guarantee you never have to sit through a stoplight twice. That's one of the benefits keeping a slower top-speed e-bike almost as fast as a higher speed vehicle in some commuting scenarios.
The overhead protection certainly makes it more of a year-round commuter for some climates.
I like this quote from their FAQ:
Is it safe?
A BugE offers more visability, stability and protection than a bicycle, or motor scooter. But there are large, dangerous vehicles and inattentive drivers out there, they pose a threat to everyone.
