That thing is a legit superbike used in the MotoE race series and starts at $27k.
This is an e-bicycle:

They're essentially e-mopeds with useless pedals attached to the side. Top speed of 20-35 mph depending on model. Something like the Honda EV Cub, like
@Meriasek mentioned, is better in every way except that it doesn't let you pretend that you're a cyclist, which is a dealbreaker for the urbanist crowd.
Actual electric motorcycles have no problem carrying 50 pounds of cargo. Electric bicycles have zero safety features that modern motorcycles have (such as ABS and turn signals/brake lights) and their riders never wear appropriate gear. Cycling/Urbanists activists don't even believe in bike helmets, let alone full face helmets, impact gear, abrasion resistant clothing, or airbags. At 30 mph, you want to be wearing safety gear, and contrary to urbanist beliefs, most bike accidents are single vehicle and are not caused by cars.
