The only thing the Enertia Classic and the Hurricane share is two wheels, electric drive, and a $8-10k pricetag.
The Hurricane is a lightweight offroad-only electric bike. It may not have pedals, but it's still an electric bike @ 80-100 lbs with nice bike components.
The Enertia is a small street electric motorcycle. Lightweight in this case means 320 lbs.
The Hurricane is pretty similar to the Electricross Drift, produced in 2007 by the company that would become Zero Motorcycles. The ED was ~150 lbs, 14 kW. Same sort of bike-sized components, but much more power. And $7k.
My thought is the Hurricane is pretty nice, but hugely overpriced.
