I would factor in local restrictions and maybe insurance coverage into your final picks for an ebike.
Class I & II ebikes (20 mph limit, PAS, throttle, 750w motor limit) can be considered bikes depending on your local and state laws. You might have more flexibility riding the ebike on pedestrian/bike trails, city sidewalks, and have automatic insurance coverage depending on the insurance company (I'm covered under my USAA homeowners insurance @ $500 an incident for my Radrover).
Class III Speed Pedelec might have more restrictions in your local area or state (helmet laws, registration, no one under 16 yrs old can ride, not allowed on bike only trails or sidewalks, considered motor vehicle and must follow motor vehicle rules, may or may-not be covered under homeowner's insurance, etc...). You may/may-not be covered homeowner's/renter's insurance.
No one is going to know a Class I from a Class III even after you tell them. I just like the flexibility I have with my Class II (especially when I travel with my ebikes to other states).
