They look like E-bikes built along the lines of MTB (wide tires, schock absorbing fork, hydraulic disk brakes, frame also looks similar maybe slightly longer, MTB drivetrain and gear ratios) but most often also with luggage rack, built-in lights and fenders so city-friendly. Dropper posts are common. Brake cables are protected by having them internal (source). Luggage rack supports significant loads. The frame is almost always aluminum, even if I have seen a few very expensive models that use a carbon frame (image credit):
These bikes are universal, good enough for any road in any weather and any time of the year (accept studded tires), from city (both shopping and commuting) to the moderate mountain trail. They are convenient to ride but heavy, part of this comes from the large battery that can assist over tens of kilometers (I have seen a model with two large batteries and over 100 km range).
The price varies but the clever price is about $4000 with some models going as low as $2700 and up to $12000 on the top side.
SUV is the abbreviation from the "Sports Utility Vehicle" and probably inspired by some riding off-road vehicles on regular roads. But while road traffic rules often prevent an ordinary Jeep driver from riding out of tarmac, SUV bicycles do get into paths where they off road capabilities are in place.
