My wife and I have two RadRover fat tire electric bikes. We're currently in Baja, and they have been excellent for both (hard sand) beach riding and touring the villages and towns. We purchased the rear carriers, and mounted cheap plastic crates on each bike for our shopping excursions. A few caveats. The RadRover is not for short-legged people, (30.5" stand-over height) straddling the bike is difficult. The step-thru versions would be better, but, the wheels are smaller. Two, the wheel-base is too short, 45" wheelbase, taking a turn in the dirt/gravel at speed is not recommended. Think incorrect caster on a car/truck, tire 'patch' on surfaces is wrong. Three, the weight. At 61 years of age, lifting these 68 pound bikes onto a 1up-USA.com bike rack, is well, not much fun! I highly recommend the 1up bike racks, expensive, but the tire locking system is brilliant.
For the $1,499 price, delivered to your door, these bikes are an exceptional value. The steel/chrome components are rusting on our bikes due to salt beach air, and being in the Florida Panhandle during three months of rain last winter (bikes outside under cover, not getting wet). I would try to rent a few bikes, including this brand, before making a decision. PS, I could be wrong on the wheelbase issue, in other words, 45" is 'normal' but, to me, turning in the dirt at speed is difficult.
