NOT A TOY!
As a 6'2", 250lb guy, I chose the Rover 2 for me and my wife for criss crossing our farm. Got the big baskets for hauling eggs, garden items, etc. Our property has very few flat spots and some tough climbs. The Rover 2 gets it done. This thing is rugged. And powerful.
A couple of months ago, I took my kids on a very long ride in a nice park nearby, and eventually their Razers ran out of juice. With a mile to go, I stacked the two Razers AND my two kids on with me and we easily motored back to the car. The battery meter dropped one tick from fully charged. This thing is a tank. Huge fan.
Recently, my throttle screen was broke by impact with another object, and I had a new one 3 days after reporting it. They are working hard for my satisfaction.
