The electronics will be somewhat water resistant, but we don't recommend riding in the rain. A big reason for that is the wheels (from standard longboards) are slicks and are somewhat dangerous in wet weather.
It is very capable at uphill climbing and downhill braking. Our ability to stay standing on it is usually the limiting factor.
As for why you would choose this over others, it's the lightest, has way more power than most, and has a fantastic design and riding experience.
It's unfortunate nobody has made a waterproof electric skateboard yet, it's what makes me stop buying any of them. How would it perform with knobby all terrain tires?
Reread the statement you are commenting on. The reason that you don't want to ride this board in the rain is inherent to longboarding, not to electronics. It is entirely possible to design the mechanical enclosures of electronics to withstand rain, it is simply a design choice. If people shouldn't be longboarding in the rain, why design for it?
