Looks like very similar construction to mine, but with a single motor instead of two. Be prepared to not carry it anywhere.
I do ride mine when it's wet, but not really if it's full on raining. If you open it up, you've just got a battery, speed controller and a load of wires - so unless it's getting entirely submerged - a bit of water isn't going to break it. If I do get it wet, I don't like to leave it wet, so I'll pop the top off and dry it out / leave it to air indoors. Basically, treat it the same as you would a bike.
I've had mine to pieces a few times, so any water rating is long gone. Be prepared to have to do this with pneumatic tyres. If you get a flat, it's a big job to change them. Doing mine involved removing the rear wheel from the scooter. Which means disconnecting it internally, which meant opening the whole thing up. And because the wheel cable goes through a small hole, which is bigger than the connector - it meant disassembling the connector to be able to take it off.
This is all caused by the lead for the wheel being the same side that the tyre has to be removed from. Maybe yours won't have this ridiculous design fail.
I'd suggest getting a set of honeycomb solid tyres ready for when you get that eventual flat, to move over to. They're fantastic, but did take about a month to get delivered.
