Seattle-area scooter rider here. I don’t ride rentals, I have a Boosted Rev and a Xiaomi M365 (what many rentals use). I don’t think the rentals and the Xiaomi are really meant to be used in the wet of a Seattle winter. Even the Rev, which touts its weather-resistance, needs a fender extender if you don’t want to get covered in crap (which makes me question how much they tested said weather-resistance).

That said, it’s just another single-track vehicle like a bike, and all that comes with it. Such as, riding on ice or snow is foolish. But even if it’s just rain, reduced traction means increased chance of locking a wheel and dumping it. Hence the likely reason the rentals went away, along with who the hell is going to ride them in the rain? (Answer: people that went ahead and just bought their own.)

In summary, my only complaint is that by just standing there instead of pedaling, it is kind of hard to stay warm when it is chilly. Otherwise, empty trails make for a great ride this time of year.
