Most ebikes have decently water-resistant controller housings. I'd avoid a serious downpour if possible, but it probably wouldn't be the end of the world if you get caught in one, and light rain is no problem at all.
micromobility
Ebikes, scooters, longboards: Whatever floats your goat, this is all things micromobility!
Transportation using lightweight vehicles such as bicycles or scooters, especially electric ones that may be borrowed as part of a self-service rental program in which people rent vehicles for short-term use within a town or city. "micromobility is seen as a potential solution to moving people more efficiently around cities"
While I don't enjoy it, I've been caught in heavier rain a few times while on my Inmotion V11 EUC and it handled it like a champ.
I have the same bike and just ride it but I do throw a poncho over it when I park. I think just avoid torrential downpours and you'll be fine.
For what it's worth, the 20X4" 15 psi tires seem to grip very well in wet conditions: There's a pretty solid contact patch and I haven't slipped once so far.
I can't speak to your ride, but I have no hesitation riding my ebike in the rain. I've got a Shimano mid drive designed for EMTBs, if it can handle muddy MTB trails a little rain isn't going to hurt it
I have a radwagon from radpower and it's gotten me through many wild downpours with no issues. Other than me forgetting my rain jacket sometimes :(
Fuck it, just ride!
