I washed my 2020 Zero SR today and I noticed there's a little round hole about one inch in diameter in the front of the bike. It's in the flat plastic part kind of behind the front forks (sorry, I'm not a very technical person). I put my finger in (no pun intended) and it is full of some kind of grease that looks like Vaseline. I think I saw it before but there was a rubber plug over it. I guess it fell out. I hope I didn't get any water in.

My questions are, what is it for? How do I cover it up? Should I cover it up? Is it safe for me to ride with it uncovered? I tried to look it up on the Zero wiki but the site isn't working.

That is the port for the BMS (Battery Management System). The grease is dielectric grease. I'd recommend taping over it with electrical tape.

Yes, I'd definitly cover that properly, you don't want water going in there. Clean the surface around the hole and put some good quality duct tape over it.

Thank you very much for answering! I will tape over it today. Maybe I can find a replacement plug somewhere. I don't know how long I've been riding around with it open, and I do ride in the rain, but everything still works as far as I can tell.
