On our local MUP a few days ago I came upon two ebike riders that were drafting a group of road bikers. They were coming at me at a very good clip and there was a curve in the MUP, the two ebikes for some reason could not make this curve without swinging out into my side of the MUP. The road bikers stayed on their side. I almost decided to hold my ground but at the last second I moved off into the grass. I am glad I did as they had no clue on slowing down or taking any kind of evasive action to avoid a crash into me. They sped on by me wide eyed.
