The drop bars are kind of a head-scratcher, especially given that it appears to be a single speed. They look to be newer than the rest of the bike, do make of that what you will.
I would have expected a coaster brake, but maybe the frame isn’t strong enough there.
Looks like the kind of bike you’d buy a bunch of for a lake/ beach resort that you can just leave around outside. (Solid tires, too)
Scott and YETI produced some plastic-framed MTBs in the 90’s, when CF was still too brittle for trail use. (They tried a lot of strange things in the 90’s)
