Worth it for 80?

I would learn the quick checks on buying a used bike to make sure it doesn’t need anything, (bottom bracket wiggle test, wheel wiggle/spin test, emergency stop, dropping the bike, headset wiggle) and if it passes all of that, then 80 bucks is an alright deal. It’ll be good because it won’t attract as much attention to thieves,

if the fb seller posted a photo of the drive side, maybe post it here.
