Yeah size is hard to tell though, go ride them. Don't think you have to be able to put a foot on the ground when you're on the seat either. You just need nut clearance straddling the top tube, and to not feel too stretched out.
The Schwinn's you posted have one piece cranks (garbage), steel rims (awful braking), 27" tyres (old standard), welded rather than lugged frames, before tig welding frames worked well, cheap stamped dropouts, garbage gaspipe steel, just all round very low end bikes. The worst you can get. Shit shit bikes
Those 2 $100 bikes i reced are good shit bikes. Still hiten steel, not chromoly frames, but lugged, with nicer dropouts, probably still nicer steel, and still stem shifters and suicide brake levers, but just all round higher quality, with decent drivetrains, proper square taper cranks etc. Basically decent, for still being relatively low end bikes for casuals. Especially the sekai.
The next two are low end still, but proper sporting bikes that people would have bought to ride seriously. They have butted chromoly steel frames, which is lighter and generally rides much better, indexed gears, 700c wheels which fit good modern tyres and more durable parts all round.
really it just takes years of autism to pick old bikes well and if i start giving tells then other autists will get triggered and start coping about how stem shifters are good.
good luck anyway lol. When you get something come back and post it.
