it is listed as a "5-speed"

Yes and no. It has horizontal dropouts, and if you intend on just going SS (not fixed), you can just throw a single speed freewheel on and go as is.

It looks to be a very heavy and low end bike (one piece crank, steel wheels, etc.), so spending a lot of money on converting or upgrading wouldn't be worth it.

Since you asked:

All of the good bikes have been rescued from basements across the country. Now you'd be just buying someone's junk.

yea, i just want a bike i can lock up outside when i run errands and not worry about it, i think that crank is perfect for SS since it already only has one chainring which looks to be a good start to a nice ratio for flat road riding.

how much would YOU pay for this bad boy??

It looks like an old Schwinn Continental... $45 at most.

Considering that I'd have to put in a good amount of work, time, and some money restoring and tuning it because everything is dry rotted and rusted, I wouldn't buy it at all.

i refuse to believe this. i am convinced some great uncle i didnt even know i had is going to kick-off and leave me a basement full of classic italian high end road bikes. i'll be sure to post pics when it happens.

i cant tell if that was a serious comment or sarcasm?? lol, damned internet...

but honestly, i would just be pulling off all the shifting equipment, shortening the chain to use the best gear ratio and replacing the brake pads, and using it as an errand bike (ok - MAYBE new bar tape)

Most yes, all no. This one falls into the "most" for sure.

$25 max.

At a minimum you'd have to replace:
Tires
Tubes
Rim tape
chain
grip tape
brake cables
brake pads
durailer cables

And that's assuming that nothing mechanical needs to be replaced. Then add the cost of the SS rear wheel + ACS freewheel.

It's fun restoring old bikes...if it's worth restoring.

I was very serious.

Also, riding an undated, rusty chain isn't a good idea.

From the sound of your posts you aren't really gathering opinions to use in a pragmatic decision. It seems that you want someone to say "GO FOR IT! It will be awesome!". Because you just want to do it because you want to do it. Which is fine. But, why did you ask us in the first place?

This does look like a Continental, and as such is worth little to no effort. But that's exactly the route the OP just indicated he's going to take, leaving it essentially as-is and removing the shifters + derailers. No new wheel / freewheel. I don't see how it's possible to know that all these other items need to be replaced from a grainy photo. Why would a SS need a derailer cable? It's not even a decent bike, but if the OP really just needs a beater for cruising around, this laundry list is an exaggeration.

i am honestly soliciting opinions, and i really do appreciate your input. my first goal of the inquiry was to find out if anyone knew anything about the frame itself (since i dont). that information will help me decide the value of the frame (the seller is asking 65) - which will help me make a reasonable and fair offer on the frame.

i consider myself an old timer, and i appreciate the help the internet offers in the matter of finding information fast, to think we didnt have "google" 15 years ago is mind blowing.

anyway, i am reasonable well aware of the mechanics of making the conversion, was just looking for facts and opinions on the value of the frame. again no sarcasm intended from me, thanks for your input.

riding an undated rusty chain with a singlespeed setup and 2 brakes won't kill anyone, it just may eat through the cog and chainwheel a little faster than normal.

Exaggeration my butt. I'd bet a $1 that everything on that list (with exception of the derailer cable since he's not restoring it) gets replaced before it's all said and done. And add Brake Pads to the list.

Everything on that list rots or rusts over time. That bike looks at least 25 years old.

i would also like to say that i think a lot of us build up bikes to be "errand runners", and by the time we're done, we would think twice about locking up in front of a store.

in my case, there are a few bars within 5 miles of my house, if i'm looking for something to ride out at night, and not care if i leave overnight chained up, or whatnot, i'm looking for the bare minimum.

if my chain breaks on the way home from the bar or the quiki-mart, i can chain it up and walk home.

well, the seller refuses to drop the price to my idea of a reasonable range, so i will be passing on this frame after all...

Schwinn Varsity. It's a tank. Yes, you can convert it but you don't really want to. Clean it up, ride it as is; great beater bike.
