I found it in the dumpster. I guess it's from one of those little toy motorcycles. It's about 8 3/4" in diameter and threaded for a freewheel on each side. The freewheel is huge and the teeth are for something like 1/4" pitch chain, maybe 6mm?
I guess I'll keep the freewheel and the chain tensioners and put the rest back in the dump unless anyone out there can use it. I thought you'd like to see it anyway.

That looks like the rear wheel of a pocket bike.

Try to see if the BCD on the freewheel matches a 4 bolt granny chainring, taking the freewhel off the wheel might require disassembling it.

You could make some rather interesting singlespeed freewheels with that. One possible use is as a low gear freewheel in a Retrodirect system.

On a side note, that looks like the wrist of a werewolf I see the moon is only half right now, so I guess the model is just naturally hairy. No offence...

Yeah, like maybe with one of those Schwinn Exercycle chainrings up front? I've got a Coppertone Continental coming in the mail....

Gimme a minute. I'll have a cocky response to that.
