vintage bike is it worth it??

If it runs, buy it! The engine is worth 150 easy by itself. It's either a Bike Bug, Free Spirit, or a TAS Spitz, all built by Tanaka. I had one, 23 mph top speed, smooth, relatively quiet. Easy starting too.

Parts are available, or easy to make.

The bikes worth about 25 bucks.

In fact, if it was near me, I'd be driving over there now.

Yep... What Joe said!

Dude My older brother claims to have a motor such as that in the garage that My Dad had from when we were the Pukes of Newport alias dukes of Hazzard. I will ask him to drag it out of storage and try not to scratch the woody on the way. I will donate it if you get a suitable chopper or swift looking frame. this is truly the old guy with a **** car type motor. I had such a neighbor who drove his on a 10 speed he was 78 and kept having heart attacks from the smog.
I imagine its all down hill from there He He
