Here is a pair of Gray Huffy Sigma's.

The larger bike is 20".  The only problem is that I can't get the neck out of the frame.  The bike rides great.  The seat post will be replaced with the shorter one (as this longer one is simply a pipe I bent).  With this sale, also comes the original tires.

The smaller bike is 14".  The only problem is near the seat post as the weld has separated from the rear brake area.  It is held together with zip ties.  My 60 pound child rode it recently and the whole bike works great.  With this sale, also comes the original tires.

These bikes are sold as-is since they are over 35 years old.  These are vintage bikes, expect rust, worn stickers, broken reflectors, and the wheel discs might have a crack.  The chain guard is also held with tape.    
No, I will not separate the bikes.
No, I will not accept returns.
No other pictures will be supplied.
Pick-up preferred.  

Sending these two bikes will cost under $200 depending on your location and the size of the box(es).  If you want shipping insurance, I can add it in at your cost.  I will do a good job packaging the bike and box.  However, I can't control the shipper's handling.  Packing will take a good hour, so please take that into consideration for cost.  If shipping is less, I have no problem refunding some money (this rate will be determined by me when considering time/packaging/insurance).  Please allow 2 weeks to package it, and another week for arrival. 

Questions, feel free to ask.
