This is a vintage 1970 Sears 10 speed Spyder 500 muscle bike. This bicycle has a unique top tube design where the seatstays run up all the way to the headtube in a twin tube design, split by the seattube. This was one of the answers sears had to the Raleigh chopper and Schwinn Krates/stingrays of the musclebike era (1963 - 1970's).
Paint is a yellow/green/blue fade from front to back. Great color, but lots of scratches and scuffs.
Headbadge is in good shape.
Chrome fork crown cover has a slight bend in it.
The spyder for sale has not been tuned up and is not rideable.
Both hubs will need a rebuild.
