Vintage schwinn side hack bicycle bike

Description

Vintage custom-made Schwinn side hack bicycle bike with 3 extra metal rims. Condition is "Used.”
Circa 1970’s Schwinn Side Hack custom made to compete against the BMX side hacks of the day. With 20” wheels/rims. I acquired this bicycle in 1982 and has been stored in a garage since 1987. I am the 3rd owner: purchased from a friend who bought it from the person who engineered it to compete with BMX racers in Southern California. Made by someone with stellar welding and metallurgy skills. Not purchased from a store. If someone recognizes frame type to be from a certain year please message me and I will add that information.
Needs complete restoration OR keep rustic look by changing out essential parts. Plus includes the three metal mag wheels in the picture. My project long ago was to add the mags yet never had time to complete. Clearly rims are rusty and tires are dry and rotted out. Mag rims need bearings & restoration as well. Clearly has noticeable rust yet all welds appear intact. I would suggest to double check all welds due to age.
Sold as-is, no returns. Message with any questions. Pick up only in Southern California. Serious buyers only, pick up ZIP code 90713. Payment expected within two days and will hold for up to 5 days.
