Rarest "krate" bike would be the Grey ghost,single speed. Under 300 ghosts made,much less for single speed.
i would say that the most common one would be the Schwinn apple krate i have the lemon peeler and Columbia playbike
There are quite a number of blogs and sites dedicated to fixing equipment. The Schwinn 431 elipticals manual is actually posted on one of them: http://printer1.blogspot.com/2009/06/schwinn-431-elliptical-service-manual.html This would be a good place to start.
1977 would be my guess
The most standard place to start to buy Schwinn equipment would be the Schwinn website, which shows the entire range of elliptical styles and prices. However, when trying to find all price ranges and comparing options, looking at Sears, Amazon, or eBay can be helpful as well.
how much are the speed racer comics worth
The Schwinn Airdyne has many available outlets to buy. Some places where they can be purchased are Walmart, Sears, eBay, and Amazon. Other online shopping type websites would also see good results.
Anything I've seen on Schwinn has the k#'s ending K499***, would appreciate any help, thanks.
i would say about 2,ooo if in good condition.
Their average speed would be 40.3 miles per hour which meant that they were consistently impeding traffic by driving well under the minimum legal speed.
Not with our current mass, it would take too long to accelerate to that speed while also not killing us to make it worth doing.
The Schwinn 420 elliptical is available for online purchase at numerous places but I would suggest looking at Amazon first mostly because it give you options for new and used ones.
