Lucky for me that this one came from the mid-Atlantic. It was ridden, but taken care of. It is a nearly 30 year old bike so it does have it's share of issues.

The patent listed below and the name Redlof provided research fodder. I was curious about the origin of this design.


Sometimes searching for patents can be frustrating. I finally found it. It turns out that the patent number listed above is registered to Robert W. P. Chen. The address listed is in Taiwan. To spare you from having to look it up, here are the first three pages of the patent. What is interesting is that there are 3 prior art references for Montague and Chen (the same Chen, I presume) has 2 prior art references. I've seen the 1990 patent from Montague. This patent/invention/submition was clever enough to recognize the Montague patent, but change it in a substantial enough way that it was granted it's own patent.








If you are interested in this, search for the patent listed above. Patent law is an interesting game.
