Yesterday I got my hands on an old soviet city bike "Ukraine". It was produced in Kharkov velo factory, 1987. I could not help but notice that the bike frame has different geometry compared to my Peugeot city bike from around the same time frame. As you can see on the image there is a noticable difference in the frame geometry, adding up to about 10-15cm more to the length of the soviet bike. I have also noticed that other bikes from Soviet era also have wider frames, e.g. Diamant bikes that were produced in East Germany.
So, my question is, were bikes in the past indeed "longer" and why was this the case? How has city bikes geometry changed over the years? Do they still produce bikes with "old-style" geometry?
