That’s quite a velocipede indeed!

Gymnacyclidium – This sounds like something for which you could be administered a shot to clear it up.  I thought these monstrosities worth looking at for the danger factor if nothing else.  Let’s hope the young lady is wearing adequate undergarments as it seems certain she will be taking a spill or two in the very near future.  I do like the curly cue fender thingy on the front though.

A bit of history about the bicycle: Invented more-or-less as we know it around 1817 with various propulsion systems added from about 1839 through the 1860s when bikes became more like what we know today.  A major step forward occurred in 1888 when Dunlop developed the pneumatic tire, making cycling more comfortable and practical.
