sorry - you've lost me - the thing you showed a pic of is not a safety bicycle - a safety bicycle is basically the things we all pedal around on - even, with minor refinements TDF folk - they and we don't pedal around on anything like the object you posted.
Quite simply what I showed you existed in 1820 and matches (as well as any other bike around at the time) what you can see in the painting.
P.S. The safety bike was not originally diamond frame and could have different sized wheels. Derailleur came in 1950.
