russljames, what a bevy of pictures from that shop.
The seated worker, best thing for your back is to be seated instead of squatting all of the time, looks to be really happy in that busy environment. There is a truing apparatus on the bench, plus various tools on a board and a plethora of bicycle related stuff; my conclusion is that it is probably a very good bike shop to take your bike for maintenance and/or repairs.
The clock, now that is something I've never seen, at least not one like that. Interestingly, it appears to be made up entirely of bicycle related parts, and the time you pressed the shutter, was just past 16:16.
The front brake cam system is fascinating, deceptively simple and presumably powerful going on the length of the leverage from the pivot points; must try a bike with that kind of set-up one day.
The detail on the gazelle rear brake lever and bell, shows some fair wear and tear, with such a short focal length, that background blur tells me you must have been very close.
The cantilever rear suspension on the dirt bike looks like it could possibly be part carbon fibre, or is that just an overlay sticker? Regardless your depiction with the two main arms disappearing like two railway tracks getting closer as they head to infinity, is what makes this one standout somewhat.
Interestingly, the cantilever suspension system as we know it today, came about through necessity. I was at a talk given by Phil Irving in the late 1960's, who among other things, designed the post WWII Vincent motorcycles, winning Formula 1 car engines, etc. the question was why did he put rear cantilever suspension on the Vincent? Phil's answer was quite illuminating. He required reasonable suspension travel for the rough roads in the world at that time, but the reality was that the only spring steel they could obtain was 9" in length. The cantilever design enabled a multiplier of possible wheel travel from a small spring system. It is also reasonably light in nature compared to a standard wishbone suspension system, which is presumably why it is all the rage in bicycles today.
Just over 30 Black Lightning Vincents were manufactured, here you can see the cantilever rear suspension, including possibly the most famous Bonneville salt flats motorcycle picture which would make any safety expert cringe.
The Vincent Black Lightning was the fastest and most desirable motorcycle in the world when it was released in 1948. A factory-delivered Black Lightning

The Raleigh Sportif image, is a picture of cables, levers and light, one word sums it up; superb!
