This is the Clever Optimist, or Optimist Clever, which I encountered in Paris France a few years back:
I am fond of green colored bikes, as well as those sporting cantilever brakes, fenders, and racks. Plus, I especially liked the name of this one.
After returning state side, I did some modest googling to try to find out more about it. No luck, though I did find a link to this bike shop out in Portland.
In the ‘worth reading’ section of their website is this essay, which starts thus:
El socialismo puede llegar solo en bicicleta.
It is relatively brief, though dense, and like the proprietors at Clever Cycles, I recommend reading.
