Hell Yeah! Friday smiles...

Explain this to me Luci. Is the tiny crank because it's a hill bike or am I missing some gearing genius somewhere...?

That shit is mind blowing! You could stop the world turning with one of those!

      gears operates a clutch mechanism that allows the bevel gears to remain 
      meshed while operating in “free-wheel” mode, and in “working” mode when 
      engaged to the drive shaft. One lever moved forward or back controls the two 
      lower hill-climbing gears. When placed in neutral position, operating the
        second lever engages the level road gear.*

Still a valid concept today, to be fair. Simple but effective, and a great machine for chasing those high passes on on rough terrain. I rather fancy one!
