Shaft Drive Recumbents

After riding recumbent bike in Portland Oregon for over 8 years in the rain and mud. I see a real need for a shaft drive on the bike. There are a number of European manufacturer that support this, one of them is a Finnish designer.  Below is a picture of his high racer recumbent. On the  web site he reviews some of the advantages and disadvantages http://www.recumbent-gallery.eu/finnish-recumbent-with-shaft-drive/

There is an new Manufacturer of the start producing shaft drive recumbent.  As you can see from the video this bike is more of a commuter bike and set up so that it is close to ground for easy seating. .  The bike and the above photo is more of a high racer because of laid back sitting position and the larger wheels

Another manufacturer is FlevoBike out of the Netherlands they have been producing the green machine for Number of years.  This bike is also lower the ground because the lower wheels and the seating position is adjustable 

The problem is system of these bikes are available to U.S.  Which is a real shame.  Because I think there is real value in these type of recumbent bikes.
