This type of bike is seen occasionally around Eugene. Looks comfortable but I don't know that I could keep one upright. Bike riders use the paths through Alton Baker Park a lot, rain or shine, as you see here. I learned this type of bike is a 'Recumbent'.

Recumbent Bikes

"Born out of the marriage between a bicycle & a deckchair, recumbent bikes offer a laid back reclined riding position which are chosen for, mainly, ergonomic reasons. The rider’s back & buttocks are well supported giving rise to a very comfortable riding position. With a smaller frontal profile &, hence, lower wind resistance, most recumbent bikes offer an aerodynamic advantage over conventional bike types. Available in a wide range of configurations, recumbent bikes can be long to short wheelbase, with mixed sized wheels, rear wheel or front wheels drive & offer different steering methods too – overseat, underseat or no-hands. I think that it is fair to say that recumbent bikes have a very loyal & bordering on cult following." - http://www.bikesoup.com/guides
