See the basics of the Mirage recumbents revolutionary concept of a recumbent with a shaft drive. The bike looks pretty much as a nice urban recumbent bike but it should have much lower seating position according to my opinion. Otherwise it would be quite impractical to use it every day in the city traffic. However, the inventors claim that the high sitting position is due to good visibility in the traffic and that there is no issue with riding the bike among the cars and other vehicles.
