A bicycle free from the conditions of having any part of the bicycle in the area between its wheels or horizontally adjacent to that area, except its pedal member and frontal portions of levers. A bicycle with two lever propulsion (14 and 15) machines having two levers formed in an approximate "L" shape. The shorter side of the "L" would be closely vertical and longer side would be closely horizontal when either lever is rotated to its lowest position. The pedaling system can also reciprocate with use of a high strength chain 6, having ends connected to the mid-portion of its levers. This chain 6 can be pulled over at least one mounted sprocket 56, mounted to the frame 4. Each lever is suspended above the ground by their connection to a member pivotal arm 53 suspended within the frame 4. The bicycle further has a reverse mechanism 30 to enable the bicycle to move backwards.
