i'm not sure about a word i'm gonna use: "performance ratio" to mean the ratio of energy produced against the energy consumed.
you mean it's less efficient regarding the performance ratio? it could be so and yet allow for a bigger amount of total energy transmitted to the vehicule. Do you understand my point? you could have to eat more often to make up for it but ultimately you might go faster and longer?? I understood that by using your arms, you deprive your legs of some oxygen reducing the burning of sugars for each leg and consequently the energy and strength of those muscles. maybe you're right. :(

Actually, the more limbs used, the less efficient it gets. The most efficient system is using one leg. The cardio and circulatory system can keep up with that at max effort. Adding a 2nd leg is less than twice as efficient because the body can't fuel both to 100% capacity. Add arms to the equation, and there's even less efficiency gain. I think the net gain isn't even 180% for arms and legs. Also add to the fact that you will be using a lot more core muscles to stiffen/stabilize the torso to be able to apply power with the arms, and add to that the decreased efficiency of the entire system due to the added weight and frictional drag of the extra drive system for the arms, and you can see why arm and leg systems don't appear everywhere. In a very short sprint where the body is going anaerobic anyway, the body can momentarily produce more power, but then you still have to overcome the losses from the more complicated drive train. Over there in Europe they race on row bikes and bents, but no one ever wins when they go against leg only bents. That's why :)
