Umm... No thanks I'll stick to my tradition bike.

I think it is an attempt to improve the average intelligence of the human race.

More chance to loose balance..

i'd use this bike if it worked upside down.

I want one hooked to my jaw, the most powerful muscle in the human body, for a bit of speed assist. I'd also save on chewing gum.

No handlebars, erratic steering input caused by the rider's hands going up and down, AND negative caster angle?
They might want to licence the design to EXIT as a suicide machine...

Do you use your extra octopus arms for signalling?

I'd have thought the hand cranks wouldn't add a great deal. The maximum power a person can output is likely limited by their aerobic threshold. As in there is only so much oxygen a person can intake and burn for energy and the legs can probably use all of it faster than it can be produced. Pedaling flat out for any length of time will result in you running out of breath because your muscles are burning all of what you take in plus a little more (anaerobic energy production). Adding the arms to the mix will relieve some of the work from your legs but I don't think you'd have any more energy to give. It would be like connecting a second engine to the same fuel pump in a car. Only so much petrol can be pushed into the engine regardless how many engines you have. Though I suspect for short bursts you could gain a boost due to anaerobic energy production. This would probably only be of use to people who have not trained their legs for cycling. Or maybe there is an efficiency to be gained by sharing the load over more muscles?

Oh come on, what is the point and what is wrong with a regular bike? Studies may prove there is more power available in the lab - but studies didn't prove this is unsafe. The 'bars' are way too narrow to be stable. What will someones reaction time be when moving from the cranks to the bars in a panic situation? What are the chances someone will miss the bars when letting go of the cranks and will imbed their teeth into the bars/cranks? What will the best way to go down a hill and this should be written into the owners manual? Not being negative but I have "safety" tabs on my front forks because some bozo couldn't work out a simple quick release - how do you think this bike will fare?

US$5,350 and it doesnt get disc breaks or have shocks. Lastly at 15 kgs that's quite heavy. No thanks, stupid concept let the free market concept decide its fate!
