I agree with the developer about the possibility of More Power as an uphill machine.

I like being able to kick free of the bike if say the front rim fails.

At least your bike won't get stolen.
17th June, 2014 @ 1:47 a.m. (California Time)
Just what you need if the bike falls over at speed, stuck in the frame!

There could be an entire website dedicated to failed bicycle inventions.

Too funny. I thought that, for all the trouble and radical design, the rider's bobbing motion would be used to drive the rear wheel.
In this case, all he needs to achieve the same effect is a spring-loaded bar that attaches to the seat post (or bracket) which then arches around to the rider's back; the contact point being a padded & somewhat body-formed brace which can be disengaged and reengaged as the rider desires. The rider's will need to be able to set the tension according to their own preference or pain threshold. Staying with a seat will ensure that max force is transmitted through the legs as no rearward redirection of forces will be possible, as they would be with a simple sling.

They should call it The Ball Squeezer 4000!

would sell more as the DCJ-34B the "Decolletage Jiggler"
" It’s worth noting that Jim Hurd, the former curator of the Bicycle Museum of America, says that at the turn of the century there were two buildings in Washington DC that held every patent in the U.S. One building held patents covering every type of product you can think of. The other building was reserved specifically for bicycle patents. It’s a manifestation of how much energy had gone into refining the bicycle and it’s the reason why it’s such a challenge for modern designers to make any sea-change improvements."

there isn;t any need to add extra muscles to the quads
the heart/lung/oxygen can;t even fully support them in most people
this is why adding the arm muscles, for instance, doesn;t add anything
well - except for:

As in the article go recumbent, Way more comfy.
Ive been bent for 20 yrs and wont go back.

This is not actually the stupidest idea I have seen, that would the stupid idea (German?), where a rider is totally suspended and sort of kicks or flails at the ground while waiting for a passing car to oblige society by sideswiping the rider. This bad idea is gigantically unsafe and looks more suited to a premise for a porn movie than an actual way to get around town.

In the late 1980's, this "problem" was addressed by a very simple device. (doing this from long-ago memory, so may not be fully accurate) I believe it was called the Cinto Belt, imported from Italy. It was a belt that you put around your torso, and a cable connected to the top tube. I know it existed, but i can't find anything on the web about it.

Seems like an overly complex (and dangerous) solution to a simple problem.
To reduce energy loss on the downward pedal stroke, why not just tether one's self to the frame at the hips (and adjust saddle angle)?

The designer of this must be having regular beers with the fitz bike designer. While I must admit this isn't on the same level of impracticality or misguided engineering as the aforementioned design exercise, I can't imagine the "power gained" would be worth the extra weight, inconvenience, and biometric limitation of the harness and support--especially considering that having any kind of harnessing system around the torso/abdomen will all but guarantee decreased breathing efficiency. As for safety, I mirror earlier contributors in my concern for the ability to separate from bike during collisions. I suppose one can augment a roll cage with airbag into this design. What would be even more entertaining is if we turned this into a fixed gear.

But as a 'power booster' it perhaps fails the logic test? Sure, you may be able to push harder each thrust, but you have only limited reserves of power/endurance. The power currently does not go missing, it is used in thrusting the rider up in the air, ie, more potential energy for the next thrust. If you push 10% harder each thrust, you will simply run out of push sooner.
.... dang... what I am trying to say is a cyclist going up a hill moderates his energy expenditure very carefully by choice of gear and cadence, in order to ensure he gets to the top of that hill with some energy in reserve to keep going. Being able to push 10% harder is not a benefit.
Having said that, there may be something in this in regards to a more comfortable seating arrangement ... currently used bicycle seats are akin to torture devices.

You don't get something for nothing. How do they think the 'bob' was gained in the first place? What are the stating their efficiency gains from? A piece of s%$t from kmart and a disabled rider? Have clip in pedals so you can upstroke and a helical crank and problem solved. Instead of clipping in, have a magnetic system which sense imminent danger of crashing and clips out for you?
This is the stupidest thing I have ever seen! No actually, i'll take that back. It will add value to society by providing the most hilarious fails compilations on youtube!

This could only come from the mind of someone who's an "architect and engineer" but not a cyclist. He "has been awarded 15 US patents," according to his site. That's a useless factoid. How about telling us which patents he has so we can see if they're any good?
17th June, 2014 @ 9:08 p.m. (California Time)
Not his one, your going to crash and burn and probably explode, just like in the movies.
18th June, 2014 @ 1:05 p.m. (California Time)
"architect / engineer" "designing bicycles"
18th June, 2014 @ 1:30 p.m. (California Time)
yes a Mechanic would have called BS on this project .."it looked good on paper" said the engineer !
18th June, 2014 @ 2:44 p.m. (California Time)
Makes the people riding it look like they just escaped the mental ward. I just can't believe how ridiculous these folks look hanging from that contraption. Back to the drawing board on this feeble downgrade.
18th June, 2014 @ 4:22 p.m. (California Time)
i'm starting to get it. the people who build these things just want publicity. for what, i don;t know. but no one would ever really expect this thing to sell, or even work. especially AFTER THEY TRIED THE @#$ing THING!
19th June, 2014 @ 6:57 a.m. (California Time)
Almost as bad as the Fliz. At least this one has pedals, but if you're ever in a crash that sends you flying forward, goodbye neck vertebrae.
14th July, 2014 @ 10:25 a.m. (California Time)
I think they should call this The Skull Planter. Please disable the front brake, sheeesh.

A pity there was so many negative posts,
a variation of this could be combined with an idea I had years back,
I wanted to place the pedals behind the rear wheel, (swapping the sides would allow standard components to be used, as effectively would be pedaling backwards) the legs go either side of rear wheel, like a face down recumbent, allowing the rider to push against the handlebars to stop them moving away from pedals. I was trying to support the rider from below, which I failed to resolve.
the advantage of more streamlined position, easy visibility, and more weight transferring to pedals as gradient increased.
your hanging the rider over a standard set up, doesn't gain much, as standing on the pedals is already possible, a pad to stop vertical rise, ie something to push against, could well increase power available.

We already have "clipless pedals", which give the mechanical advantage you're looking for with tethers and straps. If riders want to press against something with their backs, there are already existing recumbent bikes.
16th December, 2014 @ 8:17 p.m. (California Time)
How about putting the pedals such that they both rise and fall together and an air pump in the seat post with an air motor in the rear wheel so that as your fanny rises and falls air helps push the bike along while you bob up and down? You could shake a martini while pedaling along.
