with that direct drive hydraulics you're running into major problems with the drive because of the forces put into it by the pedals. Ideally you would have the pedals driving a shaft and the shaft driving the hydraulic motor iliminating the issues you're going to run into with seal problems.
Actually, it might be more efficient than you think. How do you think an automatic transmission works in a car? The torque converter uses a hydraulic coupling, the engine is not directly coupled to the transmission.
@ct92404 I've done a simular experiment like this before and it diffinitively showed that air was a poor method to use, for the compression was not enough nor efficient enough to move my piston with a load of about 10 lbs of resistance. It was easier to move when it was just a chain.
Water had simular issues, but with water, using my method, it was not able to move the piston with out some kind of runoff, and refill.
And if bikes are going to run on water, it should just be steam.
Well, I was thinking of some kind of small impeller. When you pedal, it turns an impeller which sends hydraulic fluid pressure to a small turbine at the back wheel. Also, you probably wouldn't use water, you'd use some kind of oil or something with more density. I don't know, it's just an idea. I'd like to experiment with this myself sometime too...I just don't have any money for that right now :(
@ct92404 oil would be a good start, but then what type of oil would you use?
and would it be good to use on a large scale, meaning would there be enough for everyone's bike?
also I'm thinking more about my piston idea. basically have one small piston attached to the pedals and run a fluid line to another on the wheel. and if that works, then with some alterations it could also be attached to the front wheel for more torque. Like rock climbing; so now we can use both wheels.
cannon dale spent a few million on a series of prototypes of this concept. It was really well done. Very neat. ...and horribly inefficient and maintenance heavy. They cancelled the project due to inefficiencies inherent in the system.
from the looks of it, it will utilize a similar theory to that of a water wheel. the fluid will be moved by the pedals, with internal paddles and porting. the gear changing, would be simulated through valving. different porting on the valves would work similar to that of placing your thumb over the end of a garden hose. the more your cover the end, the higher the pressure, I would assume this is the principle behind this bike. Great Idea!!!!
All this is is a computer drawing, for all we know it could be nuclear powered or powered by the heat of a working colony of ants or termites that live inside the frame and are fed on a sucrose mixture once a week!

So what? instead of chain, it uses air or water compression to move? that's not very efficient.

2 brakes on the both frame forks are better and safe

It will have a good performance and value only when high pressure CV transmission is used. But leakage is inevitable.
