R-Walker Selfsustaining Free Energy bike from Mexico

[lancaIV]

In the spanish/english translation from the Oaxaca Government is another fault :
http://www.miconversor.com/3000-pesos-mexicanos-a-dolares-americanos
not 3000 US Dollars !
But the right price estimation we can took from Raul Grajales Guzman answer at the first post.

Sincerely

Found another story in Spanish on this, and they also seem to
be implying that it is a self running bike:

Original Spanish:

Google English translation of the relevant part:

"R-Walker (Oaxaca, Oaxaca) Manufactured Cobao students (School of Bachelors of the State of Oaxaca), the R-Walker, is a prototype of
alternative and renewable energies rural and urban use.  Do not use fossil fuels or recharge batteries, it is one of the first worldwide to be self-sustaining?
It's kind of compact bike capable of transporting a person almost permanently, as it has a self-sustaining electric motor and therefore does not require any
fuel to operate.  R-Walker was created by Victor Ricardo Matias Garcia and Raul Grajales Guzman."

It seems unlikely that it would really be self sustaining and not have caused a major
sensation on all major news networks around the world. Something doesn't seem to add up. 
How could a reporter report on a story in which they state that a machine is self sustaining, and not
ask all kinds of questions about how it is supposed to work and how they confirmed that it is self sustaining. 
It's like reporting on a story where you say that so and so invented a machine that can transport
people anywhere in the world by dematerializing them and rematerializing them somewhere else, and not asking
any follow up questions. Duh! Someone here with a technical background who can speak Spanish should contact
the teacher at that school involved in the project and get clarification on how the bike is supposed to work according to
the teacher.

The set-up looks like a basic regenerative braking arrangement.  That's a good thing to have but not new.  Neither is using super caps to buffer the electrochemical battery.  If the thing goes down a 1km 3% grade, it is a safe bet that after coming back up that grade the battery will be more depleted than at the start.

Here's another news story on the R-Walker.
The students definitely appear to be saying that they think the bike is self sustaining.
It is just very vague about how this is supposed to work exactly. This story has a little bit more
detail, but not much:

Google English Translation:

Have just 17, but their names are entered in the registers: they are inventors.  This is Raul Grajales Guzman and Victor Ricardo Matias Garcia, students in sixth semester of the College of Bachelors of Oaxaca (Cobao) 01 Pueblo Nuevo, who using the principle "the matter is not created nor destroyed, only transformed", designed and They produced the R-Walker, an autonomous bicycle without pedals capable of generating its own energy of motion.

This prototype won the gold medal awarded by the jury of the International Robotics Tournament held in Barcelona, ​​Spain, in the category of innovative project

The invention was born a year ago from a set of ideas and trials Club Cobao Multimedia and Robotics, currently composed of 32 students.  The starting point was European prototypes of urban mobility.  The challenge was to create one that does not use batteries and is capable of driving on the streets of Oaxaca considering their difficulties.

"We also saw the problem that there are young people who walk hours to reach their schools, in Oaxaca people walking hours in the mountains to get to take your truck and then plan to make a prototype that could help these people, however we find the first problem: how are you going to give a person a system of mobility if you tell them they have to buy gas or have to recharge a battery in eight hours, "Ricardo explains.

From the above approach Raul and Ricardo, under the guidance of Professor Alejandro Villavicencio Arenaza, managed to develop a prototype using renewable energy to generate own speed.  "We have five months without discharging the battery, this means that the prototype works," says the student.

The R-Walker has a suspension unpressurized oil-and-only tires with asphalt type.  "We worked mainly on design dynamo used on bicycles for the lighthouse. It is used to feed the stored magnetic fields in the capacitor of the left side and from there the battery is recharged and the battery moves to the engine and the engine start the cycle. The loss is 0.3 volts between the generation and use, " explained broadly.

Notice that the students said they have gone five months without discharging the battery... 
It seems to be that some sort of dynamo (generator) charges the super caps which is supposed to keep the battery charged.
Normally that wouldn't be self sustaining, so how???

They could ride the thing downhill to charge it, and then push it back up hill to preserve the charge.
