I think it only has an electric motor. No ICE.


I think this vehicle is a electric internal combustion hybrid.

for example the statements..

"It’s based on the principle of converting energy through speed and distance travelled; the engine becomes self-sustaining,
generating more than 2,000 revolutions per minute.

A battery is used to spark ignition, and afterwards without using any combustion the vehicle can carry up to 110 kilograms
and travel at more than 60 kilometers per hour."

"The engine", "battery is used to spark ignition", "Without using any combustion"

argues people are seeing this wrong. I think this is a hybrid with two motors in parallel

There is a lot of evidence from the pictures. In one of the first pictures where he is kneeling besides the bike there
appears to be exhaust all over near his hand. Also there seems to be a spark plug under the heat shrink tubing in another.
In one of the videos he seems to be positioning his hand as if to feel a cool exhaust gas stream.

People are arguing that the bike is doing more then electricity alone is possibly capable of and I agree.

Either way it is a bad commentary on the people writing the article.

  The scooter is not a hydrid, and is not gas powered, as it has No gas motor.
  It utilizes a self regenarative charging system to keep the battery up. And, it is an all electric self sustaining design.
  It can run at a top speed of 25 kilometers per hour. Not 40kph, as somebody had mentioned.
   It's made and adapted from a bike frame.
  The small solar panels are for the blinkers, not for recharging the batteries.  There are no pedals to recharge the battery with.
  So, guys. Not free energy?  Or is it?  Nothing in life is free, except for life itself. 
  But, I'm sure we haven't heard the last of this.

I have already mentioned this in this thread, but here it is again in case anyone missed it.
I think at least one of the students are supposed to be showing their R-Walker bike in Bucharest, Romania which
takes place from Thursday May 14 to Monday May 18, for the world final Informatrix robotics competition.

Edit: 
Confirmed. Victor Ricardo Garcia and his teacher are in attendance at Informatrix in Bucharest

Why does an electric bike that recharges its own battery while running, need solar cells for the blinkers?

The solar cells shown in the video are quite small and may come as part of the head light assemblies.
In the video, they are mounted right above the small head lights, so they do seem to be associated with the head lights.

Yes, but TK's question still applies.  We are presented with a device that supposedly self-generates propulsive power of well over 100W.  Why does it need solar panels to recharge the batteries for a couple of Watts to headlights?  Why not just take a couple of Watts from the 100W+ propulsion power source?

  There must be a good reason. Like, to avoid draining the main battery's charge, while driving at night, with the lights on.
  We'll know if this is a hoax, or not, soon enough.
  But, I have a feeling that it's no hoax, and I do understand what is being said in the video. 
  Although this is just their first prototype, and probably is not a finished product, as yet.

The pieces that they have are suitable to a regenerative braking system.  The pictures do not show anything that I can see as a control electronics box.  So what it may be is that they have something as simple as the motor connected to the battery in parallel with the super capacitors.  In such a case they do not have any kind of power converter.  If the design is that dirt simple, then it would make sense that they would just go buy some headlights that they can bolt to the handle bars.  Also in such a case the 2000 rpm comments would make sense:  When the motor generator voltage is greater than the battery voltage the motor drives the battery braking the scooter.  At lower rpms the motor draws current from the battery, but generating less and less torque as the generator voltage rises towards the battery voltage.

We so far have very few technical details about how this bike is supposed to function
as a 'self sustaining' bike. For all we really know at this point the students could be recharging
the battery using portable solar panels or whatever when the bike is parked. The news stories posted so
far may have been misleading to some extent or other. Regarding the head lights and small solar panels, since this was a
green project by the students, they may just have wanted to show that parts of the bike can be independently powered by
solar power to reduce main battery load, or whatever.

Hi NickZ. Nothing anywhere has suggested this is a 'hoax'. The students actually recently won first place in a
robotics competition in Spain with their R-Walker bike. ;) What is still uncertain is what exactly the
students meant by the bike being 'self sustaining'. That could possibly mean anything from regenerative braking
and possibly the use of portable solar panels, to who knows what else. :)

  We'll if it's not a hoax, which I doubt, and it's based on regenative braking involved to maintain the charge on the battery.
Then the led lights and solar cells are probably purchased as a bike lighting system addition, for night driving.
The lights may have nothing to do with the main battery. But, even if if the tiny solar panels were to add charge to the main battery,
as well, there's nothing wrong with that.
 
  It reminds me of what we did as kids, taking a bike frame, adding some smaller wheels to it, and placing a small gas motor in
the center of the frame. It was a lot of fun.  And it would go over 30mph.
 The limit now for electric bikes, scooters, and mopeds, etz... is no faster than 30mph.
 
  Main thing was, that with this new approach, the prototype has "run for 5 month without discharging the battery".
  Take it for what it's worth. To me this is one interesting project, with far reaching possibilities.

Nature did not suddenly change yesterday.  Going 10mph up a mild 1% grade with a 50lb bike and 150lb rider amounts to lifting 90.9kg by 0.0447m/s, requires 39.8W mechanical power over and above friction losses.  That power has to come from somewhere.  A small sealed lead acid battery of the kind they show has around 85Wh storage.  So, with no friction or power conversion losses it could support the scooter going about 20miles on an average 1% grade.  Or two hours endurance.  That boys and girls is all you get.  If they regeneratively brake going downhill or coasting, they have to spend the energy getting up to speed or going up the hill.  There is no free lunch.

  As I didn't hear anything about the brakes being involved in the recharging process, it may be that they have a found way to regenerate the battery charge, even without having braking be involved. And, it may not be the right time for them to spill the beans, about it. As it all depends on how the battery is being recharged, while the vehicle is running.
  I'd love to be the first on my block, with one of those. Ha!

Recharging the battery from the motor uses the motor as a generator and the entire process places a mechanical load on the wheels.  It is regenerative braking.  A rose by any other name is still a rose.

I do not recall anyone here suggesting that this is a hoax or fraud.  It is obviously some sort of miscommunication due to translations and a real
lack of any details of their device.  All I have ever said is that it can not do 60km/hour and run for 5 months without recharging the battery as some of the translations have claimed so, there is obviously something misunderstood by the reporters.
