The launching of the ALTER BIKE (under the brand Gitane), a new concept of electric bicycles which relieves the user from most of the usual constraints of electric mobility

No plug-in infrastructure for charging is necessary, lighter weight and range availability on demand.

Presented on the 30th of May 2013, at the 20th Congress of “Le club des Villes et Territoires Cyclables” in Nice, ALTER BIKE (brand Gitane) is a real revolutionary innovation in electric bicycles. A partnership of three French firms – Cycleurope, Pragma Industries and Ventec – have developed this new bicycle concept with the target of being a highly ecological and economical means of powered transport.


Nice (France), the 30th of May 2013

In line with the enthusiasm observed these past years around cycling and especially around high added value products such as electric bicycles, ALTER BIKE is the first industrialized bicycle in its category to use a hydrogen fuel cell, thus solving two major user constraints as underlined:

  • Ease of operation, thanks to the instant replacement of ready-to-use energy cartridges thus eliminating any plug-in socket requirement and therefore no recharging time.
  • Due to this new technology, the range flexibility of the electric bike adapts to the user requirements in a clever way. Each fuel cartridge conditions the distance and therefore the user takes the necessary quantity depending on the daily trip.

This breakthrough has been developed and adapted to bikes, thanks to the association of the three French enterprises:

  • Cycleurope, designer, manufacturer and distributor of bicycles, the firm is a European leader on the electric bicycle market;
  • Pragma Industries, innovative company that develops a new concept of hydrogen fuel cells particularly suitable for portable applications and electric mobility;
  • Ventec, a firm specialized in the conception and the production of BMS (Battery Management System) for lithium batteries. Ventec is the leader in this field in France.

The ALTER BIKE innovation relies on a group of technological solutions including a new breed of hydrogen fuel cells, hydrogen chemical storage in recyclable canisters, as well as hybrid electronic architecture balancing power needs between the Li-ion battery and the hydrogen fuel cell.

Jérôme Valentin, CEO of Cycleurope Industries France comments “We welcome the partnership with Pragma Industries and Ventec, as it complements our technological expertise and know-how in the bike industry. This innovative platform opens immense opportunities in the fast growing field of electric bikes, which is one of the key strategic segments we have chosen to invest in.”

Pierre Forté, CEO of Pragma Industries states “Pragma is proud to work with Cycleurope and Ventec to design the first product that will integrate our patented open-cathode fuel cell technology. As our fuel cell is specifically designed for mass manufacturing, coupled with recyclable fuel cartridges, it brings a great added value to the industrial strategy of our partners“.

We believe that the combination of a fuel cell and a lithium battery provides the best of both technologies: power and range and this bike is true proof” said Cedric Loubiat technical director of Ventec. “With the collaboration of Cycleurope and Pragma companies, we have designed and assembled in a record time this complex and extremely innovative prototype.”

The objective is to market the Alter Bike early 2014 aiming at public organizations and in 2016 towards the general public.

5 Ways That CPR Training Can Save Lives

5 Ways That CPR Training Can Save Lives

CPR dates back to the 1700’s if not further back. In 1740 CPR i.e. mouth to mouth resuscitation was recommended by the Paris Academy of Sciences for victims who had drowned. The reason why it worked is because it helped deliver the body a fresh dose of oxygen while at the same time the pumping action helped to get water out of the body. Today, CPR is down to a technique that can be taught, learnt and applied by regular people in order to save lives. There are also various types of CPR, and each one is effective in a particular situation. A trained person should be able to identify the situation and then use the right corresponding CPR technique.

CPR for cardiac arrest victims

CPR for cardiac arrest victims mainly begins with a series of chest compressions. These chest compressions are to mainly try and massage the heart into restarting. However, if this does not work initially then an AED will have to be used. An AED that is designed for ordinary people comes with a complete list of instructions. These instructions guide the person through the steps required to place the pads on the right area and then shock the victim. The victim then needs to be given a series of rescue breaths soon after. On the spot or immediate CPR can double the survival chances of a cardiac arrest victim.

CPR for people with asthma

It is important to understand that CPR does not cure people from asthma, it is also not an alternative to regular asthma medication like using a prescribed inhaler. However, CPR can help if the asthma victim’s heart has stopped. Many times victims will collapse because of a lack of oxygen. If the asthma victim does not get enough oxygen after they have been resuscitated their heart will stop again. Also asthma causes the airways to swell shut, which is what makes CPR even more difficult.

The first step to helping an asthma victim is to clear their airways and start with mouth to mouth resuscitation. The airways may have to be opened up using a breathing tube or the breaths will not be effective. That said the sooner the victim gets to a hospital the better their chances of surviving because CPR can just keep them alive for a short amount of time.

CPR for drowning victims

Drowning victims need to get CPR within five minutes of being rescued since with every minute their chances of survival plummets by 10%. Performing CPR within the first five minutes will require that the airways of the victim be cleared. This will require that the jaw-jut technique be used. Then the person’s nose will have to be sealed with the pinch before covering their mouth with yours and blowing. Blow every two seconds. If the chest does not rise during your blowing then you need to check for obstructions in the airways and try again. Also check for a pulse every few seconds.

When CPR is delivered with defibrillation

When simply chest compressions are not good enough defibrillation will need to be used. Defibrillation devices are used to restart the heart’s rhythm via an electric shock. In most domestic or regular use units the shock is within a certain limit just so that the inexperienced non-professional does not end up doing more harm than good. The most common use of these devices is after it’s established that breaths and chest compression is not going to work. Also, this device is best used in cardiac arrest victims or victims that have no pulse.

At times CPR will follow directly after an electric shock has been administered in order to get the heart going. Multiple attempts at restarting the heart will be required in order to help save people on average.

CPR by a paramedic crew

Paramedics have an array of devices and techniques that they use based on what type of victim they are dealing with. Much of the CPR they do involves chest compressions and at time other methods will be used to give the victim a chance to stay alive long enough to get him or her to the nearest hospital. According to HealthCorp these techniques despite being able to save lives requires experience and extensive training but it’s a lot more successful at helping save people than regular CPR.

Only about 15% of the energy from the fuel you put in your tank gets used to move your car down the road or run useful accessories, such as air conditioning. The rest of the energy is lost to engine and drive line inefficiencies and idling. Therefore, the potential to improve fuel efficiency with advanced technologies is enormous. With an Electric Car it costs just $2.00 per 100kms with MUCH more performance than with petrol at $20.00 per 100kms.
