WHITE PAPER ON ELECTRIC BIKE

This article is written by the site www.veloelectriquefrance.fr

Editor : the August 18, 2016

The electric bike meeting in France a logical progression and natural and a great interest of consumers.

The majority of European countries have already adopted and the number of electric bikes sold in 2015 is close to 3 million because it will become in a few years the means of transport most used and the least costly, while participating in the well-being and health of the cyclist.

The strengths and the benefits are many and the upward trend in sales of EAB is expected to continue, but we are still very far from our European friends, Belgian, German and Dutch.

The French make the use of the bicycle, a sport activity and recreation, The electric bike will become in the next the privileged means of transport of the French. The problems that we encounter today in all the cities, lack of parking space, multiple axes and avenues that will be closed to traffic, congestion ; traffic difficult, not to mention the cost of maintenance.

The electric bike allows you to move easily without effort and moreover to do real economy, contributing significantly to the reduction of pollution while enhancing his physical condition (According to an English study, cycling is the physical activity more effective for weight loss).

The evolution of batteries and technology are factors which will enable us to make the long trip, some electric bike have a range of more than 140 km (new battery is expected in 2017 will exceed the cap of 200 km).

According to the polls, The only sticking point today, French remains the price.

Actually it is necessary to count between 1300 and 2000for an electric bicycle of good quality,

We will present in this article, the attention points for the purchase of a VAE).

If we look more closely, the average price of 1500€ is not expensive for consumers, because in reality if one takes the cost over 3 years is€ 40 per month,

For the car : the low estimate is 500€ (Fuel + Insurance + maintenance) and 500e on 3 years for the acquisition, not counting the PV, etc ...

For the motorcycle, it is estimated at 150€ (Fuel + Insurance + maintenance) and 150e about 3 years for the acquisition.

 

We will develop in this book, the following guides :

The operation of an electric bike

What type of battery and what is its autonomy

Registration and the law on the VAE

Functioning of a electric bike

Fonctionnement d'un VAE

The electric bike called a Bike or Electric assist V. A. E does not work like a motorcycle, the electric bicycle does not roll alone, but assisted by human effort. This is the pedal that causes the electric motor and aid to more than 80% the user in his effort.

This mode of operation is imposed by the French legislation, you will find in other countries, some electric bicycles to attend 100% and that works like a motorcycle.

 

The starting pedal is mandatory according to the French legislation for the V. A. E is considered as a cycle and not a moped. It must also meet other requirements for a V. A. E is considered a bicycle and not a moped :

The engine should be triggered as soon as there is human effort and must stop when the user stops pedaling ;

The engine must not exceed 250 Watts of power ;

As soon as the speed of 25 km/h is reached, the engine must stop.

An electric bicycle is equipped with an engine of 180 to 250 Watts, and a battery 24 or 36 Volts. To assist pedalling, the electric motor switches on automatically when you pedal. He cut himself off when the pedaling stops.

This allows you to arrive with little effort at a speed of 25km/h, and climb uphill very easily. To recharge the battery, it plugs into a power outlet, a classic home or office.

Normally, the level of assistance the electric motor should be able to adjust, whether we choose to be strongly assisted in the move or not. The battery on it can normally be recharged with an electrical outlet, at home or at the office.

 

The electric bicycle is a conventional bicycle to which are added:

- an electric motor which can be located in the front or rear wheel, crank, and sometimes deported by belt. The law limits its power to 250 watts and speed up to 25 km/h,

- a battery which, depending on the technology used, brings an autonomy more or less important. A battery charger is provided for the power sector.

- an electronic controller that can regulate the different components (built into the battery pack on the picture)

- a control box on the handlebar, which is not necessarily present according to the models, and which allows the user to modulate its assistance, to know its mileage...

  

What type of battery and what is its autonomy

Types of batteries for electric bikes

The battery is the most important component of the electric bicycle, it is characterized by its technology and its power.

They exist 3 types of batteries : Ni-MH, Li-Ion, Li-Po

Lead-acid battery

They are no longer used on electric bicycles from the bottom of the range. They are much more heavy between 5 and 6 kg compared to 1 to 2kg for the other types.

They have a shorter life between 250 and 350 cycles of load.

Less expensive, but also much heavier and more difficult to recycle than others. A

Battery nickel-metal hydride - Ni-MH

This battery is susceptible to the memory effect, unlike other technologies, Lead, Li-Ion or Li-Po. They recycle well, but can't stand the overload and require a charger that is suitable. They are sensitive to self-discharge. The Ni-MH batteries are capable of around 500 charge cycles.

  Lithium battery, Li-Ion

These are the ones that are the most frequent, it pésent average 1.5 kg but do not have a memory effect and have a superior performance to lead acid batteries or NI-MH batteries. They recycle well. The lithium Ion batteries can withstand from 600 to 1200 charge cycles for the best.

  Lithium - ion polymer battery Li-Po

They weigh in around 500g, they do not have memory effect and have a performance equivalent to the Li-ion batteries. They recycle well. The batteries in li-Po support from 600 to 1500 charge cycles.

A battery a chemical element that deteriorates in time. Follow the manufacturers recommendations to prolong the life

 

The batteries of the bikes electrical represent 30 to 50% of the price of the bike. The technology of the battery influences a lot the performance of the EAB, but also its price.

 

The autonomy of the batteries of electric bike

The battery gives the bike its autonomy and its power. The performance of the battery is expressed by the combination of the voltage expressed in Volt (V) and its capacity expressed in Ampere-hours (Ah).

 

Some figures on tests done with a mountain bike brand, with a motor crank, and a battery Li-Ion 400 Watt-hours.

Flat course : autonomy of more than 100 km up to 110 or even 120 kms. (less than 3.8 Watt-hour per km)

Course with a terrain of small hills : a range of about 85 to 100 kms. (3.8 to 4.5 Watt-hours per km)

Course quite hilly (for example, with climbs of 4 to 7 kms more than 5% : Range of 75 to 85 kms (4.5 to 5 Watt-hours per km)

Finally, we can simplify by saying that 100 watt-hours are used to navigate between 20 and 30 kms, depending on the context.

 

To calculate the power of a VAE in Watts, multiply the voltage of the battery expressed in volts by the current expressed in amperes. For example, a bike 24V 10 Ah is 240W. In the case where the bike has a power greater than 250W as, for example, 36V 8Ah = 288 W, it is electronically limited and the surplus power will fall back on a greater autonomy of the battery.

  

Registration and the law on the VAE

The european directive 2002/24/EC sets out the criteria for what an electric bike can travel on the public highway :

 

The assistance should be done only if the cyclist pedals, and the cutting off of the pedal. However, it is allowed to put in place a start-up assistance without the need for pedalling, but must not exceed 6 km/h.

 

The engine power must not exceed 250 Watts

Important : If your electric bike is not responding to any of these features, it classifies it in the category of mopeds and requires a homologation special

The engine must not exceed 250 Watts of power ;

As soon as the speed of 25 km/h is reached, the engine must stop.

An electric bicycle is equipped with an engine of 180 to 250 Watts, and a battery 24 or 36 Volts. To assist pedalling, the electric motor switches on automatically when you pedal. He cut himself off when the pedaling stops.

Wearing a helmet is not mandatory, and it is not necessary to have any license.

  

It must Ensure that its electric bike

The electric bicycle is still considered a bicycle as soon as the following conditions are met :

• the engine must be cut off if the cyclist does not pedal more, brake or exceeds 25 km/h

• the engine must operate in case of use of the pedals

• the power of the motor must not exceed 250 watts

 

 

If you have an insurance for civil liability private life included in your home insurance, your electric bike will be auto-insured. So be sure to take a look at your contract !

Of course, some insurers offer additional safeguards against theft. So don't hesitate to ask about it !

Be sure finally, the registration of your vehicle because, if such is not the case, your insurer can refuse to cover you in case of an accident.

  

What electric bike and for what use

It is important to choose their electric bicycle as a function of use, the number of kilometer to browse by month, the type of way to go, the budget, dimensions and the room you have to stow it.

THE after-sales Service and warranty on electric bikes

The after-sales service on electric bikes

We believe that the sale of electric bicycles will become more common as it is already the case in other European countries, namely, that the sales on the internet will more and more develop.

In effect, the shops, however, remain limited in the choices of models and brands offered, on the other hand, they will often encourage you to take a model even if the latter is exceeded a point-of-view technology.

We speak, of course, electric bikes brand, and greater than 1200 €, The sales on the internet offers benefits, such as price, the ability to have access to the latest models, a greater diversity of brands and power.

You're going to tell me and the SAV.

The internet sites that respect have such as the shops at their repair center, which is often more efficient because technicians are trained to manufacturers and in addition they are more spare parts in stock.

The battery are 2 years warranty, the component such as the support, the front derailleur, suspensions, ... are 2 years warranty, the bike frame is guaranteed 5 years.

 

Manufacturers distinguish between the guarantee on the part of the cycle (the bike itself) of the engine and the battery. The warranty periods range from 1 to 5 years generally on the part of the cycle and from 1 to 3 years for the motor and the battery. Some manufacturers give a number of load cycles is guaranteed for the battery.

 

IMPORTANT : you must recharge your battery every month even if you do not use your electric bike.

The weight of electric bikes

This article is written by the site www.veloelectriquefrance.fr

Why the electric bike is heavier

 

This article aims to inform you about the weight of electric bikes.

The electric bikes are much heavier than bicycle classic, and this for several reasons.

  1.      Equipment such as the support, the crank.
  2.      The battery, which weighs often the models between 1.5 and 2.5 kg.
  3.      All the other components like the frame, the stem quality is better than the conventional bicycle and therefore heavier

Has less to pay the electric bike very expensive such as carbon or aluminium lightweight.

The role of the assistance is to ease pedaling so as to make it a very easy.

The weight on an electric bike is not a handicap it is necessary to take into account, this is not the weight of the bike, but the set of parameters (battery, assistance, engine).
