Electric bike guide


Advantages

The electric bike is undeniably the ideal means of travel for short trips (between 5 and 15 km), it allows to move very easily, low cost, and without counting the benefits and benefits to maintain his physical condition. In practice, you leave very easily after each stop at a traffic light. You pass the coasts without effort. You can easily carry a child on a seat behind you. Maintenance is very inexpensive. The sensations while driving are generally considered very pleasant.
Limits

The only limit that can be found is actually the battery, but the technology in this area continues to evolve and realize batteries with very high autonomy (up to 150 km and 300 km in a year.

In practice, when the battery is discharged, you end up with a bike weighing a dead donkey, between 20 and 30 kg. Choose a lightest model possible if, to store it at home, load it in a TER or park it at work, you have to cross bike steps by hand, or maneuver in a narrow corridor.
The flight

Another disadvantage is, of course, the risk of being stolen. But you have the option to insure for less than 100 € per year your electric bike with specialized insurance like cycleassur. Ideally, remove the battery when you park it. A VAE without battery has no interest. Otherwise, hang your bike with one or two strong locks.
What price for an electric bike

Beware of electric bikes that are offered below 1300 €, the main components of an electric bike that are battery, motor, assistance are very components that cost individually between 300 and 400 € minimum and therefore very often , the models proposed in this price range have a very limited life (less than 2 years) besides their performance which are very poor.

Between 1,500 and 3,000 €, you will find either well-equipped and well-equipped urban bikes (disc brakes, high-performance lighting, aluminum frame, pedal motor, proportional assistance, elegant design, etc.), or electric bikes.


Beyond 3 000 €, you will have a high-end mountain bike. "Speed-bikes" have also appeared in this price category. Capable of driving at 45 km / h, they are no longer bicycles within the meaning of the regulations: they are subject to the same obligations as motorized two-wheelers, with helmet, registration and compulsory insurance.
Which Battery

Capacities are expressed in amp-hours, watts and volts, which is not always very clear. A bit of technique: the amperage is the electricity available in your battery, and the voltage to the voltage of your electric motor. By multiplying the amperage by the voltage, you get, in watts-hours, the amount of energy of the battery when it is full. In theory 360 W, the power you can actually count on a 10 × 36 battery runs around 250 W / h. It's enough to climb any coast without effort. In summary: the higher the amperage, the greater the autonomy is important, and the higher the voltage, the more the driving will be "easy".
autonomy

Serious manufacturers give wide ranges, "50 to 150 km" type. It's not precise, but it's honest. It is impossible to say exactly how far a given battery covers. Too many parameters come into play: your weight, your strength, wind, tire inflation, terrain, etc. To give an order of magnitude, let's say that a battery of 36 V-10 Ah new can cover several tens of kilometers at a pace between 15 and 25 km / h. Over time, the performance will deteriorate, but you can count on several hundred cycles of charge and discharge if you have a famous brand battery: Bosch, Yamaha, Panasonic, Sram, Shimano, Beaufort Smart BMS ... The cost of charging on mains is negligible, of the order of a few cents for 50 km.
Engine

It can be located in the rear wheel, in the front wheel or in the pedal, which is ideal because the bike is well balanced. Placed in one of the wheels, the engine can hinder the repair in case of puncture. If installed in the hub of the front wheel, it will tend to weigh down the steering and make the bike a little unstable. On an ATV, the engine is often in the back because it promotes propulsion.
Energy recovery

Some manufacturers highlight devices to recover energy for the battery in downhill and braking. The idea seems logical and attractive, but the performance is disappointing, especially on the flat courses, where much of the energy spent is used to overcome the resistance of the air and can not be recovered.


Which mode of assistance

be located in the rear wheel, in the front wheel or in the crankset, which is ideal because the bike is well balanced. Placed in one of the wheels, the engine can hinder the repair in case of puncture. If installed in the hub of the front wheel, it will tend to weigh down the steering and make the bike a little unstable. On an ATV, the engine is often at the rear, because it promotes propulsion.Fet it buy his electric bike on IntenetToday, behind all the electric bike sale websites are hiding from the market leader or power plant. purchase which have advantages and are in relation of strength to obtain reductions that can not have independent or shops. On the other hand, the sites internets ensure the SAV on all France (which is our case) by through their network of repairers. And finally the charges on the internet are less expensive than for a shop and therefore, the sites have more latitude to propose important discounts to their customers.
