In this article we will explain exactly what you should expect with regards to hidden costs when purchasing an ebike online.
First of all, it is important to highlight the fact that if you reside in an European country, the price you pay when purchasing your FuroSystems eBike(s) is the price displayed on our website, there are no hidden costs. We offer shipping and cover all VAT, import duties and taxes that apply to your country.
Now, what are these taxes exactly? When importing a bike you can expect to be charged the following: Value Added Tax, Import Duties and in some cases anti-dumping duties. Most of you are familiar with VAT, which revolves around 20% in Europe. Similarly, Import Duties, a tax levied at customs, are of 6% in Europe. So when purchasing an eBike which originates from outside your country or economic zone on a crowdfunding platform or website that announces that the VAT and duties are covered by customers, you can expect to pay an extra 1.2*1.06=27.2% on the retail value of your product. That’s an extra €400 on a €1,500 bike. Of course, these will vary depending on where you reside and where your product is coming from.
90% of the time, as with most manufactured products today, your ebike will be coming from China simply because of the costs you and your manufacturer can save doing so while still enjoying outstanding quality (China is not what it used to be, their output quality and experience are now world class, with some exceptions, of course).
The nasty one: anti-dumping duties
This is particularly relevant to ebikes manufactured in China. The interesting thing being that in a way, they all are today. When they are announced as not, most of the components are manufactured there and assembled in another country.
A few months ago, several big manufacturers went to the European Commission claiming that most eBikes importers and manufacturers (designing in Europe but manufacturing outside of the EU) were dumping in Europe, which means buying and retailing at prices way below what they should be and therefore killing local players. However, this does not make much sense, because as mentioned above, all eBikes, even the ones retailed by the “complainers” are mostly made in China but assembled somewhere else. In addition, Lithium-ion batteries, motors and high quality bike/ebike components are more or less the same price everywhere in the world due to the elevated costs of raw materials (Lithium, copper, etc).
Nevertheless, after undergoing some intense lobbying, the European Commission decided to apply a 83% tariff on all ebike imports from China. Not 10%, not 30%, not even 70%, 83% 🙂
This means that when purchasing an ebike from a company that imports or manufactures its designs in China, their import value becomes their actual value multiplied by 1.83. VAT and Duties then apply on top of this so the total multiple becomes 1.83*1.2*1.06=2.33.
You are reading this right, as a European, when buying an ebike manufactured in China on a website, crowdfunding platform or company that tells you that VAT and taxes are on you, you will most likely receive a bill of €1330 on an ebike you paid €1000 (133% the announced price in additional taxes).
Again, we want to insist on the fact that this is NOT THE CASE WITH FUROSYSTEMS, THE PRICE YOU PAY AT CHECKOUT IS THE PRICE YOU PAY FOR YOUR BIKE, NO HIDDEN COSTS.
Similarly, the US soon will soon raise their import duties on eBikes from China to 25%. All of this to say that when going through such a purchase, make sure that you are not surprised by an unexpected bill upon receiving your bike. You can do this by checking the company’s policy on VAT and import taxes as well as verifying the taxes that are relevant to you in your country. In some lucky places, these can be close to 0!
Don’t hesitate to ask in the comments if you have any questions!
For everyone else we have translated the section of the article that talks about us and our baby 🙂 :
“The weight of a bike is a guarantee of performance, but folding bikes are not really intended for time hunters. So, why save weight on an urban pedelec? Simply because once folded to be mounted in your apartment or transported in the corridors of the train stations, the Furo FX will be much more convenient than many competitors. Indeed, leaving aluminum for carbon, its frame is much lighter while remaining just as rigid. Result of the races, this folding ebike weighs only 15 kg or more than 8 kg less than the 2MEJ for example.
With its FX, FuroSystems has understood everything: a folding bike must be lightweight to be easily transportable when no longer on its wheels. For this, the English manufacturer has adopted the carbon for the construction of the frame. Result of the races, the FX weighs between 6 and 8 kg less than the competition, which is significant. In addition, it is a great ebike to use thanks to its powerful motor and 9 speeds Shimano transmission. The braking is easy to dose and the integrated turn signals reassure even if motorists unaccustomed to this type of equipment on a bike do not always understand them.”
Over the last few months we have been developing accessories for the SIERRA and the FX. A complete set of fenders for the SIERRA, able to withstand the toughest of environments and conditions, and a complete set of fenders, a rear luggage carrier and a kickstand for the FX to make sure that your commute and city journeys are as smooth and convenient as they could be, while not impeding on the folding process and storage space. The thing is though, unlike most of the other guys out there, we are going to offer these to you with all new bikes orders for free, because we believe they are part of your FuroSystems ebike experience.
Although we are accelerating our production rates considerably, more and more of you are getting in touch to get your hands on a FX or a SIERRA. The faster you order, the earlier we can guarantee you will receive your ebike. We will strive to continuously accelerate our factory output while never compromising on quality or performance, you can be sure of that!
So, when we tell you the range of the FX is 45km at a normal pace, you will get 45km or MORE at a normal pace on the FX, and so on for the FX MAX, SIERRA and SIERRA MAX. However, over the last few months we noticed that a few actors on the market (we won’t cite any names), were lying and inducing you in error with regards to the announced range of their bikes. Therefore, in order to really help you understand what you get when you purchase an electric bicycle we decided to write this small guide on how to calculate the real range of your bike and bypass the lies of some manufacturers.
The range of your ebike depends on a few characteristics. First, the energy contained in your battery. This is not your battery’s voltage on its own, nor its Ah capacity on its own, but the two multiplied together: Voltage x Capacity in Ah. This gives you the energy carried by the battery of your bike in Wh. For example, the FX’s standard battery carries 314Wh which corresponds to a potential consumption of 314W for one hour or 157W for 2 hours and so on.
Most ebike motors for road use have a continuous power of 250W, a peak power of 500W and a max speed of 25km/h. This means that upon accelerating, and for short periods of time, the motor will pull up to 500W of power from the battery, let’s say for a maximum of 10 seconds after which it will pull a constant 250W until the bike reaches 25km/h. Going back to our Physics of ecycling article, we can calculate how much power is consumed at 25km/h for a person of 75kg on an asphalt road:
We get a drag of 20N and a rolling resistance of 0.38N. This means that when riding your ebike at a constant speed of 25km/h you have to compensate for about 20.38N of force acting against your forward movement. Power is equal to force multiplied by velocity and 25km/h corresponds to approximately 7m/s. This gives a necessary power consumption of 142W to maintain this speed of 25km/h. Now, although part of the magic of bicycles is being able to enjoy great free wheel, which allows to ride power free without decelerating too fast, all periods of acceleration consume up to 500W. In addition, during these periods, the bike’s speed is lower than 25km/h. We have found through multiple tests and experiments that a factor of 20% represents well these losses.
Eventually, we can write that (Capacity (Wh) * Velocity (km/h)) / (Power Consumed (W) * Loss Factor) = Expected Range (km):
These values depend on your weight, style of riding and environmental conditions (temperature, assist level, acceleration, free wheeling, etc) but give a very reasonable approximation of what to expect. We are working on an online calculator, taking all these variables into account, that will be available on our website very soon. In the meantime, this will give you a very good idea of what’s real and what’s not. For example, a battery capacity of 220Wh will only give you about 32km at an average pace, not more like some would like you to think 😉
Legal notice: You must comply with your local regulations to ride your e-bike on public roads, increasing the speed limit over 25kph in the EU will make your e-bike illegal to ride on roads without a license and registration. The limit should only be increased over 25kph for off-road use or in the case where your local regulations allow it.
Like a battery, a fuel cell cell harnesses a chemical reaction to produce energy in the form of electricity. More specifically, Hydrogen fuel cells generate electricity, water and heat from hydrogen and oxygen.
Fuel cells consist in an anode and a cathode surrounding an electrolyte called a synthetic polymer membrane which separates hydrogen and oxygen while only permitting the passage of certain ions (H+ or protons). Hydrogen atoms enter the fuel cell at the anode where they are stripped of their electrons. These electrons travel through the vehicle’s circuit to the cathode in the form of electricity. The positively charged hydrogen atoms (or protons) travel through the membrane to join with the oxygen and the electrons in order to eventually form water. Each individual fuel cell produces relatively low amounts of current and voltage and, like lithium-ion cells, therefore need to be stacked together in series and in parallel to reach the target voltage and max current required by the vehicle they are powering.
The beauty of hydrogen fuel cells is that you get electricity, heat and (potable) water as outputs with hydrogen and oxygen as inputs. Oxygen is abundant in the atmosphere while hydrogen is the most common element in the universe. However, hydrogen tends to bond very easily with other elements. Therefore, it has to be artificially isolated before being usable as a fuel through processes that are quite expensive and energy consuming.
Hydrogen used in fuel cells has an energy to weight ratio ten times greater than lithium-ion batteries. Consequently, it offers much greater range while being lighter and occupying smaller volumes. It can also be recharged in a few minutes, similarly to gasoline vehicles. However, Hydrogen fuel cells also come with a lot of drawbacks. First of all, hydrogen is mainly obtained from water through electrolysis which is basically a reversed fuel cell and takes electricity and water to produce Hydrogen and Oxygen. The source of this electricity can range from renewables to coal depending on where you are in the world, hence hydrogen extraction can be very clean or dirtier than a typical gasoline car. Nowadays, sadly, it is more likely to be the latter simply because of the way the majority of the electricity is produced on Earth.
Other issues are that storing hydrogen as a gas is expensive and energy intensive, sometimes as much as half the energy it contains, and even more so when it is stored as a liquid at cryogenic temperatures. In addition, it is highly flammable, tends to escape containment and reacts with metals in a way than renders them more brittle and prone to breakage. Eventually, although it is everywhere around us, hydrogen is hard, dangerous and expensive to produce, store and transport.
Fuel cells can also only operate with water, not steam nor ice. Therefore, managing internal temperatures is essential and heat has to be constantly evacuated through radiators and cooling channels which add considerable amounts of weight. Restarting in cold temperatures can also be very complicated and impractical in locations that often experience temperatures below freezing point.
To conclude, hydrogen fuel cells offer a potentially very clean, energy dense and easy to recharge energy source for vehicles and other systems, but are currently complicated, expensive and dangerous to operate. In comparison, Lithium-ion batteries, although less energy dense and slower to recharge, are as clean, much cheaper, easier and safer to handle. More specifically, cylindrical lithium-ion cells like those used in the SIERRA and the FX are very stable and safe to use. In the future, once the technology is sufficiently developed and the drawbacks mentioned above addressed, hydrogen could be a great solution to increase range and decrease charging time in electric vehicles. But for now, lithium-ion technology is the best solution to offer very practical and high performance ebikes and other vehicles.
This is exactly why we have decided to add wireless turn indicators to all the FXs we ever produced, for free!
Every FX will now be equipped with a wireless remote attached to the handlebar and an indicator module in its portable lithium-ion battery. Simply click on the right or left arrow on the remote to indicate where your FX will take you next.

We are always available and very happy to help you, so if you have any questions or requests please don’t hesitate to contact us.
Let’s start with the protagonist itself, the ebike, here we will have a look at the SIERRA in particular. The SIERRA is made of a full carbon frame which has to be structurally strong enough to support the sum of your weight, the ebike’s weight with all its components, and the weight multiplication and shocks due to bumps and other obstacles on the road. In addition to all the typical bicycle equipment (disk brakes, gears, chain pedals, wheels, etc) the SIERRA’s frame also has to carry a motor, a battery, an electronic controller and a computer. These components are all relatively heavy with respect to the frame of the bike but remain light once you add your weight to the equation, even for the skinniest of you.
The SIERRA is equipped with a torque sensor which measures how much pressure you are exerting on the pedals. In turn, it sends a message to the controller which calculates how much power from the motor is immediately required. At the same time, the computer scales the controller’s calculations with respect to the assist level you are set on. Eventually, the controller which is connected to the battery, opens a channel between the battery and the motor and allows high power currents to flow in a certain pattern so as to activate the motor and power your ride.
This then makes you go forward and pick-up speed. We will now focus on what is happening once you have reached a speed of 20km/h and are accelerating by 1km/h per second or reaching 25km/h after 5 seconds on a flat asphalt road. According to the second law of Newton, all the forces acting on the bike and yourself while you move forward are equal to your total mass multiplied by your acceleration. This can be written:
The forces acting on the bike and yourself while you are moving are:
First of all, we can calculate the drag. In a standard relaxed cycling position on the SIERRA, your frontal area is likely to be 0.6m² and your coefficient of drag: 1.15. The density of the air at sea level is 1.225 kg/m3 and your velocity is 20km/h which is equivalent to 5.6 m/s.
The rolling resistance coefficient of bicycle tyres on asphalt is equal to 0.004, assuming you are 75kgs, the weight of the SIERRA being 20kgs, your total weight becomes 95kgs.
So the sum of the forces can now be written:
Also note that the sign of the forces in the sum depends on the direction these forces are acting. If they act in the direction of the movement, then they are positive, if they act in the opposite direction, they are negative. We can replace the variable with the values we calculated knowing that an acceleration of 1km/h/s is equivalent to 0.28 m/s²:
We know that the wheels of the SIERRA measure about 0.70m in diameter and therefore 0.35m in radius. We also know that torque is a force multiplied by a distance. Hence, the torque generated by the combined efforts of your legs and the SIERRA’s motor is 40*0.35=14 Nm. We can even get the total power by multiplying this by the angular velocity of the wheel, or the speed at which it rotates. We know that its perimeter is 2 * PI * Radius = 2.2m. As we are going at 5.6m/s, this gives 2.5 rotations of the wheels per second or an angular velocity of 15 rad/s (multiply by 2 * PI).
Hence, on a flat asphalt road, in order to maintain an acceleration of 1 km/h per second while being at a velocity of 20km/h, the total power needed from you and the SIERRA together is 15*14= 210W.
As the BOFEILI mid-motor of the SIERRA produces 350W of continuous power and more than 600W of peak power, at this cadence you will only be exploiting a third of the power of the beast. Depending on your assist level, you can either fully provide the 210W through your legs or entirely rely on the SIERRA, it’s your choice and that is the magic of electric cycling!
