How to change the speed limit on your Furo X

As you know, when shipped to you, your Furo X‘s top speed is electronically limited to 25kph due to EU legal requirements for the bike to be road legal. Once the FX goes over 25kph, the motor automatically cuts off. However, you might want a different speed limit if you are using your bike in an area with different restrictions (e.g. USA 32kph), or in the case where you don’t use your FX on public roads (e.g. on private property). This guide will quickly show you how to change the speed limit on the KD21C key-disp display which equips the Furo X.

 

 

 

1 – Switch on the battery and press and hold the mode button to switch on your screen.
Switch on your ebike display
2 – Once your screen is on, press and hold both the “+” and “-“ buttons to access the general settings.
Enter the general settings
3 – Press and hold the “M” and “-“ button to access the system settings
Enter the system's settings
4 – Once in the system settings, tap “M” to scroll through the different settings. The speed limit setting is marked “LS”.
Access the speed limit setting
5 – Use the “+” and “-“ to adjust the speed limit which can be seen in the bottom left corner of the screen.
Adjust the speed limit
6 – Once you have selected a new setting, press and hold “M” to save and return to the starting screen.
Save and return to the starting screenLegal 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.

Lithium-ion Batteries vs Hydrogen Fuel Cells in Electric Vehicles

Today, most electric vehicles use batteries, often based on Lithium-ion or Lead-acid chemistry. These batteries allow storing energy that was produced away from the vehicle and subsequently use that energy to create mechanical motion and make an e-bike, car or motorcycle move forward. Hydrogen Fuel cells, a rather old technology, created in 1839 by Sir William Grove and refined through the years, also allow storing energy in the form of hydrogen to power electric vehicles. Like a battery, a fuel 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 of 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.

 

Hydrogen Fuel Cells vs Lithium-ion Batteries - Detailed functioning of a Hydrogen Fuel Cell

 

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 fuel through processes that are quite expensive and energy-consuming.

 

Hydrogen used in fuel cells has the 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.

 

Detailed functioning of a Hydrogen Fuel Cell

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 e-bikes and other vehicles.
