5 Benefits of electric bikes

Electric bikes are quickly becoming a modern phenomenon, and it’s easy to see why. They provide many advantages over other modes of transport, both for the rider and the environment; it’s why we decided to develop our own range. The most obvious benefit being that the electric motor allows you to ride further, faster, and for longer than a normal bike – regardless of your fitness level. Read on more electric bike benefits below:



1. Better commutes

However you usually get to work, there’s a good chance that your journey can be improved by using an electric bike. Using a regular bike will often leave you sweaty and out of breath by the time you arrive at the office, especially if you have steep hills to climb or it’s a particularly windy day. With an electric bike, you can take advantage of the electrical assistance to make hill climbing virtually effortless, to give yourself a boost if the wind is against you, and make you generally need to expend less energy than you otherwise would. Never show up flustered and out of breath for your morning meetings ever again. Likewise, a brisk bike ride home is the perfect antidote to a stressful day’s work.

If you usually drive or take public transport, then using an electric bike will give you some fresh air and exercise to start or finish your day. You’ll also avoid traffic jams, train delays, and being squashed into carriages like a sardine!



2. A cheaper way to travel

Aside from walking, every mode of transport comes with a cost, and over time these costs can add up. Using a car or motorbike is very expensive; you need to pay for the vehicle itself, tax, insurance, regular trips to a petrol station, and maintenance fees if your vehicle gets damaged. If you live or work in a big city, you may also incur costs relating to emissions or congestion (like London’s Congestion Charge). Public transport is also very expensive, with season tickets and travel cards costing up to several thousand pounds every year.

With an electric bike, you make a one-off payment and don’t need to worry about tax, insurance, fuel or season ticket expiry dates. Electric bikes are good for your health and your wallet. In fact, it costs just 20p to travel 150km with a Furo ebike!



3. Kinder to the environment

Now, more than ever, people are realising the environmental impact of our travel habits and want to find greener alternatives. Transportation is one of the largest contributors to global warming, so the need for alternatives cannot be overstated. Electric vehicles are one way to limit our reliance on fossil fuels, and electric bikes, in particular, require far less electricity than electric cars or electric motorbikes due to their compact size and weight. Electric bikes are a sustainable transport method for the future.




4. Fitness benefits

The health benefits of cycling are well-known. It’s a form of aerobic exercise that gets your heart pumping and helps to lower blood pressure, improve sleep quality, can reduce symptoms of depression, and improve your overall fitness. The problem is, cycling is not suitable for many people. Many people find it physically challenging, especially in hilly areas or places with lots of traffic. Electric bikes assist the rider and take some of the strain, meaning more people can enjoy the benefits of cycling without the drawbacks. Cycling purists may say that it’s cheating, but we think that getting more people to cycle is a good thing.




5. It’s fun!

Last but by no means least, riding an electric bike is tonnes of fun. It’s almost impossible to ride a bike and not enjoy it, especially when you have an electric motor to give you a boost! Our bikes use the same power cells that Tesla uses in their Model S, so you’ll effortlessly glide around the city. Enjoy cycling alone or with friends and enjoy the great outdoors.

If you’re interested in joining the trend, then we recommend you take a look at our Furo X. It’s our most popular electric bike; it’s lightweight at just 15kg and folds to just 75x70cm, making it the perfect commuter vehicle. Its lightweight carbon fibre body and efficient battery system gives it an excellent range and gives you full control over your riding experience.

Electric Bike Battery: Best Tips for Long Battery Life

Batteries are a fascinating thing. Electricity transformed our society for the better, opening the door to wonderful advances in science, technology, and making our every day lives much easier and comfortable in the process. A notable example being machines such as electric cars, electric bicycles and electric scooters which facilitate urban life and daily movements while lowering pollution and our detrimental impact on the environment. However, electricity is quite hard to store. Today, the best commercially available way we have to do this, the best meaning the way with the most optimal balance between volume, price and energy delivery is Lithium-ion cells. You can have a look at our previous article on electric bike batteries to get a better idea of how they work exactly. Now, most of you will know that Lithium-ion batteries have a certain life span. Let me make this a bit clearer for you. As you store and extract power from your battery, the cells that constitute it do some work, heating up at the same time and slowly deteriorating, mainly due to increased internal resistance. When you read the quoted manufacturer cycle life of your battery, it only tells you how many cycles (fully charged to fully discharged) your battery can go through before reaching 70% of its original capacity. It won’t die at this point though, its capacity will keep decreasing linearly until the cells inside of the battery eventually fail after an indeterminate amount of time which will depend largely on manufacturing quality, maintenance and intensity of use.

Most modern Lithium-ion cells will have a cycle life of 500 cycles. This means that after 500 complete charges and complete discharges of your electric bike or electric scooter at their standard charge and discharge rates, you will get about 70% of the capacity you had during your first use. Charging or discharging faster will significantly decrease this.

However, there is a trick to multiplying this cycle of life significantly. First of all, there is the obvious more moderate use. You usually cannot do much about charging speed as this is provided by your electric vehicle manufacturer through their charger, but most of the time these are slow enough to preserve the integrity of your battery. On the other hand, you can make sure you reduce your average riding speed and the intensity of your accelerations and electric decelerations. On top of giving you more range per charge, this will also increase your cycle life by a non-negligible amount.

The optimal operational and storage temperature for modern Lithium-ion batteries, whether in electric cars, ebikes or escooters is 23°C.

Storing your electric bike battery in cooler places will usually be better than in warmer places. However, using your battery in colder environments will reduce your immediate capacity much more than in warmer environments, based on the 23°C baseline mentioned above.

The absolute best thing you can do for your battery, and we are talking 10x improvements in cycle life, is to manage your charge and discharge levels. From our learnings at FuroSystems and my personal experience as an aerospace engineer specialising in advanced space systems, charging your battery in a way that keeps its cells at a maximum voltage of 3.9V and subsequently using only 50% of your battery capacity can take your cycle life from 500 cycles to 6000 cycles.

It is very important to note that every 10 to 15 cycles, you should conduct a full charge and full discharge of your battery to make sure that you do not lose any energy capacity due to memory phenomenons.

A practical example for our eTura and our Furo X which use a similar battery configuration would be charging your battery to 39V or four bars (almost 5 bars) on the computer and discharging it to roughly two bars on the computer. For the Fuze, that would be a charge to 50.7V and a discharge to 39V (can be checked on the computer, see user manual). If you are not a FuroSystems owner, you can usually divide the nominal voltage of your battery by 3.6 to get the number of cells in series in your battery and multiply that by 3.9 to get your recommended charge level. It is very important to note that every 10 to 15 cycles, you should conduct a full charge and full discharge of your battery to make sure that you do not lose any energy capacity due to memory phenomenons.

Eventually, it all depends on how you want to use your electric bike or scooter. You can either go full power all the time, make the most of if every day and have a lot of fun, keeping in mind that after 500 cycles you will be at roughly 70% of your original capacity. Or, you can pay attention to how you use your EV in order to maximise cycle life, which will also mean less range per charge.


Our Tips for a Long Electric Bike Battery Life

  • Store your electric bike battery in a cool and dry place between 15°C and 23°C.
  • Use your electric bicycle or electric scooter preferably between 15°C and 35°C rather than 0°C and 15°C.
  • Watch your average speed and the intensity of your accelerations and decelerations (when using battery regen).
  • Charge your battery to 3.9V per cell (roughly 75% capacity) and discharge down to roughly 25%, so a 50% discharge of your battery from 75% down to 25%. This could get you up to 6000 cycles of life. Of course, charging higher and discharging further will decrease this progressively until you reach your quoted 500 cycles under normal use.
  • Always make sure that you have one full charge and full discharge cycle every 10 to 15 charge cycles.
