Electric bicycles have the potential to change the game by reducing our reliance on cars and transforming the way we commute. However, while accidents are rare and shouldn't discourage you from investing in an electric bike, it's important to be aware of the potential fire hazards associated with large lithium-ion batteries installed on the bike frame.



Lithium-ion batteries offer many advantages that make them an ideal choice for electric bicycles. They can be charged and discharged hundreds of times, are relatively lightweight and compact, and contain lower levels of toxic heavy metals compared to many other battery types. Unfortunately, they are also highly flammable.



Why do electric bicycles pose a fire risk?

The lithium-ion batteries used in electric bicycles consist of two electrodes separated by an electrolyte. During charging or discharging, charged ions move from one electrode to the other.

The electrolyte in lithium-ion batteries is highly flammable. While this is generally not a problem, if the battery is damaged or overheated, the liquid may ignite. Once one battery overheats, adjacent batteries can also overheat (a process known as thermal runaway), and the heat and pressure quickly become uncontrollable, leading to an explosion.



To understand the reasons behind such incidents, TechRadar interviewed the Fire Protection Research Foundation, the research affiliate of the National Fire Protection Association (NFPA).



The project manager at the foundation explained that there are various causes for lithium-ion battery fires, including manufacturing defects, design flaws, improper usage (such as placing the battery near a heat source or exposing it to prolonged direct sunlight, which can lead to overheating), puncturing the battery in a way that causes a short circuit, and using chargers that are not suitable for the device.



These issues are not unique to electric bicycles—any device with lithium-ion batteries can potentially catch fire, as we have seen with smartphones, laptops, and electric cars.



Hoverboards, in particular, have gained notoriety. Since their popularity surged in 2015, the U.S. Consumer Product Safety Commission (CPSC) has reported over 250 incidents related to fires or overheating. Major airlines have banned hoverboards from commercial flights, and retailers like Amazon, Overstock, and Toys "R" Us have temporarily halted sales.



Electric skateboards are particularly susceptible because they are relatively new and lack design standards that mandate safety measures such as venting holes or separators that act as fuses and shut off the battery at certain temperatures. Unlike other devices with lithium-ion batteries, they have not undergone rigorous testing before being sold to the public.

The U.S. Consumer Product Safety Commission swiftly implemented safety standards for hoverboards, and although their use on airplanes is still prohibited, hoverboards quickly made a comeback on store shelves.



Electric bicycles have been around for a long time and have more mature standards. However, the Fire Protection Research Foundation explains that bicycles involved in fires often have poor manufacturing quality:



"According to anecdotal reports from some fire departments, such as the New York City Fire Department, many electric bicycle fires are caused by low-quality components (such as poorly controlled batteries or products not certified by independent testing laboratories)."



How to prevent electric bicycle fires

In addition to purchasing electric bicycles from reputable manufacturers that meet appropriate safety standards, there are some measures you should take to maintain your electric bicycle and prevent fires:



Read the user manual and follow the manufacturer's safety precautions.



Only use chargers provided by the brand that are compatible with the battery.



Avoid using power extension cords; plug the charger directly into a wall outlet.



Ensure you have smoke detectors installed in the area where you charge your electric bicycle, and that you can hear the alarm. For example, if you charge your electric bicycle in a garage or garden shed, make sure a smoke detector is installed there and can be heard from your house.



If your battery or electric bicycle is exposed to a flood, consider it permanently damaged and do not attempt to charge it. Dispose of it responsibly.



Thorpe also suggests considering recycling the battery of your electric bicycle after five years, regardless of its usage. "Electric bicycle technology is changing and advancing each year," he says.

Lastly, he warns against keeping old lithium-ion batteries at home—whether they are from electric bicycles or not. Instead, responsibly recycle them.



The National Fire Protection Association (NFPA) has its own safety tips for lithium-ion batteries, providing information on the safe use of products powered by lithium-ion batteries and guidance on what to do in case of a lithium-ion fire. It also offers specific guidance for electric bicycle owners, including:



Do not use aftermarket batteries.



Always use the power cord and power adapter specifically made by the manufacturer for the device.



Do not leave the electric bicycle unattended while charging.



Do not leave the electric bicycle charging overnight.



Store batteries and devices at room temperature. Extreme heat or cold temperatures can damage the batteries. It is also not recommended to leave them in direct sunlight.



Do not keep electric bicycles (or similar devices) in children's rooms.



Do not block main exits of buildings with electric bicycles (or similar devices).



What to do in case of a fire



Pay attention to the battery of the electric bicycle, as you may be able to identify warning signs before a fire occurs. If you notice strange odors, changes in shape, leaks, unusual noises, or excessive heat, NFPA recommends moving it away from anything that could catch fire (if possible) and calling the fire department.



If a fire does occur, do not attempt to extinguish it yourself; lithium battery fires are particularly hazardous as the battery casing can explode at high temperatures, posing the risk of flying debris. Instead, evacuate the area immediately and call emergency services.



By following the safety guidelines above, the risk of a fire is minimal, which should not deter you from purchasing an electric bicycle. However, if a fire does occur, leave it to the professionals.

When your electric bicycle needs a new battery, you have several options. It may take some time, but electric bicycle batteries do degrade over time. If your device is old and worn out, here are various choices to consider. Following the latest industry recommendations, which suggest replacing defective or scrap batteries with "authorized technically identical batteries," may not always be practical.



Batteries are the most expensive consumables on an electric bicycle, and replacing a battery typically costs several hundred pounds.The good news is that the quality of electric bicycle batteries is generally much better than in the early days of the industry. A two-year warranty is the minimum industry standard today, and the lifespan of high-quality electric bicycle batteries should be longer than that.



The bad news is that even with frequent use, electric bicycle batteries will eventually need to be replaced.




Option 1: Replace the battery within the warranty period


Electric bicycle batteries can fail in two main ways:



1. They may become unable to charge or provide power to the motor due to issues like faulty connections or a malfunctioning Battery Management System (BMS) chip.

2. Over time and repeated use, they may gradually lose capacity to the point where the range they provide becomes impractical. All lithium-ion batteries degrade with repeated use and charging. This, in itself, is not a fault, but it does mean that even the best electric bicycle batteries have a limited lifespan.



This is an important distinction because different battery warranties cover different battery faults. For example, ChamRider guarantees their own branded batteries to have at least 60% of the original charging capacity after 1,000 charge cycles . It is the dealer's job to determine the remaining battery capacity using diagnostic software. It widely quotes a guarantee of at least 60% of full charging capacity or 500 charge cycles within two years (whichever comes first) – although I was unable to find this information on their website.



However, many other companies may simply stipulate a two-year warranty. If your battery completely fails within two years, this should provide a clear solution, but if the available capacity drops significantly within that period, it may trigger various semantic debates.



Considering all the above factors, it is best to obtain as detailed a written battery warranty as possible from the retailer at the time of purchase. It must be said that finding a clear and detailed battery warranty on the websites of electric bicycle companies is a rather challenging task.



When does a battery degrade to the point of needing replacement?



By using an inline energy meter (such as this one), you can get a very approximate understanding of the capacity of your electric bicycle battery.



First, make sure your electric bicycle battery is completely depleted by using it until the battery is empty. You should know its rated capacity in watt-hours (Wh) – for more detailed information, refer to our battery article.



Now, charge it back up to full but use the inline power meter to measure the watt-hours consumed from start to finish (i.e., after the battery is fully charged).



Not all the electricity consumed by the meter goes into the battery. For example, the transformer that reduces the voltage from 240V to the voltage required by the electric bicycle battery is inefficient and loses some electricity.



Transformers vary, but a very rough working assumption is that 80% of the power from the socket ends up in the battery.

It's best to repeat this exercise a few times to get an average reading. Clearly, this method has its limitations, but it should at least indicate any very significant shortcomings in the battery's capacity and allow you to monitor it over time. If you notice a decrease in the battery's range, it can be used to help quantify the suspected performance decline.




Option 2: Purchase a like-for-like replacement


If your battery is out of warranty, the next logical step is to purchase a like-for-like replacement. Even for electric bicycles that are a decade or more old, it is often still possible, particularly for models equipped with high-quality motor systems from brands like Bosch, Shimano, Yamaha, and Brose.



The industry advice is to only replace with a battery from the same manufacturer and with identical specifications. There are good reasons for this – the battery, controller, and motor are all designed to work together safely, and using a "non-original" replacement pack may introduce uncontrolled risks.



That being said, you can choose to upgrade to a larger capacity battery offered by the same manufacturer. Some Bosch and Shimano batteries of different capacities are explicitly interchangeable.



If your battery is out of warranty, the next logical step is to purchase a like-for-like replacement. Unfortunately, this is not always an option. Electric bicycle technology is constantly evolving, and older batteries may no longer be in production.






Option 3: Refurbishment


If your product is out of warranty and direct replacement is not possible, the next obvious step is repair or "rejuvenation" (replacing the internal cells of the battery with new ones). Rejuvenation undoubtedly carries risks, especially if you use a non-professional company, so choosing the right place for rejuvenation is crucial.



As we reported in February, the industry view expressed by CONEBI is that only original OEM-certified batteries should be used as replacements for electric bicycles. This is certainly the ideal choice for obtaining high-quality replacements, but it is often simply not possible for older electric bicycles.



Hannes De Jong runs Heskon, a leading electric bicycle recycling and repair service in Europe. He acknowledges the concerns raised by CONEBI but believes that with the maturity of the industry, refurbishment may be the way forward.



"While there are safety risks with using a small, inexperienced company for recycling or repair, I believe certification can address many of the concerns raised by CONEBI," he told us. "Most importantly, the new EU legislation that is currently being formulated should make repair/reuse the first choice."



Similarly, ChamRider notes that there are currently no clear rules specifying that repair and refurbishment services work with original manufacturers or even require them to recertify the batteries. This is precisely why De Jong wants to introduce certification standards so that professional companies like Heskon can provide reliable and sustainable services while strengthening legal standards.



Mid-drive motors of high quality have been around for decades, and there are now a large number of electric bicycles no longer in production with proprietary electronics in their original batteries. Of course, in many cases, the original suppliers and/or manufacturers of the electric bicycles cannot be traced or have ceased operations. This is where things get tricky.

Whether it is repairing completely failed batteries or, more commonly, performing a full recharge due to the decreased capacity from years of use, there are companies in the industry with a long history and good reputation. We interviewed two of them to delve into what can be done and what cannot be done.



Conclusion


Although electric bicycle battery refurbishment is a hot topic in the industry and not without risks, it has significant sustainable potential and should be organized and certified to provide cost-effective and safe options for old electric bicycles, especially when original battery replacements from the manufacturer are not available.



Recently, a reader contacted us and, after having problematic batteries refurbished at Ebike Batteries in London, they are back on the road. Another option implied by advice given by original manufacturers to customers is that the bike cannot be used as an electric bicycle anymore. This essentially means discarding a perfectly functional electric bicycle.



As a final note on battery safety, it is worth emphasizing that even with high-quality batteries, other equally important measures need to be taken.



Unsupervised charging should be avoided, especially overnight. Similarly, whenever possible, you should always use the charger provided by the original manufacturer.



The one that comes with the battery should be well-matched and not cause overcharging. Using a different charger may result in malfunctions during the charging process.



Using replacement batteries from non-original manufacturers (whether or not involving dealers) may also void the warranty for your electric bicycle or kit. Consult your electric bicycle or kit company to understand their policies regarding the use of aftermarket replacement batteries.



It may not be crucial if it allows you to continue using an old electric bicycle that would otherwise be scrapped, but as you can see from the information above, you may have other options to consider before going down that path.
