What was recalled
The U.S. Consumer Product Safety Commission (CPSC) has issued a significant recall involving specific models of electric bicycles manufactured and sold under the brand name FENGQS. This action targets a distinct subset of consumer e-bikes that were identified as posing serious safety risks due to defects in their power source components. The primary product affected by this recall is the FENGQS F7 Pro electric bike. It is important for consumers to understand that this recall does not apply to every FENGQS bike ever made, nor does it cover all models currently on the market. It is strictly limited to the F7 Pro model equipped with batteries manufactured on a specific date: April 21, 2024.
If you own an electric bike, verifying whether your unit falls within this recall requires careful attention to physical markings and labels. The recalled e-bikes were distinguished by their blue color finish. To confirm if your bike is part of this specific safety notice, look for the brand name "FENGQS" printed clearly on the downtube of the bicycle frame. Additionally, near the rear wheel on the chain stay, you should find the model number "F7 Pro" printed. These visual identifiers are crucial first steps in determining if your vehicle is subject to this order.
Beyond the frame markings, the most critical verification point lies with the battery itself. The recall specifically targets units where the battery’s production date is listed as April 21, 2024. This date, along with the battery’s capacity of 21.5Ah, should be printed on a label located on the front of the battery unit. If your battery does not display this exact manufacturing date, it is not part of the recalled group according to the current CPSC report.
These recalled FENGQS F7 Pro electric bikes were sold through Amazon. While the recall facts provided do not specify the exact number of units affected or the precise start and end dates of sales on the platform, they confirm that Amazon was the primary point of sale for these defective items. If you purchased a blue FENGQS F7 Pro e-bike from Amazon and it bears the April 21, 2024 battery date, your unit is included in this recall. The CPSC initiated this recall on July 24, 2025, to address the growing number of incidents related to these specific batteries.
Understanding exactly what has been recalled helps prevent unnecessary panic while ensuring that those with the dangerous products take immediate action. By focusing on the specific brand, model, color, and battery manufacturing date, consumers can accurately determine their risk status without guessing or relying on vague descriptions.
The hazard, explained
At the heart of this recall is a specific flaw within the lithium-ion battery packs installed in these FENGQS electric bikes. To understand why this is dangerous, it helps to look at what happens inside that battery during normal operation and how things can go wrong. Lithium-ion batteries are designed to store energy by moving lithium ions between two electrodes. Under ideal conditions, this process is stable and efficient. However, in the recalled units, evidence suggests that the cells can overheat beyond their safe operating limits. When a lithium-ion battery gets too hot, it can enter a state known as "thermal runaway." This is not just a minor malfunction; it is a self-sustaining chain reaction where heat generates more heat.
Once thermal runaway begins, the internal chemicals of the battery break down rapidly. This breakdown releases flammable gases and increases internal pressure until the battery casing can no longer contain it. The result is often an intense, rapid ignition. In the case of these e-bikes, this means the battery does not simply stop working; it catches fire. Because e-bike batteries are typically large and hold a significant amount of energy, the resulting fire can be sudden and difficult to extinguish with standard household methods. The heat generated is intense enough to cause severe burns to anyone nearby, whether they are riding the bike, charging it in their garage, or simply walking past it.
The severity of this hazard is underscored by the reports FENGQS has already received. There have been 13 confirmed incidents where these e-bikes ignited. While not every report resulted in a large-scale blaze, two of these incidents led to property damage estimated at $4,000 each. This indicates that the fire potential is real and capable of damaging homes or other structures if the bike is charging indoors or near combustible materials. The risk extends beyond property loss; the primary concern is personal safety. Burns from lithium-ion battery fires are often deep and painful, and the smoke produced can be toxic. For riders, a fire while in motion could lead to loss of control and serious physical injury. For owners charging their bikes at home, the unpredictability of thermal runaway makes it critical to act immediately if you suspect your unit is part of this recall.
It is important to note that these failures are not due to user error or normal wear and tear in most cases. They stem from a manufacturing defect that allows the battery to reach unsafe temperatures under conditions that should be considered standard. This is why the CPSC has deemed it necessary to issue a full recall rather than a simple software update or minor repair. The physical integrity of the battery cell itself is compromised, meaning no amount of careful usage can guarantee safety once the defect is present.
Who is most at risk
The primary group at immediate risk consists of individuals who purchased the FENGQS F7 Pro electric bike in blue and have not yet addressed the battery issue. Because these specific units were sold through Amazon, this recall affects a widespread consumer base that may not be aware of the underlying danger until they see the official notice. The vulnerability here is not just about ownership, but about the specific configuration of the battery pack. If you bought this model with a battery manufactured on April 21, 2024, your device contains the exact component that has been linked to overheating and ignition. The fact that "FENGQS" is printed on the downtube and the model number "F7 Pro" appears near the rear wheel makes identification straightforward, but it also means that anyone using this blue e-bike is potentially holding a fire hazard in their garage or home.
While any user of the recalled bike faces the threat of serious injury or death from fire and burns, certain demographics are particularly vulnerable to the consequences of such an incident. Elderly individuals and those with mobility challenges often rely on electric bikes for independence and transportation. For these users, an e-bike is not merely a recreational toy but a critical tool for daily life. A sudden battery failure while riding could lead to a fall, resulting in fractures or head trauma before the fire even becomes a factor. Furthermore, if the bike ignites while charging at home, elderly residents may have slower reaction times or physical limitations that make escaping a rapidly spreading fire more difficult.
Children and teenagers who use these bikes for school commutes or leisure are also at significant risk. Lithium-ion battery fires can escalate with terrifying speed, often producing toxic fumes and intense heat in seconds. Younger riders may not recognize the early warning signs of battery failure, such as unusual heating or swelling, until it is too late. Additionally, if a child’s bike is charged indoors or in an attached garage, the risk extends to their entire family. The reported incidents include fires that caused property damage, highlighting that the danger does not stay contained within the bike itself. A burning battery can ignite nearby furniture, curtains, or structural elements of a home, putting everyone in the household at risk, especially those sleeping nearby.
We must also consider individuals living in multi-unit housing, such as apartments or condominiums. In these shared environments, a single e-bike fire can threaten neighbors and compromise building safety systems. The intense heat and smoke from a lithium-ion battery fire are difficult to extinguish with standard household fire extinguishers, requiring professional firefighting resources. Therefore, the risk is not isolated to the owner; it extends to anyone who shares walls, floors, or ventilation systems with the person using the recalled e-bike. This makes prompt disposal and refund essential not just for personal safety, but for community well-being.
Finally, people who are financially constrained may hesitate to stop using the bike due to the cost of replacement or transportation. However, this recall offers a full refund, which should alleviate some of that pressure. Ignoring the risk because of inconvenience is dangerous, as the potential costs—medical bills, property loss, and emotional trauma—far outweigh the effort of contacting FENGQS. The urgency is real, and the most vulnerable among us are those who might delay action due to confusion or fear of the process. Please do not wait; your safety and the safety of those around you depend on immediate steps.
How to tell if you have the recalled item
Because electric bikes can look quite similar on the surface, relying solely on the brand name isn't enough to ensure your safety. You need to check specific physical details printed directly on the bike itself and on the battery pack. The recall targets a very specific batch of FENGQS F7 Pro electric bikes. If you purchased an e-bike from Amazon that is blue in color, this is your first strong indicator that you might be affected. However, color alone is not enough to confirm the recall, as manufacturers sometimes change paint schemes over time.
To definitively identify your bike, you must look for two distinct pieces of text printed on the frame. First, check the downtube—the large tube running from the handlebars down to the pedals. The brand name "FENGQS" should be clearly printed there. Second, move to the rear of the bike and look at the chain stay, which is the horizontal tube connecting the rear wheel hub to the center of the bike where the pedals attach. Near the rear wheel on this chain stay, you should see the model number "F7 Pro" printed. If your bike matches these descriptions, it is likely the recalled unit.
The most critical step is verifying the battery's production date, as this recall only applies to batteries manufactured on April 21, 2024. You need to locate the label on the front face of the battery pack. This label contains two key pieces of information: the battery capacity, which should read "21.5Ah," and the production date. Look closely for the date code "2024/4/21." If your battery has this specific date, it is part of the recall and poses a fire hazard. If the date is different, or if you cannot find these specific markings, your bike may not be included in this particular safety notice.
If you are unsure or cannot locate these labels, do not guess. The safest approach is to stop using the bike immediately and contact FENGQS directly for confirmation. You can reach them at 607-307-2127 between 9 a.m. and 5 p.m. ET, Monday through Friday, or by emailing recall@fengqs.work. They can help you verify your specific unit's status based on additional details you might have, such as purchase records or serial numbers not listed in the general description.
What to do — step by step
If you own a blue FENGQS F7 Pro electric bike, your first and most critical action is to stop using the bike immediately. This is not a suggestion; it is a necessary safety measure. The recall stems from a specific defect in the lithium-ion battery that can cause it to overheat and ignite, creating serious fire and burn hazards. Because these batteries have already been linked to 13 reports of ignition—including two incidents that caused $4,000 in property damage—continued use poses a significant risk to you, your home, and your family. Please do not charge the bike or attempt to ride it again until you have completed the steps below. Next, you need to prepare the battery for its safe return by marking it clearly so that FENGQS can identify it as part of this specific recall program. Take a permanent marker and write three pieces of information on the battery’s label: your name, the word "recalled," and today’s current date. Make sure this writing is placed next to the existing production date printed on the front of the battery. This step is crucial because it allows FENGQS to verify that your unit is indeed one of the affected models manufactured on April 21, 2024. Without this clear marking, they may not be able to process your refund correctly. Once you have marked the battery, take a clear, well-lit photograph that shows both the newly written information and the original production date label. You will need to submit this photo as proof of compliance. Send the image to their dedicated recall email address at recall@fengqs.work. In your email, simply state that you are submitting the required photo for the recalled F7 Pro e-bike. FENGQS is offering a full refund for these units, so once they receive and verify your photo, they will process your reimbursement. If you have any questions or need assistance during this process, you can also contact them directly at 607-307-2127 between 9 a.m. and 5 p.m. ET, Monday through Friday, or visit www.fengqs.com/pages/recalls for more details. Finally, you must dispose of the recalled battery properly. Do not throw it in your regular household trash, nor should you place it in curbside recycling bins or the used battery drop-off boxes often found at retail stores. Standard disposal methods are unsafe for recalled lithium-ion batteries due to their heightened fire risk. Instead, contact your local municipal household hazardous waste (HHW) collection center before bringing the item there. Call ahead to confirm they accept recalled lithium-ion batteries, as policies vary by location. If your HHW center does not accept them, reach out to your municipality for specific guidance on safe disposal. This careful handling protects sanitation workers and the environment from potential fire hazards associated with improper battery disposal.Your refund, repair, or replacement options
If you own one of the recalled FENGQS F7 Pro electric bikes, your primary remedy is a full refund. The Consumer Product Safety Commission (CPSC) has confirmed that FENGQS is not offering repairs or replacements for this specific model due to the inherent design flaw in the lithium-ion batteries. Instead, the company is asking consumers to return their units by stopping use immediately and initiating a refund process directly with the manufacturer. This approach prioritizes your safety over product retention, as keeping the bike, even with a potential fix, would still leave you with a device capable of overheating and igniting.
To receive your full refund, you must follow a specific verification procedure designed to ensure that the recalled batteries are safely removed from circulation. You cannot simply send the bike back or request money without first proving that the battery is being disposed of correctly. The process requires you to take a permanent marker and write your name, the word "recalled," and today’s date next to the battery’s production date on the label. This creates a clear, unalterable record linking the specific unit to this recall event.
Once you have marked the battery, you must take a clear photograph that shows this written information alongside the existing production date. This photo serves as your proof of compliance and is the key to unlocking your refund. You are required to submit this image via email to recall@fengqs.work. It is crucial that the image is legible and clearly displays both your added text and the original manufacturing details. Do not attempt to mail physical documents or the battery itself without first confirming the specific disposal instructions with FENGQS, as improper mailing of lithium-ion batteries can pose significant fire risks to postal workers and facilities.
FENGQS has established several ways for you to reach out if you have questions about this process. You can contact them by phone at 607-307-2127 between 9 a.m. and 5 p.m. ET, Monday through Friday. Alternatively, you may visit their website at www.fengqs.com/pages/recalls or go to the main site at www.fengqs.com and click on "Recalls" in the top navigation bar for additional support. While the remedy is strictly a refund, the company emphasizes that you must also confirm that you are disposing of the battery in accordance with applicable laws and regulations. This means you should not throw the bike or battery in the trash or standard curbside recycling. Instead, contact your local municipal household hazardous waste (HHW) collection center to see if they accept recalled lithium-ion batteries, ensuring you call ahead to confirm their current policies before transporting the device.
What can happen if you ignore it
It is completely understandable to feel hesitant about stopping the use of a major purchase like an electric bike, especially when the issue seems internal or hidden within the battery pack. You might think that as long as the bike looks fine on the outside and charges normally today, it will be safe tomorrow. However, ignoring this recall carries serious, immediate risks that go far beyond simple mechanical failure. The core danger lies in the nature of the lithium-ion batteries involved. These energy-dense cells can experience thermal runaway—a rapid, uncontrollable rise in temperature that leads to ignition. This is not a gradual process; it can happen suddenly and without warning, even if the bike has been sitting idle or was only recently used.
The consequences of continuing to use these recalled FENGQS e-bikes are not theoretical. According to the Consumer Product Safety Commission (CPSC), FENGQS has already received 13 separate reports of these specific e-bikes igniting. While we do not have detailed public accounts of every single event, the data indicates that two of these incidents resulted in actual fires that caused property damage totaling $4,000. This means that for those owners, the fire spread beyond just the battery, damaging homes, garages, or other belongings. The risk is not limited to property loss; the intense heat and flames associated with lithium-ion battery fires pose a direct threat of serious injury or death to consumers nearby. Inhalation of toxic fumes, severe burns, and smoke inhalation are real dangers that can occur in the seconds it takes for emergency services to arrive.
When you ignore a recall for a product with a known fire hazard, you are essentially gambling with your safety and the safety of your household. Lithium-ion fires are notoriously difficult to extinguish because they generate their own oxygen and can reignite hours or even days after the initial flame is put out. If you continue to charge or ride these bikes, you are allowing a potential ignition source to remain in your living space, garage, or workplace. The probability of an incident may feel low in the moment, but the severity of the outcome when it does occur is catastrophic. There is no "safe enough" level of risk when dealing with uncontrolled battery fires. By acting now, you are removing a volatile hazard from your environment; by ignoring it, you leave that hazard active and unpredictable.
- Rapid Escalation: Battery fires can escalate from a small spark to a fully engulfed blaze in seconds, leaving little time for escape.
- Toxic Exposure: Burning lithium-ion batteries release hazardous chemicals that can cause respiratory distress and long-term health issues.
- Financial Liability: Beyond the loss of the bike, you could be responsible for significant property damage to your home or neighbors' properties, as seen in the reported $4,000 in damages.
Please do not wait for a fire to start. The fact that these incidents have already been reported confirms that the defect is real and active. Your safety is worth more than the inconvenience of packing up a battery or waiting for a refund. Take the time today to mark, photograph, and dispose of your unit properly through the official channels.
Staying safe: broader tips
While this specific recall addresses a critical defect in a particular batch of lithium-ion batteries, the underlying lesson applies to anyone who owns modern electric mobility devices. Lithium-ion technology has revolutionized how we power our lives, offering incredible energy density and convenience. However, these batteries are sensitive chemical systems that require respect and proper handling to remain safe. The most fundamental rule is to never use a charger or battery that does not match the exact specifications of your device. Using third-party chargers, even if they physically fit, can bypass built-in safety circuits and lead to overheating. Always stick to the original manufacturer’s charging equipment, and ensure that any replacement parts are certified by the bike’s maker.
Environmental conditions play a huge role in battery health. Never charge your e-bike indoors, especially overnight or while you are asleep. If a thermal runaway event occurs—a sudden, uncontrollable rise in temperature—it is far safer for it to happen in a detached garage, shed, or outdoor area away from your home and family. Additionally, avoid leaving your bike plugged in once the battery reaches 100%. Most modern chargers have cut-off features, but prolonged connection can generate unnecessary heat over time. If you notice your battery casing becoming hot to the touch during use or charging, unplug it immediately and let it cool down in a safe, open space.
Regular physical inspections are your first line of defense. Look for any signs of swelling, leaking, or discoloration on the battery pack. A swollen battery is a clear sign of internal failure and should be treated as highly dangerous; do not attempt to puncture or repair it yourself. Store your e-bike in a dry, cool place, as extreme heat can degrade battery cells faster, and moisture can corrode electrical contacts. Keep an eye on the connection points between the battery and the frame, ensuring they are clean and free of debris.
Finally, stay informed about safety recalls beyond just this incident. The Consumer Product Safety Commission (CPSC) maintains a public database of recalls that is updated daily. Signing up for email alerts from CPSC or checking their website periodically can help you catch issues with older products before they become dangerous. For your peace of mind, consider purchasing a basic fire extinguisher rated for electrical fires (Class C) and keep it accessible in your garage or storage area. Being prepared with the right tools and knowledge turns a potential emergency into a manageable situation.
