What was recalled
In early February 2019, the U.S. Consumer Product Safety Commission (CPSC) announced a significant safety recall involving specific internal gear hubs manufactured by SRAM. This action was taken to address serious mechanical failures that could leave riders without adequate braking power. The recall specifically targets SRAM® i-Motion 3 three-speed internal gear hubs that are equipped with a coaster brake mechanism. It is important to understand that this issue is not limited to bicycles sold as complete units; the recalled components were also distributed as aftermarket parts, meaning they may have been installed on various other bicycle models by mechanics or individual owners seeking upgrades.
The primary vehicles affected in this recall are certain Electra® brand bicycles. If you own an Electra bike from that era, you should check your model name carefully. The recall includes the following specific Electra models: the Electra Cruiser Custom 3i, the Electra Coaster 3i, the Electra Hawaii 3i, the Electra Hawaii 3i 24, and the Electra Straight 8. These bicycles were originally sold with the defective SRAM i-Motion 3 hubs installed at the factory. However, because these hubs are also available as standalone replacement parts, they may be found on other brands of bicycles that have undergone maintenance or customization.
To identify if your bicycle is part of this recall, you need to look closely at the rear wheel hub. The recalled units will clearly have "SRAM i-Motion 3" printed on the hub shell. Additionally, you will see a brake arm extending from the axle of the hub. This physical configuration is distinct and should be easy to verify. The recall does not cover all SRAM products, only this specific three-speed internal gear hub model with the coaster brake feature.
The scope of this recall is defined by the sales channels and timeframes during which these defective hubs were distributed. While the CPSC notice from February 21, 2019, does not provide an exact count of the total number of units affected, it emphasizes that these parts were sold both new on complete bicycles and as aftermarket components. This means that even if your bicycle is not one of the specific Electra models listed above, it could still be at risk if a SRAM i-Motion 3 hub with a coaster brake was installed during service or customization. The lack of redundant braking systems on these particular setups amplifies the danger, as the failure of this single hub’s brake leaves the rider with no other means to stop effectively.
Understanding the precise nature of the recalled product is the first step in ensuring your safety. By identifying the brand, model, and physical characteristics described here, you can determine whether your bicycle falls under this specific recall notice. If you are unsure, it is always safer to contact SRAM directly for verification rather than guessing based on incomplete information.
The hazard, explained
At the heart of this recall is a failure within the braking mechanism of SRAM i-Motion 3 three-speed internal gear hubs. To understand why this is dangerous, it helps to look at how these specific components are designed and where that design falls short in critical situations. The recalled hubs are installed on certain Electra bicycles that rely entirely on a coaster brake for stopping. A coaster brake is integrated into the rear wheel hub; you stop by pedaling backward, which engages the brakes inside the hub. In many bicycle designs, especially those built for comfort or cruising like the Electra models listed here, there is often no secondary braking system, such as hand-operated rim or disc brakes on the front fork. This means your entire ability to slow down and stop depends 100% on that single rear hub mechanism working perfectly every time.
The specific physical failure reported involves the brake arm extending from the axle of the hub. In a properly functioning i-Motion 3 hub, this arm connects to the internal braking components that engage when you pedal backward. However, in the recalled units, this brake arm or its connection point can fail. When this mechanical failure occurs, the link between your pedaling action and the actual braking force is broken. You might pedal backward with full effort, expecting the bike to slow down, but the internal mechanism fails to engage or loses tension entirely. Because there are no redundant brakes on these specific bicycle models, you are left with no way to stop the bicycle mechanically. This is not a minor glitch; it is a total loss of braking capability.
The consequence of this failure is immediate and severe for the rider. Without a working brake, the bicycle continues to move under its own momentum regardless of what the rider does with their feet. If this happens while riding in traffic, on a sidewalk, or near obstacles, the rider cannot slow down to avoid collisions. The CPSC notes that SRAM has already received five reports of this brake failure. In one documented case, this mechanical failure resulted in a minor injury to a rider. While we are fortunate that the reported injuries have been minor so far, the physics of a sudden loss of control on a moving bicycle can lead to much more serious harm. Riders can fall off the bike, be struck by other vehicles or pedestrians, or crash into stationary objects. The risk is particularly high for casual riders who may not anticipate such a sudden mechanical failure, as they are relying on the brake as their primary and only safety tool.
It is important to recognize that this hazard is not just about the hub itself failing in isolation, but about the system design. By selling these hubs on bicycles with no redundant braking system, the manufacturer created a single point of failure. In engineering terms, redundancy is a key safety principle: if one system fails, another should take over. Here, there is no backup. When the brake arm fails, the rider has no alternative means to apply friction to the wheels. This makes the potential for a crash significantly more likely than in bicycles equipped with front and rear hand brakes, where a failure in one can be compensated for by the other. Understanding this lack of redundancy helps explain why the CPSC has deemed this hazard serious enough to warrant an immediate recall and partial refund.
Who is most at risk
The primary group at immediate risk consists of owners and riders of specific Electra® bicycle models that were equipped with the recalled SRAM® i-Motion 3 internal gear hubs. This includes the Electra Cruiser Custom 3i, Electra Coaster 3i, Electra Hawaii 3i, Electra Hawaii 3i 24, and the Electra Straight 8. It is important to note that these bicycles were sold with a critical safety gap: they lacked a redundant braking system. While most modern bicycles come with at least two independent braking mechanisms (such as hand brakes on both wheels) to ensure stopping power even if one fails, these specific Electra models relied solely on the coaster brake integrated into the rear hub. If that single point of failure—the SRAM i-Motion 3 hub—malfunctions, the rider is left with zero means to slow down or stop the bicycle effectively.
Riders who purchased these hubs as aftermarket parts for other bicycles are also at significant risk. Anyone who has upgraded their existing bike with a SRAM i-Motion 3 hub that features "SRAM i-Motion 3" printed on the shell and a brake arm extending from the axle is using a product with a known defect. Because these were sold as replacement components, they may be installed on older frames or non-Electra brands, meaning the risk extends beyond just one manufacturer’s lineup to any bicycle owner who has performed this specific upgrade.
In terms of physical vulnerability, individuals with less stability, strength, or reaction time face the most severe consequences from a brake failure. Elderly riders, who often use cruiser-style bikes like the Electra models for leisure and low-speed commuting, may have reduced bone density and slower reflexes. A sudden loss of braking power while riding, even at moderate speeds, can lead to falls that result in fractures or serious head injuries. Similarly, parents allowing young children to ride these bicycles are exposing them to heightened danger. Children often lack the physical strength to pump brakes vigorously and may not understand how to react to a mechanical failure until it is too late. The fact that SRAM has already received five reports of brake failure resulting in one minor injury confirms that this is not just a theoretical risk but an active hazard affecting real-world users.
Furthermore, the nature of coaster brakes requires the rider to pedal backward to engage braking. If the internal mechanism fails due to the defect described, the connection between the rider’s effort and the bike’s stopping power is severed completely. This can be particularly disorienting and dangerous for casual riders or those unfamiliar with mechanical bicycle issues, who might continue pedaling in panic while the bike continues to roll forward uncontrollably. Therefore, anyone using these bicycles for daily transport, recreational cruising, or family outings is potentially at risk until the remedy is applied.
How to tell if you have the recalled item
Identifying whether your bicycle contains the specific gear hubs involved in this recall requires a careful, hands-on inspection of the rear wheel assembly. Because SRAM i-Motion 3 three-speed internal gear hubs with coaster brakes were sold both as original equipment on certain Electra® bicycles and as aftermarket parts for other brands, you cannot rely solely on the bicycle’s brand name to determine if your bike is affected. While the recall specifically lists several Electra models—including the Cruiser Custom 3i, Coaster 3i, Hawaii 3i, Hawaii 3i 24, and Straight 8—as well as aftermarket installations, the definitive proof lies in the hardware itself. If you own an Electra bicycle from this list, it is highly likely to be affected, but you must verify the hub details to be certain.
To confirm your status, locate the rear wheel of your bicycle and look at the central hub shell. You need to find specific printed markings that identify the manufacturer and model. Look closely for the text "SRAM i-Motion 3" clearly printed on the side of the hub shell. This branding is the primary identifier for the recalled component. Additionally, examine the axle area extending from the hub. The recalled units feature a distinct brake arm that extends outward from the axle. If you see this specific combination of printed text and the physical brake arm structure, your bicycle contains the recalled gear hub.
If your bicycle is not one of the listed Electra models, or if it is a custom build with mixed brands, you must inspect the rear hub directly regardless of what brand is on the frame. The recall covers any SRAM i-Motion 3 three-speed internal gear hub with a coaster brake, whether it was installed at the factory or added later by a shop owner. There are no color or size variations that exempt a unit; the safety hazard is inherent to the mechanical design of the brake system within the hub itself. Therefore, visual confirmation of the "SRAM i-Motion 3" label and the extending brake arm is the only reliable method to determine if your specific bike is part of this safety notice. If you cannot find these markings or are unsure after a close inspection, do not guess. Contact SRAM directly using the phone number or website provided in the remedy section for expert verification.
What to do — step by step
If you own a bicycle equipped with the affected SRAM i-Motion 3 internal gear hubs, your immediate priority is safety, not convenience. The recall notice issued by the Consumer Product Safety Commission (CPSC) on February 21, 2019, makes one thing abundantly clear: you must stop using these bicycles right away. This is not a suggestion to wait until the next scheduled maintenance appointment; it is an urgent directive. The hazard involves the failure of the coaster brakes within the gear hubs, which can lead to sudden loss of braking power while riding. If you continue to ride, you are risking a crash and potential injury to yourself or others. Please remove the bicycle from service immediately. Do not attempt to fix the brake mechanism yourself, as these are complex internal components that require professional handling and specific manufacturer protocols.
Once the bicycle is safely parked and no longer being ridden, your next step is to initiate contact with SRAM to arrange for your remedy. You have two primary ways to reach them. The most direct method is to call their dedicated consumer support line at 800-346-2928. When you call, please be aware of their specific operating hours to ensure you can speak with a representative. They are available from 10 a.m. to 7 p.m. Eastern Time on Monday through Thursday, and their Friday hours are slightly shorter, running from 10 a.m. to 6 p.m. Eastern Time. Having your bicycle’s model information ready when you call will help speed up the process, as they will need to verify that your specific unit is part of this recall batch.
If you prefer digital communication or find it difficult to navigate phone lines during peak hours, you can also access the recall notice online. Visit either www.sram.com or www.zipp.com. On these websites, look for the “Recall Notice” section. This online portal will provide you with detailed instructions on how to proceed. Whether you are calling or visiting the website, the core action remains the same: you must contact SRAM directly to receive instructions on how to get a partial refund. The remedy for this specific recall is not a free repair or a replacement hub; it is a financial reimbursement. Therefore, following their instructions precisely is essential to ensure you receive the compensation you are entitled to.
As you go through these steps, keep your bicycle’s documentation handy. Although the recall does not explicitly state that you must mail in the old hub, having proof of purchase or the serial number of your Electra bicycle (such as the Cruiser Custom 3i, Coaster 3i, Hawaii 3i, Hawaii 3i 24, or Straight 8) will be incredibly helpful. If the bicycle was purchased as an aftermarket part rather than a complete bike, having the original receipt from the local bike shop where you bought the SRAM hub will also be necessary. By following these steps calmly and methodically, you ensure your safety is restored and that you handle the administrative side of the recall efficiently.
Your refund, repair, or replacement options
If you have determined that your bicycle is part of this recall, the first and most important step is to stop riding it immediately. You do not need to wait for a kit or a new part to arrive before taking action. The remedy provided by SRAM is straightforward and consumer-friendly: they are offering a partial refund rather than a free repair or replacement hub. This approach recognizes that the issue lies with the integrated braking system within the gear hub, which may require more than a simple swap-out depending on the bicycle’s frame design. By issuing a partial refund, SRAM acknowledges the inconvenience and allows you to decide how best to proceed with your specific bike, whether that means using the funds toward professional repairs elsewhere or toward purchasing a different model entirely.
To initiate this process, you will need to contact SRAM directly. They have established specific channels for consumers to receive instructions on how to claim this partial refund. You can reach their support team by phone at 800-346-2928. It is helpful to keep in mind their operating hours when planning your call: they are available from 10 a.m. to 7 p.m. Eastern Time on Mondays through Thursdays, and from 10 a.m. to 6 p.m. Eastern Time on Fridays. Having your bicycle’s model number and the serial number of the hub ready before you call can help speed up the process, although the recall notice emphasizes contacting them for instructions rather than requiring pre-submitted data.
If you prefer digital communication or wish to review the full details of the recall terms before calling, SRAM has made information available online. You can visit either www.sram.com or www.zipp.com. On these sites, look for the “Recall Notice” section to find the official documentation and the specific steps required to qualify for the refund. The instructions will likely require you to provide proof of purchase or details about where and when the bicycle was acquired, as well as confirmation that the bicycle contains one of the affected SRAM i-Motion 3 hubs.
It is important to note that this remedy applies specifically to the recalled hubs sold on Electra models (Cruiser Custom 3i, Coaster 3i, Hawaii 3i, Hawaii 3i 24, and Straight 8) as well as those sold as aftermarket parts. If you purchased your bicycle second-hand or cannot find the original receipt, do not panic; SRAM’s online resources should guide you on alternative verification methods. The goal of this remedy is to ensure you are compensated for the safety risk without placing the burden of complex mechanical repairs entirely on you. Once you have followed their instructions and received your refund, you can make an informed decision about whether to repair the bike with a non-recalled component or replace the bicycle altogether.
What can happen if you ignore it
It is completely understandable to want to continue using your bicycle as normal. Perhaps you have already invested time in getting comfortable with the ride, or maybe the inconvenience of contacting customer support feels like a burden you would rather avoid until later. However, ignoring this specific recall carries significant and immediate risks that go far beyond mere mechanical annoyance. The core issue here is not just that a part might eventually wear out; it is that the braking mechanism within the SRAM i-Motion 3 gear hubs can fail without warning. When you choose to keep riding with these recalled hubs, you are essentially betting your physical safety on the hope that the brake will hold up under pressure.
The reality of this hazard is rooted in physics and basic vehicle dynamics. These internal gear hubs combine shifting gears with braking functionality. When the brake fails, you lose a critical layer of control over your speed and stopping distance. In urban environments or on busy bike paths, the ability to stop quickly and predictably is non-negotiable. If the coaster brake engages inconsistently or stops working entirely while you are descending a hill or approaching an intersection, the sudden loss of braking power can be terrifying and dangerous. You may find yourself unable to slow down sufficiently to avoid a collision with a pedestrian, another cyclist, or a stationary object.
We must also look at the data provided by SRAM to understand the severity of this risk. The company has already received five distinct reports of brake failure associated with these specific hubs. While five incidents may seem like a small number in the grand scheme of things, each one represents a moment where a rider’s safety was compromised. More concerning is the fact that these failures have already resulted in at least one minor injury. This confirms that the hazard is not theoretical; it is real and has already caused physical harm to riders who were using the product as intended. The potential for more severe injuries, such as fractures, road rash, or head trauma from a fall, increases dramatically with every mile you log on these affected bicycles.
Furthermore, the nature of the defect makes it particularly insidious. Because the brake is integrated into the hub, you might not notice any warning signs before a total failure occurs. There may be no squealing, grinding, or visible damage to alert you that the system is failing. This lack of forewarning means that when the brake does fail, it likely will happen during a critical moment when you need it most. Continuing to ride with this defect transforms your bicycle from a reliable mode of transportation into an unpredictable liability. The peace of mind you think you are saving by delaying action is illusory; in truth, you are trading your safety for temporary convenience, putting yourself and those around you at unnecessary risk.
Finally, consider the broader implications of ignoring the recall. Beyond the immediate physical danger, there is the emotional toll of knowing you were aware of a defect but chose to proceed anyway. If an accident were to occur, it would not only be traumatic but could also complicate any potential legal or insurance matters. The remedy offered by SRAM is straightforward and designed to remove this risk entirely. By waiting, you are not just delaying a refund; you are prolonging your exposure to a known danger that has already been documented to cause injury. The smartest, safest choice is always to prioritize your well-being over the inconvenience of a phone call or an online form.
Staying safe: broader tips
While this specific recall addresses a mechanical failure in SRAM gear hubs, the underlying principle applies to all complex consumer products: safety is an ongoing practice, not a one-time event. When you own items that involve moving parts, electricity, or structural integrity—such as bicycles, power tools, or even children’s toys—you become the first line of defense against potential hazards. The most effective way to stay safe is to cultivate a habit of proactive maintenance and regular inspection. For cyclists, this means regularly checking brake pads for wear, ensuring tires are inflated to the manufacturer’s recommended pressure, and verifying that all bolts and fasteners are tight. A loose bolt might seem minor today, but over time, vibration and stress can cause it to fail, leading to loss of control. By performing simple visual and physical checks before every ride, you can identify wear patterns or damage early, long before a catastrophic failure occurs.
Beyond regular maintenance, staying informed is equally critical. Manufacturers issue recalls not just because something broke, but because they have identified a potential design flaw that could affect safety under specific conditions. You cannot protect yourself from hazards you do not know about. Therefore, it is wise to register your products with the manufacturer whenever possible. This ensures that if a recall is issued, you are notified directly via email or mail rather than having to hunt for the information. Additionally, subscribe to official safety alerts from relevant government agencies, such as the Consumer Product Safety Commission (CPSC) in the United States. These agencies publish weekly updates on recalled products, ranging from cribs and car seats to lawn mowers and electronics. Setting aside ten minutes a month to browse these lists can help you identify if any of your household items are part of an active recall.
Finally, always read the manual. It may feel like extra work, but the user guide contains vital safety warnings and operating limits that are not obvious from the product’s appearance. Manufacturers test their products under specific conditions, and exceeding those limits can void warranties and compromise safety. For example, a bicycle rated for a certain weight limit may fail if overloaded, just as an electrical appliance may overheat if used continuously beyond its rating. By respecting these guidelines and treating your purchases with respect rather than taking them for granted, you significantly reduce the risk of injury. Safety is built on awareness, maintenance, and the willingness to act when something feels or looks wrong.
