Super73 Recalls Z Miami SE and Z Adventure Core Electric Bicycles Due to Crash and Injury Hazards

What was recalled

If you own a Super73 electric bicycle, specifically from the 2024 model year, it is important to pause and verify your specific unit against this recent safety notice. The U.S. Consumer Product Safety Commission (CPSC) has announced a recall affecting two distinct lines of Super73 e-bikes: the Z Miami SE and the Z Adventure Core. This recall was officially initiated on February 20, 2025, because these specific models contain a component that can fail unexpectedly while riding, leading to potential loss of control. To help you identify whether your bike is part of this group, we need to look closely at the model numbers and color options, as Super73 manufactured these bikes in several distinct configurations.

The recall specifically targets the Z Miami SE model, which was sold in three different color schemes. You can identify a Z Miami SE by checking your purchase receipt or the bike’s documentation for one of the following model numbers: 900-00288, 900-00309, or 900-00313. If your bike is a Z Miami SE, it will be one of these three colors: Bandit black with a black seat, Palladium gray with a camel-colored seat, or Astro Orange with a black seat. The second group of affected bicycles is the Z Adventure Core. This model comes in only one color option, known as Sandstorm, which features a distinctive black and brown frame. The model number for the Z Adventure Core is 900-00308.

While the official recall notice provides these precise model numbers and color descriptions to help you identify your bike, it does not explicitly state the total number of units involved in this recall or specify exactly where they were sold (such as specific states or retail partners). However, the manufacturer has confirmed that they are contacting all purchasers directly. If you bought your e-bike from a Super73 retailer or directly from the company during the 2024 model year, it is highly likely your unit is included in this safety campaign. The most reliable way to confirm is to check your original purchase receipt, which should list the model name and color, or to contact Super73 directly using the information provided in the recall notice.

It is worth noting that electric bicycles have become increasingly popular for both commuting and recreation, but they also require rigorous maintenance of their braking systems. The fact that Super73 has issued this recall indicates a proactive approach to safety, aiming to correct a manufacturing flaw before it leads to serious accidents. By identifying your model number now, you can take the necessary steps to ensure your ride remains safe and compliant with current safety standards. Do not rely solely on the color of your bike, as similar models may have different internal components; always verify the model number printed on your documentation or the bike itself.

If you are unsure whether your bike is affected, or if you have lost your receipt, do not guess. The consequences of brake failure on an electric bicycle can be severe, so it is better to be certain. You can reach out to Super73’s customer support team for assistance in verifying your model. They have set up specific channels to handle these inquiries efficiently. Remember, this recall is not about the entire brand of Super73 e-bikes, but only the specific 2024 models listed above. By taking a few minutes to check your model number, you can avoid unnecessary worry and ensure that any necessary repairs are addressed promptly.

The hazard, explained

To understand why this recall is necessary, it helps to look at the specific mechanical failure involved. The issue centers on a small but critical component within the e-bike’s disc brake system: the retaining pin. In a properly functioning caliper assembly, this pin acts as a secure anchor, holding the brake pads in place and ensuring they make consistent, firm contact with the rotor when you squeeze the lever. However, in the recalled Super73 Z Miami SE and Z Adventure Core electric bicycles, this retaining pin can loosen over time. Once it dislodges from its intended position within the caliper assembly, the structural integrity of that side of the braking system is compromised.

When the pin fails, the brake pads are no longer held with the necessary tension or alignment. This leads directly to partial or complete brake failure. In practical terms, this means that when you apply the brakes—whether you are slowing down on a flat street, navigating a steep hill, or coming to a stop at an intersection—the bike may not respond as expected. The distance required to come to a full stop can increase dramatically, or the brakes may feel "spongy" and unresponsive. For electric bicycles, which are significantly heavier than traditional pedal bikes due to their motors and batteries, this loss of stopping power is particularly dangerous.

The risk extends beyond just longer stopping distances. Because the braking force is uneven or absent on one side of the wheel, the bike can pull sharply toward the side with the failing brake. This sudden, unpredictable shift in direction can cause the rider to lose balance, especially at higher speeds or on wet surfaces. The result is a high risk of crashing. While most crashes involving e-bikes are mitigated by the rider’s ability to put a foot down, the added weight and momentum of an electric motor can make it difficult to recover from a sudden loss of control. As noted in the incident reports, this specific mechanical failure has already resulted in injuries, underscoring that this is not merely a performance issue but a serious safety threat.

It is also important to recognize that this failure may not be immediately obvious during casual riding. The pin might loosen gradually, meaning the bike could feel normal for days or weeks before the issue becomes critical. This silent progression is what makes proactive inspection and repair essential. You cannot rely on the brakes feeling "fine" today to guarantee they will work correctly tomorrow if the underlying retaining pin has compromised its position. The remedy provided by Super73 addresses this root cause by replacing the faulty pin, restoring the mechanical connection that keeps your braking system reliable and safe.

Who is most at risk

The primary group at immediate risk consists of the owners and riders of specific Super73 electric bicycles manufactured for the 2024 model year. This includes individuals who purchased the Z Miami SE or the Z Adventure Core models. Because these bikes are often marketed toward commuters, urban riders, and recreational enthusiasts who rely on them for daily transportation or leisure, the potential for harm is widespread among anyone who has recently integrated one of these vehicles into their routine. The risk is not limited to professional cyclists; it extends to casual users who may assume that electric assist features make riding inherently safer or easier to control.

Within this broad group, certain individuals face heightened vulnerability due to the specific nature of the mechanical failure involved. The hazard stems from a retaining pin in the disc brake caliper loosening and dislodging, which leads to sudden brake failure. For elderly riders or those with reduced physical strength, the consequences of losing braking power are particularly severe. Electric bicycles can reach speeds significantly higher than traditional pedal bikes, often exceeding 20 miles per hour. When a rider loses the ability to slow down or stop effectively while traveling at these velocities, the physical force required to regain control increases dramatically. Older adults, who may have slower reflexes or more fragile bones, are at a greater risk of serious injury from falls that might otherwise result in only minor scrapes.

Children and teenagers who ride these models are also in a critical risk category. While they may be physically capable of handling the bike's speed, their judgment regarding distance and reaction time is still developing. A sudden loss of brakes can cause panic, leading to erratic steering or an inability to judge stopping distances correctly. Furthermore, younger riders often use these bikes in mixed environments—sharing paths with pedestrians, cars, and other cyclists. The unpredictability of a brake failure in such crowded spaces increases the likelihood of collisions not just with fixed objects, but with other people, potentially causing harm to bystanders as well.

Additionally, individuals who ride in areas with steep inclines or heavy traffic face compounded risks. The Z Miami SE and Z Adventure Core models are designed for varied terrain. On a downhill slope, brake failure means the bike may accelerate uncontrollably. For riders who are not expert mechanics or who do not regularly inspect their equipment, this silent mechanical failure can occur without warning. The fact that Super73 has already received 21 reports of loose pins indicates that this is not a rare occurrence, making it a pressing concern for every current owner regardless of their riding experience level. The risk is universal to the product line, but the severity of the outcome depends heavily on the rider's age, physical condition, and riding environment.

How to tell if you have the recalled item

Identifying whether your electric bicycle is part of this specific recall requires a careful look at several key details on your purchase receipt and on the physical bike itself. Because Super73 has issued this safety advisory for specific model years and configurations, it is crucial to verify every data point rather than relying on general assumptions about the brand. The recall applies exclusively to model year 2024 units of the Z Miami SE and the Z Adventure Core electric bicycles. If your bike was purchased in a different year, or if it is a different model entirely, such as the standard Z Series without the "Miami" or "Adventure Core" designation, it is not included in this particular safety notice.

First, check your original purchase receipt or order confirmation email. The documentation should clearly list the specific model name and color combination. For the Z Miami SE e-bikes, there are three distinct color variants that fall under this recall: the Bandit black frame with a black seat; the Palladium gray frame with a camel-colored seat; and the Astro Orange frame with a black seat. If you purchased a Z Adventure Core e-bike, it comes in only one colorway: Sandstorm, which features a distinctive black and brown frame. The receipt is your primary source for confirming these details, as the model name and color are explicitly recorded there.

In addition to the visual appearance, you must verify the specific part numbers associated with each model to ensure accuracy. The Z Miami SE e-bikes included in this recall carry the following model numbers: 900-00288, 900-00309, and 900-00313. The Z Adventure Core e-bike is identified by the model number 900-00308. These numbers are critical identifiers. While Super73 and its retailers are contacting all known purchasers directly to notify them of this issue, relying on direct mail or email can be risky if contact information has changed. Therefore, cross-referencing your physical bike’s documentation with these exact numbers is the most reliable method of confirmation.

If you cannot locate your original receipt, look for any labeling on the bicycle frame or the original packaging that might display these part numbers. The recall does not specify serial number ranges for this specific hazard, so the model number and color combination are your definitive guides. Be cautious if you bought a used bike; without access to the original purchase records, it may be difficult to confirm the exact model year and configuration. In such cases, contacting Super73 directly with any available information is strongly recommended to determine if your specific unit is affected.

The manufacturer has established a clear and generous remedy designed to make things right without placing any unexpected costs on you. First and foremost, please remember that you should stop using the bike immediately. Do not ride it to get to the repair location if you can avoid it; use alternative transportation until the issue is resolved. Once you are ready to proceed with the fix, your primary option is to contact Super73 directly to initiate the process. The company will provide you with a free repair kit at no charge. This kit contains the critical component needed to resolve the issue: a new retaining pin for the disc brake calipers.

While the part itself is free, it is important to understand that Super73 strongly recommends having this repair performed by a professional. To support you in getting this done safely and correctly, the company will reimburse you for up to $50 toward the cost of professional installation. This means you can take your bike to a local certified bike shop or mechanic who is comfortable working with electric bicycles.

What can happen if you ignore it

It is completely understandable to feel hesitant about taking your electric bicycle out of commission for even a few days. Life gets busy, errands pile up, and the convenience of having your trusted ride right in your garage is hard to give up. You might look at that loose pin and think it is a minor mechanical quirk rather than a critical safety failure. However, ignoring this recall transforms a manageable repair into a potentially dangerous situation. The core issue with the Super73 Z Miami SE and Z Adventure Core models is not just about parts wearing out; it is about the sudden and complete loss of braking power while you are in motion.

The hazard stems from the retaining pin in the disc brake caliper assembly. This small component is responsible for holding the brake pads in place against the rotor, which creates the friction necessary to slow down or stop your bike. When this pin loosens and dislodges, it does not gradually reduce your braking efficiency; it can cause immediate brake failure. Imagine riding down a hill or approaching a busy intersection at speed, pulling on your brake lever, and feeling nothing happen. Without the caliper properly secured, the brakes cannot engage effectively. This is not a scenario where you have time to gently coast to a stop; it is an abrupt loss of control that leaves you reliant solely on momentum and balance to avoid an obstacle.

We are not speaking in hypotheticals here. The company has already received 21 reports of these retaining pins loosening or failing entirely. While only one minor injury has been officially reported so far, the number of near-misses is likely higher than what gets documented. Each report represents a rider who experienced a sudden loss of braking capability. In real-world traffic conditions, even a second of delayed reaction due to brake failure can be the difference between a scare and a serious accident. You could collide with a car door, fall into a curb, or lose control in front of other vehicles.

Continuing to use these e-bikes also increases the risk of secondary damage to your bike. A dislodged pin means metal components are rubbing against each other in unintended ways, which can score your brake rotors or damage the caliper itself. What should be a simple, free fix now could turn into a costly replacement of entire braking systems later. More importantly, you risk your own physical safety and the safety of others on the road. The peace of mind that comes with knowing your brakes will work when you need them most is worth more than the temporary inconvenience of scheduling a repair. Please do not gamble with your stability on two wheels.

Staying safe: broader tips

While this specific recall addresses a particular mechanical failure in Super73 electric bicycles, the underlying principle applies to all high-performance personal transportation devices. E-bikes and similar powered mobility aids combine the physical demands of cycling with the complexity of electrical systems, creating a unique safety profile that requires proactive maintenance rather than reactive fixes. The most effective way to stay safe is to treat your vehicle as a hybrid system where both mechanical integrity and electronic function are equally critical to your well-being.

First, establish a routine inspection schedule that goes beyond what the manufacturer might recommend in standard manuals. For any bicycle with hydraulic or disc brakes, regularly check for signs of wear on brake pads and listen for unusual grinding noises, which often indicate metal-on-metal contact before total failure occurs. Inspect tire pressure weekly; under-inflated tires not only reduce range and handling but also increase the risk of pinch flats and rim damage, especially when carrying heavier loads typical of e-bike commuting. Furthermore, check all fasteners—particularly those on handlebars, stem, and seat posts—since vibrations from motor torque can gradually loosen bolts over time. A simple torque wrench ensures components are tightened to the correct specification, preventing sudden structural failures while in motion.

Secondly, stay informed about industry-wide safety trends by regularly checking recall databases beyond just your immediate purchase history. The U.S. Consumer Product Safety Commission (CPSC) and other regulatory bodies issue recalls for various consumer goods, including home appliances, children’s products, and power tools. Subscribing to email alerts from these agencies or following their social media channels can provide early warnings about widespread defects that may affect your specific model year or batch. This proactive approach ensures you are not relying solely on manufacturer notifications, which, while helpful, can sometimes be delayed.

Finally, prioritize defensive riding practices tailored to the capabilities of your e-bike. Because electric assist allows for higher speeds and quicker acceleration than traditional bicycles, it is crucial to adjust your stopping distance accordingly. Practice emergency braking in a safe, controlled environment to understand how your specific bike responds under hard pressure. Additionally, always wear a certified helmet that fits properly, as head injuries remain the most severe risk associated with two-wheeled accidents. By combining regular mechanical checks, staying educated on broader safety recalls, and adopting cautious riding habits, you significantly reduce your risk of injury and ensure a longer, safer lifespan for your equipment.
