There’s a unique sense of anticipation that builds before a ride on a new trail. You’ve studied the maps, charged your gear, and pictured the scenic overlooks. But then comes the logistical hurdle that every cyclist without a dedicated rack knows too well: how to get the bikes there. I’ve been there, wrestling a full-suspension mountain bike into the back of my SUV, Tetris-ing it around coolers and gear, all while cringing at every scrape of a pedal against the interior plastic. It’s a frustrating dance that risks damaging both your car and your bike, and it can quickly sap the excitement out of a planned adventure. The alternative—leaving the bikes behind—is even worse. This universal problem is why a reliable bike rack isn’t just an accessory; it’s an essential key that unlocks new destinations and the freedom to explore. The promise of a simple, affordable solution like the K&K Auto Accessories 2-Bike Trunk Bike Rack is immediately appealing to anyone who has ever faced this dilemma.

What to Consider Before Buying a Trunk-Mounted Bike Rack
A bike rack is more than just a metal or plastic frame; it’s a key solution for reclaiming your vehicle’s interior space and protecting your bike from in-transit damage. For cyclists, it represents the freedom to travel further afield for new routes and adventures. Trunk-mounted racks, in particular, are popular for their affordability and for not requiring a pre-installed hitch receiver, making them accessible to a wider range of vehicle owners. They are designed to be a gateway product, allowing you to transport your bikes safely without the significant investment required for roof or hitch systems. However, their convenience comes with a specific set of considerations that every potential buyer must weigh carefully.
The ideal customer for this type of product is the casual or recreational cyclist who transports one or two relatively lightweight bikes a few times a month. They likely own a sedan, hatchback, or SUV without a tow hitch and are looking for a cost-effective, easily removable solution. It’s perfect for trips to local parks, nearby trailheads, or weekend getaways. However, a trunk-mount rack might not be suitable for those with very heavy bicycles, such as full-size e-bikes that can easily exceed the weight limits. It’s also a less-than-ideal choice for owners of high-end carbon fiber bikes, as the top-tube hanging style can put stress on sensitive frames. Furthermore, if you need frequent access to your trunk or rear hatch, the strap system can become a recurring inconvenience.
Before investing, consider these crucial points in detail:
- Vehicle Compatibility & Fit: This is the single most important factor for a trunk rack. “Universal” fit is often an optimistic marketing term. You must consider your vehicle’s trunk or hatch shape, the material (some spoilers are too fragile), and where the rack’s contact points and hooks will rest. An improper fit can lead to instability and, worse, damage to your car’s paint and bodywork.
- Capacity & Weight Limit: Pay close attention to the maximum load capacity. The K&K Auto Accessories 2-Bike Trunk Bike Rack lists a 70 lb (32 kg) limit, which is about 35 lbs per bike. This is adequate for most road bikes, hybrids, and many standard mountain bikes, but it’s pushing the limit for two heavy cruisers or downhill mountain bikes and is generally unsuitable for two e-bikes. Always weigh your bikes to be certain.
- Materials & Durability: Racks come in steel, aluminum, and in this case, plastic. While steel is strong, it’s heavy and prone to rust if the coating is compromised. The K&K rack’s plastic construction is an interesting innovation to combat rust and weight, but you must also scrutinize the quality of the straps, buckles, and, most critically, the hooks and pads that make contact with your vehicle.
- Ease of Use & Vehicle Protection: A good trunk rack should be installable by one person in a matter of minutes. However, the true measure of its design is how well it protects your car. Look for soft, thick rubber or foam pads at all contact points and rubber-coated metal hooks. Without adequate protection, you risk permanent scratches and dents on your trunk and bumper.
Choosing the right rack means balancing your needs, your vehicle’s limitations, and your budget to ensure your bikes arrive safely and your car remains unscathed.
While the K&K Auto Accessories 2-Bike Trunk Bike Rack is an interesting entry in the budget category, it’s always wise to see how it stacks up against the competition, especially when transporting heavier or more valuable bikes.

Unboxing the K&K: First Impressions and Key Features
Pulling the K&K Auto Accessories 2-Bike Trunk Bike Rack from its box, the first thing we noticed was its weight—or lack thereof. At just under 4 kg (about 8.7 lbs), it’s incredibly lightweight, a direct result of its all-plastic construction. This is a significant departure from the hefty steel racks that dominate the budget market and makes handling and positioning the rack a breeze. The unit arrives folded and compact, underscoring its potential for easy storage in a trunk or garage. The manufacturer’s claim of a “heavy-duty” feel is certainly true of the main frame components; the molded plastic is thick, rigid, and feels surprisingly robust. It seems K&K has successfully leveraged plastic to create a core structure that is strong, lightweight, and completely immune to rust—a major long-term advantage. However, as we examined the smaller components, our initial optimism began to wane. The protective pads felt thin, and the bike-securing straps appeared somewhat short. The most immediate point of concern was the set of six metal clips for attaching the rack to the car; they were simple painted metal, with no rubber or silicone coating to protect the vehicle’s paint. This contrast between the innovative, high-quality core frame and the seemingly budget-cut accessory parts defined our first impression. You can see its full feature set and user reviews to get a better sense of these components.
Key Benefits
- Innovative plastic frame is strong, lightweight, and will never rust.
- Highly adjustable design offers a wide range of positioning options.
- Compact and foldable for convenient storage.
- Very affordable price point for a two-bike carrier.
Potential Drawbacks
- Vehicle protection is extremely poor; metal clips scratch paint and pads are flimsy.
- Bike frame straps may be too short for bikes with thick top tubes.
- “Universal” fit is not guaranteed and can interfere with some vehicle features.
Putting It to the Test: A Deep Dive into the K&K Rack’s Performance
A bike rack can look great on paper, but its true value is only revealed through hands-on installation, real-world driving, and meticulous inspection of its impact on both the bike and the vehicle. We put the K&K Auto Accessories 2-Bike Trunk Bike Rack through a comprehensive evaluation, focusing on the areas that matter most: how it attaches to the car, how it protects its precious cargo and the vehicle itself, and how it performs on the road. Our findings reveal a product with a genuinely innovative core concept that is unfortunately let down by critical flaws in its execution.
The Promise of Universal Fit: Installation and Vehicle Compatibility
K&K touts a patented, user-friendly design for quick, tool-free installation, and on the surface, the process is straightforward. The six-strap system is a classic trunk-rack design: two on top of the trunk lid, two on the sides, and two on the bottom. Adjusting the angle of the rack’s arms to fit the contour of our test vehicle (a mid-size sedan) was simple, and the plastic frame felt solid as we positioned it. However, the trouble began almost immediately with the very components meant to protect the car. As noted by other users, the small foam pads on the rack’s feet are not secured properly. One of them fell off just from being positioned against the trunk. This is an unacceptable quality control issue. A quick fix with super glue is possible, but you shouldn’t have to repair a brand-new product.
The bigger issue is the definition of “universal.” While the rack is highly adjustable, its footprint can create problems on certain vehicles. We saw user feedback mentioning it rests directly on the license plate of a Ford Explorer, making it unusable. We simulated this on an SUV and could see how, depending on the liftgate’s geometry, the lower feet could easily land on a license plate, light fixture, or emblem. This highlights the inherent gamble with any “universal” trunk rack: you must carefully assess your own vehicle’s rear-end design. The most glaring flaw, however, is the mounting clips. They are thin, stamped metal with a simple coat of paint. Hooking these directly onto the edge of your trunk’s paint is a surefire way to cause scratches and chips over time, especially as the rack shifts and vibrates during driving. Any responsible user, as we did, would immediately seek a workaround, such as wrapping the clips in electrical tape or inserting a piece of microfiber cloth—another DIY fix that shouldn’t be necessary. It is critical to check the latest price and availability, but factor in the need for these extra protective materials.
Material Innovation vs. Execution: The Plastic Frame and Protection Flaws
The core concept of the K&K Auto Accessories 2-Bike Trunk Bike Rack is genuinely commendable. Using a thick, molded plastic for the entire frame is a smart move. It solves the persistent problem of rust that plagues budget steel racks, making them unsightly and structurally weak over time. It also dramatically reduces the weight, making the rack far more manageable for a wider range of users. During our testing, the frame itself inspired confidence. We applied significant pressure to the arms and joints, and they exhibited very little flex, confirming user reports that the frame “does feel strong.” This solid foundation is what makes the product so frustrating—the potential for excellence is there.
Unfortunately, this excellent core is betrayed by a near-total disregard for vehicle protection in its supporting parts. As mentioned, the painted metal clips are the primary culprits. In our opinion, this is a critical design flaw. Competitors, even in the budget space, often provide rubber-coated or vinyl-dipped clips as a standard feature. To omit this is to knowingly sell a product that will likely damage the user’s vehicle. The foam pads are the second point of failure. Beyond falling out easily, they are simply too thin to adequately distribute the load and cushion the car’s surface from the hard plastic feet, especially with the weight of two bikes and the forces of a bumpy road. We strongly agree with user suggestions: anyone who buys this specific trunk-mounted carrier must invest in a roll of automotive paint protection film for the contact points. This is a non-negotiable step to prevent lasting damage to your car’s finish.
Securing the Load: Cradles, Straps, and On-the-Road Stability
Once the rack is mounted (with our own DIY paint protection), the next task is loading the bikes. The K&K Auto Accessories 2-Bike Trunk Bike Rack uses simple plastic cradles and what it calls an “Innovative Zip-Down Design,” which are essentially thick, grooved rubber straps. Loading a standard road bike with a thin top tube was easy. The cradle held it securely, and the strap pulled down tight. The real test came with a modern trail mountain bike, which features a much thicker, hydroformed top tube. This is where we confirmed a key user complaint: the straps are not very long. We were able to secure the bike, but only just barely, using the very last notch on the strap. For any bike with an even thicker frame, or many full-suspension designs with complex linkages near the top tube, these straps would simply be too short. This is a significant limitation that narrows the rack’s true compatibility.
With one road bike and one mountain bike loaded—well under the 70 lb weight limit—we took to the road. We tested it on city streets with stop-and-go traffic, over speed bumps, and finally on the highway up to 65 mph. The rack’s “Smart Stability Technology,” which refers to the 6-point strap system, held firm. We did not experience any alarming swaying or bouncing, and the bikes remained steady in their cradles. That said, as with any trunk rack, we highly recommend adding a pass-through security strap or bungee cord that loops around the bikes and the rack’s main frame for extra peace of mind. After our 30-minute test drive, we re-checked the straps and found they needed a slight re-tightening, which is normal as they settle under load. The rack is stable enough for local trips, but its shortcomings in vehicle protection and bike compatibility are significant concerns that overshadow its on-road performance. While the stability is a plus, the potential for damage is a feature that really sets it apart, and not in a good way.
What Other Users Are Saying
Our findings align very closely with the general sentiment from other users who have purchased and tested the K&K Auto Accessories 2-Bike Trunk Bike Rack. There’s a shared appreciation for the core concept; people acknowledge that the thick plastic frame feels surprisingly strong and that the price is very reasonable for a two-bike carrier. However, this initial positive impression is consistently followed by a list of the same critical flaws we identified.
The most common complaint, by far, revolves around the utter lack of vehicle protection. Reviewers repeatedly call out the flimsy foam pads that fall off during the initial setup and, more alarmingly, the “thin painted” metal clips that are “not rubber coated.” There is a clear consensus that using this rack out of the box will “very easily scratch your paint.” The second major issue cited is the undersized straps meant to hold the bike frame, with one user stating they were “not big enough to hold the bike.” These shared experiences confirm that the rack is not suitable for many modern mountain bikes or cruisers with non-standard frames. While its adjustability is noted, so are its limitations, with one user detailing exactly how it was incompatible with their Ford Explorer’s liftgate. The overarching theme is that this is a budget rack that requires immediate, user-funded modifications—gluing pads, adding foam, and applying paint protection film—to be considered usable without causing damage.
How Does It Compare? K&K Rack vs. The Competition
The K&K Auto Accessories 2-Bike Trunk Bike Rack operates in a crowded market. While its plastic frame is unique, its flaws force us to look at alternatives. For those with different needs or a higher budget, hitch-mounted racks offer a significant upgrade in stability, ease of use, and bike/vehicle protection. Here’s how it stacks up against three distinct alternatives.
1. Young Electric 2 Bike Rack Hitch Mount
- SAFE AND SECURE: Comes with soft padded hooks, that secure your bikes in place without swaying and scratching the paint. Slide down over the vertical frame...
- FOLDABLE & TILT BACK DESIGN: Users can fold up this rack to save space when not in use, convenient for garage parking. Quick release tilting down feature...
The Young Electric Hitch Rack represents a major step up in every category. As a platform-style hitch rack, it supports bikes from the wheels up, completely eliminating any concern of frame contact, which is crucial for carbon fiber or unconventionally shaped bikes. Its massive 200 lbs capacity and ability to hold fat tires up to 5 inches wide make it ideal for heavy electric bikes and mountain bikes—categories where the K&K rack struggles. While it requires a 2-inch hitch receiver and is significantly more expensive, the investment provides superior stability, security, and peace of mind. This is the logical choice for serious cyclists with heavy or expensive bikes.
2. Tow Tuff 62-Inch Steel Cargo Carrier with Bike Rack
- Heavy-Duty Capacity: Built from rugged steel, this cargo carrier supports up to 500 pounds, making it perfect for hauling heavy gear, camping equipment,...
- Versatile Design: Easily switch between a bike rack and cargo carrier by removing pins — carry up to 4 bikes securely or use the carrier for bulky cargo,...
The Tow Tuff model prioritizes versatility above all else. It’s a 2-in-1 solution, combining a 4-bike mast-style rack with a 500 lb capacity steel cargo basket. This is not just a bike rack; it’s a total hauling solution for family vacations or camping trips where you need to carry bikes, coolers, luggage, and other gear. It shares the K&K’s mast-style hanging design but offers double the bike capacity. Its primary drawback is its size and weight. This is a heavy-duty steel unit that requires a hitch and is best suited for trucks and large SUVs, making it the ideal choice for users who need maximum utility and hauling capacity, not just bike transport.
3. Young Electric 200 lb Capacity E-Bike Hitch Mount Rack
- DURABLE and SAFE: Young Electric bike rack is constructed with reinforced steel and aluminum which makes it durable and powerful enough to carry 2 bikes...
- 200 LB TOTAL CAPACITY: Built for durability and strength, this bike rack boasts an impressive 200lbs capacity, securely accommodating heavier electric...
This second option from Young is purpose-built for the e-bike revolution. It shares the high 200 lbs capacity of the other Young rack but adds a game-changing feature: an integrated ramp. Lifting a 70-pound e-bike onto a rack can be difficult or impossible for many people. The ramp allows users to simply roll their heavy bikes up onto the platform, making loading effortless and safe. It is the premium solution for e-bike owners, RV travelers, or anyone with mobility concerns who still wants to transport heavy bicycles. It exists in a completely different league than the K&K rack, targeting a specific, high-need user with a thoughtful, problem-solving design.
The Final Word: Is the K&K Auto Accessories 2-Bike Trunk Bike Rack Worth Your Money?
The K&K Auto Accessories 2-Bike Trunk Bike Rack is a product of contradictions. On one hand, its innovative all-plastic frame is a genuinely smart design choice, offering a lightweight, strong, and rust-proof alternative to the cheap steel racks it competes with. It’s compact, highly adjustable, and comes at an undeniably attractive price point. However, these significant advantages are almost completely negated by severe, bordering on irresponsible, flaws in its execution. The lack of rubber-coated clips and the flimsy, poorly-attached foam pads present a clear and present danger to your vehicle’s paint finish. The short bike straps also limit its compatibility with a wide range of popular bike types.
Ultimately, we can only recommend this rack with heavy caveats. It is suitable only for the most budget-conscious cyclist who owns lightweight bikes with traditional frames and, most importantly, is willing to immediately modify the rack to protect their vehicle. If you are prepared to glue the pads, wrap the clips in protective material, and apply paint protection film to your car, then you can get a functional, lightweight rack for a very low price. For everyone else, especially those with nice cars or expensive bikes, the risk of damage is simply too high. The money you save upfront could easily be spent on paint repair down the line. For a more reliable and secure way to transport your bikes, you are better off investing in a more thoughtfully designed product from a reputable brand or exploring the hitch-mounted alternatives.
