Drivers without a trailer hitch can use a trunk bike rack to carry bicycles on a car, hatchback, or SUV. The right carrier depends on approved vehicle fit, bike weight, frame shape, and how many bicycles you need to transport.
In November 2026, we compare 6 carriers from Saris, Thule, Allen and more, including compact two-bike designs and racks built for three bikes. Follow the manufacturer’s installation instructions and local laws, and check our hitch versus trunk rack guide if you are deciding between mounting styles.

Side-by-Side Comparison
| Rack | Bike capacity | Stated load limit | Fit guidance | Notable features |
|---|---|---|---|---|
| Allen Sports Deluxe 3-Bike | 3 bikes | Not listed | Most sedans, hatchbacks, minivans, and SUVs; confirm specific fit | Individual tie-downs; folds flat |
| Allen Sports Deluxe 2-Bike | 2 bikes | 70 lb maximum | Sedans, hatchbacks, minivans, and SUVs; confirm specific fit | Individual tie-downs; folds flat |
| Thule Gateway Pro | 1 to 2 bikes | Not listed | Not listed | Six-strap system; anti-sway cradles; cable lock |
| Soarify Sports Deluxe | 2 bikes | 70 lb total | Sedans and hatchbacks | Straps, hooks, padding; foldable |
| Saris Bones | 2 bikes | 35 lb per bike | Most vehicles, including those with spoilers | Arc-based layout; ratcheting anti-sway straps |

Vehicle approval and weight limits matter more than advertised bike capacity because they determine whether the rack suits both car and bicycles. The Allen three-bike rack does not list a load limit, while Saris states a per-bike limit and Soarify and Goplus state total limits.
Common Mistakes to Avoid
Choosing a rack from a broad compatibility claim alone can leave its hooks or straps poorly suited to a hatch, spoiler, or rear trim. Allen describes broad vehicle compatibility, and Saris says its Bones design fits most vehicles, including those with spoilers. Check the maker’s vehicle-specific guidance for your exact configuration before ordering.
Confusing the number of bikes a rack carries with its weight limit can overload the carrier. Saris specifies a per-bike limit, while Soarify and Goplus state total limits. Add the weight of the bicycles you plan to carry and compare it with the applicable limit, rather than assuming a rack without a published figure matches another model.
Ignoring frame shape and spacing can leave a bicycle unstable or let bikes contact each other. Thule says some frame styles may need an adapter, and its Gateway Pro uses anti-sway cradles. Check that every frame rests securely in its supports and that handlebars, pedals, and other parts do not interfere.
Overlooking strap placement and dirty contact points can allow movement or rub grit against vehicle paint. Install the rack as directed, secure each bicycle with its tie-downs, and inspect hooks, padding, straps, and contact areas before travel. Do not improvise attachment points when the maker’s fit instructions do not cover your vehicle.
Best Trunk Bike Rack Buying Guide
Vehicle Fit and Attachment
Vehicle fit is the first buying criterion because a trunk rack depends on attachment points suited to your car’s rear shape. Check the maker’s guidance for your vehicle’s make, model, and year, including hatch and spoiler details. A phrase such as “most vehicles” does not confirm approval for every configuration.
Attachment layouts vary, so compare strap routing, hooks, and padded contact points with your vehicle. Soarify uses straps, hooks, and padding, while Allen lists a padded lower frame and side straps on its Deluxe design. Follow the maker’s instructions and use only approved attachment points.
Drivers with spoilers or unusual rear trim should confirm fit directly when published guidance is unclear. Saris describes the Bones as suitable for most vehicles, including those with spoilers, but that general description cannot settle every vehicle-specific question. A compatible hitch rack may be a better choice if no trunk rack is approved for your car.
Bike Capacity and Weight Limits
Bike capacity tells you how many bicycles a rack is designed to carry, while its weight limit sets a separate boundary. The Allen Deluxe and Goplus models listed here carry three bikes, while other designs carry two. Choose for the number of bicycles you expect to transport, then verify their combined weight.
Check whether the maker gives a limit per bicycle or for the full load. Saris specifies 35 lb per bike, Allen lists a 70 lb maximum for its two-bike Deluxe rack, Soarify lists 70 lb total, and Goplus lists 110 lb total. Do not transfer one model’s rating to another.
Accessories that remain attached to bicycles add to the transported load, so include them when comparing weight with a published limit. Also confirm that the bicycles fit the rack’s stated capacity and support points. If the maker does not list a load limit, ask for clarification instead of estimating from the rack’s appearance.
Frame Support and Bike Spacing
Frame support matters because hanging racks must hold each bicycle securely without excessive movement or contact. Thule lists anti-sway cradles and spacing between bikes, while Saris uses an arc-based layout to place bicycles at different levels. These features can help separate bikes, but they do not guarantee fit for every frame.
Check how the carrier supports your bicycle, especially if its frame lacks a conventional top tube. Thule notes that some frame styles may need a Thule Frame Adapter for secure attachment to a hanging rack. Confirm that each bicycle sits correctly in the supports and does not obstruct the next bicycle.
Individual tie-downs secure bicycles separately, but they cannot fix an unsuitable frame fit. Allen lists individual tie-downs on its Deluxe racks, and Saris includes ratcheting anti-sway straps. Compare those support features with your bicycles’ frame geometry and the places where the rack contacts each frame.
Straps, Stability, and Paint Protection
Strap layout and padded contact points influence rack stability and how the carrier touches your vehicle. Allen lists a padded lower frame and side straps on its Deluxe design, while Saris lists rubberized feet and coated straps. Check where those parts rest against your car and whether the maker approves those contact locations.
Anti-sway features help control bicycle movement, but correct installation remains essential. Saris uses ratcheting anti-sway straps, and Thule includes anti-sway cradles. Tighten every attachment as instructed, secure each bicycle, and check the rack for movement before driving.
Paint protection depends on clean contact surfaces and correct placement, not padding alone. Inspect the rack and vehicle where they touch, and remove dirt that could rub against the finish. Follow the maker’s care instructions because even padded contact points can damage paint if the rack shifts or sits incorrectly.
Installation and Storage
Installation details matter if you remove the carrier often or prefer a simpler setup. Allen says its Deluxe racks arrive assembled, while Thule describes the Gateway Pro as tool-free to install. Those features may reduce setup steps, but you still need to confirm vehicle fit and follow the full installation instructions.
Compare a rack’s folded form with the storage space available in your vehicle or home. Allen’s Deluxe racks fold flat, and Goplus also describes a foldable design that stores flat. Check the maker’s product information for dimensions if your trunk, closet, or garage has limited room.
A trunk rack suits vehicle trips, while a bike travel case serves a different purpose for air travel. Riders planning to fly with a bicycle can compare our bike travel case guide before choosing luggage protection. Neither option replaces checking its own fit, capacity, and manufacturer instructions.
Weather, Materials, and Care
Materials and care affect how a trunk rack handles regular use and storage. Saris describes its frame as rust-free, and Soarify describes its materials as weather-resistant. Those descriptions do not eliminate the need to inspect straps, hooks, and vehicle contact points for dirt or wear.
Follow the manufacturer’s care and storage directions, and inspect attachment parts before each trip. Check straps for damage and confirm hooks remain secure. If a component appears worn or no longer holds as intended, contact the maker and do not rely on a compromised attachment.
How We Chose
We evaluate trunk racks with the Haiku Ride Score: core performance 30%, build and weather resistance 20%, ease of use 20%, compatibility and fit 15%, and value 15%. For this category, compatibility and fit means vehicle attachment guidance, bike support, and published capacity information.
We compare manufacturer specifications, compatibility information, and long-term owner feedback where available. We research and draft our guides with software tools, including AI, then run automated checks on product fit, sourcing, and our editorial rules. Our editor spot-checks guides rather than reading each one before publication. Our how we review page explains our editorial method.
Price and Value: What Each Budget Gets You
Budget
Budget trunk racks tend to prioritize straightforward strap attachment, basic bicycle support, and foldable storage over added convenience features. The Goplus 3-Bike Trunk Mount Bike Rack has a carbon steel frame, anti-sway straps, and a stated 110 lb total capacity. Buyers should confirm vehicle fit and frame support, and may give up detailed fit information or more elaborate bike separation.
Mid-Range
Mid-range designs can add practical details such as individual tie-downs, padded contact points, and flat-folding storage. The Allen Sports Deluxe 2-Bike Trunk Mount Rack lists a 70 lb maximum capacity, while the Soarify Sports Deluxe 2-Bike Trunk Mount Rack lists a 70 lb total limit. Buyers may give up an integrated cable lock or more developed bike-spacing features.
Premium
Premium trunk racks may add convenience and bicycle-separation features, but those additions do not replace vehicle approval or capacity checks. The Thule Gateway Pro has a six-strap tightening system, anti-sway cradles, an integrated cable lock, and adjustable arms. Some frame styles may need an adapter, and its fit and capacity details deserve confirmation before purchase.
Choosing Something Else
A compatible hitch-mounted rack may suit drivers who already have a hitch and want a different attachment approach. It is less suitable for drivers without a compatible hitch or those who prefer a rack that folds for compact storage. Compare our SUV rack options without a hitch if your vehicle limits your choices.
Final Thoughts
Drivers seeking a two-bike rack with separation features can consider the Saris Bones Car Trunk Bicycle Rack Carrier. Its arc-based layout and ratcheting anti-sway straps address bike contact and movement, and its stated 35 lb per-bike limit gives a clear boundary. Riders with heavier bicycles should choose a carrier with a suitable published limit.
The Allen Sports Deluxe 2-Bike Trunk Mount Rack suits riders who want individual tie-downs, assembled setup, and flat-folding storage. Families carrying three bikes can consider the Allen Sports Deluxe Trunk Mount 3-Bike Carrier, which includes individual tie-downs and a padded lower frame. Its load limit is not listed, so confirm that detail before buying.
Riders who value an integrated cable lock and adjustable arms can compare the Thule Gateway Pro Trunk Bike Rack, 2 Bike, Black. For a published higher total capacity, the Goplus 3-Bike Trunk Mount Bike Rack lists 110 lb. Buyers should weigh those features against verified vehicle fit and frame support.
Skip trunk racks when the maker does not approve your vehicle or your bicycles exceed the carrier’s limits. A compatible hitch rack may better suit drivers who need another mounting style; compare the hitch bike rack category before choosing a carrier.
FAQs
How do I check whether a trunk bike rack fits my car?
A trunk bike rack fits your car only when its maker’s guidance approves your exact vehicle and rear configuration. Check the make, model, and year, along with hatch and spoiler details. Broad claims such as “most vehicles” do not confirm a specific fit. Install the rack only at approved attachment points and follow its instructions.
How much weight can a trunk bike rack carry?
A trunk bike rack’s weight capacity depends on its specific model and may apply per bike or to the whole load. Saris states 35 lb per bike, while Soarify lists 70 lb total and Goplus lists 110 lb total. Check the exact rack’s limit, include attached gear, and stay within its bike capacity.
Can a trunk bike rack carry three bikes?
A trunk bike rack can carry three bikes when its design supports that capacity and the maker approves it for your vehicle. The Allen Sports Deluxe Trunk Mount 3-Bike Carrier and Goplus 3-Bike Trunk Mount Bike Rack list three-bike capacity. Confirm load limits, frame support, spacing, and vehicle fit before carrying several bicycles.
Do trunk bike racks fit cars with spoilers?
Some trunk bike racks are described as compatible with vehicles that have spoilers, but the exact fit depends on the rack and car. Saris says its Bones design suits most vehicles, including those with spoilers. Check the maker’s fit guidance for your vehicle before attaching hooks or straps, since a broad claim cannot confirm every configuration.
Can trunk bike racks carry bikes with unusual frames?
A trunk bike rack may not support every frame shape directly, particularly when the carrier holds bicycles in hanging cradles. Thule says some frame styles may need a Thule Frame Adapter for secure attachment. Check the rack maker’s guidance for your bicycle and confirm that its frame rests securely without interfering with other bikes.
How can I protect my car’s paint from a trunk bike rack?
Protecting your car’s paint starts with correct rack placement and clean contact points. Inspect the vehicle and carrier where they touch, remove dirt that could rub against the finish, and use padding as the maker directs. Secure straps and check for movement before driving, because padding cannot prevent damage if the rack shifts.
Do I need a hitch for a trunk bike rack?
A trunk bike rack attaches to a vehicle’s trunk or hatch and does not require a trailer hitch. Strap-on designs such as the Soarify Sports Deluxe use straps, hooks, and padding. You still need manufacturer approval for your vehicle and must follow installation guidance. Drivers comparing mounting styles can review our hitch versus trunk rack guide.
