A trunk mount bike rack is the cheapest way to carry bikes on a car that has no hitch or roof rails — but it’s also the mounting style most likely to leave scratches on your paint if you buy the wrong one. Unlike hitch or roof racks, a trunk rack rests its straps and hooks directly against painted trunk, hatch, or tailgate surfaces, so the padding quality and strap design matter as much as bike capacity. This guide compares the best trunk mount bike racks for 2026 by capacity, paint protection, and price, and flags the fitment issues — e-bike weight limits, rear wiper clearance, discontinued models — that most buying guides skip.
Key Takeaways
- A record 112 million Americans rode a bike at least once in 2024, the highest participation rate since tracking began (PeopleForBikes 2024 Participation Report).
- Most trunk racks cap out around 35 lb per bike — fine for standard bikes, but under the weight of most e-bikes, which commonly run 50-70 lb.
- The Saris Bones 2-Bike is the best all-around pick for paint protection and build quality; the Allen Sports Deluxe is the best budget option.
- Trunk racks are consistently flagged in owner forums as the highest paint-scratch-risk mounting style, since straps and hooks contact painted surfaces directly — inspect padding quality before buying.
What Is a Trunk Mount Bike Rack, and Who Is It For?
A trunk mount bike rack straps or hooks onto a car’s trunk lid, hatchback, or tailgate edge, holding 2 to 4 bikes on arms that extend out from the vehicle. It’s the lowest-cost way to carry bikes on a car without a factory hitch receiver or roof crossbars, and it typically installs and removes in under 10 minutes without tools.
It’s the right choice for occasional riders who don’t want to pay for a hitch installation, renters or lessees who can’t modify the vehicle, and anyone hauling bikes a few times a season rather than every weekend. It’s the wrong choice for e-bike owners, since most trunk racks aren’t rated for e-bike weight, and for anyone hauling bikes daily, since straps wear out faster under frequent use than a hitch rack’s steel mount.
The 7 Best Trunk Mount Bike Racks in 2026
We compared trunk racks on paint protection, per-bike weight limit, bike capacity, and price — including one legacy-brand caveat: Yakima discontinued its HalfBack trunk rack in 2024, so it’s left off this list despite showing up in older “best of” roundups.
1. Saris Bones 2-Bike — Best Overall
Price: ~$219–260 | Capacity: 2 bikes | Weight limit: 35 lb/bike, 70 lb total
The Bones uses a 6-strap hook system with arced arms that hold bikes without requiring a top-tube cradle, so it fits a wider range of frame styles than cradle-based racks — including step-through and small-frame bikes that don’t sit well in some competitors’ designs. Bicycling Magazine has rated it 4.5/5, and it remains one of the most-recommended trunk racks by independent reviewers.
2. Saris Superbones — Best for Theft Deterrence
Price: ~$300+ | Capacity: 3 bikes | Weight limit: 35 lb/bike
Built on the same strap-and-arc design as the Bones, the Superbones adds retractable straps and an integrated locking cable — the closest a trunk rack gets to hitch-rack-level theft deterrence. It’s worth the premium if you’ll leave the rack loaded and unattended even briefly.
3. Allen Sports Premier — Best Value with Paint Protection
Price: ~$140 | Capacity: 2, 3, or 4 bikes | Weight limit: 35 lb/bike
The Premier upgrades from Allen’s budget Deluxe line with thicker rubber rotating foot pads that better protect paint and adjust to your car’s specific trunk angle. If you want more paint protection than the cheapest options without paying Saris or Thule prices, this is the pick.
4. Allen Sports Deluxe — Best Budget Pick
Price: Starting ~$75 | Capacity: 2, 3, or 4 bikes | Weight limit: 35 lb/bike
At roughly a third of the Saris Bones’ price, the Deluxe still offers 2-, 3-, and 4-bike capacity options with adjustable straps and foam trunk protectors. It’s a reasonable choice for families needing to haul several bikes occasionally without a big spend, though the foam padding wears faster than rubber under repeated use.
5. Thule Passage — Best Trusted-Brand Option
Price: Mid-tier, confirm current pricing at checkout | Capacity: 2 or 3 bikes | Weight limit: 35 lb/bike, 70 lb total (2-bike)
Thule’s entry-level trunk rack costs less than its hitch-mount lineup while carrying the same brand reputation for fit and finish. It’s a sensible pick for buyers who already own other Thule gear or simply want a known name backing the purchase.
6. Hollywood Racks Express — Best Simple Starter Rack
Price: Budget-tier, confirm current pricing at checkout | Capacity: 2 or 3 bikes
A straightforward strap-and-hook design aimed at first-time buyers who just need a rack for occasional trips. It won’t match Saris or Thule on long-term durability, but it covers the basics at an accessible price.
7. Bell Cantilever 300 — Best Ultra-Budget 3-Bike
Price: ~$90 | Capacity: 1–3 bikes
Individual cradle straps and a folding, powder-coated steel frame make this a mass-retail option that’s easy to find and cheap to replace if it wears out. It’s best suited to occasional, light-duty use rather than frequent hauling.
How Much Do Trunk Bike Racks Cost?
Trunk rack prices span roughly $48 to $300+, and the gap mostly buys better paint protection and strap durability rather than dramatically different capacity — every rack on this list tops out around 35 lb per bike regardless of price.

For comparison, our best hitch mount bike rack guide covers the step-up option if your car has a receiver hitch — hitch racks cost more but don’t touch painted surfaces at all.
Why Trunk Racks Are the Highest Paint-Scratch-Risk Mounting Style
Trunk racks rest their straps, hooks, and support arms directly against painted trunk lids, hatches, and tailgates — unlike hitch racks, which mount to a steel receiver, or roof racks, which contact factory crossbars rather than paint. Owner forums (MTBR, Bike Forums) consistently report scratch and rub-mark complaints tied specifically to trunk-style mounts, most often from worn or thin padding, dirt trapped under the pads, or straps over-tightened against a curved trunk edge.
The practical fix is straightforward: wash the contact area before every install, check foam or rubber pads for wear before each trip, and avoid over-cranking straps tighter than the rack’s instructions call for. Racks with thicker rubber pads — like the Allen Premier over the Deluxe — reduce this risk but don’t eliminate it entirely.
If your car has a spare tire mounted on the rear, a spare tire mount bike rack avoids trunk paint contact altogether and is worth comparing before you commit to a trunk-strap design.
Why Most Trunk Racks Aren’t Rated for E-Bikes
Every rack on this list caps out around 35 lb per bike — a limit set by strap and hook hardware, not by the vehicle. A standard bike typically falls under that ceiling, but e-bikes commonly weigh 50 to 70 lb once the motor and battery are factored in, well past what a trunk rack’s straps are designed to hold securely at highway speed.
Cycling participation has been climbing, which makes this gap more relevant every year: a record 112 million Americans rode a bike at least once in 2024, and youth participation (ages 3-17) rose from 49% to 56% over the prior study period (PeopleForBikes 2024 Bicycling Participation Report). As more of that growth comes from e-bikes, more buyers are going to run into the trunk-rack weight ceiling without realizing it until the rack is already loaded.

How to Choose the Right Trunk Rack for Your Car
Start with your budget tier, then check fitment specifics before you buy. Roughly a third of the models on this list sit under $100 (Allen Deluxe, Hollywood Express, Bell 300), a third sit in the $100-200 mid-tier (Allen Premier, Thule Passage), and the rest are premium picks over $200 (Saris Bones, Saris Superbones) — spending more mainly buys thicker padding, stronger straps, and in the Superbones’ case, a locking cable.
Before ordering, check three things your car’s shape controls: whether a rear spoiler or high-mounted rear wiper will conflict with the strap routing, whether your trunk or hatch curvature matches the rack’s support-arm angle, and whether any bike in your household is an e-bike that exceeds the 35 lb per-bike ceiling most trunk racks share.
Frequently Asked Questions
Will a trunk bike rack scratch my car?
It can, if the padding is worn, dirty, or the straps are over-tightened — owner forums consistently flag trunk mounts as the highest scratch-risk rack style since they contact painted surfaces directly. Choosing a rack with thicker rubber pads (like the Allen Premier over the Deluxe) and cleaning the contact area before each install meaningfully reduces the risk.
Can I put an e-bike on a trunk mount bike rack?
Generally no. Most trunk racks cap out around 35 lb per bike, and e-bikes commonly weigh 50-70 lb with the motor and battery included — well past what the straps and hooks are rated to hold. Check your specific rack and e-bike’s actual weight before attempting it; a hitch-mount rack rated for e-bikes is the safer choice.
How many bikes can a trunk rack carry?
Most trunk racks on this list handle 2 to 4 bikes, though actual capacity depends on frame sizes and shapes fitting together on the arms without touching. A 2-bike model like the Saris Bones is more secure for two bikes than a 4-bike rack loaded to its max, since crowded arms increase the chance of bikes rubbing against each other in transit.
Bottom Line
The Saris Bones 2-Bike is the strongest all-around trunk rack for most buyers, balancing paint protection, frame compatibility, and price. Budget shoppers should look at the Allen Sports Deluxe, and anyone leaving a loaded rack unattended should consider the Superbones for its locking cable. Whichever you choose, confirm your bike’s weight against the rack’s 35 lb-per-bike ceiling before you load it — that limit, not bike capacity, is what actually catches most buyers off guard.
