The summer holiday season is when the space crunch shows up first: a trunk full of luggage, bikes against the garage wall, and no obvious way to get everyone and everything to the same place. Roof boxes and bike racks solve that by moving bulky gear out of the cabin and onto the roof or the hitch.
How we choose
This article looks at eight useful products for that problem: hard-shell roof boxes from Thule, Yakima, and TUFFIOM, bike racks from Allen, Saris, and Thule, and two sets of roof bars for different roof setups.
Our 8 Picks
ThuleMotion 3 XL Roof Box with GoPack Duffel Set Bundle - Cargo Storage Solution
What it is
A hard-shell rooftop cargo box with a wing-shaped profile, bundled with four 75L duffels.
Why it's worth it
The wing-shaped nose is designed to reduce drag, so this roof box is a good fit for a long family drive with luggage on the roof. The PowerClick mount clicks to signal correct fitting, and the SlideLock lid locks automatically and shows whether the box is fully closed. The four 75L duffels fit inside the box, so luggage can be packed at home and moved straight into the car. It suits a family that wants a complete packing setup and a lockable roof box.
Caveat
It needs compatible roof bars, and the XL box takes up most of the roof space.
TUFFIOM 13.4 cu.ft. Rooftop Cargo Box w/Keys, Hard Shell Waterproof Travel Roof Storage Cargo Carrier Luggage Rack, 61 in L x 27.6 in W x 13.8 in H, Dual-Side Opening, for SUV Car Van w/Cross Bars, Black
What it is
A hard-shell rooftop cargo box with dual-side opening and keyed locks.
Why it's worth it
This is a good fit for a family that wants roof box capacity without the premium price. The dual-side lid makes it easier to load when the car is parked against a hedge or wall, and the keyed locks on both sides protect the contents. The 13.4 cu ft capacity and 150 lb load limit are suitable for duffels, camping chairs and soft luggage. At under $250, it keeps the upfront cost lower than the other roof boxes here.
Caveat
It requires a set of crossbars, so factor in roof bars if the car has no factory rails.
YakimaSkyBox NX 16 LG Rooftop Cargo Carrier, 16 Cu Ft, SKS Lock, Black | Fits StreamLine Crossbars for Car and SUV Luggage and Travel Accessories
What it is
A hard-shell rooftop cargo carrier with 16 cu ft capacity and an SKS lock system.
Why it's worth it
The dual-sided opening is a practical feature for loading from either side of the car in tight spaces. The SKS lock system locks the lid and helps secure the box to the crossbars, which adds reassurance when the car is parked with gear inside. The 16 cu ft size sits between compact and XL roof boxes, giving useful luggage space without a huge roofline profile. It is well suited to a family that wants access from both sides and integrated locking.
Caveat
It is listed as compatible with Yakima StreamLine crossbars, so check your existing roof bars before buying.
AllenSports Deluxe+ Locking Quick Release 3-Bike Carrier for 1 1/4 in. and 2 in. Hitch, Model 830QR
What it is
A three-bike hitch-mounted carrier with folding arms and a quick-release locking hitch pin.
Why it's worth it
This rack is a good fit for a family that already has a hitch receiver and wants a lower-cost way to carry three bikes. The arms fold out of the way when not in use, and the internal tilt release allows lift-gate access without removing the bikes. The locking quick-release hitch pin helps keep the rack attached to the vehicle. The tie-down cradles hold each bike individually, which suits standard adult and children's frames.
Caveat
It is a frame-contact rack, so bikes with very thick or unusual frames need careful positioning.
ThuleEasyFold XT 2 Hitch Bike Rack, 130lb Load Capacity, E-Bike Compatible | EasyFold XT 2-Bike Hitch Rack | Steel, Foldable, E-Bike Compatible
What it is
A two-bike hitch-mounted bike rack with a loading ramp and a 130 lb capacity.
Why it's worth it
The folding ramp is useful for heavier bikes because you can roll the bike up instead of lifting it. The rack fits both 1.25 and 2 inch receivers and folds flat for storage when it is off the car. Ratcheting wheel straps and torque-limiting knobs help hold the bikes firmly in place. It is well suited to a family with one or two bikes that wants to keep the boot free for holiday luggage.
Caveat
It only carries two bikes, so a three-bike family would need another rack or a different plan.
SarisBike Racks, Bones EX Car Trunk Bicycle Rack Carrier, Mounts 3 Bikes (Black) with Wheel Straps, Hatch Huggers & Protect-O-Pads
What it is
A trunk-mounted three-bike rack with an arc-shaped frame and wheel straps.
Why it's worth it
This rack suits a car that does not have a hitch or tow bar because it attaches to the trunk or tailgate. The arc-shaped frame spaces the three bikes at different levels, which helps keep them from knocking together. The bundle includes wheel straps, hatch huggers and protect-o-pads, so the soft-contact parts are supplied. At 11 lb, it is light enough for one person to move between cars.
Caveat
Trunk racks depend on tailgate shape and spoiler position, so check vehicle fit before buying.
ThuleWingBar Evo, 135 cm roof bar 2-Pack Black | Premium aerodynamic load bars for an exceptionally quiet ride and easy installation of accessories. 2-pack.
What it is
A pair of aerodynamic roof load bars with a T-slot accessory channel.
Why it's worth it
This bar pair is a good fit for a family building a Thule roof-rack system because the T-slot channel works with Thule roof-box and bike-rack fittings. Thule states the WindDiffuser and TrailEdge shapes are designed to reduce wind noise and aerodynamic drag, which matters for fuel economy on a long drive. The SwingBlade end caps open to expose the full T-slot, making it easier to slide accessories into place. The 135 cm length gives a wide mounting area for larger roof boxes.
Caveat
You need the correct Thule foot pack and vehicle fit kit, as these are the load bars only.
43 in Universal Car Roof Rack, Adjustable Aluminum Roof Rack Cross Bars | with Anti-Theft Lock for Most Vehicle Without Roof Side Rail, 42.51-44.88 in Between Rain Grooves, 165 LBS Loading Capacity
What it is
A pair of universal aluminium roof crossbars with anti-theft locks for cars without side rails.
Why it's worth it
The anti-theft locks are a useful safeguard if you plan to leave the bars on the car between trips. The adjustable design targets cars with bare roofs rather than factory side rails, which is a common gap when fitting a roof box to an older family car. With a stated 165 lb per-bar capacity, it can support a loaded roof box when the weight is distributed sensibly. At under $90, it is a good fit for a family that wants roof-carrying capacity without a dealer-fit roof rack.
Caveat
Measure the gap between your car's rain grooves first; the 42.5 to 44.9 inch range will not suit every bare roof.
How to choose
How to choose the right roof boxes and bike racks for fitting a family holiday in one car
- Start with your car's mounting points. Roof boxes need crossbars: the Yakima SkyBox is listed for Yakima StreamLine crossbars, and the ComfyElect set is for bare roofs with a 42.5 to 44.9 inch gap between rain grooves. Bike racks need either a 1.25 or 2 inch hitch receiver or a tailgate shape that a trunk rack can grip.
- Decide whether the trip is bikes plus luggage or luggage only. If bikes are coming, a hitch or trunk rack keeps the roof free for a cargo box; if bikes stay home, a roof box like the 13.4 cu ft TUFFIOM or 16 cu ft Yakima adds enclosed space.
- Match the rack to the bikes. The Thule EasyFold XT is stated for a 130 lb capacity and includes a loading ramp, which suits e-bikes. The Allen 830QR is a lower-priced three-bike frame-contact rack for standard adult and children's frames.
- Total the cost before you buy. The TUFFIOM box is $239.99, but a car without roof bars may need crossbars; the Thule WingBar Evo is $222.95 and still requires the correct foot pack and fit kit.
- Pay attention to security. Options such as the Yakima SKS lock, the TUFFIOM keyed dual-side locks, and the ComfyElect anti-theft locks each protect a different part of the setup — the lid, the cargo box, or the roof bars.
Takeaway
No single roof box or bike rack fits every family car, and that is the point. Build the choice around what your car can mount, whether bikes are part of the trip, and how much roof or hitch capacity you need. When the hardware matches the vehicle, adding luggage and bikes becomes a calm part of the holiday.
