Hitch, Trunk or Roof: Choosing the Right Bike Rack
The Thule T2 Pro XTR is the strongest hitch rack here, holding wheels rather than frames and tilting clear of the boot. The Kuat Sherpa 2.0 is the lighter platform alternative, and the Saris Bones EX is the best trunk mounted option for cars without a hitch.
The Thule T2 Pro XTR is the bike rack to buy if your car has a hitch receiver, since it clamps the wheels rather than the frame and tilts down so you can still reach the boot with bikes loaded. The Kuat Sherpa 2.0 does the same job in a lighter package, while the Saris Bones EX is the answer for cars with no hitch at all.
Bike racks are unusually easy to buy wrong, because the deciding factors are your vehicle’s hitch class, your bike’s frame shape and how much you can lift, none of which appear in a headline product description. We compared mounting types, stated bike capacity and per bike weight limits, whether the rack contacts the frame or the wheels, tilt and boot access, and compatibility with carbon and full suspension bikes, alongside what owners report about wobble, rattle and long term security.
How to pick the right one
Hitch, trunk or roof Hitch mounted platform racks are the easiest to load and the most secure, but they require a fitted receiver and they are heavy. Trunk racks strap to the boot lid and cost far less, which makes them the sensible choice for occasional use, though they block boot access and rely on straps you must check every trip. Roof racks keep the back of the car clear and let you tow, at the cost of lifting bikes overhead, worse fuel consumption and the ever present risk of driving into a low car park entrance.
Check the weight limit, not just the bike count A rack rated for two bikes may have a per bike limit well below what an electric bike weighs, and exceeding it is both a warranty and a safety problem. Weigh your heaviest bike, then check both the per bike figure and the total rack rating. Also check your vehicle’s hitch tongue weight capacity, since the rack itself counts towards that figure before you add a single bike.
Frame contact versus wheel clamping Racks that support bikes by the top tube are cheaper and lighter, but they are a poor fit for carbon frames, full suspension bikes, step through frames and anything with sloping geometry. An adapter bar fixes the geometry problem but adds another thing to carry. Platform racks that clamp the front wheel and strap the rear touch nothing structural, which is why they are the standard recommendation for expensive bikes.
Access, security and legal details A tilting hitch rack that swings down with bikes loaded is worth paying for if you ever need the boot on a trip. Integrated cable locks deter opportunists but are not a substitute for a proper lock when parking overnight. Check that the rack does not obscure your number plate or rear lights, since many regions require a supplementary board and lighting when it does, and confirm any rear parking sensors will not be triggered by the rack itself.
Our top picks
Thule T2 Pro XTR Hitch Bike Rack
The T2 Pro XTR holds bikes by the front wheel with a ratcheting arm, so nothing touches the frame, which matters for carbon and for anything with an unusual top tube. It tilts down with bikes loaded to give boot access and folds up when empty. Integrated cable locks and a locking hitch pin handle security.
Pros
- No frame contact suits carbon bikes
- Tilts clear of the boot when loaded
- Solid, rattle free hitch connection
Cons
- Heavy to fit and remove single handed
- Requires a two inch hitch receiver
Kuat Sherpa 2.0 Hitch Bike Rack
Kuat built the Sherpa around weight, using an aluminium frame that is noticeably easier to lift on and off the car than steel platform racks. It still holds bikes by the wheel and includes an integrated lock. The trade for the lower weight is a lower per bike weight limit, which rules out most electric bikes.
Pros
- Much lighter than steel platform racks
- Foot lever tilt for boot access
- Fits both common hitch sizes
Cons
- Lower weight limit rules out heavy e-bikes
- Premium outlay for two bike capacity
Yakima HoldUp EVO Hitch Bike Rack
The HoldUp EVO takes wide tyres without adapters, which makes it the straightforward choice if you run plus size or fat bikes. The trays adjust side to side so handlebars and saddles do not clash when two bikes sit together. It is a heavy rack, so plan on leaving it fitted rather than removing it between trips.
Pros
- Takes fat tyres without adapters
- Adjustable trays avoid bike clashes
- Sturdy under rough road conditions
Cons
- Heavy and awkward to store
- Bulky footprint behind the car
Saris Bones EX 3-Bike Trunk Rack
The Bones EX straps to the boot lid and rear panel, which makes it the practical answer for cars with no hitch or roof bars. The injection moulded arms hold three bikes and the whole rack weighs little enough to carry in one hand. Bikes rest on the frame, so unusual frame shapes may need an adapter bar.
Pros
- No hitch or roof bars required
- Light enough to store indoors easily
- Carries three bikes for the outlay
Cons
- Blocks the boot completely when loaded
- Frame contact is awkward for step through bikes
Allen Sports Deluxe 2-Bike Trunk Rack
Allen Sports keeps this simple, a folding steel frame with padded arms and six straps that secure to most saloons and hatchbacks. It carries two bikes for a small fraction of the outlay of a platform rack. Straps need checking on every trip, and the frame contact means road bikes and step through frames may need an adapter.
Pros
- Lowest outlay of any rack here
- Folds flat for storage
- Fits a wide range of car shapes
Cons
- Straps need checking on every journey
- Frame contact can mark paintwork
Hollywood Racks Sport Rider SE2 Hitch Rack
Electric bikes are heavy, and most racks quietly fail on the per bike weight limit rather than the bike count. The Sport Rider SE2 is rated for substantially more weight per bike and secures with a wheel and frame combination. It is a large, heavy rack that needs a suitable hitch class on the vehicle.
Pros
- High per bike weight rating
- Handles wide electric bike tyres
- Optional loading ramp for heavy bikes
Cons
- Very heavy rack to fit or remove
- Requires a higher class hitch
RockyMounts MonoRail Hitch Bike Rack
The MonoRail keeps the platform design but reduces how far the rack sticks out behind the car, which helps in tight parking and on short driveways. It clamps the front wheel rather than the frame and includes locks. Capacity and weight limits are modest, so it suits two conventional bikes rather than heavy electric ones.
Pros
- Less overhang than most platform racks
- Wheel clamping protects frames
- Integrated locking included
Cons
- Modest per bike weight limit
- Tighter tray spacing for wide bars

Good to know
Do I need a hitch to carry bikes?
No. Trunk mounted racks strap to the boot lid and rear panel and require no hitch or roof bars, and roof racks use crossbars. Hitch racks are easier to load and more secure, but they need a receiver fitted to the vehicle.
Will a bike rack damage my car?
A correctly fitted rack should not, but trunk racks can rub paintwork where the pads and straps sit, so keep those contact points clean and consider protective film. Overloading a boot lid or fitting a rack to a spoiler that is not rated for it is where real damage happens.
Can I carry an electric bike on any rack?
No. Electric bikes commonly weigh well over fifty pounds, which exceeds the per bike limit of many racks and most trunk mounts. Look for a rack explicitly rated for electric bike weight, ideally with a loading ramp.
How do I carry a bike with no straight top tube?
Frame supported racks need an adapter bar that clamps between the seat post and the head tube to create an artificial top tube. Alternatively, choose a platform rack that holds the wheels, which avoids the problem entirely.
Can I open the boot with bikes loaded?
Only with a hitch rack that tilts or swings away, and even then clearance varies by vehicle. Trunk racks block the boot completely, which is worth remembering when packing for a trip.
Are bike racks secure enough to leave bikes unattended?
Integrated cable locks deter a casual grab but are cut easily. If you have to leave bikes on the car, add a proper U-lock through the frames and the rack, and avoid leaving them overnight in public.
Does a bike rack affect fuel consumption?
Roof racks have the biggest effect because bikes sit in clean airflow, and the impact can be substantial at motorway speeds. Hitch and trunk racks sit in the vehicle’s wake and cost noticeably less, though they still increase consumption.
Do I need a number plate board?
If the rack or the bikes obscure the number plate or rear lights, most regions require a supplementary plate and a lighting board. Check your local rules before a long trip, since enforcement varies and fines are straightforward to avoid.
The bottom line
The Thule T2 Pro XTR is the rack to buy if your vehicle has a hitch, combining wheel only contact, a rock solid mount and tilt access to the boot. The Kuat Sherpa 2.0 is the better choice if you regularly take the rack on and off, while the Saris Bones EX gives cars without a hitch a genuinely capable three bike option.
