Trailer Hitch Carrier buying guide — what to know before you buy

A trailer hitch carrier (towbar carrier or trailer coupling) is the structural receiver assembly that attaches to the vehicle's tow hitch or rear bumper to accommodate a bike rack, cargo carrier, or accessory platform. Carriers allow luggage, bicycles, or sports equipment to be transported on the rear of the vehicle without the need for a roof rack, reducing wind resistance and the effort of lifting heavy loads. Correctly rated carriers are essential for safe use — overloading the receiver or fitting an incompatible carrier creates a dangerous handling situation. At CarParts247 we stock towbar-mounted carriers, cycle carriers, and receiver accessories.

Towbar mounting and load ratings

Trailer hitch carriers must be matched to the towbar's D-value and tongue weight rating. Exceeding these limits compromises vehicle handling and brake performance.

Check the towbar's maximum nose weight (tongue weight) — typically 50-100 kg for tow balls
Bike carriers must not exceed the towbar's maximum supported weight rating
A carrier's payload rating and the bike weights combined must stay within the nose weight limit
Ensure the carrier does not obstruct the rear number plate — a plate extender is often required
Check that rear lights are not obscured — a light board is legally required if lights are blocked

Fitting and security

Correct fitment prevents play, vibration, and the risk of the carrier detaching under load.

Use anti-tilt devices or hitch stabilisers to eliminate receiver play
A security lock pin prevents theft of the carrier assembly
Carry out a visual check of all load straps and attachment points before each journey
Spread load as evenly as possible between left and right to prevent swaying
Recheck all attachment points 30 minutes into a journey when components have settled

Frequently Asked Questions

What is a trailer hitch carrier?

It is an accessory that slots into a standard 50mm tow ball or receiver hitch and allows a cargo platform, bike rack, or other carrier to be attached to the rear of the vehicle.

How much can a towbar carrier hold?

It depends on the towbar's nose weight rating, which is typically 50-100 kg. Always check both the towbar and the carrier ratings and stay within the lower of the two.

Do I need to use a number plate board with a carrier?

Yes, if the carrier and its load obscure the vehicle's rear number plate. A number plate light board must display the same registration number and be illuminated when driving in poor visibility.

Can I use a trailer carrier without a towbar?

No. Towbar-mounted carriers require a fixed tow ball or receiver hitch. Roof carriers are an alternative for vehicles without a towbar.

Is a trailing arm or platform carrier better for bikes?

Platform carriers sit the bikes low and are generally easier to load and more stable. Arm carriers (hanging) are lighter and cheaper but can cause contact between bikes. Platform carriers are recommended for heavier or more valuable bikes.
