Bike Carrier: The Complete Guide

A bike carrier lets you drive your bikes to a trail, a race, or a holiday without cramming them into the back seat. Choosing the right one is part safety and part convenience, and the wrong choice can scratch a frame, block your view, or fail to hold a heavy e-bike. This guide walks through every type so you buy once and carry safely.

What a bike carrier is

A bike carrier is a rack that attaches to a vehicle to transport one or more bicycles. Wikipedia's bicycle carrier overview confirms the three main mounting positions on a car: the roof, the rear trunk or hatch, and the rear tow hitch. It also notes that the first widely adopted strap-mounted carrier was invented in 1967, which is why trunk-strap racks are still so common today. There are additional designs for pickup truck beds and even for motorcycles, but for most drivers the choice is between hitch, trunk, and roof.

Note that "bike carrier" and "bike rack" often overlap. If you also want to store bikes at home, our bike racks guide covers both vehicle carriers and home storage in one place.

The three main types of car bike carrier

• Hitch-mounted carriers: Slide into a tow-hitch receiver at the rear of the vehicle. They sit low, so loading is easy, and platform (tray) versions clamp the wheels without touching the frame, which suits carbon frames and heavy e-bikes. The catch is that you need a hitch, and good models are the priciest option.
• Trunk (strap) carriers: Strap onto the trunk or rear hatch with hooks and adjustable arms. They are the most affordable and fit the widest range of cars, but they can contact the frame, block the rear window, and carry fewer bikes.
• Roof-mounted carriers: Attach to roof crossbars and hold bikes upright, usually by the fork or a wheel tray. They keep the back of the car clear for boot access, but lifting a bike overhead is hard work, and you must never forget the extra height near garages and low bridges.

How to choose the right carrier

1. Match it to your vehicle. Do you have a tow hitch, roof crossbars, or neither? That question narrows the field immediately.
2. Count the bikes and weigh them. Confirm both the number of bikes and the total plus per-bike weight limit, especially for e-bikes.
3. Consider loading effort. Hitch platforms are the easiest to load; roof carriers are the hardest. Think about who will be lifting.
4. Protect the frames. Wheel-clamp (tray) designs avoid frame contact, which matters for carbon and for expensive paint.
5. Plan for access and security. Look for a carrier that tilts or swings away so you can still open the boot, and for integrated locks.

Reputable carrier brands include Thule, Yakima, Kuat, Saris, and Allen Sports, among others. A local shop can confirm a carrier fits your exact car and hitch and show you how to load it safely.

Fitting and using a carrier safely

A carrier is only as safe as its installation. Follow the instructions exactly, tighten every strap and clamp, and do a firm tug test before you drive. Recheck everything after the first few miles, because straps settle and can loosen. Keep pedals and wheels from swinging into the paintwork, and remove loose accessories like pumps, lights, and bags that can rattle off at speed.

• Confirm the carrier does not obscure your license plate or rear lights; many regions require a supplementary light board or plate if it does.
• Balance the load so bikes do not lean heavily to one side.
• Drive a little more gently than usual, especially over bumps and in crosswinds.

Securing bikes against theft in transit

A carrier holds bikes to the car, but at public stops the bikes still need locking. Many platform carriers include cable locks, but those are light-duty and easily defeated. For any stop where you leave the vehicle, add a proper lock, exactly as you would on the street. Our bike lock guide explains which locks actually resist theft and how to use them well. When possible, park where the bikes are visible and avoid leaving them loaded overnight.

Realistic bike carrier prices in 2026

Prices vary by type, brand, and capacity, so treat these as ranges and confirm current figures locally.

• Trunk (strap) carriers: roughly 40 to 250 US dollars.
• Roof-mounted carriers (per bike, plus crossbars): roughly 100 to 300.
• Hitch platform carriers: roughly 150 to 800 plus, with e-bike-rated models at the higher end.

Spend according to how often you will use it. A carrier you use most weekends justifies a sturdy hitch platform, while an occasional trip may only need a good trunk carrier. If you regularly transport a mountain bike or a road bike, confirm the tray length and wheel-size range fit those bikes, and if you are building a full kit our cycling gear guide covers the rest of the essentials.

Frequently asked questions

What are the main types of bike carrier?

The three main car bike carriers are hitch-mounted, trunk (strap) mounted, and roof-mounted. Hitch carriers are the easiest to load and best for heavy bikes, trunk carriers are the cheapest and fit almost any car, and roof carriers keep the rear of the car clear but require lifting bikes overhead. Truck-bed and motorcycle carriers also exist for specific needs.

Which bike carrier is best for an electric bike?

A sturdy platform hitch carrier is usually best for e-bikes, because it sits low for easy loading and is more likely to be rated for the extra weight. E-bikes can weigh 20 to 30 kg or more, so always check the per-bike weight limit before buying. Many light trunk and roof carriers are not rated for e-bikes.

Do I need a tow hitch for a bike carrier?

Only for hitch-mounted carriers, which slide into a tow-hitch receiver. If your vehicle has no hitch, you can use a trunk (strap) carrier, which fits most cars, or a roof carrier if you have crossbars. A hitch can be added to many vehicles, but that is an extra cost to factor in.

Are bike carriers safe for the car and the bikes?

Yes, when fitted and used correctly. Follow the instructions, tighten every strap and clamp, and do a tug test before driving, then recheck after the first few miles. Use wheel-clamp designs to avoid frame contact, keep the carrier from blocking your plate and lights, and drive more gently than usual over bumps and in crosswinds.

How much does a good bike carrier cost?

Trunk carriers run roughly 40 to 250 US dollars, roof carriers around 100 to 300 per bike plus crossbars, and hitch platform carriers roughly 150 to 800 or more, with e-bike-rated models at the higher end. Prices vary by brand and capacity, so confirm current pricing locally and buy according to how often you will use it.
