Putting a bike rack on a car comes down to six steps: pick the rack type that suits your car, check the fit, mount it, load the bikes, strap them down, and check everything before you drive. Here’s how each step works for hitch, trunk and roof racks.
Quick answer: a hitch rack slides into your trailer hitch receiver and locks with a hitch pin; a trunk rack hangs on the trunk or hatch with straps and hooks; a roof rack clamps onto crossbars. Load the heaviest bike first (closest to the car on most hitch racks), strap the frame and wheels, then shake-test the rack and recheck the straps after a short drive.
The Three Main Types of Bike Racks
| Type | How it mounts | Good to know (REI) |
|---|---|---|
| Hitch rack | Slides into a trailer hitch receiver | Easy loading with moderate lifting; many tilt for rear access; match your receiver size |
| Trunk rack | Straps and hooks on the trunk or hatch | Most economical; carries 1–3 bikes; limits trunk access; bikes may sway |
| Roof rack | Clamps onto roof crossbars | Keeps the rear clear; needs lifting; watch low-clearance garages |

How to Use a Bike Rack on a Car in 6 Steps
Step 1: Check the Fit
For a roof rack, use the Thule or Yakima fit guide for your make, model and year. For a hitch rack, match the rack to your receiver size. For a trunk rack, check the rack’s own fit list for your car, especially if you have a spoiler. Also check your vehicle manual: REI says to know the roof’s maximum load before installing a roof system and to verify tongue weight capacity before using a hitch mount. Count the rack and the bikes together, and stay within the rack’s total and per-bike limits.
Step 2: Mount the Rack
- Hitch rack: slide the rack’s shank into the receiver, line up the holes, insert the hitch pin and clip or lock it. Tighten any anti-rattle device the rack has, then push and pull the rack to check it doesn’t wobble.
- Trunk rack: clean the paint where the pads sit, set the rack on the trunk or hatch, hook the straps on the panel edges in the order your rack’s instructions give, and tighten them evenly. Don’t hook onto glass or a plastic spoiler unless the instructions allow it.
- Roof rack: clamp the bike mount onto your crossbars per its instructions. Some hold the bike with both wheels on; others need the front wheel removed and the fork clamped.
Step 3: Load the Bikes
Lift with your legs. On hitch and trunk racks, the heaviest bike usually goes on first, nearest the car; follow your rack’s instructions. Alternate the direction of the bikes if the handlebars or pedals touch. If a bike has a sloping or step-through frame, REI notes it may need a top tube adapter on cradle-style racks.
Step 4: Strap the Frame and Wheels
Secure the bike with your rack’s clamps, cradles and straps as its instructions specify. REI recommends securing the tires on trunk and hitch racks with a strap or bungee so bikes don’t sway and bump each other.
Step 5: Check Before You Drive
Shake the rack and each bike. Make sure nothing blocks your lights or license plate; fix any obstruction before you drive, in a way that meets local rules. Lock the bikes to the rack and the rack to the car if your rack has locks.
Step 6: Recheck on the Road
Pull over after a short drive and recheck the straps, which can settle. Remember the bikes are there: hitch racks make the car longer, and roof bikes add height at garages and drive-throughs.

Black Friday Tip and Gift Idea
Black Friday tip: if you plan to buy a bike rack on Black Friday 2026 (November 27) or Cyber Monday (November 30), decide the type now and check the fit: receiver size for a hitch rack, the fit list for a trunk rack, or crossbars for a roof rack. Weigh your bikes too. On the day, check the current price on Amazon rather than a “was” price.
Gift idea: wheel straps or a top tube adapter can suit a rider who already has a rack; check the strap length, and for the Allen adapter, that the bike has 18–27 inches between headset and seatpost. Before gifting a full rack, confirm the recipient’s car, mounting system and their bikes’ sizes and weights.
FAQ
How do you put a bike rack on a car?
It depends on the rack type. A hitch rack slides into the trailer hitch receiver and is held with a hitch pin. A trunk rack hangs on the trunk or hatch with straps and hooks. A roof bike rack clamps onto roof crossbars. Follow the instructions for your exact rack.
Can you put a bike rack on any car?
Not any rack on any car. REI points to Thule and Yakima fit guides for roof racks, says hitch racks must match your receiver size, and notes that a receiver can usually be added to a car that doesn’t have one. Trunk racks have their own fit lists, so check yours for your exact car.
Which bike rack is easiest to load?
REI says hitch racks let you reach your bikes with moderate lifting, unlike roof racks. REI also says platform-style racks handle a wider variety of bike sizes and shapes.
Do I need an adapter for a step-through bike?
Often, on hanging hitch racks and trunk racks. REI notes some bikes, particularly women’s or kids’ models, may need a top tube adapter. The MaxxHaul listing, for example, says it’s designed for bikes with a horizontal top bar.
Is it safe to drive with a bike rack?
Yes, if the rack fits your car, stays within its limits and the bikes are secured. Count the rack and bikes together against your vehicle manual’s roof load limit (roof racks) or tongue weight capacity (hitch racks), respect the rack’s total and per-bike limits, and strap the wheels on trunk and hitch racks so bikes don’t sway.
Do trunk bike racks damage your car?
They can scuff paint if the pads or hooks sit on dirt or the straps loosen. Clean the contact areas first, follow the rack’s fit instructions, and recheck the straps.
