How to Select a Trailer Hitch
Class and receiver size still decide which rack shanks fit — even when you never plan to tow.
Watch on YouTube →Hitch for Bike Rack Only (Canada)
Only want a hitch so you can hang a bike rack — not tow a trailer? That is a common Canada shopping question, and the answer is usually simpler than full trailer shopping. You still need the right hitch class and receiver size for your vehicle and rack, and you still have to respect tongue weight. You often skip trailer wiring, brake controllers, and ball-mount geometry until the day you actually tow. This guide keeps the conversation practical.

Watch these CURT videos first
All four videos are from the official CURT YouTube channel (@curtmfg). Selection and pin basics matter even when the only thing in the receiver is a bike rack. Cover-versus-lock thinking shows up in the pin clip and in how you leave the hitch empty between rides.

How to Install a Hitch Pin
A plain pin holds the rack shank. Swap to a keyed hitch lock when the rack stays on overnight.

Bike-only does not mean shortcut the hitch install. Torque and hardware still matter before the first loaded ride.
Watch on YouTube →Anti-Rattle Clamp
Empty receivers rattle less than loaded racks. If the shank chatters on the highway, look at fit and anti-rattle gear.
Watch on YouTube →What hitch class do bike-only shoppers usually need?
Most passenger cars and small crossovers that only carry a light platform or hanging rack land on a Class 1 hitch with a 1.25 inch receiver. Many compact and midsize SUVs already use a Class 3 hitch with a 2 inch receiver because that is what CURT publishes for the vehicle — and that is fine for bike racks too. You do not “need” Class 3 just because you own bikes. You need the hitch CURT (and your vehicle maker) write for your year, make, and model, then you match the rack shank to that receiver size.
Read the vehicle-specific buyer’s guide when we have one. If the only available hitch for your SUV is Class 3, buy that Class 3 card and use a 2 inch rack shank. Do not hunt for a weaker hitch hoping it is “more bike appropriate.” The published application is the safe path.
Tongue weight mindset for racks (not trailers)
Trailer shoppers talk gross trailer weight. Bike-rack shoppers should talk tongue weight — the downward load on the hitch. Add the rack’s own weight to the bikes (and any panniers or kids’ seats you leave on). That total has to stay under the lowest of: the hitch tongue rating, the vehicle’s tongue or accessory rating, and the rack maker’s limit. Two e-bikes can surprise people. A four-bike hanging rack with heavy frames can too.
Keep the load as close to the bumper as the rack design allows, and follow the rack maker’s rules for max bike count and max bike weight. If the rear of the vehicle squats hard or the steering feels light, you are past a comfortable tongue load even if the sticker numbers look fine on paper. For the deeper trailer-side explanation, see tongue weight explained — the physics is the same, the use case is lighter.
Receiver size: 1.25 inch versus 2 inch
Match the rack shank to the hitch tube. A 1.25 inch Class 1 or Class 2 opening needs a 1.25 inch shank (or a quality sleeve adapter only when both makers allow it). A 2 inch Class 3 opening needs a 2 inch shank. Mixing sizes with a loose adapter is how racks wobble and wear the receiver. Our receiver size guide walks through the tube sizes without the brochure fog.
Also read the hitch application notes. Some vehicle-specific Class 3 cards exclude vertical hanging bike racks even though the tube is 2 inch. That is a CURT or vehicle packaging limit, not a suggestion. Tray-style racks that sit the bikes on cradles are a different load path — still confirm against both sheets.
Cover versus lock when the hitch is mostly for bikes
When the rack is off and the hitch is empty, a receiver cover keeps salt, mud, and gravel out of the tube — useful after a Canadian winter. When the rack stays in the hitch at a trailhead or overnight, a hitch lock replaces the plain pin so the shank cannot slide out. A cover does not stop theft. A lock does not weatherproof an empty tube. Many bike-only owners keep both in the hatch and switch by the day. Full decision detail lives on the cover versus lock guide.

What you can usually skip (until you tow)
Wiring
Trailer harness
Bike racks do not need trailer lights. Skip the four-flat until you actually tow — unless your vehicle guide says the harness is part of a package you already want.
Brakes
Brake controller
No trailer brakes means no controller. That decision guide waits until a real trailer shows up.
Ball mount
Drop and rise
Racks use their own shank. You do not need a ball mount for bikes alone.
Still required
Vehicle hitch card
You still need the correct vehicle-specific hitch, a solid pin or lock, and honest tongue-weight math.

Honest limits
Fitment
Vehicle card wins
Bike-only intent does not invent a hitch that CURT never published for your year. Start from the vehicle guide or year lander when those pages exist.
Exclusions
Read the hitch notes
Some hitches exclude vertical hanging racks. That is not fine print we ignore.
Weight
E-bikes add up
Tongue weight is rack plus bikes. Electric bikes push the number faster than people expect.
Security
Lock the shank
A cover is weather. A hitch lock is theft resistance for the rack left in the tube.
