Tesla Roof Rack Guide: Crossbars, Roof Bag and Bike Mounts for Model 3 and Model Y
Share
A roof setup frees up the trunk and the cabin on a road trip, and it's the usual way to bring bikes along. This guide covers what we list for the roof and what fits which car, how much weight the roof takes, how to fit crossbars, how to load a roof bag, the two ways to carry a bike, and what to check before you drive. Product claims are the sellers', and the Tesla facts come from Tesla's manuals, linked at the end.
1. What we list and what fits your car
| Product | What it does | Fit, as the seller lists it |
|---|---|---|
| Crossbars | A pair of lockable aluminum bars with rubber pads and a T-slot on top for accessories. Front bar about 51.2 in, rear bar about 48.2 in. | Separate versions for the Model Y (2020–2025), the Model 3 2017–2023 and the Model 3 Highland. For the Model Y Juniper, check with the seller. |
| Roof bag | A soft, waterproof bag with 21 cubic feet of space, about 52 x 42 x 18 in and 4.9 kg, with an anti-slip base. It folds away when you don't need it. | Listed for all vehicles. On a Tesla, use it with crossbars. |
| Fork mount | Bolts onto a crossbar. The front wheel comes off and the fork locks into the mount, with a rear wheel holder. | Mounts on roof rack crossbars. Check that the bolts fit the slot on your bars. |
| Suction-cup carrier | Holds on with vacuum suction cups instead of crossbars, for 1, 2 or 3 bikes. | Listed as universal. Most Model 3 and Model Y roofs are glass, so check with the seller. |
2. How much weight the roof takes
Tesla's manual for its own Model 3 roof rack lists a maximum roof load of 65 kg (150 lbs), and counts everything in it: the weight of the roof rack, plus any accessory racks, plus the load. So the crossbars, a fork mount or the roof bag itself all use up part of the limit before you add any gear.
- The roof bag weighs about 4.9 kg empty, according to the seller, and 21 cubic feet fills up fast. Weigh what goes in.
- Bikes: the seller of the suction-cup carrier lists up to 20 kg per bike.
- The crossbars: the seller doesn't list a weight or a load rating, so ask before you plan a heavy load.
Check the limit for your own car and rack. If the rack's own rating is lower than the roof's, the lower number is the one that counts.
3. Fitting the crossbars
Tesla's owner's manuals say the Model 3 and Model Y support Tesla-approved roof racks using a Tesla mounting accessory. The crossbars we list are from a third-party seller, so pick the version for your exact car and follow the seller's instructions closely. From Tesla's manual for its own Model 3 roof rack, a few rules carry over to any rack:
- Clean first. Clean the roof where the feet will sit, so grit doesn't end up under the pads.
- Don't overtighten. Tesla's roof rack manual warns that overtightening may result in vehicle damage. Tighten to the seller's spec, not by feel.
- Don't modify it. Tesla says changes to the attachment system, such as additional drill holes, are not permissible.
- Lock it. The seller lists the bars as lockable, with keys. Keep the keys somewhere other than the car.
- Check it again. After the first few miles, and before every trip, check that the bars haven't moved.
4. Packing the roof bag
As the seller lists it, the roof bag is made of 600D PVC with a waterproof zipper, holds 21 cubic feet and has an anti-slip base. It straps to the crossbars and folds away when it's empty. A few things help it ride well:
- Light and bulky up top. Sleeping bags, jackets and soft bags suit the roof. Heavy items are better in the trunk, where they don't use up the roof limit.
- Fill it out. A full, evenly packed bag holds its shape and flaps less than a half-empty one.
- Straps tight, zipper closed. Pull the straps snug around the bars and tuck the loose ends away so they don't slap the roof.
- Take it off when you're done. An empty bag still catches the wind, and it folds small enough to store at home.
5. Two ways to carry a bike
Fork mount on crossbars. The fork mount bolts onto a crossbar: you take off the front wheel, lock the fork into the mount and strap the rear wheel into the rear holder. The seller lists adapters for quick release and thru-axle forks (12x100, 15x100 and 15x110 mm), mounting bolts and T-nuts, in sets of 1 or 2. In the 40 reviews we read, the average was 4.9 stars.
Suction-cup carrier. The suction-cup carrier holds on with vacuum suction cups, so it needs no crossbars. You lock the fork in front and strap the rear wheel. The seller lists versions for 1, 2 or 3 bikes and up to 20 kg per bike, and says to check the suction cups before every drive. In the 30 reviews we read, the average was 4.7 stars. Tesla's manuals don't mention suction-cup carriers, and most Model 3 and Model Y roofs are glass, so check with the seller before you fit one. One reviewer says thru-axle adapters aren't included.

6. On the road
- Speed. Tesla's manual for its own Model 3 roof rack recommends a maximum speed of 130 km/h (about 80 mph), and a speed that suits the load and the road.
- No off-road. The same manual says off-road driving is not recommended with the rack, as it could damage the car or your gear.
- Range and noise. Anything on the roof adds drag, so expect the car to use more energy and the cabin to get louder at highway speed. Bars and a bag that stay on all the time cost range every day, so take them off when you don't need them.
- Height. Bikes and a full bag add a lot of height. Watch out for garages, parking structures and drive-throughs.
- Cleaning. For its own rack, Tesla says to use only water and standard car wash liquid without alcohol, bleach or ammonium additives.

Frequently asked questions
What is the Tesla roof rack weight limit?
For its own Model 3 roof rack, Tesla lists a maximum roof load of 65 kg (150 lbs), counting the rack, any accessory racks and the load. Check the limit for your own car and rack too.
Do I need crossbars for a roof bag?
Yes. The roof bag we list straps to a roof rack, so on a Tesla you fit it to crossbars.
Do the crossbars fit the Model Y Juniper?
The seller lists the Model Y (2020–2025), the Model 3 2017–2023 and the Model 3 Highland as separate versions. For the Juniper, check with the seller before you order.
Can I use a suction-cup bike rack on a glass roof?
Tesla's manuals don't mention suction-cup carriers. The seller lists the carrier as universal and says to check the suction cups before every drive. Most Model 3 and Model Y roofs are glass, so ask the seller before you fit one.
Does a roof rack reduce range?
Yes, anything on the roof adds drag, and a loaded bag or bikes add more. Taking the bars and the bag off when you don't need them avoids the loss on daily drives.
