Suction cup bike rack

I recently got rid of my SUV and now have a small sedan.

I don't like using a rack that attaches to the trunk as I'm afraid of chipping paint. I would like to add a tow hitch and then I can add a rack to that, as required.

For now, does anyone have any experience with the Rock Brothers ones?

I think as long as you're not attaching it to glass- you should be cool.

I've seen issues of people attaching them to large glass panels- and the glass shattering...

Personally, I wouldn't trust it. But that's just me. I think I'd spend more time looking in the rear view mirror than at the road making sure the bike is still there! Me: "What if it rains? What about big bumps? What about unexpected jerky evasive maneuvers like in the movies?" I can't get a suction cup to hold my cell phone holder to the windshield or my soap holder to to my tub wall reliably; I'm not trusting that my bike will stay put.
i might be too cautious and paranoid.

I put on a hitch and a Kuat carrier. I'll never look back. If you are planning on a hitch, why bother with suction?

I'm a big fan of a hitch and a Kuat. For one bike I will throw it in the back of my SUV. But any time I need to haul people and bikes, I have a 4-bike Kurt that has been great.

Why try the suction (or even using a removable bike rack)?

We bought a 2024 Kia Forte and no one locally has the hitch. Right now they're about $280 plus shipping for just the hitch. I was told they're high priced because the car had been "redesigned". I suspect that is BS. I'm waiting for a cheaper aftermarket one to appear before I get one.

i was also interested in the suction idea because I could leave it in the trunk for when a deal pops up. I'd prefer to not leave a rack mounted semi permanently.

Just wondering if anyone had used one.

Agreed. This is one place where I would absolutely not try to pinch pennies.

One thing to be careful about suction cup racks is if you have aluminum body panels on your car, the suction cups can actually pull up the panel so hard that you can end up with slight bulges on the panel
in a car forum I'm a member of, a guy had this happen to the aluminum trunk lid of his car. I don't remember what car he had, but we think that maybe he just pumped up the suction on the cups too much. Many cars now have aluminum body panels, so it's good to know what you are putting those suction cups on to avoid possible damage.

Classic bike forums lots of opinions and rumors however no one has actually used the product. I myself also has no experience however talked to a guy at an event who used on on his Tesla Model 3. Mentioned no issues and very convenient.

Have you seen the thread about Shimano "bonded" cranks coming apart?

This is along the same lines; A bond between two parts, where degradation of the bond is difficult to detect and can fail quickly and without warning, hence the actual engineering term of "catastrophic failure mode".

I've seen fishing rod holders with suction cups, and didn't trust them for that. Which is why a bunch were on clearance dirt cheap, and I tried using them to hold the boom and mast in place on my small sailboat when in storage on the hard, never moving. Came back, had come unsucked, don't know when. Not a sound solution. Fortunately during my test, I had rigged backup lines to catch the boom and mast if they came loose, which they did.

Now, if it was like an old car ski rack I had, with straps and clips/hooks to the door opening, and suction cups just as "landing gear" to keep it from sliding, and the strap putting constant downward pressure on the cups, different story.

The Uhaul is quoting $500 for a hitch on my spouse's Tiguan. Not a small chunk of change. So for now, only the Mini. But the Mini is only for bikes so no wiring harness, that adds $200 to the Tiguan, it would be only $300 with out it.

I have used a Saris Bones in the past. Usable, but not a great fit on a Mazda3 hatch. If you do get the suction, make sure the cups and your car surface is clean so you don't get scratches. The Saris came adhesive pads for the bumper to reduce scratches. I never had an issue with scratches due to the upper arms of the Saris.

The frame is steel, but I wanted a weight weenie bike. It comes in at 7.0kg. I could get it to 6.9, but I am lazy and the 100grams ain't cheap. I got it in 2009, so 15 years now.

Since the "hitch" thing has been followed up on- I got a Curt hitch on my car- I think it's something like a 200# limit. The rack is a different thing... It's a Saris Freedom 2. I "like" it, but I don't love it.

I like that it doesn't mash my fenders, I like that it bears the bike weight on the wheels, I love the 'lean away so I can open the tailgate' thing. I *HATE* that it doesn't fold up and save any space. Seriously- It sticks out like 3 feet, folded up it's like 2 feet 8 inches.

I have Sea Sucker for load bars for my Mustang Mach E *and* a hitch mount platform-style bike rack (Inno 4 bike). I prefer the hitch mount as it keeps the bikes out of the wind (less chance of road debris hitting them). I like the platform over the hanging style as it squeezes the wheels (ie tires) to hold the bikes in place and no pressure on the frame or paint.

The load bars are to put a luggage pod, or skis, or boats up top.

Since Rockbros doesn't make a load bar option, I went with SeaSucker. But I would have no issue using Rockbros. Everyting else by them (saddles, lights, pedals etc) I have used have all been high quality, solid.

Trace Velo has a nice review:

I am on the fence. Most of the suction cups that have released are due to temperature changes, i.e. windshield cups holding EZ pass.
I always moisten the cup before applying to a very clean surface.
The tandem Kayak is a bit heavy for me to load on the roof. There is an suction cup attachment to place on a surface, in my case glass, to feed the keel. It works OK but the slight curve of the XJ hatch glass sometimes doesn't hold the suction. Alignment is critical. That is only for a 10 min use.
Deforming AL panels says a lot about the force generated. There is a dent or two I would like to try that suction solution out on. If you get a slight deformation, try dry ice to get it to shrink.

I'm absolutely cheap AF and I have had the rockbros version for several years now. Thousands of miles, and it works as designed. I have traveled at higher rates of speed than necessary, and it just works. I also have a cycling buddy who has had one longer, which has also been trouble free for him as well.

It's pretty workmanlike, but a decent buy for the price.

My next investment will be a hitch variety. I'm not getting any younger, and it's just best overall.
