ROCKBROSSucker Bike Rack for Car Roof Suction Cup Bicycle Carrier Quick Release Aluminium Alloy Roof Rack for 1 Bike

It's excellent quality and the suction it's super strong. My bike is definitely not coming off. Also the red one matches the Corvette perfectly. My bike is a Trek Marlin 5 Gen 3, this bike doesn't need the extra adapters for the mount. In case you have the same one, it was a bit confusing to figure out if I needed the adapter or not. But I fully recommend this mount.

This bike rack rocks! I went from Maryland to Colorado and back. Through thunderstorms, highway speeds (yes I went up to 85 mph) for long distances. The highway was 75mph…I had to at least keep ip with traffic. Never felt uncomfortable with this on my car. Severe bumpy roads with left to right sways…did not even move. I kept checking the suction every few hours and only once was one in need of pumping it up. I love this thing! Saves so much space compared to a different kind of bike rack.Fyi. I did decide to go to hardware store to “upgrade” the locking mechanism to the forks of my bike. A 6 inch bolt and a couple of washers, lock nuts and it was good to go. Did not need this, but an engineer at heart, so thought to beef it up a little.Overall this thing is awesome and I would buy another, if needed, but I think this woll be around for a whole. Get one! You’ll love it!

The RockBros suction cup roof bike rack is a unique product that uses suction cups to secure the bike rack to the roof of a car. The first thing you'll notice is the quality and strength of the aluminum pieces, and how easy it is to mount the bike (more on that in a second). The front fork mounts with a lock similar to that on the front wheel, and the rear wheel stays in place with a strong velcro strip that wraps snugly around the bottom of the tire. As with anything else, as long as you follow the instructions to the letter and make sure everything is secured and the suction cups are securely affixed there should be no problem.Today was the first significant road test. Even driving my car as fast as 75, and consistently 60, the bike stayed rock solid on the roof. No wobbling, nothing. It held up very well.As with any roof rack, the biggest challenge I have found - especially if you have an SUV -is that you'll need a step stool to get the bike up there. You'll also need to hold the bike in a specific way. If not careful this may result in the fork making small gouges on your roof, as I experienced today. However, once you develop the strength and skill to lift the bike up and down, the rest is easy. And again, it is VERY easy to set up the bike rack, mount the bike, and unmount the bike.That said, I don't know how long the suction cups are going to last, and I haven't taken this for a 50-100 mile test yet, but the early returns are encouraging. Especially if you don't have a roof rack, this is a pretty good option.

My road bike was on the roof of my car, secured with this rack, while we drove through Hurricane Debby on I-75 in Florida. 80mph cross winds did not have any impact on the security of the bike! This little rack has impressed me with multiple road trips at 80mph road speeds. No issues! I’ve also used it with my gravel bike and full suspension mountain bike. It’s great!

Drove from Orange County, California to Chicago with my bike on my roof. Not a single problem. Strong winds, drive fast at times, and the bike remained firmly planted. I erred on the side of caution and reset the suction every 2 hours or so, but probably wasn’t necessary.Highly recommend this product.

The mount held the bike in place while it lasted. Unfortunately the pressure buttons you pump to lock the mount in place simply popped out after only 3 months rendering it useless. I would save the money and get something that’s actually going to last.

I was hesitant to get this, but I'm glad I did. If your vehicle is like mine and limited in its capacity to have a proper roof rack, or you are looking for a lesser expensive option, this is it.I kept looking through my sunroof sporadically during the first few times I used it, but now I don't even bother once I've set the suction cups and mount the mountain bike.This has taken my mountain bike hundreds of miles, some on highway at 80+mph, and some on twisty B roads with less than ideal road surfaces. I even drag raced my friend while I had my bike on the roof and this thing was solid. I will simply say for context that the car goes 0-60 in 3.5s and does the quarter mile in just about 12 seconds flat. For those that don't understand the context, rest assured it is a violent acceleration and the bike mount did flawlessly.I am completely confident in this product at this point and I'm glad I saved the money and decided not to buy the Seasucker system.Note: My bike does have a Boost 110 axle so I had to purchase the adapter for like $10, also found here on amazon

This bike mount is awesome! Gave it a test run for about an hour drive at 55-65 mph and it was flawless! Easy to put on the top of my vehicle and stayed secure the entire way.Then the true test, 5-6 hours on the interstate! I checked it several times and never had any issues. It felt secure at each stop and I never had to adjust the suction or straps.Mounting was simple and quick. (You do need to carry some type of water application to wet the suction cups. I used a spray bottle, but they definitely need a little water to make the best deal). I’m once mounted on the vehicle I removed my front wheel and used the provided skewer (no need to take it fully out, just loosen) and secured my front fork.Note: make sure to use the provided strap to secure your crank prior to loading your bike. Not a deal breaker but makes life easier so your crank doesn’t spin and gash your vehicle.Secured the rear mount after loading the bike, to make sure the alignment was correct. Again using a little water to make the suction much better. Then strap in the rear wheel and you are on your way.This mount performed perfectly!
