Ever heard of the
giant squid? What about that time, back in 2016, when a guy climbed up the side of a 58-story glass highrise in New York? A 40-foot long squid and that daredevil both depend on the power of suction cups, as does Sea Sucker with an entire range of bike racks and accessories based on that same principle. Actually, Sea Sucker is pretty insistent about referring to them as ''vacuum mounts,'' but you get the idea. Sea Sucker's angle is that by using these powerful suctio...er, vacuum mounts to attach their racks to vehicles, they're able to offer a much more versatile, easy to use bike transporting solution. It also means they can do without a rat's nest of straps or a hefty bolt-on hitch.

www.seasucker.com The Mini Bomber is a two-bike rack that consists of a 3/4'' thick polyethylene (AKA plastic) deck with four vacuum mounts that's home to the two fork holders, as well as two separate vacuum-mounted rear wheel holders.
Sea Sucker says that it can hold up to two 45 lb bikes, and the vacuum mounts can grab onto metal, glass or fiberglass surfaces. The entire kit weighs just 12 pounds, and sells for $489 USD.
Instead of bolts and straps, the Mini Bomber depends on the power of vacuum mounts to keep your bike safe. Each of the six mounts is rated to a 210 lb pull force.
DesignSo, how the heck does this thing hold onto your car? It's as simple as pushing all of the air out between the cup and whatever surface it's grabbing a hold of, with the difference in pressure between inside and outside the cup giving it its gripping power. Sea Sucker says that their 6'' vacuum cups have a "pull rating" of 210 lb, which is roughly the weight of one e-bike. I jest, but a cup's rating is usually calculated by multiplying its surface area by the atmospheric pressure.
The vacuum pump (left) integrates with the mount, and it pulls air out from between the mount and the surface through that small port (right).
Let's look at the most important part first: the vacuum mounts that seem to scare so many people. They measure 6'' across (there are 4.5'' versions for other uses) and include an integrated vacuum pump that you use to draw air out from between it and whatever surface you're attaching it to.
The vacuum pump includes an orange indicator line that lets you know when it's grabbing firmly enough, and they're actually modular and can be replaced on their own for just $12 USD. If you need just the vacuum pad, the 6" size goes for $14 USD, and you can also get different accessories to hold things like ladders, GoPros, flexible arms, fishing rods, or cup holders. Sea Sucker also has setups for marine and tech use, too.
The plastic deck is 3/4'' thick and each mount can hold 210 lb, but the whole setup weighs only 12lb.
For the two-bike Mini Bomber that's reviewed here, Sea Sucker attaches four vacuum mounts to a thick but somewhat flexible deck that has just enough give in it to match a car's curved roof. Aluminum fork mounts bolt to the top of the deck, and there are different angle settings so you can keep each bike's handlebar from smashing into its neighbor. The rack comes stock with quick-release fork mounts that are probably useless to a lot of mountain bikers these days, so you'll have to spring for some thru-axle mounts that can be had in Boost and non-Boost sizes for another $29.95 USD. If you need to carry a bike with a 20mm thru-axle fork or a Lefty, they also sell Fork Up's adapters $39 - $75.00 USD. Front wheel holders are available, too, but only for quick-release hubs.
The bike's rear wheel is held onto the back of your car using a single vacuum mount and a 22'' long hook-and-loop strap that should be long enough for the tallest of rims and widest of tires. It's also worth pointing out that all of the Mini Bomber's hardware is stainless steel, a nice touch for anyone who lives in a wet climate or close to the ocean.
The whole idea behind Sea Sucker's racks is that they're quick and easy to install and remove but, as you might guess, that presents a bit of a challenge when it comes to security. Turns out that vacuum cups can be used to climb the side of a building or kill a sperm whale, but they're easily defeated by your local meth enthusiasts.
Sea Sucker does sell anchors meant to go inside your trunk or cab and have a cable lock ran through them, but that seems like a light-duty solution to me.
It's certainly sleeker-looking than a strap-on rack.
InstallationInstalling any type of bike rack correctly is obviously of high importance, but I feel like it's extra critical with the Mini Bomber. That said, the job should only take a few minutes, and I'd rate the mechanical skill level required a 2/10.
First thing first, you have to make sure that wherever you're putting the vacuum cups is clean and dry, and they're not going to work on the roof of your '87 Tercel wagon if it's rusting away into a convertible. Sea Sucker also says you should give the vacuum cups a quick look and clean before each use, for obvious reasons. These little guys will stick to a lot of different surfaces, and even underwater (just in case your GPS leads you astray), but wherever you put them can't be too flexible, either.
The middle of my car's roof is about as stiff as an empty tin can, so that'd be out of the question.
If you pass those checks, all you need to do is to push the cup gently against the surface and start working its vacuum pump. It doesn't take long, maybe 15 - 20 pumps, and the orange band on the plunger disappears to let you know you've done enough. It'll also let you know if the cup is losing its grip; the orange band being visible means that you should investigate.
Apply the same routine to all of the vacuum cups, including the rear wheel holders, and you're all set.
The plastic deck is pretty stiff but it does have just enough flex in it so as to match a roof's curved cross-section. It can still take a good amount of pressure to get the deck to flex enough so the cup can suck itself down onto the roof, but that will depend on your car's shape.
Because our kind is mostly used to tray-style or strap-on racks, or tailgates, it's probably worth pointing out a few, umm, quirks of getting the Mini Bomber on your car and your bike on the Mini Bomber. Most importantly, know that Sea Sucker does point out that their racks aren't set-and-forget type of things, and also that they'll need a look every few hours. Not for the absent-minded, then. And having to clean wherever you're putting the vacuum cups is a bit of a PIA when you're late for a ride or just wanting to get to the mountain. On top of that, I suspect that putting a vacuum cup on a dirty car could lead to some paint damage over the long run, but I wasn't going to test that. Also, the suction surface of a cup has to be undamaged, of course, so you can't just go tossing these things into the back of your garage until you need them.
Because the fork and rear wheel mounts are completely separate pieces of hardware, you'll need to install the deck first and then the bike before you'll know where you should put the mount for the rear wheel. I guess you could strap the cup to the wheel first and then put the bike on the rack, too.
The Mini Bomber isn't set-and-forget; you'll need to check the vacuum mounts every few hours.
PerformanceFirst, there's no denying that, next to throwing it over a tailgate, a hitch mount, tray-style rack is the easiest way to carry a mountain bike around, especially when it comes to loading your bike. It's not exactly difficult to get your bike on the Mini Bomber - if you can lift it over your head, you can do this - but it can be a little cumbersome to get the fork's axle through and threaded in while simultaneously keeping your bike from tipping over onto your car. I definitely recommend putting your bike on the side of the rack that lets you slide the axle in from the outside rather than the inside - the former is much easier to manage.
Because the rack has such a low profile - it sits only a few inches above the car's roof - it doesn't look like the vacuum cups would be able to hold your baby up if you're doing a bit of 'spirited driving.' The bike is surprisingly solid, though, which does make sense given that each vacuum cup is said to hold up to 210 lb of pulling force, which is 840 lb across the Mini Bomber's deck. If you grab the bike and try to shake it hard side to side, it actually feels more solid and secure than on some tray-style racks I've used. Heavy crosswinds? I wouldn't even give it a second thought. Hard e-brake turn? Don't mind if I do, and neither will the Mini Bomber.
When you install the two fork mounts, you can choose to angle them via three different positions. I wasn't thinking and bolted both fork mounts down at the same angle, which isn't ideal if you're carrying two bikes with wide handlebars - the inside ends will touch. I'd like to see each fork mount position moved outboard on the deck by another inch or two so you'd never have to think about, but angling the mounts is the built-in solution that works.
It's when you don't need a bike rack that the Mini Bomber comes into its own. It takes about 30-seconds to remove; all you need to do is pull up gently on each of the vacuum mount's tabs, at which point they'll pop off with no effort. And since the entire thing weighs just 12lb and isn't exactly big, I can just put it in my car's trunk until I need to use it again. It will even slide under the seats of many cars or trucks without issue.
Is that a spoiler or a bike rack? No, it's a bike rack.
The Mini Bomber is going to be the ticket for a lot of riders who can't use (or don't want to use) a more traditional rack, but there are a few quibbles that bear repeating.
As mentioned above, you can't just throw this rack onto your car without a bit of prep, especially if your car is dirty. The vacuum mounts prefer a clean, dry surface to grab onto, and you'll need to take the time to wipe down whatever part of your car that you're attaching them to. It only takes a few minutes to do, so please do it. Also, you shouldn't mount the cups onto a flexible surface, or one that's been wrapped.
The other thing to keep in mind is that this system isn't set-and-forget like a trailer hitch-type rack usually is. Sea Sucker suggests taking a look at the vacuum mounts every few hours during a road trip - remember, if they're losing power, you'll be able to see the bright orange band on the vacuum pump. Also, the cups are made of soft rubber so they can conform to different surfaces and the rubber is certainly not indestructible. If a cup is damaged, it won't be able to hold onto the surface as well as it should, so care needs to be taken with the Mini Bomber.
Vacuum mounts or straps? Choose the former if you're installing and removing the rack all the time.
So, would I choose a strap-on rack like Saris' much less expensive Bones two-bike rack? I
reviewed the Bones last year and while it carried bikes just fine, I eventually got tired of having to deal with all those straps that were a PIA because I didn't want it on my car all the time. The Mini Bomber has its own set of quirks, of course, but it's easier to install, easier to deal with when it's not on my car, and easier to get bikes into. I still have the Bones rack, but I'll be sticking with the Mini Bomber.
As for which one I trust more, I'm going to say that it's a tie. I'll glance in my rear view mirror every ten minutes regardless of the rack I'm using, and I'll check both types at every gas or food stop. It took a few weeks for me to trust the vacuum cups, if I'm honest, but now I don't even think about them until it's time to have a look.
Pinkbike's Take: | The Mini Bomber comes with a handful of quirks that you wouldn't normally see with a strap-on or tray-style rack, and it sure seems a bit pricey for what it is, but it's also going to be the ideal solution for a small percentage of riders who either can't use or don't want to use a traditional rack. This isn't the setup for someone who's hard on their stuff, either. All that said, if your vehicle doesn't accept a receiver, and strap-on racks seem a bit hokey, you might be the ideal Mini Bomber owner.— Mike Levy |
That's it, I'm gone...
....I know your in the bike industry you can't afford a Sprinter.
no thanks.
We use woods power grips. The same ones they use to install plate glass on skyscrapers. They actually have audible alarms in them to warn that they are losing suction. Constantly cleaning the cup, cleaning and lubing the seal assembly and also having to wet the surface for best results. Multiple brands, models, new, old doesn't matter, they are not 100% reliable.
Like Mike says - if you have a hitch receiver then this rack probably isn't for you.
>when the front parts is sucked down onto the roof it bends the roof panel into shape. Not pleasant if you're fond of your car.
>no locking mechanism so you can't leave it whilst you pop into the service station or wherever
>suction pads are temperamental - the anxiety of maybe losing your bike on the motorway just isn't worth it.
Sorry sea sucker, nice idea but it's got it's floors...
Curious - if that Downcountry machine flew off and got run over by a speeding SUV on the Sea to Sky - would Pinkbike have to pay the bill?
> They're used in industrial applications for lifting glazing into new buildings etc. Some bespoke glass would easily dwarf the cost of our bikes and theyre used without issue.
But obviously, briefly lifting glazing into installation position and driving a load four hours in variable road and weather conditions are two very different applications.
That said, I do look forward to what he has to say, always get a kick out of his stuff
Let's not forget that no one will ever check the vacuum strength every "few hours" or so. I wonder how the insurance claims will go if that thing fails and releases the bikes onto the motorway or when it completely dents the roof panels.
Either way I have a hitch mounted tray rack on my car so I won't be using this. But for those who don't travel long distances and can't use a hitch mount rack, this is a great "no frame contact" rack option vs those crappy strap racks.
Based on everything I've seen in my experience and testing, I wouldn't trust hanging a $400 bike off the roof with vacuum cups, let alone something much more expensive. It's a great concept in terms of temporary mounting, but it's definitely more temporary than would trust!
After leaving the highway onto mountain road I was sure the bike lays to the side on every curve, despite 30-40kph speed.
So as the emergency measure for some friends / family car these may be OK, but no way this could be primary rack.
Suction Cup: $14 (* 5 = $70)
Bike Rack = … $489
Polyethylene tray/straps = $489 - $130 = $359 … And here I thought carbon was an expensive plastic...
You only check your rear view mirror once every ten minutes? Given the crappy drivers on the S2S highway, id suggest more frequent checks....
He uses SeaSuckers to attach his bike to his rental car. They easily fit in his bike case, and are basically guaranteed to work with whatever car he ends up with.
Perfect (though stupid expensive) for that application, hard to imagine a reason to get one otherwise.
Bit obsolete now because I normally use my RV now when I go out for a ride, but great piece of kit nonetheless.
I’ve also not seen any paint damage from using them.
The biggest con for me is the security aspect, you can’t just leave your car parked somewhere with a bike on. It does take probably 5 minutes extra each way to mount the rack each time too.
I didn't get these for day to day use as a hitch mt rack better fits my needs. However, was looking for something that could be taken on plane trip with bikes going on rental car, or if we were in a temporary situation where we needed to bring an additional bike beyond the hitch rack's capability.
Did not see any damage/concern with the car paint.
The drawback for myself is for travel purposes, at present, they do NOT have an 20 mm fork adapter for a downhill bike.
The company responded to my inquiry to get it shipped on short notice with proper adapters.

That said, I thought this was like a $189 solution for your vehicle that wasn't meant to haul a bicycle. At five bills, just get yourself a 1 1/4" hitch installed and go with with a real rack. Keep up the advertising, Sea Sucker...I ain't fool enough to buy it.
"WTF is up with all these circular scratch marks and dents? I wish your ad had shown photos of them so I wouldn't have wasted my time driving across town on a Saturday. Dude, I could be out riding now!"
really miss my last car... and though i could get away with roof bars on the new one, but noise, garage height, easy to (un)/install need to go back
If you care about your car or your bike, this is not the way to show it.
Short on then chaining the bike to the car in some way, how does this system prevent theft?

Junk.

true.
At least Fiat made an effort when releasing its modern 500 version.
