I know they did some nice looking bikes but I don't think there were any folding racing bikes in the lineup.sticky said:Chris_D said:I wish there were such a thing as a foldup full carbon racing bike. I'd take mine absolutely everywhere!Smartbear said:I came up with a different solution

Didn"t BMW do something like that few years ago ???
What's the worst that could happen? (bike rack)

I"ll have a sniff around, I was in BMW shop in Berlin ca 7 years ago they had some expensive bikes in there, folding, alu and other bits as well. It was aimed at "city" people and the shop was/is on Kurfurstendamm, money and more money
Thanks DM!
I wouldn't be using it if I had any doubts. Two lads in work have these, one has the two bike version and has been using it for two years. Never have any of the vacuum cups lost suction. They are both 1st class engineers, best in their respective fields. If they're happy, I'm happy.
Chris - on your point about monitoring suction levels: Each suction cup has a visual indicator. When you install, the pump lever disappears once the required level of suction is achieved. If this drops below the threshold level the lever pops out - it has a bright white band around it making it easy to spot. Essentially an early warning system.

Sorry to be harsh.. It wasn't intended as a slight of any kind, not my style.
I understand these inventions are subjected to rigorous testing prior to market release. I'd assume they've created the 'system' to take loads based on leverage under g force and so on. I'm sure every possible scenario has been thought of and the product is working well within the limits it's capable of..
I'm not an engineer, my main interest is creating music, though my business at present is within the construction industry. I'm always looking at the risk factors, and removing them completely or minimizing them to an acceptable level. A chain is only as strong as it's weakest link. I'd never use one of these because I see the glass as the weakest link, (and it looks silly
). The rear glass is not designed in any way to bear an additional load. It's designed to be a rear window of a car. The designers would have looked into the specs of the glass 10kg isn't a lot of weight but you've only got to hit a low drain cover or pot hole and the transfer of weight could well crack the glass and a whole new ball game kicks off. Then again the other suction cups would hopefully hold out. So probably no more than a few quid to replace the window.Being an engineer the 'figures' and 'stats' are enough to put your mind at rest. Me, my mind would always be thinking, is the window gonna hold out? Tbh I've found this thread entertaining. I'd never heard of or seen a bike rack on a sports car and it makes me chuckle, nearly as much as a baby seat in a roadster
. Live and let live. Whatever you buy, enjoy yourself 
the roadster isn't the car of choice for lugging bikes about but i have done it: I just stuck mine in the boot (large frame & so is the bike :? ). I put some pipe lagging around the frame to stop any damage occurring in transit.
it's less faff then putting on the cycle carrier tbh
you don't have to worry about leaving the car parked up with a bike on display
and no issues about watching your speed, well not with regard to carrying a bike anyway...
- wheels off
handlebars off
forks out
seat post out (mark the seat post for easy height adjustment (making tape, dab of paint etc)

First post here, so that means I have zero credibility, but I have a Seasucker rack and it's been amazing. The beauty in it is the flexibility of the rack. I've used it on my e46 m3, i3, alfa spiders, audi s6, and a defender. To buy racks for all of those cars would probably be thousands, and they wouldnt be half as good. There are two problems with this rack. First is that you have to take it off every time you ride. As it takes 5 seconds to remove, and about 45 to put back on, this isn't a big deal. The other is when it's cold, its sometimes hard to start suction.
If you experience this rack first hand, you will know that it's not going to fly off... It just isn't haha. One suction cup could easily hold a bike by itself (you could literally hang off of one and do pull ups on it). My rack as 5. I'm not trying to say it's the best thing since sliced bread, but if you think it's kind of neat, don't listen to the folks saying that it wont work or they wouldn't trust it. Not that their opinions don't mean anything, they just happen to be wrong in this instance.
I did 100-120 mph for 50 miles with my mtn bike on the roof of my m3. It was just as secure when I arrived as when I left. This of course was on a closed racing track..... Video for doubters that this rack is stable at those speeds....

Now I just need to buy a z4 coupe so I can use it on that next!!

Quite tempted by one of these I must say. The saris bones is about half the price though, but a bit of a faff I think having seen my mates one briefly (but I guess they both are really).
Any further reports OP?
Seems to stay on well enough an f-type, plus my bike only weighs about 6kg so it's not got a lot to keep hold of!

Hi TomK
First time took quite a while as I experimented with all the possible locations to mount it. The channel down the center of the Coupe roof limits the options but still plenty to play with. Now that I'm happy with where to put it, I can get from everything off to rack on and bike attached in less than 5 mins. Removing takes literally 30 seconds.
Used it three times so far. Very stable, very useful and I'm sure the flexibility to transfer to any car will come in handy.

Was thinking of going to the forest of dean soon for some proper biking.
It was fine on the previous roadster, e46 and citroens, not sure that the glass on the coupe would survive a trip with a bike or two, opinions?
might have to get the seasucker talon instead, as I'd prefer to keep it out of the boot as the dog won't appreciate that!

It will be fine as long as the surfaces are clean and the suckers aren't scratched. I used to film with some quite large rigs at some rather high speeds and never had a problem. On one trip around Europe I attached 3 cameras on the outside of a Lamborghini Diablo VT in very high temperatures. I wasn't going to be around to monitor them which made me nervous so i gave them instructions that they should be taken off when not in use and to check them regularly especially if hooning on the Autostrada. I saw the drivers that evening to retrieve my kit when they told me that the suction mounts had been on all day and they came very close to the cars top speed!!!!
I'll try to dig out a larger piccie, this one has a tripod on the roof, hooning through Cheddar Gorge.
Yet one is not allowed to fit a GoPro on a race car using the suckers as you know Dave :roll:
Yup, although roll cages at least make fitting much easier.
