It isn't hypothetical. It's ridiculously stupid.

The problem is to get the suction cups to have enough power you wouldn't be able to ride the bike. There are suction cups that can lift 10,000 pounds however.

not to mention being able to stay on the bike.

Clip pedals with a few hundred pounds of strength would take care of that.

well if you arrideing on a wall. how you going to stay up? i would think gravity would pull you down so youcouldt ride..

not going sideways. that would be impossible.

I wonder how it'd work in a completely dust-free perfectly flat environment like a white room.

Don't underestimate my strength. I've gone sideways on a bike many thousands of times on a half-pipe. It isn't as hard as you think.

Hi, my name is gravity and I don't let people ride their bikes at a 90* on a wall without falling.

please explain, seeing as suction cups work by creating a vacuum (F = 1atm*A). i guess if you made one big enough it would....

It wouldn't. You have to apply pressure to a suction cup before it will stick, when going upside-down there is no force to cause the suction cups to collapse. Ditto for riding sideways. though, if you had a loop you could potentially gain enough speed to go upside down, then stop and hang from your bike (and then wonder how to get it down) much like a roller coaster. That is, assuming the suction cups suck enough...

Physics fail.

Angular momentum.

We used them in moving. It says 1000 pounds, thought the limit was 10,000.

yeah, they're just big :)

....so bigger is better? :Q :eek:

suction cup roller blades of course!

Screw all you haters, I will try suction cups on a bike myself. I will try to get pics/video.

The main issue would involve the precision involved in choosing suction cups that operated near tolerance but still factored in the oscillating movements of the operator enough not to let go until the appropriate increase in force was realized.
