This is a large suction cup that can attach to flat, non-porous
surfaces like sheets of glass. Either it has a U-lock, cable lock,
chain lock, or similar built in, or it has a stout loop for one to
be locked around. In this way you can lock your bicycle up to
the window of a business that doesn't
have a bike rack.
Most businesses have tempered glass windows, which are
unlikely to break if a thief tugs on it. However, fear of having
their windows broken will incentivize the business to install a
bike rack. (There may need to be legislation banning
businesses from banning the use of these on their windows.)

Someone needs to do something. I'm not always able to find
something to lock up my bike to. I ride around looking for
some post or structure or whatever. It's crazy. |
|
| |
Is the suction cup provided by the cyclist or the store? |
|
| |
Also, what stops someone sliding a blade under the edge of
the suction cup to break the seal? |
|
| |
By the cyclist, I was envisioning. |
|
| |
I don't know. Is that a realistic vulnerability of a large
camlock suction cup? Perhaps the rigid outer cup could
extend all the way past the edge of the flexible cup and
press against the glass to exclude blades. |
|
| |
It occurs to me now that if the suction cup is a separate
device from the lock, it's going to need a built-in lock
mechanism still, to prevent unauthorized suction release.
(I doubt any discrete bike lock would be tight enough to
hold the cam lever in the 'suck' position.) |
|
| |
I dunno, [not]. I'm pretty sure that I could slip a long, thin
flexible blade between a very flat pane of glass and anything
you want to glom onto it. |

Have a tough metal mesh backed by water-saturated foam, covered in a hard metal outer shell. Apply to window, power on peltier-effect cooler. |
|
| |
Water rapidly freezes to glass, entraining the metal mesh. Ever tried scraping frozen rain off a windscreen ? |
|
| |
To release, reverse the current and the ice melts. |
|
| |
Runs off only four car batteries... |
|
| |
Then you just break the frozen glass, or walk 5 feet to the
nearest Starbucks and get a cup of hot water to splash on
it. |

More expensive than buying your own bike, shirley ? |
