Revolution turns your bike wheel into a rolling stamp. The stamps are 3D printed letters to clip on your wheel with a cable tie. Push the inking roll against the wheel to ink the letters and leave your message on the pavement. You can easily customize and 3D print all the parts you need.

The message can be customized with this thing:
The current design works on disk brakes and fixed geared bikes. We're currently developing solutions for caliper braking.
Or you know, don't use the back brake, only the front one...

Graffiti, cyclists - think no rules apply to them. Pffft.

Just going to the technical thing... Why just place it in the front wheel, leaving the back wheel free? This will probably solve the problem of the brakes, as most people use their back brakes, not their front ones! :)

Why would you want to do that? Imagine everybody that rides a bike leaving some sort of message and wet paint behind himself on the sidewalk.. that would be just terrible!! Forget illegal, but leaving "choose cycling" in paint on the sidewalk would, in fact turn me away from cycling.. Maybe its just me, but I don't like such political graffiti, somebody forcing his way of thinking to others.. Like cycling? Good for you, go cycling.

Replace the letters with some sort of "spikes" though, and you got yourself a good grip in the show..

Guys I think its a proof of concept calm down

with a water based inks you should be ok but check county and state laws

Great Idea. But it is illegal in most places. But they couldn't bust you at the beach. You wouldn't need ink! Or Burning Man...

Completely illegal here, for both bike safety and council graffiti laws. Who is the goose that picks the features?

This would prevent your brakes working correctly .... why would you do that?

not only that, but traction would be rubbish :/

You can use the breaks on the other wheel.

Good to see Thingiverse features ways to make graffiti.

Clever idea. Probably illegal in most public places in the US. If it were (as one commenter asserts) permissible under the doctrine of free speech to mark public streets and sidewalks with one's thoughts or advertisements you can bet that every street in every major city where this was permitted would be entirely covered. Look at how much a billboard costs in those markets and do the math. As for the impermanence argument, A quick Google search will reveal an article a few years old concerning a 6-year old girl in Brooklyn threatened with a $300 fine for a chalk drawing. Still I like the sentiment. Good luck.

If I see anyone doing this in my city, I will throw a stick in their wheel spokes.

Oh man, you gonna be busy on post-rainy days then.

Yeah, because physical assault is a rational reaction to them spreading the message "choose cycling" on the road?

the message is customizable.

Non-lethal force to stop the commission of a crime (vandalism) is not physical assualt.

I'm with you, Robert. It's considered Criminal Mischief here in Texas also. There's no defense to prosecution that the marks were "washable" or not...
Texas Penal Code: 28.03. CRIMINAL MISCHIEF. (3) he intentionally or knowingly makes markings,
including inscriptions, slogans, drawings, or paintings, on the
tangible property of the owner.
Of course I don't recommend defending public property against someone committing criminal mischief, unless it's your own property. And in Texas, someone can get killed for criminal mischief at night:
Sec. 9.42. DEADLY FORCE TO PROTECT PROPERTY. A person is justified in using deadly force against another to protect land or tangible, movable property:
A) to prevent the other's imminent commission of arson, burglary, robbery, aggravated robbery, theft during the nighttime, or criminal mischief during the nighttime

So if I punch you in the face because you littered, that's not assault? Unless you're a trained police officer (in which case you'd have the training to know better) you're not allowed to use force to enforce your interpretation of the law.
For example, in most locations, a little ink on the road, particularly writing a political statement, isn't "vandalism", because it's not doing any damage to the road, just writing a message in a public space. Which is, y'know, generally legal in the United States, since the Constitution protects freedom of speech. Heck, Businesses, ad campaigns, etc., paint messages on roads and sidewalks all the time, and it's legal even if it's not political speech, just advartising. It's only illegal to write messages if it breaks some specific law, such as being obscene, or libel, or if you deface something that's specifically protected, like painting over a street sign, or a work of art. In which case you still aren't allowed to use force to stop it, because the penalty for painting something is fine, or having to clean the paint off, not being physical assaulted.
So you're advocating physically assaulting someone for doing something that's legally and constitutionally protected. Instead, how about a civil discussion?

defacing property (public or private) is not legal and not covered by Constitutional protections.

Interestingly, none of that applies to a bike leaving ink marks on a road or sidewalk, since it's not a building. Perhaps that's why sidewalk art, etc., is so routine (and doesn't lead to people getting arrested or fined). And, of course, the dollar value of the "damage" of ink that washes away is $0...

I have no doubt about the intent to use permanent ink or paint. They even suggest that ink form a normal blotter works great. And as to the using water idea, great, but that is not what they are advocating...look at the inked parts on the picture.
By the way, you conveiently glossed over the whole "property" part.

Any way you can 3d print a thin clip that is inflated between tire bead and rim wall? That would eliminate the zip ties.Possible to place behind tube and create imprint with special thin tire?

How do you rear brake?? This is stupid..

Reading comprehension isn't your forte, is it?

Glow in the dark ink and ride during the day (on your own private road or parking lot, of course)

haha. Nice idea!
btw this also works a grip enhancement in ice and snow :)
just only use the zipties...

Do the zip ties that wear away and break off ever cause problems getting jammed in places they shouldn't be?

They actually make a product for car tires that is based on large zip ties and has traction blocks for winter.

nope. ive used zipties all winter for snow on road bike tires, helps a lot

Yeah I'm still looking for the best white paint. In the mean time, the black ink from inking pad works well on concrete...

hum? white paint ?

yep and have the stamp say i hate cops... make sure to drive by as many police stations you can :-P

Hold my beer
