Night Bike!

Night Bike!
Gas is too expensive and not ecofriendly, so I like to bike wherever I can... unfortunately that means a lot of biking back from work at night.  This always makes me a little nervous, how much can you trust drivers going 45 miles per hour right past you?  I mean, a little dinky bike light can only do so much.

After too many close calls to count, and a lot of weekend tv watching I was inspired by the Blackberry commercial,  As you can see, they had much more than a small flashing bike light to keep them safe, and those bikes certainly had some flair!  

After doing a little bit of research, I found that there were some super glow in the dark paint, better than your typical craft store stuff.  In fact it's called phosphorescent paint which can glow for up to 12 hours, is substantially brighter than simple glow in the dark paint, and only takes 10 minutes to charge up!  

I must say, after creating this bike I feel much safer riding in the dark, cars are able to spot me from quite a far distance.  I've even gotten a few compliments on the cool style of the bike! Safety and style... it's a win win!

So thus begins my instructable - a glowing bike that will not only amaze friends and onlookers, but be extremely safe for riding in the dark.    

UPDATED INFORMATION and TIPS and RESPONSES TO COMMON QUESTIONS:
- I bought my paint at glonation and it worked fairly well.  A better choice (for brighter glow) may be gloinc as they advertise their paint is 3x brighter than their competitors.  However, it is pricier than glonation.  You could also do a little google search on super phosphorescent paint and you will find a few other places to purchase the paint.  You can't buy it in a typical craft store (at least to my knowledge).

-The paint is NOT radioactive... so you don't have to worry about that

-We used 8 ounces total, 4 for the frame and 4 for the wheels.  We had to put on many layers since it is hard to get even coverage with a paintbrush.  There is not a spray glow phosphorescent paint on the market yet, it is being developed soon hopefully.  The paint is creamy, so doesn't really work for an airbrush.  

-Be careful when you purchase the paint and READ the advertising.  For instance from glonation it states that orange only glows for 15minutes while is says that green (though dims) glows for 12 hours.  Gloinc states that their green glows for 24hours, gloinc also has some information on the brightness on each glow.

-See last page of this instructable for some really cool black light LED's that would fit on the bike inconspicuously and give it an even brighter and longer glow!

Step 1Phosphorescent Paint

Phosphorescent Paint
Now I want you to know that when I say this bike glows... it REALLY glows.  Back when I was a youngster and was fascinated by glow in the dark paint, I was always disappointed by how dull and short lived the glow was.  The typical craft store glow paint is zinc-sulfide based in an acrylic medium, if it is colored pigments are used.  The problem with using pigments is that these colors absorb most of the light, and thus the glow isn't as bright.

Instead, phosphorescent paint (used for this bike) is strontium based and glows 10 times longer and brighter. Impressive!  

The paint works only after it is exposed to an energy source, like the sun or black lights (these work really well) or regular lights.  The paint absorbs the light energy and the little electrons get excited and jump up a few energy levels, sort of like climbing a few steps on a ladder.  This is not a stable state for the electron  (eventually you have to come down the ladder) and once it falls back down to its "ground state" it emits light, in the color of your paint.  It turns out that strontium aluminate is more efficient and better at this than craft store glow paint.

Love this project!
Will be making one and posting it on youtube, but it will take a few months for me.
Btw, I am ROBOCOP603 on youtube as well.

Just did a new bike, "White" painted it w/glopaint, the good stuff (3-4 coats). Looks like glue and streaks of green from glow, glows great "But" you can see brush strokes at night when close..Also, goes on rough like sandpaper...

I guess I should have used a spray gun, "Will it change the consistency and NOT be so rough, white looks white but up close you can see the glue type consistency and little green color as mentioned..

Anyone done one with a spray gun, does it come out better?


Jan 19, 2012. 5:16 PMSargentPepper says:
Cool! me too! I'd like to know if anyone did it with a spray gun as well...
Jan 19, 2012. 5:16 PMSargentPepper says:
I just did a bike too! Like ask tom... mine turned out great! It is super cool. I tried to take a picture of mine to post.... but it did not look nearly as good from the camera view as it did in person. And it did glow like 4 hours for me... not that I bike that long anyway.

So glad you posted this instructable! Congrats on winning... you deserve it!

The EXIF creation dates of your photos taken after different amounts of discharge time don't match up with how much time you say elapsed. I prepended the filenames with the quoted elapsed time and used exiftool to look at the creation dates. It shows the files were only created minutes apart not hours. The EXIF data also says you used a Canon PowerShot S5 IS, which is capable of taking movies. When I asked you to post a video in an earlier comment you replied "My camera doesn't have video."

Can you explain these discrepancies?

Congratulations on winning the "Make it Glow" Contest. I voted for you and suspected you'd win. - Great looking project!

THANK YOU!!!!! My daughter wants a night bike so badly thanks to that Blackberry commercial - I'll make her one!! :)

Curious, though - how long does the glow seem to last for?
Jan 18, 2012. 11:00 AMchuckr44 says:
The glow lasts about 8 hrs each time you charge it with light, but it depends on how far away you are. It should be clearly visible for at least 4 hours but gets more dim as time goes on.

To reuse, simply expose it to a bright light, or a black light for 5 minutes.
Jan 5, 2012. 10:43 AMicanhaszombie says:
On the first page or so of the 'ible the author mentions that the glow can last up to 12 hours on a full charge :)
Jan 9, 2012. 7:02 PMGreyP. says:
so it only lasts 12 hours? or 12 hours after the sun or a type of light shines on it?
Jan 11, 2012. 3:53 AMtamurlane6 says:
I'm pretty sure it lasts 12 hrs per "charge" I think it would get really expensive if you had to paint it every 12 hrs.
Jan 5, 2012. 11:12 AMamandat0913 says:
Gah - thank you. That's what I get for skimming. :/
Jan 17, 2012. 3:11 PMmsrun1 says:
Hey what do u mix the glow powder with? (from glonation)
Jan 18, 2012. 10:56 AMchuckr44 says:
Try mixing it with clear nail polish. That's what I do. Nail polish is hard and durable, but make sure you do surface prep correctly.

That might be fun for a "beater bike", but I wouldn't brush-paint any bike worth much money. Also, do not forget any legally required reflectors or lights. Just because your bike "glows", does not mean it is very reflective, and even if the whole bike lights up under headlights like a DOT sign, it still might not be sufficient to pass your laws, and might not be that attention-getting from behind (bikes are narrow).

you guys should check out bike after dark.com... i got a pair of their lights for my bike and everyone who has seen them wants to know how they can get some for their bikes!
Jan 10, 2012. 10:36 AMLo-couk says:
Glow in the dark paint is best charged with UV Black lights, they are fairly expensive but it'll be worth it as you'll only need 1 or 2.
I've got to find a car spray shop to do my car now :D

I've got a question about the pain. Is the paint itself clear and it just glows various colours? I've got a very nice paint job on my bike that I don't want to paint over (kinda sentimental, I am) and I want to make sure that I can keep it while still being as safe as possible.
Jan 5, 2012. 3:30 PMextrordinary1 says:
why can't we use an air brush to paint it? Beats waiting for the airosol to come out. Exactly where did u find this paint you display?
Jan 9, 2012. 1:02 AMdread says:
this page discusses air brushing (but for the other supposedly brighter product from glowinc): http://glowinc.com/glow-in-the-dark/glow-in-the-dark-painting.aspx
Jan 8, 2012. 8:00 AMSpoonmeister says:
You could, theoretically, use the paint in an airbrush as "normal" airbrush paints have thinners added to get them fluid enough. HOWEVER, you'd have to check whether or not the thinners would adversely affect the structure or the paint or its glowiness. If you have an airbrush already and you get some paint it may be worth trying it on a small piece of scrap material and analyse the results with & without thinning & spraying - I for one would be interested in the results.
Feb 13, 2012. 1:04 PMjolshefsky says:
One of the problems with airbrushing that I read on the glow paint sites is that the way the paint is brighter is that it has particles that are pretty large — too large for an airbrush. If you use the finer particles that will not clog an airbrush, the glow is not as bright.
Jan 5, 2012. 3:17 PMSporkyRat says:
I have a hybrid cruiser so weight's not really a problem and as long as it doesn't hide the paint color there now I'll be perfectly happy.

Thanks so much for all the information!

My bike is blue, it has shocks front and rear. I was wondering if anyone tried just painting with the phosphorescent paint over the blue paint to see how it looked? It might be a waste of time but I might give it a try.
Jan 5, 2012. 9:56 AMDeusXMachina says:
You should charge it with a fluorescent blacklight. They have CFL ones that fit regular lamps for $4 at the home improvement store. It's the lower wavelength light that does most of the heavy lifting in energizing phosphors. It can charge the paint to quite a bright intensity in a matter of seconds, and you may even get a brighter glow in 10 minutes than with incandescent bulbs.
Jan 5, 2012. 10:57 AMCodySteed says:
Buy two battery powered blacklights. they are about 6 inches long. You can have them attached on the bottom flat of the handlebars and they would not only "charge" the bike, but also add a lot of glow to them i think.
Jan 7, 2012. 11:02 AMDeusXMachina says:
Yeah! That would also work really well.
Jan 7, 2012. 12:46 PMAdvar says:
"Brilliant!"
;))
Jan 7, 2012. 12:28 PMsnotty says:
LOVE it! I suppose this would be nice in conjunction with the reflective bike using glass spheres.
Jan 7, 2012. 8:32 AMchakra says:
awesome Instructable!!
this will surely make those doozy drivers to open their eyes & notice!!
