Introduction: EASY PARTY BIKE

Ever want to listen to music while you bike, not using boring headphones? How about taking music to outdoor parties without having to lug a set of speakers around? This is a super-easy way to listen to music while you bike...

PLEASE: Post your ideas to add on to this in the comments section, for everybody else, and me, to do. There's never too much music or speakers to blast while biking!


What You Need:
A cheap mp3 player, it will be alot easier if it takes a disposable battery...
A bike
A ton of duct tape
An old speaker... I used a speaker from a broken amp
Some batteries, the bigger (D) the better
A speaker cable

NOTE: You're mp3 player might break, thats why the cheaper the better...

Step 2: WHAT TO DO

Alright, now let's say you have all those parts... The first thing to do is to cut one of the heads off your speaker cable. A headphone cable would work better because it is already separated. Make sure the wire will conduct electricity. My cable had 3 small copper wires, each coated in a finish that I had to sand off. The colors I had were red, blue, and copper. If you somehow end up with one like that, don't bother sanding off the copper one, you wont use it, and it may not have a coating if you do decide to modify this idea.

Now, take your speaker and connect the stripped wire to it, and plug the other end of the cable into a computer headphone jack. Switch the wires around to the opposite sides and see which sounds better. Once you have decided the better sounding way, solder or just tape them together.


Alright, now the fun part. I am not liable if you end up frying your mp3 player, but all I know is that mine did not die on me. Since I used a sandisk sansa e130, shown in step 1, it takes one AAA battery. That didn't seem to last long powering a small fender guitar amp speaker, so i figured this easy step out.

Let's say you have something like my mp3 player. It can take a AAA, AA, C, D, two of each, anything works as long as it takes that battery. If you have a rechargeable battery, I can't really help you, but maybe you got lucky and it takes an even voltage that you can make from a few batteries. Now, take the largest battery(s) you can find, as long as they are 1.5 volts, and depending on how many batteries your mp3 player takes, hook them up in parallel, or if you have one, just tape two wires to it, one on each side. I used a C battery because I had nothing bigger. Now, either solder or tape the other ends of the wire into the corrects part of the battery holder. (Positive on the battery goes where it normally would, only with wires) Make sure they are secure...

Step 4: TAPING

Nows the easy part... Tape everything! I taped my speaker to the bar across the bar, over the break lines. The brakes still worked, and so did the gear shifting. I would suggest taping it there because at least on my bike, the sound is pointed right at my head. I taped my mp3 player on the handle bars for easy aces, and the battery a little to the right (in the picture left, my camera reverses the images) so it could be changed easily.

Step 5: GOOD LUCK!

Haha alright good luck with this, it worked for me, hopefully you are as lucky as I am.

Like I said before, PLEASE POST IDEAS OR INSTRUCTIONS! I know there are better ideas out there, this is just a starter. Hopefully it will get people thinking about better ideas, and then those people can post their ideas here. If you make an instructable like this, post a link, or if you just have a cool idea please post it! Post some pics of my idea, or better yet your idea to give people ideas. Here is a list of other ideas that may inspire you:

stereo sound
better ways of mounting it
better amp
powered by the moving wheels
more speakers

    I would put some kind of cover over the cone of the speaker

    to protect it? good idea i think i'll end up doing that... if i end up riding through a few puddles or a lake again it might get wet! can exposure to sunlight also damage it? what materials do you think would be good to cover it with?

    i once mounted a set of 6x9 el cheapo's in the rear deck of a car, lots of sun, and trash flying around. so to protect them a little i glued some thin nylon i cut from a sleeping bag to the mounting gasket (the one that runs around the top of the cone next to the screw mounting holes). it vibrated nicly, and kept the sun/trash out of the cone.

    I mean something like speakers come with when they are new. some kind of screen or something so your speaker won't get torn up

    if you touch the copper wire to one of the regular wires you will get a BIG boost in sound quality

    It would better to have power going straight to the speaker like some subwoofers.

    Like instead of having the speaker being powered by the mp3player have the speaker being powered from another source as well.


    That wouldn't work. You would damage your speaker very quickly. You have the battery across the speaker, that is going to be constantly pushing out the cone and will create a short.

    haha thanks... im looking into taking the amp from a boombox... think that would work?
