Skeleton Bicycle

This skeleton bicycle by Jud Turner looks like the result of an archaeological dig from TRON world. OK, it's not meant to be ridden, but quite bizarre and fun on its own. Link via gizmodo

Bicycle Names

I name my bikes, usually for something wrong with them. Rusty, well, obvious. Lefty, it pulls to the left. Tiny, well, it's tiny. Some have more thoughtful names, like Phoenix, a bike I found in a ditch that was apparently thrown from a moving pickup. The fourth definition of the word Phoenix at this dictionary is a person or thing that has become renewed or restored after suffering calamity or apparent annihilation. Do you name your bikes?

Bicycle Mudguard

Hello there, people. First post here, been a member for a long time but only used to read instructables, but now im in need of help with a project. Im making a mudguard for my bicycle and im using a plastic folder. I know it sounds a little strange, but ive seen a lot of tutorials for mudguards made from some type of plastic, soft or hard. For example the ones made from a plastic cutting board. The first photo is of the folder and my question to you guys is, how do i make creases on the folder like the ones shown in picture 2. creases that help you fold the folder in those certain places.

Cardboard Bicycle

At the moment, it's just a design student's prototype, but I think this ridable cardboard bike has real legs, er, wheels.Built from a single sheet of industrial-strength hexacomb card, the frame should cost as little as 3GBP ($6), and the tiny proportion of metal parts means the bike has a projected selling price of 15GBP (about $30). For that, you get a bike that will survive about 6 months of daily commuting, or a lifetime of the kind of riding most people do.The designer, 21 year-old Phil Bridge, predicts the design will cut bike crime by simply being too cheap to be worth pinching (currently, a bike is stolen and abandoned every 71 seconds in the UK). It also provides an opportunity for sponsorship:"The idea was that it would be a sponsorship from a company who would produce these and get some advertising it. And once you've used it, you'd return it they'd give you another one, they'd take all the metal components out and put them into a new frame and the old frame would go back to the manufacturer."BBC Manchester articleBBC South Yorkshire article

Bicycle security!

Hey hey, so the other day i came up with a way that i thought might work well for a bicycle security...thing. anyways, since just about all bikes are made of metal, except the carbon ones, and metal conducts electricity, what if you had some way of making your bike, electrically charged? i guess (i dont know all the proper words heh) so if a person comes up to your bike and wants to take it, at some point in the process of taking your bike, he would come in contact with some metal part and get shocked. i thought if you made it properly, and made the shock strong enough, it would be a great way to keep your bike safe...cause i know if i went to take someones bike, and all of a sudden i get zapped all of a sudden every time i touch the bike, i would not want that bike! i figured you'd need some batteries with enough voltage to give him a good shock, enough to make him not want to take the bike, but not so much that you would kill him...that obviously would not be good.  but i'd imagine that more powerful batteries might be to big, and not fit anywhere on your bike. i thought that maybe you could hide everything in the seat tube after you take the seat post out, and maybe have a hidden switch somewhere on the bike so you could turn it off. im sure there's more issues i havent thought over, just an idea, and im far from an electrical expert, so i dont know how rubber shoes might ground the person, or how you would go about wiring it, and other stuff like that. i just wanted to see what some people here thought about it, and if it is even possible for me to do

Million Dollar Bicycle

For a million dollars you can get a bike with the lowest air resistance in the world and hopefully get a better shot at the Olympics. That's what bike manufacturer Koga is claiming for this custom ride designed for Dutch rider Theo Bos. Oddly enough, they make the claim that since it has only one speed and no brakes it is one of the most difficult bikes to ride. Whatever. That style of bike is called a track bike and if you're in a city you've likely seen people riding them around. It's not that tough. Link

Even though having a locking mechanism on a bike itself is a dumb idea I'd just like it for kicks. Y'know, after I've chained up my bike somewhere outside a store, turn around and "lock" it like a car as I'm walking away. Seems possible, but I just don't know how to go about this. Anyone have any ideas? Thanks for your time and effort!

Bicycle iPod dock

So here's my idea: I'm restoring an old bike and there's a spot for a fake gas tank to go. I will build this tank, but one side will open up and hold within it an iPod dock. At least, I'd like it to.  I'm thinking of using the pedals as a dynamo crank which would power the iPod and play music through speakers mounted on the handlebars. I've been doing a lot of research and it seems possible, however, I've not done something like this before and I was wondering if anyone would have any pointers on how to make this work well. P.S. A separate USB port would be cool as well, so that a phone could be charged while riding the bike.  Thanks for your suggestions!

Removing Bicycle Decals

Does anyone know of a good way to remove the decals from a bicycle, specifically a Mongoose Montana? On the Interweb, a lot of people say you can, but just as many others say that doing so will ruin the paint and mess up the clearcoat that is applied over the decals. Is there a way to tell if my bike has a clearcoat above the decals? If I can remove them, would heating them with a hairdryer aid the removal process? And the sticky residue - what's the best thing to get rid of it? Lighter fluid? Thanks!

re-spoke bicycle wheels

When I was much younger, I re-spoked two bicycle wheels off-center and put them on a bicycle for a parade. I don't recall how I did this except it wa s an article in pop. mech. or pop. science magazine, or similar mag. I do remember that I used 24" wheels on a 26" frame and that they must have been less than 2" off-center to fit the frame. It was fairly easy to ride at slow speeds, but terribly hard to go fast, as it would tend to throw you off. It was a lot of fun, though. I hope someone can tell me how to build one of these again. Thank you for any and all help !

Weed Whacker-Powered Bicycle

This is a bike I built a year ago. It uses a 30.5cc (about 1.5hp) weed whacker engine for propulsion. A version of the same thing was on Instructables, and that's what partially inspired me to make this. ;) The engine mounts are made out of wood, because I still have not learned to weld, but they hold up just fine. The engine is an ten-year-old Echo weed whacker. It has 10,000 max RPMs. The bike peg attached is 2" in diameter and gives about 25mph top speed. There is no clutch! The one that came with the engine was way too flimsy for a vehicle like this so I took it out. Saved a lot of space, too. For the throttle, I disconnected the back brake line and connected it to the engine. The front brakes are still intact, and you can turn the engine off to slow the vehicle as well. I added the extra heatsink to the engine to help keep it cooler, as it was never meant for this kind of exertion. It gets as hot as the engine, so I guess it conducts the heat away pretty effectively. There is a 10-LED bargraph to show the engine temperature. It uses an LM3914, an op-amp, and a thermistor. There is also a 555 to drive a buzzer when it gets too hot. The bike has head and taillights that are both driven from a joule thief. They are not very bright; they are more for being seen than to see. Here's a youtube video, taken almost a year ago: http://www.youtube.com/watch?v=bdySFqmK0Fw Some more photos and a little more information: http://forums.modretro.com/viewtopic.php?f=3&t;=656 Comments/criticisms? :)

Air ride bicycle suspension

So i've been interested in pneumatis for quite some time and recently I came across a small air cylinder (6 inch travel), 12 volt air compressor, 12 volt valve, and misc fittings. I got really excited and without thinking twice I grabbed tools and started hacking up my old beach cruiser (it was quite a mess anyway after 3 trips to burningman). So this is the outcome... I can control the up/down with a momentary on switch out back. Now just looking at this mess its easy to see that well i obviously can't weld. Never tried... Anyway it rides really sloppy as you can imagine, much like an old Lincoln with the shocks blown out, but it is so much fun! Now i pose the question to you community members, how would you have done this different? Looking forward to your responses!

diy elec bike assist

I guess I need to explain that I'm an old guy with a bad ticker. I also have some big time balance issues. I needed to get a little more active and work on my balance, so I bought a bike. The bike is about a million year old cruiser, so I had some work to do before I even took off on it. I cleaned and repacked everything. Then I switched out some parts to make it more comfortable. I replaced the sprocket drive set on the 26 inch bike with one from a 20 inch to make the peddles easier for me to reach. I also used the smaller drive sprocket. That might not have been such a good idea as I have to peddle more to get the same distance. I had intended from the start to install a helper motor so the pedal thing isnt really a big deal. I designed it this way. Motor: 24volt 250 watts from a kids scooter toy. drive: friction with a wheel that sits on the rear tire. Now the motor and mount I have worked out just fine. I'm waiting for everything to arrive so I can begin work. My question is about the power source. I really do not want the power source to ever run the bike. I simply want it to assist me climbing hills. I dont want to run out of oxygen (fuel) as is happening now. So this is my planned power set up, please tell me any flaws you see in it. One twelve volt battery 12ah complete with momentary on off switch. Push the button when I need a little assist climbing a slight grade. A completely secondary battery probably 7ah with its own momentary switch just to kick in on top of the first battery. When both are on, It should make a 24volt system for steeper inclines for just a few minutes at a time. What problems do you foresee. Any advice would be helpful. Did I mention I like to tinker with stuff. I found over the years when you buy something you learn to write a check. When you build something you learn lessons that are transferable to all problem solving. And my wife made sure I knew how to write a check early on.

I'm trying to build a bicycle cargo trailer. I was talking with a guy at my local hardware store about what I could use for a wheel base. He found a used Hitchhiker child's bicycle seat attachment frame and sold it to me for cheap. He said it was a child carrier, but on closer inspection I've found that it's just an attachment that adds an extra seat to your bike for a child to sit on. From looking at it I can't tell how I could fit the components of a cargo trailer on it and I can't find instructions for how to use it on Instructables.  Any ideas? Thanks a lot!

I think I'm being discriminated against because of my bicycle. What should I do?

At our school, they let you drive your car around the parking lot at lunch. Well, I ride my bike. So I ride around just like all the cars do, not bothering anyone, and they keep telling me to park it or leave. They never do this to the cars. They already discriminate against skaters (roller skates, skateboard), and scooterists(is that a word?). They put up a sign that says No skateboarding, no rollerskating, or riding scooters on campus. Well, that worked fine, people rode the afformentioned vehicles up to the campus, stopped, and carry them through, until the school staff started to grab the vehicles directly from their arms (I rode a skateboard once on a Friday, my first skateboard, just got it the night before, I think. I had just learned to skate, was carrying it, they snatched it, and hurt my arm with the griptape. They wouldn't give it back, so I protested after school. They kicked me out of the buiding, and I never got it back until Monday). Now it seems they are starting with bikes. They even took my bike once and put it where everybody in the school could do whatever they wanted with it. If they don't allow bikes at school, then I will have to quit, because I have no other transportation. What should I do?
