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.

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?

With my customization of my bike, I just have to have a speedometer. But, I haven't found a single place on the Internet showing how to make one, just how to buy one.I know that speed = distance/time. I was thinking, since this is going on my bike, I could measure the circumference of the rim and hook up a circuit that would have a something (motion detector?) on the front brakes and another something on the rim, the one on the brakes counting the number of RPMs. I could have it hooked up to a timer, and it would have a digital read-out, which would calculate the speed, that updates every certain number of RPMs.Has anyone ever built a speedometer, or if not, do you think something like that would work?Thanks!

I want ot make a moped, but theres NO WAY im buying those expensive mofo, kits for $200 when i could just as easily build one, i figure all it needs is a motor of 50cc or less(state law says)i figure, a weed wacker is usually ranged from 20CC to 50cc ill try that but so far the most i have found is 32cc, i also figure it will require a chain and a drive train which i can fabricate from another bike. i hear chainsaws are very powerful like 40CC + range which sounds good but im just not sure about de-constructing one of those, if anybody has had any experience with motor bicycle please help

I ride in the San Jose Bike Party. One of the things that I like is the music. People with all sorts of boom boxes, dj systems, and lighting mounted all over their bikes or trailers. I would like to build something like that and I am checking out the many interesting projects listed here. I am wondering though, is it possible to speed the music up or down to match the bike speed, maybe with a magnet on the wheel and a sensor on the frame? I don't know if it would be a good idea, but the thought of a dirge when we are slow and chipmunks when we are fast is just funny to me.

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

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

I've seen old pictures of the contraptions at work but need detailed plans on the gearing, inside of the barrel, and the basin in which it sits. I volunteer at a site where we don't have the standard washer/dryer hookups and if I could get and make this, it would save us a couple of hundred dollars in laundry bills. Also plans for a decent water filter to separate the dirty, soapy junk in the water so I could send the filtered water down the storm drain would be great.

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!

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!

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

Question by huot 9 years ago | last reply 3 years ago
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!

Right now I have a 12 volt 5 amp Werker lead acid battery powering lights, cell chargers, gps, and a few other gadgets. When I go on long trips I take the batter charger with me to charge the battery with a wall charger. The wall charger is heavy and unnecessary if i could find a way to harness the power I generate when I pedal. i have seen plenty of generators which generate electricity by physically touching a dynamo to the tire but there must be a way to do it inductively, with no friction. What if I covered the wheel with hard drive magnets and ran them all past a coil on the frame? I know magnets going past coils will make electricity but not about rectifiers and capacitors and etc. How could I make this? Thank you
Question by Noblenutria 9 years ago | last reply 9 years ago
I was told that I should make a forum topic out of this. So here it is:Here is a link to my upublished instructable:Magnetically Propelled BicycleI came up with this two weeks ago while I was day dreaming about levitation and magnets.The idea is that one stationary magnet set up on the middle of a bicycle negative facing front, can push two magnets bolted together, each facing negative, with an axle running through them and wheels on opposite sides. So when the stationary magnet'ss power is increased, the two magnets in front will be pushed, thus rotating the axle where the wheels are attached, adn obviously the wheels are turned.I say "when the power is increased" because hopefully an electro magnet can be used. I am not sure, but I think an electromagnet can be hooked up to a car battery, and then with some control device, more electricity can be sent to the magnet, possibly increasing the power ( I don't know much about this stuff so help me out here.Look at the schematics for all of the anatomy.I have not figured the turning system out completely, in the intro picture you may see that the turning wheel is connected to the rear by a bar ( In the way I believe it may work there will be two bars side by side, I can't really explain it yet). That is how I plan the turning to the controlled.If you have any ideas for this project, add a comment. I have not made this yet and am still creating it.Please, do not steal my idea, I am only 14 and just started inventing. I have no idea how the patenting system works and I do not have the money for it.I would also like to know more about electromagnets, how they work and where to buy them. I saw one site where the best electromagnet can "pull" like 1300 pounds, so this thing should go pretty fast if it is built properly. I reallly want to know if it is possible for electromagnets to push, that is the whole Idea for this. But if they can't, I've already drawn a simple schematic for pulling the wheels which is on the next page.I also want to add that the stationary magnet cannot be level with the rotating magnets, it will have to be a little above, and if you add a mechanism where the stationary magnet can move up and down, you can control the bike forwards and backwards.Hopefully, no one has a patent on this ( I've searched and haven't found one). And hopefully this will replace fossil fuel vehicles, although I doubt the government will allow that. THE WHEELS/ROTATING MAGNET IS NOT ATTACHED TO THE BICYCLE. IT IS ONLY CONNECTED BY AN AXLE RUNNING THROUGH IT. JUST LIKE A BICYCLE OR A CAR. Here is a link to what I was sorta thinking:Here Just turn it horizontally and add wheels to the ends. The gyro- thingy is like the rotating magnet and the base is like the stationary magnet.

I will try and get some photos but alas, I have only a web camera. We had a German guy live with us for a 14 months and he left me his bicycle, and for NZ$50 which was great it has 30 gears, he left us 2 months ago. I picked up a pram and a little thing like a hamper trolley with no basket on it from a rubbish pile during an inorganic rubbish collection and the pram had single hooked handles. I picked up some galvanized tubing from a rubbish bin...I asked the worksite foreman could I look through the rubbish bin 9 moonths ago...I think thieves dump stuff in worksite rubbish bins...um, I came to Instructibles after browsing computer forums for 4 years...yay, I am here...and I saw the articles about the bicycle trailers and realized I had a bicycle. I can add so put 2 and 2 together and came up with 1 1/2 so went to work and built a bicycle trailer. It took me 2 hours maybe 3 and it works great. I am so pleased, I have an idea to offer computer and computer peripherial cleaning as a local service and the bicycle trailer may come in hady for pickups and deliverys and I have already practiced using the trailer to transport repaired LCD monitors to the PostShop after I repaired them, and how lucky I was for to get them repaired, phew...I am so happy...and...Jesus loves me...or from what I remember of Him he loves me...

Tetranitrate's Japanese adventures are not the only exciting happenings in the region: on Friday (08/08/08), the 2008 Summer Olympics began in Beijing, China.Despite concerns about air quality for the games and preparations, these games showcase some very cool designs, cultural aspects, and other miscellany that we would otherwise not have seen. The two featured buildings to check out are the National Aquatics Center and the National Stadium, more commonly referred to as the Water Cube and the Bird's Nest. They are very interesting buildings, and architecturally stunning as well.For the bike enthusiasts out there, Make Magazine posted this album of bicycles in Beijing.And some digital enhancement: China apparently wasn't happy with the fireworks display, so they added some CGI fireworks for television viewers.

The couple making the film are fantastic people I'm pleased to count among my friends, and I'm completely amazed at the level of personal commitment they've demonstrated in making this documentary. Here is a quote from their Kickstarter page. Within Reach Movie documents a pedal-powered search for a place to call home in a sustainable community. Mandy and Ryan traded in their house and cars for a tent and bicycles to "bike-pack" 6,500 around the USA to visit 100 sustainable communities, looking around as they looked within. This journey and film has answers to the questions many of us are wondering: "Is it possible for all of us to live in a sustainable way?”, “what would the world look like if each of us simply did what we loved?” After circling the country, and talking with over 20,000 people they have found that not only is it possible but this is already underway.

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.
