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

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?

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.

Right, so I want to build a bicycle trailer that will carry a kayak and also is used for something else, but that's for an iBle, and not the point. As we all know, bicycles are considered vehicles in all 50 states. But, trailers that are pulled by motor vehicles have to have registration and tags. Is it so with bicycles? I don't want to break any laws, so if anyone has an answer, I'd appreciate it!

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.

My daughters bike has a grip shift for a rear derailleurs, shifting from from easier gears to harder is easy because the derailleur spring assists. when shifting the other way it gets progressively harder to pull the derailleur in. It gets to a point so that my daughter does not have the strength to shift after gear 3 has anyone got a solution, other than hand exercises for my daughter. Thank you

OK, here they canibalize bicycles. Usually all that they throw out are old frames and rims. So your mission, chould you decide to accept it is to find something more interesting to do with a discarded bike rim than making a crab net out of it. (ps. spokes and freewheels are included with most rims)

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 !

The frame of my bike is too short for me so my back seriously hurts especially up slopes. is it because the frame is too short or the handlebar is too low? if i reposition the saddle backwards, the cycling is a bit better but not a lot. next idea is: i have is to buy longer stem 2nd idea is to buy saddle support (pipe) that is bended backwards.

According to his profile, wautur is in the Netherlands, but there's no other info on this one, sadly. Skip to 1:30 to see the bike in action.

Okay, as the title says, i've got a few questions for anyone who's made a proper recumbent bicycle. First: in the way of moving the handlebars back, how do you attach a bicycle chain sprocket to the top of a fork tube? is it welded? or is it a special type of sprocket with a sort of crankshaft keyway (like engine crankshafts have keyed sprockets for their timing chains) this is obviously to relocate the handlebars further back or under the rider so that you can lean back (as most recumbents allow) Second: if you're to put a larger tire on the rear of your bike (for example, a small (50-500cc motorcycle) rear tire), how would you go about converting the chain link sizes. most motorcycle tires have a shorter link distance, and look like their links are sort of squashed together as opposed to bicycle chains. would you find a way to put a larger toothed sprocket on the rear tire or put a smaller toothed sprocket on one side of an intermediary and a larger toothed on the opposite side? If I have any more i'll post them, these are my pretty basic "burning questions" of recumbent making.
Posted by TheMadScientist 6 years ago | last reply 6 years ago
Why are there not more instructables about building homemade recumbent bicycles? I was only able to find 2 and one was not the type of recumbent bike I'm looking to build, the other had minimal pictures and text to describe the bike. I know more people have built/tried to build them so lets see some instructables about it!

I have a bicycle trailer that I use for groceries and such, and hope to use for extended bicycle trips. I would like to get or construct an odometer for the back of the trailer, to advertise how far I've traveled. I've looked around a lot, but have had difficulty finding an non-electric or large-display DIY odometers (ideally, I would like the numbers to be 2 to 3 inches tall, and would like to keep it below ten pounds). I would prefer it to be mechanical only, requiring no batteries or electrical power, but am willing to give on that point for the sake of simplicity of design, weight and cost. If you have any advice where I could find advice or instructions on how I might set something up, I'd greatly appreciate it.

The machine shop I work for had this "great" idea about 10 years ago. Wouldn't it be nice if you could pedal backwards on your bicycle and still go forward? It's like 2 things in one! Not as glamorous as it sounds. So I'm getting rid of some old parts to various "Super Gear" projects including the Magic Freewheel, an Aluminum bike frame, and if you really wanted them I an go dig out some of the old gears in storage too. Make an offer if you want something. We can ship UPS.
