bicycle generator

Has anyone ever tried to build a generator that would fit inside the bottom bracket of a bicycle using the spindle thats attached to the cranks and pedals? seems it would work better than the ones that rub on the tires.

Is it illegal to use bicycle trailers?

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!

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 !

A few questions for recumbent bicycle makers

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.

Help: Mechanical Odometer

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.

Magic Freewheel & Bike Frame

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.

Preventing Kicked-in Bike Wheels?

After purchasing the toughest bike lock I could find, I got the wheels kicked in by a frustrated would-be thief who could only get through the plastic coating with whatever tool he was using. (he incidentally got all of the other bikes locked up outside my dorm.) The closest lockers are a 30 min walk away, and they only allow for a small, easily cut padlock. I have an uncharacteristically small dorm room, so racking it in my room isn't really plausible. Any ideas? Maybe a couple of spokes reinforced with steel bar, or a cheap homemade bike shed?

Help me reduce my carbon footprint and big fat gut!

So I'm trying to arrange a set up where every morning I pedal my bike, in a training stand, attached to a car alternator, attached to a deep cycle battery which will ultimately be feeding all those computer peripherals that I have scattered across my desk. No exercise, no DSL, etc. (And no, I don't do subsistence farming in my back yard (yet) so I know I'm not really doing much environmentally besides reminding myself how much energy all those littler peripherals suck.) Anyhow, I've seen numerous articles where people are easily getting 12-14 volts out of their alternator. At a level of effort that feels like 20 mph on level ground I'm getting maybe 3v. Any idea what I'm doing wrong?

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.

How to redirect Bicycle chain?

I'm working on a [secret] project that involves a recumbent bicycle. I'm going to have to use a long, tandem bike chain. The problem is, the pedals are going to be mounted at approximately a 32-43 degree angle to the rear axle, with an obstruction (me and my seat) in the way. Is there a way to some how redirect the chain, so that it would go under me? Thanks!

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?

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

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!

elliptical bike?

Has anyone ever heard of an elliptical bicycle? I came up with a design that would pedal using the walking motion of an elliptical trainer and you could stand up or sit down. I recently have seen a video from Maker faire and caught a glimpse of a bike with a similar design. Some minor differences included: The use of a chain ( I think that might give more room to walk/pedal opposed to my design with no chain), the pedaling is higher, and it looks more sturdy. This is helping me produce a better design. A glimpse at the other design is around 7:00 to 8:00 in this video. I hope someone has heard of it.

Remote control light for bicycle

Here's the scenario and idea. Scenario: MY friends and I have taken up biking, however sometimes we get a little far from each other. My concern is that if one of us blows a tire or something like a chain falls off happens, there is no way to alert whoever is in front to stop. I've tried screaming but only look like a fool to anyone's house we ride by lol. My solution. I would like to build a remote light kit. I would like to have box with a small button (box size hopefully no bigger than 2x2 in) that could send a signal to another box on my friends bike that has a light attached to it so when I press the button (on my box) the light in the box on his bike lights up (therefore signaling him to stop). Dilemma: I know nothing about remote control electronics, as far as I can figure I need some form of transmitter and receiver. Hopefully able to run off of a triple a battery or one of those CR2032 watch batteries. I would need it to be able to send the signal maybe 100 feet (but if it can go further that would be welcome) I'm hoping maybe someone has experience with such items and might be able to suggest something... ANY help would be greatly appreciated.

Bent Bike Frame

Yeah, so, my brother bought a mid-80s Schwinn World Sport. It's a nice bike. I spent about 10 hours overhauling every piece of that bike. Unfortunately, when I got it all put back together and test rode it, the bike had a nasty pull to the right. Bent Frame. He didn't check that when he bought it (didn't know anything about it, I daresay).  Anybody know anything about repairing a bent frame? The frame's tubes don't seem to be damaged or crimped or dented.  I'm thinking of using a car jack and some straps to straighten it out. Any thoughts?

I inherited a Currie E Bike conversion kit which included the rear wheel and drive motor assembly and battery pack/charger combo. It did not include the wiring harness or throttle.

Does anyone know enough about these to know the wiring layout or any other parts that are needed? I have a bike already to convert. I can solder and do most of my own bike repairs and some fabrication, so this doesn't appear above my usual skill level. Thanks in advance for any help. Jim
