Wire from bottle dynamo generator touches side of bulb. Bottom of bulb touches the wire plate, which grounds it to the bike frame. This bulb is dark because it's burnt out, by the way.
Vintage bike lighting system from Germany. This is how the wire from the generator touches the bulb. Note it only touches the side of the bulb, not the bottom. This bulb is burnt out, by the way.
what type of current comes out of a bicycle light generator? the kind that run on the tire.....?

is it AC or DC , and how can I determine which one it is?
I believe it is DC.

Why does it become more difficult to pedal a bicycle-powered generator as the load increases?
Feb 07, 7492 by lugnut87 | Posted in Engineering
A bicycle-powered generator is hooked up to a light bulb. The rider pedals the bike, lighting the bulb. A second bulb is added to the circuit, and it becomes harder to pedal. Why does this happen as opposed to having to pedal the bike faster?
i'm no expert here, but i would guess that if you increase the power of one bulb that would be true (increases speed), but adding quantity instead increases the difficulty.

Will the bicycle be easier to pedal when the light is on or off? Explain.?

Some bicycles have lights that are powered by a generator connected to one of the wheels. Will the bicycle be easier to pedal when the light is on or off? Explain.
How do I build a bicycle generator for use with LED lights (I saw one used as an aide project for India)?

I would like to reduce my use of electricity by trying to go to solar power but I have limited resources (cash and knowledge). I would need free plans and instructions on how to build and simple procedures for maintenance, care, and use of the system.
You need a dynamo it has a tiny wheel inside which touches the wheel and when the wheel rotates the dynamo's wheel rotates.
The wheel is connected to copper coils which gets charged and produces electricity from the friction. The electricity

Bicycle powered electric generator?
Jan 11, 2010 by Daniel | Posted in Green Living
I live in the central U.S and as you can imagine we get tornado's and most of the time they are not that awful like you see in the movies. However, they have been known to knock out power for a while. Last time this happened I had no power for 2 weeks.
I think your best chance of having some backup power from a bicycle generator is to setup a bank of 12 volts batteries connected together and charge them on a daily basis using a bicycle generator setup.

Cheap human-powered generator brings light to East Africa

Features the work of Nuru Light , a Canadian company that’s designed an affordable lighting system for tasks we Americans take for granted after dark, such as reading and cooking. The Nuru Light in small, efficient, bright, and rechargeable; users can attach the LED-based unit to a headband, neck strap, or a wall mount. It’s also modular: multiple lights can be hooked together to create brighter light for owners. Nuru Light + Pedal-Powered Generator = Business Opportunity
The lighting unit in itself may not sound particularly remarkable (though people in Rwanda, the first company in which the company is operating, may beg to differ). What struck me was the model by which founder Sameer Hajee and his team chose to distribute the lights. Rather than centralized sales and distribution, Nuru Light figured “franchising” made more sense for getting their product out widely… and also provided another means for the company to empower Rwandan citizens. So, for $250 Canadian (provided through a micro loan), an entrepreneur can purchase not only fifty of the lights, but also a pedal-powered generator . The franchisees can sell or lease the lights themselves… and also generate revenue through charging them for customers.
How can I generate electricity with a bicycle? | Environment

To build a bicycle generator you’ll need the following parts. Bike, stand, DC generator, charge controller, batteries, and inverter.
The bike is placed in the stand with the rear tire on the generator. Then the generator is hooked up to the batteries through the charge controller. This prevent under and over charging your batteries. After that hook up your batteries to the inverter and you’re done. The inverter will have a regular plug for electronics.
Use more batteries to store more energy or larger inverter to power more wattage at once. A 400 Watt inverter will be enough for most household electronics except an entire desktop computer setup. Go with 600 Watt if you want to be sure.
I dont know how to store it but to, say light a bulb, you need a cylinder covered inside in copper wire with something connected to the bike wheel that will rotate and cause friction on the wires. These copper wires need to be connected to the bulb outlet and vooilaaa!!! Good luck bud, you can probably power a radio with a bike… maybe a tv.
This time of year, as I've mentioned in other articles, it's important to make sure you have what you need to see and be seen when out on your bike. Before I give you my thoughts and advice though, what is the law regarding bicycles and lights?
The whole lot is driven by a Shimano front hub generator and includes a rear light which, like the front, has a built in capacitor so that the light stays on for a good few minutes if you stop at traffic lights. The bike complete with a pair of Elite
That energy can be supplemented with the bicycle generator." He also gets solar energy from old cell phone batteries. All of the lights in his home utilize only solar energy! This represents a significant drop in electricity costs.
