from memory you select km/h or mp/h by using the left button to change the option and the right to select.
then you measure the outer diameter of your bike's wheel and then enter that in.
i am only 80% sure this is correct
A bicycle computer, also called a cyclocomputer, calculates and displays trip information, similar to the instruments in the dashboard of a car. With additional sensors, other performance measurements are possible.
In reality that answer would depend on the width of your tire, and on how inflated it is. If you're looking for a value to enter into a cyclocomputer, do a roll out instead. But a short answer is that it's about two metres.
If you use a bicycle speedo/cyclocomputer you get all you need in one neat package. Just make sure you enter the right values for wheel circumference.
Depends on the voltage and amperage of the battery vs. the voltage and amperage required of the bicycle.

You'd need a bicycle with a generator, and then some adaption electronics to turn the electricity from the generator into something that can be used for battery charging.
Either a battery or a dynamo.
Yes if it is used to charge a battery.
Can be just about anything, from a small button battery for a small LED, to NiCd to Li-Po.
You can buy a battery powered light at the bicycle shop.
A motorcycle (motorbike) is driven by a petrol engine. A bicycle is driven entirely by the effort from the rider (unless it is battery driven).
You could try and hook up a bicycle workout machine to a battery so when you work out in the morning, you charge the battery. Then put the battery in an electric car.
