Bicycle generator for lighting a led strip?

I want to make a bicycle power generator for a fair. I want to make two of those in such a way that the one who pedal faster get more number of led bulbs turn on. Can anybody help me with this kind of project.

Try the LM3915 or 3916 for a wide voltage LED dot or bar graph display. As the bike generator is turned faster the voltage increases lighting more LEDs...


....and make sure you put a load resistor on the generator.....
