A belt drive bike generator or a roller style. The roller style generator is quick to setup, but is 10% to 20% less efficient than the belt drive system when you go into higher wattage ranges. Also the roller type bike generator can be up to 2x more noisy than the belt type if your bike has mountain bike tires on it. In the most basic of terms, a bicycle generator creates a potential energy when you move the pedals on your bicycle. The potential energy is measured in terms of “Volts”. The faster you pedal on your bicycle, the higher the Voltage reading from your generator. If you want to see a video demonstration of how this works the go to http://www.youtube.com/watch?v=mCI_Ke1tA4o When you have nothing hooked up to your pedal power bicycle generator dynamo, you will be able to pedal with no effort at all. But as soon as you connect an electrical device to the generator output like a light bulb, or a lead acid rechargeable batter powerpack, then you will suddenly feel resistance to your pedaling efforts.

Customer Review  GOOD ALTERNATIVE ENERGY / BACKUP POWER, January 11, 2011 (Phoenix, AZ)

I use this system to charge a 33 Amp Hour battery through a blocking diode and it works pretty good. For those technical geeks, the output during the same one hour period from this bike generator (measured by WattsVIEW power monitor) was 5.4 Amp Hoursand ~70 Watt Hours. During a one hour period, I was able to bring the battery from 0% charged to 40% charged. I have also used this generator setup to charge a Duracell 600Watt Powerpack which was nice so I could plug in regular 110V AC appliances into it like laptop, computer, cell phone charger, lights, television, blender, and more.

What I don’t like about this system is that I have to take the rear tire off my bike to put the belt on. ALso, if I try to put out anything over 200 Watts, I have to make sure the belt is really tight, or it will begin to slip.
