BELT vs ROLLER: You may be asking yourself which type of pedal power generator to get. 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.

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.
