Here's a fun hypothetical for you who are better versed on the math and science:
How long would it take to charge a LEAF using a pedal powered bicycle generator? How about 2 or 3 or 4 of them?
Here's some data that I found from http://www.windstreampower.com/Bike_Power_Generator.php:
Fun thought experiment huh?
What if you were towing a trailer full of people pedaling? Could you pedal fast enough to maintain speed? haha Doesn't sound too safe though.

The average person can expect to produce in the range of 80 to 150 watts sustainably, charging variably at between 7A - 16A. The Bike Power Generator has been designed with a generator capable of handling 20A of current. When used to charge a 12 Volt battery, this produces a maximum PEAK power output of around 275 Watts (13.6 V x 20A = 272W) or just over a third of one horsepower (One horsepower is equal to 746 Watts).One can expect the peak output only in very short bursts. Power output depends entirely on the person pedaling
While it is possible to directly power some DC appliances such as water pumps, the Bike Power Generator is primarily designed to charge a deep cycle, 12-Volt battery or to contribute to a 12 Volt battery bank. Most household appliances require alternating current (AC) which requires a DC to AC inverter (see our Portable Power Pack). Certain DC appliances, such as DC lights, can be powered directly, but it is important to observe maximum voltage ratings to avoid damaging these appliances. It is usually necessary to use a voltage regulator or carefully monitor output with a voltmeter or multimeter. The output of a permanent magnet DC generator is variable - based on rpm and load.
