Actually, no on the cyclists. Daily global fossil fuel production in 2006 was the equivalent of 155 million barrels, which is 913,900,000,000 MJ, or around 130 MJ per person. The average person eats around 2500 calories, or 10 kJ, less that 0.01% of the energy needed to power their own energy needs by bicycle, even if food were converted at 100% efficiency, and fossil fuels were the only energy source we needed to replace.
