If I offended anyone with my satire I must be doing something right.

I built this generator last winter. https://www.brettoliver.org.uk/bicycle_generator.htm from plans off the net.
I got fed up with the regular power cuts we get. The generator is designed to keep my gas central heating boiler electrics running so I at least get some heat and hot water while the power is out. Can also be used for my laptop and internet too.
The inverter is powered from the battery and is topped up by the bike charger.

If strava datas are anything to go by, a Professional cyclist can generate an average of 300-350W throughout a 200 km course. Sprinters like Greipel can peak out at 1.300-1.400w momentarily during a sprint.

100-200 watt/hour for an sustainable level, 500+ peak for very short bursts of 20 seconds to a few minutes depending on fitness level. This means if you cycled on your generator for a whopping two full hours at a nice 160 watt clip, you'd generate 0.32 kw/hour of electricity. You'd likely burn something like 1000 Calories in the process. I can imagine you'd spend at least a few dollars to eat enough food to replenish the 1000 Calories burned. On the other hand, here in Arizona electricity costs about 10 cents per kw/h, so you're looking at it costing you around 3.2 cents.
If you were thinking more of an off-grid setup, you can do a 160 watt/hour solar panel with inverter and battery backup and stuff for something like $1000 and have a generator that produces power for 4+ hours a day, plus battery backup, for no further investment. Humans really aren't very cost effective power generation stations.

Here is a data point. I am a 46 year old Cat 3. Currently my FTP (that is my 60' avg max power) is 275w and my absolute max is 1325w. These are pretty so-so numbers for racers.

But can you power a 100 watt 110volt Load? running a dynamo generator,
to light a bulb like you have in your house?

Which is why The Matrix made no sense to me. Just kill all the humans, and install ground source heat pumps everywhere.
Back on topic: yeah, 100-200W is about right. Considering the speeds you can reach with such a small amount of power (compared to a car), it makes a cyclist a very efficient mode of transport.

I am chubby at 5'11" and 207 pounds and I can sustain an average of 250 watts for an hour. I guess my legs are just naturally strong. Too bad I'm not naturally skinny.
