Very cool!

I'm curious about the effect this has had on your fitness. 60 W output on a bike is pretty low intensity exercise for most people, but 15-20 hours a week is a lot of volume.

Did you have to work up to that? Where did you start and what did the journey to where you are now look like?

Do you have a sense of how this has affected your capacity for higher intensity exercise? (If it helps to have a more concrete idea of what I mean by this, were I designing an experiment I would probably track max power output and power output at VT1 and VT2. But any kind of fitness metric would be interesting, as would be what you think the effect has been, even if it's not based on hard data.)

Prior to building it, I rode a bicycle for a living (https://www.pedalpc.com/about/), so I was in pretty good cardiovascular health to start with. FWIW, my resting heart rate is in the lower 40's. My heart rate is about 70 bpm when I'm generating 60 W of electricity.

Keep in mind 60 W of electrical output is ~100 W of human power output, due to generator and rectifier efficiencies. I would call it a moderate workout. I can engage in a normal conversation or video conference call without a problem, but would find it a bit difficult to sing.

You're right, I was not factoring in the effiency of the generation process. 100 W is definitely moderate or higher for most people.

This was the first time I had seen a cycle desk and I find the idea really interesting.

Having done a little more reading on the subject, my sense is that you may have a better handle on the ergonomics than the existing cycle desks on the market. It seems like most people are using cycle desks to do a pretty limited amount and type of work while doing a short workout, whereas you are using it for a long time each day, which I imagine means you can do most types of work comfortably.

If that's true, and it's true for a sizeable number of people, not just you, I think that's what I would focus on.

Are the other people for whom you've built one able to use it as much as you?
