Same for me. I found out at low speeds I can do creative work for 40 minutes, typing on my laptop. I need to take break then as I feel too tired (mentally and physically), but it feels great.
What’s your set up look like? Do you have a standing desk that somehow fits over top of the spin bike? I have a standing desk but it doesn’t go tall enough to fit over top.
I have to admit it's a bit clunky. I chose a model with a tablet holder that happens to be stable enough for my laptop and the handle bar tall enough for me to pedal while sitting straight. So far it's good enough.
