Does anyone know of a way to attach a speed sensor to something like this so we can zwift at work? https://www.amazon.com/DeskCycle-Exercise-Pedal-Exerciser-White/dp/B00B1VDNQA
I don’t think it is possible since there is no rear wheel and does not broadcast power.
If it’s standard threading you could attach Vector power meter pedals 
Not sure you would go very fast though. I have one too and pretty sure I spin at around 50 watts with it!
