1. Desk Peddler with a...
2. Cadence Monitor hooked up to a...
3. Programmable RPM Switch
Hook the switch inline on your computer monitor's power cable and start pedaling!
Imagine if companies installed these under each desk in the office. And... imagine if they were hooked up to a battery that charged from your pedaling and powered your monitor and computer?
I'm not drunk... I promise!
