Recommended Hardware
Hardware can be sourced for two versions of the SmartSPin2K - Legacy and PCB. For new builds, we strongly recommend the PCB hardware.
This sourcing guide assumes you have a spin bike that reports wattage over bluetooth or a spin bike with a bluetooth power meter.
You should be able to source all components for < $100 USD including shipping
