As for running in Unity Editor without a VR headset, you can hit "enter" when so prompted, and use the WASD to emulate leaning, spacebar/tab to emulate pedaling, enter/backspace to emulate A/B buttons, and arrows to look around. You could also use a compatible gamepad for emulation.
If you want to test your VZfit Sensor Kit on PC with your bike, you'll need a BLED112 USB dongle to connect to the crank sensor, a PC VR headset to measure leaning and looking, and would have to pair your action button to your PC.
