Apologies if this has been beat to death already. Though I like gadgets my bikes are all vintage steel and I usually hang out in the C&V when on BF. So if this has been discussed before I wouldn't know.

My sweetie (i.e. wife of 41 years) won't let me ride these days but we have a CycleOps trainer so I've been putting in indoor miles even after the snow around here disappeared. I've been thinking of how I'd run a terrain app like Rouvy or Zwift on my TV. I can connect my laptop to the TV via HDMI so getting the visuals up is not a problem. I don't need the smart-trainer feature of pedal resistance magically varying with virtual terrain. So I think the only hardware I need is a speed sensor on the rear wheel of whichever vintage bike I choose to mount on the trainer.

This is all new to me but it seems like a really neat idea. The only problem is, when I look up speed sensors on Ye Ol' Internet, I get very discouraging reports. Sensor's don't always work or aren't compatible with such and such or if they are compatible no one says so.

Do any of you have any recommendations of what works and is compatible with those software packages? My new computer with Windows 10 does Bluetooth, but I'd need a dongle to use ANT+.. I'd just as soon not spend money unnecessarily, but money spent on something that doesn't work is money wasted entirely!

Thanks!
