Wahoo Kickr Snap Smart Wheel-On Trainer. $115 OBO.

I used this a few times a year during the last couple indoor seasons. The trainer works great with no issues at all. Wahoo has their own free app to use it as a smart trainer, just set the resistance or use with any other trainer app available out there including something like a Garmin device with suggested workouts. I typically used with with Zwift or had my Garmin control it. Doesn't include the wheel block.
