Saris smart trainer (can be used with Zwift, etc.). This has only been used about 5-10 times - I just don't like riding indoors. It was bought in 2020, but has just been sitting in my garage.Suitable for seeing if you like it, etc.
IMPORTANT: you will need to buy a new power cable, as I cannot find that. These are $29 and can be ordered here:

Note it folds up, and includes a front wheel holder/riser (see photos). It is the type where you clamp your rear wheel in it (so you are using your wheel and cassette/etc. - it applies the load to your tire). I am including a skewer that you can use (if you have older style that it's compatible with to save your skewer). I also have a through-axle adapter for it (not in pictures). Otherwise, you may need your own quick release or similar to secure it, depending on your wheel setup.
