I’ve tried many of the big name and model airbikes. I liked the idea of a better airbike wanted the stealth to be part of my home gym and possibly a solid bike if I restarted training/coaching clients in person.
I think that I ordered the stealth pretty soon after it was available on the site. With that being said, I most likely have generation 1 and may not reflect any updates. I received the delivery in August 2022. After assembling the bike and trying it for about a week, I sent feedback to torque which they were quick to respond.
My feedback included the following: 
1) Basic issues were the instructions didn’t match all tools and measurements. 
2) The seat post would not tighten enough to secure the seat
3) monitor wattage didn’t seem accurate, 3 digits, and would max out.
4) bike makes a knocking sound.
Updates: 
2. Torque sent me a new seat post assembly that resolved those issues.
3. I received a new monitor that resolved the above mentioned issues. The new monitor seems to have less contrast, my lighting could be contributing and/or I may need to add new batteries.
4. No additional guidance on the knocking sounds.
Pros: it’s the most solid airbike that I’ve used. At full intensity, it doesn’t move, rock, or sway.
Cons:
* see above issues
* price. For the cost, I could have bought an airbike that wasn’t as good and torque’s entry level tank.
