I just finished my first ride after setup. I am beyond impressed. This bike vastly exceeded my expectations, which were set very low based on assembly of grills, and other in-a-box items. When I was growing up in the 1950's Schwinn was an aspirational bike. It was the one kids all wanted under the tree on Christmas morning. I had a Murray for a couple of years and begged my parents for a Schwinn. I finally got it and became one of the cool kids. This bike meets my childhood standard and shoots past it.
Here's what you need to know. A gear-head could set this up in 30 minutes. It took me a couple of hours-my fault not the bike's. There are no wobbles or vibrations. You would expect there would be. There aren't. It is as quiet as a mouse. No gear or grinding noises at all. It's very stable and you don't rock the bike riding it. I had originally wanted a club version of the Lifecycle. It wasn't available when i was making the purchase, and now I am glad. This one is better and saved me about $1,500 bucks to boot.
I do have one quibble. If you are a short person, this may not be the bike for you. The adjustment on the handlebar doesn't come as far back as desirable for max riding comfort. This is a weakness of the design. My guess is if you are less than 5'-5" it won't be comfortable for you.
Other than that it gets and unqualified endorsement from me. Get one and get riding.
Update 5-24-22 I've had this about a week now and 5-6 rides. I still love the bike, but the mismatch between the seat elevation and distance has started to bug me. I am 5-9" and need the seat about 2/3 extended to have a full leg extension at the bottom. I have to raise the handlebars to the max-they wobble a little here, to hold them. This is uncomfortable and transfers a lot of weight to my shoulders and wrists, and I can only maintain it for a minute or so. That has me balancing on the tiny racing seat that comes with it which is a little unsafe. I've ordered some extension hand grips to keep from having to bend over so far. I would suggest anyone buying this bike order some of these with it.
