Sturdy, quiet, works well. The heart monitor is a nice touch at this price point. You need both hands on just the right spot of the handle bars for it to work and it takes about 10-15 seconds to get a proper reading but still, nice to have. Went together super easy. A lot of people posted issues putting it together which I didn't understand, there's only 11 pieces and they're mostly obvious. That was until I bought it and read the instructions. The pictures are the size of postage stamps and the description of what to do is terrible. So when you get it, don't read the manual just take a picture of the QR code in the manual which will direct you to a YouTube video that's simple and obvious of how to assemble it. I did find the seat very uncomfortable. Not sure why, the design looks ok and there's lots of padding but still after 10 minutes I just couldn't take it anymore. The seat is easy to swap though just like a standard road bike. So a quick search for a new bike seat on Amazon and $20ish later problem solved.
