Awesome value for indoor cycling
First of all I received this product just two days ago. So I can say nothing about longevity or lasting build quality. However the welds are not sloppy and everything feels very Sturdy so I expect no issues whatsoever.Now getting on to what I do know. Sunny has made a name for themselves by making very affordable fitness equipment that is very well built for the price point. This bike is no exception. My girlfriend and I both use it and there’s plenty of adjustments so we can both easily get comfortable.The belt drive system is pretty darn quiet. Regular speaking voices or a television on whatever your typical volume is will likely be louder than the bike. There’s no squeaking or clanking or anything like that on my unit. The belt system is pretty neat because there’s no real maintenance or anything that you need to do to get it set up. (As opposed to a chain that would likely need greased/lubricated in various places)The computer that’s included isn’t super fancy but it works just fine. It would have been better if it included RPMs but if you really want it you can buy something else to measure that. Assembly wasn’t an issue either. All of the difficult stuff is done for you before the bike is shipped. The only negative I can think of is the friction pad that provides the tension on your flywheel will need replacing. I’m not sure how long it will last but I’ve been told you can buy them from the manufacturer.Overall based on initial impressions and the first couple of rides I’m more than pleased. Everything is well built and functional. If you’re looking for an affordable indoor cycling option this should do nicely for you. It works for me.

Decent spin bike at a great price
I've wanted an exercise bike for a long time but the cost was prohibitive. I hadn't been on spin bikes in roughly 20 years but when I saw this one at such a good price with decent reviews, I figured it was worth trying. I was at first disappointed in the packaging - it came in a box that was pretty damaged and I could see some of the metal of the bike through it - but once I took the box off completely, I saw that the parts were actually wrapped quite well and the visible metal was just an extra (high quality) part for packing purposes only. It did take a while for delivery, and they changed the delivery date on me twice, but it still arrived by the last day promised. The directions were comprehensive and it was pretty easy to put together. My only complaint is that the drawings were VERY small and I had trouble reading it. But with a magnifying glass, it was detailed and easy to follow. The bike has required tightening a couple of times as I've broken it in, but "real" bikes require that as well. I've used it almost daily since its arrival. It's quiet, works well, gives me a great workout, and while the computer looks fairly cheap and had poor reviews, it's been working so far. Most don't come with the computer or water bottle holder at this price, so I figured if the computer worked at all it was a bonus and if it didn't, oh well. So far, so good. It works as well as the spin bikes I used all those years ago, I can easily watch TV or spin videos while using it because it's quiet and has a platform for me to keep a book, tablet, or phone. And for the price, I could find nothing reviewed close or better. It may not be a 5-star compared to a Pelaton (though I've never used one), but this is 5-stars all the way for the price. Couldn't be happier!

the shipping is amazing. It was pretty much overnighted to me
So I was between a few different Sunny Models for a spin bike. I've had the bike for about 1 week now, and have used it twice.First, the shipping is amazing. It was pretty much overnighted to me. I was very excited to try this out, but the box is heavy! Just under 100 lbs.Unboxes was easy, but there was a hole in the box (side dent), after inspecting the contents, nothing was harmed.Sliding out the box, the bike is broken down in a few pieces, but the main piece, with the flywheel and frame, is the heaviest piece.If you're moving the bike somewhere (through floors or something), carry it piece by piece.Assembling was easy. All tools and instructions were clear, and I got it done with my dad in under 30 minutes.Using the bike:First, there were some stability problems with this bike. I've used plenty at gyms, but this one has two wobbles. The handlebars are a bit shaky because the slider portion doesn't hold the bars tight.The seat is also a bit wobbley when I was riding.Doing my jumps, I felt the bike shift a bit. I readjusted so the bike was even, but it felt slightly unstable on the harder ride.However, the great things about this bike:It's quiet. Belt drive is like a little swishing sound and that's all.The seat isn't terrible, but it's definitely nicer on my butt than the ones in the gym.It's solid/heavy wheel is really nice. Gives a smooth ride.The little tracker is a nice addition. Tracks everything pretty accurately. (Compared the calorie burn to my FitBit HR and they were only a few cals off). The distance might be overstepping, but that isn't important to me.Overall, I'm happy with the purchase. I do wish it felt more stable, but I think with some tweaking, it should be fine.Gives me a great workout, the front wheels let me move it easily, and it was a lot cheaper than the couple extra hundred on top of this one some others cost.

Nice bike
Very nice bike but a lot of assembly is required. I found the instructions clear and easy to follow. I took it slow and didn't time how long it took to complete the assembly. The bike is very stable. I have a bad back and was concerned that I might have an issue if I had to lean forward to ride the bike but, it is easy to ride sitting up. Don't even need to hold on to the handle bars although I wish they could be adjusted so they face toward the rider instead of away. For me, I found the 7in wide seat to be uncomfortable so I ordered a larger seat. Otherwise I have no issues with the bike. There were no missing parts.
