great bike at this price point

I bought this bike because someone on Twitter recommended it as a super sturdy, super affordable alternative to a Peloton. It has not disappointed. This is a bare bones bike- no lcd screen, no device mount. What it does have is that 49-pound flywheel, which gives a better “road feel” or whatever, and it has a water bottle cage, which is useful. The bike itself looks sleek, it is compact (only a 4’x 2’ footprint), and with no clunky accessories it looks minimalistic and uncluttered. To make the bike function as a Peloton alternative I just added a phone mount and a Bluetooth cadence sensor, and it works really well. The bike offers a smooth ride, it’s quiet, it’s highly adjustable, and it doesn’t take up much space in my house. My two minor complaints are that I can’t ever get the seat tightened enough (maybe -probably- my fault), and, I’m unable to find a hand weight rack accessory to buy for this bike; it’s the last mod I want to make and so far only Etsy sellers seem to have any (and even those are sold out). So, Sunny, can I get a hand weight rack for this thing? That’d be great. Otherwise, I love the bike and use it almost every day.

Basic but good!!

I have already been on the bike for 2 weeks and so far so good. It is a very basic but sturdy bike. It is medium to small in size. It is for domestic use. It comes very well packaged with complete accessories and very easy to install. They are very well value for money. It has a very good finish. Actually the resistance lever comes from Leather material. It will look very cute after assembled.SUNNY BIKE cover is made of plastic.

Best Bang for Your Buck

Works great, great quality and great VALUE. I was looking for something to train with over the winter and this meets my needs perfectly. I'm planning to buy power/cadence pedal meters from amazon for $40 and a heart rate monitor for $30 as well. All together you then have a smart bike/peleton/norditrack solution that costs only about $400 dollars. Only gripe is that its not completely silent when adding the manual resistance but unless you buy a magnetic resistance bike, that is to be expected. Still quiet. I love the bike and would recommended this model for sure if you're thinking about a spin bike. You can leave it base like this or do cheap add ons, but either way its worth every penny.

Thrilled with this so far!

I have used my bike 4 times so far and love it. It's my first time owning any major home exercise equipment, and I'm new to indoor cycling as well. This purchase was certainly to prepare for being stuck inside most of the winter. The product shipped quickly and arrived a couple days early. The box is over 100lbs and required three people to carry it up to my 3rd floor apartment. The assembly was easy, and I was able to accomplish it on my own, however there was one flaw with the back. The screw holes on the handlebar mount and handlebars did not align. I contacted customer support, and they shipped replacement parts, which were received about 2 weeks later. While it wasn't ideal that there was an issue with the initial pieces, the customer service was wonderful, and the bike works great now. I mentioned that I'm not to indoor cycling, so I'm also so thrilled that Sunny Health offers free Youtube videos. Those have been excellent for a beginner to get the bike set up properly and to learn basic positions. I highly recommend this product. Very affordable and a small footprint in my apartment.

I just purchased this bike a few weeks ago. Easy to assemble and great ride. I am not a super cyclist, so the bells and whistles were not needed for me. I highly recommend this bike for anyone who wants to get in a great ride a few times a week. I love doing SPRINT class on this. 5/5 in my book
