I really like this bike and so far seems durable, but get a proper saddle!
I ordered this on March 21, 2022 My PCP told me I needed to start exercising in a way that was better for my knees, so cycling it was. But I live out in the county and it is primarily gravel roads, so I ended up deciding to just get a stationary bike first. I'm a large man, 250lbs and 6ft6" tall so it was a lengthy search finding something in my budget that would work for me. My legs were still a little too long for this bike but it was close enough I could still use it without feeling overly cramped. Assembly was simple and it feels very robust, I was actually impressed by the weight and rigidity of the materials. I get zero flex or wobble after properly adjusting the feet heights on my tile floor. I had doubts about the durability of the belt drive system, but so far I haven't had any issues and it's definitely much more quiet than some older chain drive stationary bikes I remember riding in the past. There were a couple things that were a problem though. The bottle holder placement is very awkward while riding. You can't exactly coast on these like a regular bike so grabbing a water bottle while peddling is impossible for me, mostly due to my height. I really wish these had other optional mounting heights and locations. I'll likely drill higher holes and install some rivnuts to move it up. But for now I've just been stopping to take a drink. And the other issue was the seat. I absolutely HATED the seat on this thing. It did not fit my anatomy at all and was way too squishy in all the wrong places. I now have a properly sized Brooks bike saddle installed and it makes a HUGE difference. Soooooo much more comfortable! so much so that I can ride this thing for hours without my butt hurting. And The seat mounting bracket can be removed from the original seat and be transferred over to the new saddle. Was a very easy process. Also, based on the advice from a friend that is an experienced cyclist I determined where to better position the seat for my long legs and increase comfort even further. But to do this I had to modify the mounting bracket. Even after adjusting everything to the maximum position I still couldn't get a proper leg extension. But after the modification it is absolutely fantastic and due to the build quality I don't expect to need a replacement for many years. With the seat so far back I did occasionally rub the riser post with my thigh, but it's nothing painful, was just barely brushing up against it. But after getting some proper cycling bibs it never happens anymore due to the compression at the thing. So if you're slightly too tall for the bike, you can drill a hole in the seat post plate and flip the plate around and then bolt it on to get more length. BUT it's not easily adjustable now, so if you have multiple riders In the house I don't recommend this.

In love!
I did a ton of research before purchasing this bike, and this may be the best fitness related purchase I have ever made! Like many others, I wanted a Peloton bike, but simply couldn't justify the price tag! This seemed like a great option, the reviews were solid, and for my budget, it seemed like the perfect solution. I am happy to say I am beyond satisfied. The bike arrived within 2 days. Box was slightly damaged but the bike inside was well protected and completely unharmed. As everyone has mentioned, this bike is HEAVY! Be prepared to have some help getting it in place. It comes pretty much assembled, and what wasn't assembled took me about 20 minutes to put together once I had the bike where I wanted it. All of the "tools" you need for assembly are included. You have to change out the stabilizer bars in the front and back (it comes with smaller versions attached for shipping purposes, each is removed with 2 bolts) you need to install the handle bars and seat (unscrew the bracket with your hands, put the seat and bars in place and replace the bottom of the bracket-took like 2 minutes each) 2 screws for attaching the water bottle holder, and then the pedals, which was probably the trickiest part. Be sure you have them on the correct side (there is a right and left with pedals!) and that you are threading in the proper direction. I myself did purchase Shimano double sided clip/clipless pedals as I prefer to use my cycling shoes which have cleats. That is the only upgrade I have made so far and the bike is still awesome! I downloaded the Peloton app, which is amazing but does have a monthly fee (though you can try it free for a few days without even giving out credit card info to see if you like it) There are also classes on YouTube which are free if you are turned off by the cost of the peloton app, but I absolutely love it. I use a heart rate monitor so I can see my calories burned on there. I could see myself possibly purchasing a sensor to monitor cadence at some point, though I find myself just keeping time with the instructor in the app works fine for me. MANY people have complained about the seat on this bike...however it is not unlike the seats on spin bikes at the gym, which DO take a few classes of riding to get comfortable with when just starting out. I did NOT feel the need to change it out or add a gel pad. Sometimes having a larger seat with more bulk is actually less comfortable. Overall, everything about this bike is super solid. The flywheel was well adjusted already and the bike is pretty darn quiet. (Sounding much like a spin bike at the gym). Also, I am able to move this bike around on my own quite easily now that it is assembled. It takes up a minimal amount of space too. For reference, I'm 5'2 and I am not adjusted to the lowest settings on the seat or bars, so it would work just fine for someone shorter in stature, and there's lots of room to adjust for taller folks. If this is your first experience on such a bike, I highly recommend you take the time to read or go on YouTube or and watch a video about bike set up. There are some specifics about positioning that will not only make your ride more comfortable, but will protect your knees from harm as well. Happy riding!

I was looking for a straight forward exercise bike without the tech or monitor because I'm not interested in knowing my heart rate, distance, speed or timer, nor am i interested in online classes with someone reeling a list of motivational clichés to keep me going (you know the brand name). I purchased this on 22/12/2022 and paid £159.10 sold by Amazon EU S.a.r.L then a couple of days later notices the price hiked up to £329.99 glad I'm brought this when I did now, plus there isn't a warranty on this outside USA I'm in the UK. Setup was easy to do and the tools were included, but keep hold of the manual as it has instructions for maintenance required for daily-weekly and monthly including belt tightening should a problem arise. Also Sunny have some maintenance videos on YouTube to help you with removing the felt/leather pads for oiling but you can also use a clean wire brush to rough the leather up a bit for extra friction. So having used this for 1 week now I cannot fault this exercise bike it has been silent to use. I set a 45 minute timer on my echo dot and the bike is Infront of the bedroom TV and I watch indoor cycling on YouTube so its like having a cycle simulator and its easier and safer as its winter months with cold dark mornings to roll out of bed and use this set up (cycling around the alps LOL) than dragging myself outside in the wintry conditions. Overall I'm pleased.

I just got this and assembled. Easy to assemble but the spanner the provide for the lock nut on the pedals is not effective. I used a pedal wrench I had and and was able to tighten. First workout was good but at 6'-1" I wish the seat could go back just a smidge more. Smooth quiet operation. I will update in a week with more workouts completed.

me daba un poco de duda por lo de que fueran a faltar piezas, pero viene casi todo pre armado, es muy poco lo que hay que hacer. me sorprendio que no se escucha casi nada de ruido, el poquito ruido que hace es por ponerle algo de resistencia, si lo dejas sin resistencia 0 ruido, no despiertas a nadie incluso puedes ver la television o prgoramas en una tablet sin ruido molesto

Great bike for the price

So far so good. Received less than a week ago. Packaging was in excellent shape. Easy to remove from box and super easy to assemble!! Very solid construction. Easy and quick to adjust for different riders. Fairly quiet ride which was important to me as I often ride when others are sleeping. The seat is somewhat hard but may just need some breaking in. Knew this before from other reviews so no surprise. Using my padded shorts so not completely uncomfortable. Have already put on several hours in the first 5 days with some hi-intensity stand up peddling with no issues.
