- Reviewed in the United States on June 4, 2022This bike is fantastic. Assembly from unpacking to finish took about one hour. The bike is quiet and easy to use. If you want a bike that doesn't require a blue tooth or a fitness app. THIS IS IT.
- Reviewed in the United States on May 4, 2020I’ve had this bike for a month and I’ve used it almost every day. I like the fact that it has preset rides (my main reason for purchasing) because I am not actually programmed to work harder when the opposite is far more pleasant. It is quiet so I can watch a movie with other people and still ride if I want to. It provides challenging rides and it plain works! There is a stand for ipad and lower down the iPhone fits just fine as I cannot get through exercise without tele. I cannot tell if the calories burned display is accurate or not so to be fair to myself i deduct 15-20% of the figure displayed and that seems about fair. The seat is fine when you get on, hard in about 15 minutes and gets unbearable at 60. It also seems to slope downwards a bit and I’ve decided to consider that part of the challenge and not whine on about it. Wearing padded bike shorts helps. Maybe my bum is just bony. I plan to add a gel cover when the one i like is back in stock. I couldn’t recommend it enough! And I have! Happy I didn’t spend a fortune on Pelaton plus subscription...really? The $2500 isn’t enough? Really love this bike!
- Reviewed in the United States on April 11, 2020I needed something to give me a good cardio workout during the COVID-19 quarantine. This bike will definitely do the trick. I've only had it for a day, but it seems very solidly built.
Putting it together by myself was fairly easy. I found it helpful to use a headlamp when connecting the computer panel connections to the wires in the handlebars. With the headlamp, I could see how the connection was supposed to be made. That was the most awkward part of the assembly to do by myself, but I got through it.
I also used a Phillips-head screwdriver on a couple of pieces where it was awkward to use their tool.. Other than that, I just used what was in the box to put it together.
The weight of the flywheel isn't provided, and I couldn't find it online. I did find a review that speculated that it's 20 pounds, but to me it seems to be 25 or 30 pounds. Considering the total shipping weight is about 79 pounds, my guess seems reasonable.
I guess it's not compatible with any particular fitness app, but I'm sure I can make do. Another reviewer stated that the measurements provided by the machine (calories, etc.) did not seem to be accurate, but that isn't a concern for me. I can neither confirm nor deny.
Over all, I recommend this bike. It doesn't take a great deal of floor space. You do have to plug it in, so bear that in mind. It actually has a USB port, so I suppose you can charge your tablet or phone while using it. There are two bottle holders on the bike, so you have your choice of locations. I like that there are many different workout settings, and hope that will help keep me from getting too bored. The display is bigger and more colorful than the ones I was seeing on other stationary bikes here on Amazon.
I used the Peloton app this morning, but am also interested in finding a good video tour app to provide scenery on my rides, for variety. I like that the stand provided for my tablet is at the top of the display. That seems a comfortable viewing position so far.
I'm grateful to have this bike, as it's already been a great stress reliever.
- Reviewed in the United States on March 24, 2021Very disappointed ... this bike worked, until it didn't.
The seat is super uncomfortable and it's impossible to get it to stay tightened and not move.
The computer is super glitchy, and it finally stopped working at all except in Manual mode.
Worst of all ... this product is made by MARCY -- that should be transparent in the description -- not after it's delivered and you see the instruction manual. That is deceptive.
I've had problems with other MARCY products and would not have made this purchase had I known.
- Reviewed in the United States on September 18, 2021I bought this bike so I could exercise at home while everyone here is asleep. It started squeaking after about a month of use, not loud enough disturb anyone though. I do like the variety of settings and it is nice to have it automatically adjust the resistant while I distracted watching videos on my phone.
There is a heart rate monitor accessory that does not come with the bike. If you fit type watch, I would not worry about buying the heart rate monitor.

- Reviewed in the United States on April 22, 2021I very much like that I could get a bike with this kind of computer unit at this price point. The color scheme is attractive, there are workout modes, and ostensibly good information. It reminded me of the bikes I would use regularly at a Planet Fitness. Some have described the seat as uncomfortable. While I did have that worry and perhaps that initial impression, I haven't experienced much discomfort sitting on it.
The main problem with this bike is that the information provided about distance and calories burned is WAY off. It's twice what it should be. I therefore have to consider this a defective product. The counters are simply not accurate and it's not even in the ballpark. I also had one of the pedals unscrew and detach on me the other day.
It's quieter than I'm used to but I suppose that's just the nature of a magnetic resistance bike. Buyers should be aware that you do need to plug it into an AC power outlet for it to work. Putting it together was a project but a few hours on a saturday and you're done. No part of the assembly was especially difficult.
I still love the way it looks. But the inaccuracy of the distance and calorie counts is a significant defect.

4.0 out of 5 stars Excellent after sales service
Quiet in operation, comfortable seat, big monitor display and wide range of resistance settings.
Had a problem with first machine delivered, but the Puretec service team response was great and they replaced it with in a couple of days. (Problems can happen with any make of machine like this, how the supplier responds is important and Puretec are excellent in this respect.)
