There was a problem filtering reviews right now. Please try again later.
I got this bike to replace one that had worn out and was not repairable, so my first consideration was that I could service it myself and the second was price. It's dirt cheap, so that's great.
The one little hiccup I had was that the bike came from the factory with the chain tension too tight. The seat would sort of vibrate at the end of each stroke. It was possible to fix, and I did, but I had to read the comments to even know it was a problem. You should not just let this bike break in, because it would just break.
Also noise levels weren't nearly as bad as I feared. I have the felt pad model, and I ride it while watching TV and it doesn't interfere with that at all (I don't have to crank the volume to hear the TV).
Anyway, it's a great bike as long as you know to loosen up the chain tension a bit after you get it. (This will require removing the plastic cover and turning two nuts about one full turn. It's not so bad.)
1) Very sturdy, regardless of pedaling intensity
2) Easy assembly
3) Great value, especially if you're not sure if you'll use an exercise bike
4) Chain is actually very quiet; no slippage issues like reported with other belt bikes; I thought this would be a problem but it has worked to my advantage
5) 20 lb flywheel is more than adequate and provides a smooth pedaling action
Now, the bad:
1) Handle bars are a bit uncomfortable, but were easy to construct a custom wood laptop holder
2) Seat is uncomfortable; currently investigating a good seat cover
3) Seat is not interchangeable and not a standard bike seat mount; it's bolted to the mount; no tilt function and limited adjustment for height and front-to-back
4) The monitor is of limited use and hard to see (it's not back lit); it toggles among calories, time, and mileage, but I use it only for time
5) Front rollers are way too small in diameter compared to metal roller mounts; use extreme care not to scratch floor
6) Had to glue catch that engages monitor sensor; should have two screws to prevent slippage
Summary: Great bike if you're on the "fence" about cycling; not enough adjustment for taller than 5'10" but could handle more than 210 lbs with no problem. I'm very happy with this purchase.

The pros: It was simple to assemble, doesn't require electricity (outside of batteries for the counter if you want to use it), and easily adjustable. Plus, much less in price than a Schwinn or Echelon
The cons: the seat that comes with it is uncomfortable. No place to set my device to read or operate while I'm riding.

Some of the parts were clearly refurbished as well. The legs smell very strongly of cigarette smoke.
Don't waste your money, get something a bit more expensive and it will last longer.
Photos show broken (there were three) ball bearings. And the inside cup was warn down. Cheap metals were used.

I'm seeing reviews that are saying it's silent - so either there's something wrong with mine, or those reviews are paid / fake.
I reached out to their support e-mail, and was told that since it's a chain drive - it'll be noisy. Fair enough, but my actual bike is quieter than this and doesn't vibrate nearly as much.
I'm convinced something is wrong with it, but can't really tell what's up. The chain is tight and well lubricated, so I don't think it's that.
I'll likely return this as it's not a very comfortable or enjoyable experience as I can't really concentrate on a ride due to the noise and vibration.
Also, the computer is kind of junk and doesn't seem to factor in resistance at all - so I have no idea how "far" I'm actually going.
