This unit came ahead of schedule. It is easy to assemble with tools provided. Most of the fittings are based on using an L wrench. The nuts and bolts provided are all of top quality. The fit is also excellent so putting it together is not a problem. I suppose it took about 40 minutes but mostly because of carefully reading and checking the instruction. Once together. We put it in place on a Sunny mat which is a very good idea to also purchase. Moving it isn’t hard as there are small sheets at the front bottom. The unit sits very sturdily and without any rocking or vibration. The feet are adjustable to make sure it sits well. When in use, the unit is relatively quiet where one could easily watch TV. The computer is easy to use but it is reset on command and not able to continuously track more than one person. I would advise having a small book around for each to write down the record of each ride. The information given is time, speed, mileage covered and calories burnt. It can be set to display anyone of these or to continue rotate between these four metrics. There is no place for a screen or laptop or phone at the handle bar area. The saddle can be adjusted in height and fore and aft. The handle bar is fixed as is the tilt of the saddle. One thing would greatly improve this unit is the handle bar height and the seat tilt could be adjusted. It would also be nice if the seat could be swapped out for any regular bike saddle. Overall for this price point, this is an attractive, small profile, quiet and competent stationary exercise bike. It isn’t any where close to as enjoyable as riding outside in nature. But with our severe winters, this will have to do.

Great price (less than $120 when purchased) for a beginner bike. I wanted to see if I would stick with it before I invested a lot of money in a bike. I'm 5'10" and 200lbs (okay, 210lbs). First, the good:
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.
