Horizon M4 Indoor Cycle -- Great bike, if you can find it on sale, even better.
I read some of the reviews about the computer not working too well. Not showing the RPM's, well the little sensor that points at the wheel needs to be adjusted a bit. Push the sensor until almost all of the clear tube is into the holder clamp. Then you will see on the flywheel a small black disk, it's a small magnent, and the sensor has to pick it up. You may have to also adjust the sensor angle pointing up or down a bit. I spent a few minutes doing this while cranking the pedals until I saw the RPM's registering on the display. Also note that the RPM's are in MPH not KPH.
As far as bike computers go, it isn't the best, but on a spin bike you don't really need it anyway. I was more focused on the quality of the construction of the bike itself, which I must say is pretty good. It has a nice solid feel to it, the handle bars and seat are easily adjusted. It feels quite similar to a much more expensive Star Trac that most gyms use.
The flywheel rattles a bit, but nothing that you even hear once you have music going, or a spin class dvd.
I would recommend this to anyone looking for a solid spin bike for home use, and you don't want to spend a small fortune on it.
It's pretty easy to assemble as well, as there is only a few pieces to put together out of the box, took me maybe 30 minutes total.
