Yes, I have my own spin bike. I have a LeMond Revmaster Pro that I purchased last year.
I found that having my own spin bike made it easier for me to put in the time I wanted to on it.
That is I wasn't having to plan my spinning time around the times that the gym was open.
Since January, I've put in 1200 miles on it.
I've been very happy with this bike. It is very quiet and really smooth. I have short legs (I have a 25" inseam) so I
wanted to be sure I didn't get one that would be too big. I know most spin bikes are very adjustable, but I'm not
sure all of them would accommodate me. My gym also had the predecessor to this bike, and so I was fairly
familiar with the Lemond bikes. This bike comes with 170mm cranks, I typically ride with much shorter cranks, but with
crank shorteners, I was able to get them close to the length that I typically ride with.
If you aren't sure which spin bike you want, I'd suggest either trying various bikes at different gyms, or looking for a store that sells gym equipment. I purchased my bike through such a store. I also asked the store for a recommendation of someone who serviced these bikes in case I needed something repaired at some later or future date.
