Better you just get a resistance stand that attaches to your bike. For example: http://www.tacxflow.com/en_flow.html
There are many brands. Usually easy to find a cheap used one.
Life is good
+1 on riding your regular bicycle indoors (on a trainer similar to the above) rather than "riding" some strange contraption.
Those are really for non cyclists, the fit is horrid..
You may like real involvement, of Roller riding, three rollers front 2 are connected by a belt..
the bike is not attached.. so you have to keep from riding off the side of the rollers.
but if you want to read a book or magazine while riding, in place, a trainer stand is good.
