The only wheel I use with rodents are these
http://transoniq.com/. If you go to the "others gallery" page you'll see my clumsy duprasi happily running in her wheel. They kept falling out of open wheels and the enclosed wheels were too narrow for their fat bodies. My gerbils absolutely loved having one hang from the top of the cage so they could jump into it. That also kept them from easily chewing on it. I've had alot of problems with other wheel designs so there is no other type I can recommend as safe.
