I had a cheap recumbent exercise bike that I wore out awhile ago, and now that it is winter again it's too cold and rainy for normal bike riding. So I was looking online for a new one to buy and even the cheap ones seemed to all be "magnetic resistance" based.

The question I have, if anyone knows, is: will they screw with any nearby electronics (tv, video games, computer), especially with the resistance turned up?

I honestly don't know how large a magnetic field is created by these things, and the sales people aren't going to say anything that will hurt their commission.
