I got an exercise bike today. It's described as a magnetic exercise
bike. I suppose this means the resistance is provided by a magnet

Do either of the bikes in question have electronic speed displays? If
so, has anyone tried removing the battery?

Good idea, mine has a simple one - but I believe all the displays do is
count the pulses generated by (I would imagine) a Hall Effect sensor as
the wheel spins.

Try some different wireless channels?

The bike is likely built as a generator, with a variable (electrical)
resistance to provide physical resistance. Assuming they just threw a
bunch of magnets and coils together without much shielding it'll be
throwing out EMI all over the spectrum.

Aha - so I'm not crazy. :-)
I got it! Wrap the bike in aluminum foil! Actually, that may not be a
bad idea, if you can isolate the unit spewing EMI try to cover it with
a box lined with aluminum foil. It wouldn't cost you more than $2 to
try and I'd love to hear the result.

Strangely I just did ~12 minutes on the bike and the Squeezebox worked
flawlessly...
It was certainly reproducible yesterday.
Oh well, at least I got everyone's brain cells working. :-)

Was the SB in the same physical location relative to the bike ? The rf
from the bike may be quite directional.

You may be on to something. The Squeezebox is directly in front of it,
about 7-8 feet away.

LOL!
Just to see how high I could get it to go, I reved it up to 45 km/h
yesterday. But at that speed my legs are pumping up and down so fast I
thought it was going to tip over. :-)
Most of my session yesterday was at
was the bike on the same circuit as the squeezebox? That has to be one
bad piece of exercise equipment if it puts out that much interference.
Are you using a wireless connection with the SB?

No, the bike has no electrical connection. The small computer runs on
two AA batteries.
It is a wireless Squeezebox3.
