I have used the iHome bicycle speaker a couple of years on our tandem bicycle (it is too long to fit in the limited space of my xsmall single bikes). When it works I'm happy with it. Unfortunately all the little bumps often cause it to loose connection. I've put paper shims in the holder for the iPod and that didn't help. I think the problem may be with the batteries shaking loose.

What I did like is the ability to quickly pause the tunes when approaching an intersection, so that we could hear any motorists while looking for them. Safety first!

Most people think it's cool and are even more motivated to draft behind our tandem, but we do have an occasional person feel that we are contributing to noise pollution. We try to be considerate and ask if it adds / subtracts from people's enjoyment of the ride.
