Riding a bike with earphones isn’t really recommended, but if you have to bring the tunes why not beat it out with the BikeBeatz. This speaker box contains two 6×9-inch speakers, a 240-watt amplifier and line-in port, which can be connected to virtually any portable music player.
It isn’t the lightest option we’ve seen, and no doubt those who share their music with the world may find not everyone has the same tastes in what is “good music.”
