Bicycle Stereo Speakers
If you are looking for bicycle stereo speakers, we recommend to include bluetooth connectivity as a desirable feature.
Most bicycle stereo speakers come with built in SD card support. You can install your music file on a SD card and play them on the speakers.
Having bluetooth connectivity expands the usage of the speakers with other devices such as cell phones, tablets and even laptops. So you can even use the speakers while you are not on your bike.
