The problem with every portable Bluetooth speaker is that they’re very limited in battery life, especially if you’re doing things like camping, traveling or even out for a long bike ride.
Specialized for bike riding but capable of being used anywhere, the Solker (a hybrid of the words “speaker” and “solar”) harnesses the sun’s energy to ensure you always have music when you want it. A built in solar strip recharges the battery as long as the sun is shining. Designed to fit the water bottle holder on your bike, simply drop it in, ensure the strip is facing up and enjoy endless tunes while you’re on your ride!
