Power Acoustik Black Motorcycle Bluetooth Speaker System FM Radio & USB Input

these are good for a 28mph or below bike, i do not see a use for these on anything stronger or with a gas motor. i have another bike that goes over 35 and with an appropriate helmet you wouldn't be able to hear these even at full volume. the fm radio gets very spotty reception so BT is the best option. cons: -bad fm reception -blinking LEDs that can't be turned off -low volume pros: -buttons on the speaker to increase volume, skip tracks, play/pause -mounts very well and the speakers stay in place -volume doesn't get loud enough to keep you from hearing what's going on around you(volume is a double edged sword) overall I'm happy with these, in fact I've purchased two more pair for relatives' low speed (class 2) ebikes. but if you ride something with a muffler or goes over 30, look elsewhere. i have a set of boss motorcycle speakers on my faster ebike, while their clarity is lacking, they are probably at least 3 times louder.
