Music and cycling go nicely together, but not hearing the world around you isn’t a good idea. So instead of jamming earbuds in that block the outside world a speaker that broadcasts the music to you might be the better way to go. There are plenty of handlebar mounted speakers, but then we saw the Scoche boomBottle, which fits nicely in the waterbottle cage and shoots the music up to you.
The shockproof device delivers the beats via two 40mm drivers and a passive sub. This plays music via Bluetooth or an auxiliary input, so you will need to broadcast that music from another device. Obviously this won’t work with every bike but this is clearly designed for those long solo rides not race day on a streamlined TT bike.
