Hello, I want to mount a Braven BRV-1 bluetooth speaker to my bicycle (which is a pretty generic beach cruiser). This particular speaker does not come with any hardware to support a mount. Does anyone have any ideas or experience for mounting things to their bike? Note the speaker would have to be easily detached from the bike as well to recharge. Thanks in advance for your help, I'd really like to figure this out.
