I never had a bike bell, so the best option is to mount a speaker on to my bike and play all sorts of sounds, RIGHT?
This chassis allows easy access to buttons and ports of the speaker. Nuts are embeded inside and have to be inserted in mid print.
Firstly screw the chassis to your bike, then put your JBL speacker inside, and screw the lid with M5 screws
