That JBL speaker is cool but too expensive to ship to Ontario CA.
I bought this speaker at closeout electronics store and it's good.
I rigged up a handle bar mount to the speaker with spare bike light bar mount clamps.
This is the bike you are riding correct?
It is not designed for pedaling distance.
Does your bike travel 28 miles with throttle and pedaling on a charge?
cause if it does, throttle more, pedal less, you'll make it.
I have a bell for walkers on the pathways.
I have a USB rechargeable horn for traffic, honking at my neighbours as I zoom past their homes and for scaring the crap out of squirrels and coyotes on the roads and paths.
Sometimes I just use an audible BEEP BEEP.
