Heard across a street. Highly intelligent. A bike alarm like no other! $210 CAD. Direct from manufacturer: $120 CAD.
A collection of some of the various speakers tried in the years-long pursuit to achieve loudness at the smallest possible size.
Note that, initially, the goal was to design a system that could fit inside a bike frame! That had many ‘impossibles’ to overcome, the hardest of which was loudness. Even when the design changed to a product that would be mounted on a frame, loudness continued to be a goal never satisfactorily achieved–till I abandoned/postponed voice.
Not that loudness is impossible to achieve. Certainly not. But, the solution had to be one that’d fit the product–with limitations in size, installation, recharging, battery replacement, price, weatherproofing, fit for a variety of frames, etc. And no modifications were allowed to the frame! 🙂 And I have no capital/money to spend.
