Many people use bike trailers to bring the beat at large group rides like Critical Mass. Trailers make it easy to get started, since you can use a simple box rather than having to engineer a cabinet that surrounds your rear wheel.
But trailer-based systems put the beat much further from your ears, meaning that you have to turn up the volume much louder to feel like you are ‘in the music’. This means you’ll end up using much more powerful amps and speakers, and larger, heavier batteries. All this means that you are much less likely to use a trailer-based party bike for impromptu cruises (with 5-10 friends) and more likely to save it for larger, planned rides.
I love the bike culture touches this fabricator put on his system – the bike wheel and sprockets used as speaker grills. But there’s no escaping the fact that this system, and all trailer systems, look like a bike towing a box.
In my opinion an integrated long-wheelbase party bike, a Soul Cycle, is a much much easier way to create a cosmic ‘craft’.
