I am looking for trailer suppliers as I am designing a mobile sound system pulled by one of my cycles. It will need to be robust and suspension would go well
What exactly do you want to carry? Size/dimensions ? swept volume, weight - and how distributed re CofG considerations?
Which parts - specifically would you prefer to be protected from shock loads / vibrations etc?
Storage when not in use - collapsible / folding or not?
Ebike or not / total weight target - what access to materials / tools etc do you have?
Real pros and cons of single v twin wheel rigs for your specific needs - not related to whether one or the other pops up at a 'good' price.
When stationary, a single wheel trailer will need two extra support points - a two wheel trailer only needs one.
there's been a few CC members building their own trailers. Maybe search the forum for ideas. Something so specific might be best built by yourself utilising BMX wheels or by chopping up a robust pushchair.
I'm one.
Nothing around for my requirements so made my own based on a stroller buggy frame - and it folds - no details here, see appropriate forum (projects, builds etc)
'Robust' I would most definitely question, based on the final all up weight. There are way too many examples of overweight trailers around for the loads being typically carried. Any extra weight is a right pita - especially if using a normal bike (as I am)
This interests me. For that sort of price I can afford to buy all the bits and a welder and make two, sell one and crack on
No welding involved with mine. I have no idea whether you can weld, but if not, buying a welder and starting from scratch - especially if proposing using thin gauge material - best of luck.
