Cargo Bikes

Oh that looks more along the lines of what I need. Two or maybe even three of them stacked would be ideal, I want to be able to ferry large loads of smaller items. Might go with that option. Thanks for the tip.

I already have j-hook ratchet straps for carrying the soundboks speakers, which are 86cm high when stacked sideways. But they are stacked further away in the cargo area from the handlebars, so the bars don't knock into them when turning.

I'll look at the different sizes and see what could work with the Bullitt dimensions. Assuming that you can stack the different boxes on top of each other once one of the width or length dimensions is the same.
