You get a nice box in the back or whatever but it's not really THAT much bigger than a box you could fit on any old regular bicycle
You can plop like two children there but then you can do that with Long Johns and 3-wheelers and such, too and ALSO you have the fuckoff-big box. They don't really seem all that shorter than comparable versions either.
Anyone got one or know why someone got one?
the box on a traditional long john isn't usually wider than the handlebars tho
Not wrong. Maybe it's perceived as nimbler? Maybe it's the local market? I dont see many Long Johns here (belgium/france/switzerland ).
The steering mechanism is different, though. Might present more of a maintenance difficulty over just a longer chain with a tensioner.
