Cargo Bikes

Welcome to the club. Now to complete your entry you need to load as much s*** as possible into it and ride around being sure to take photos in-front of a decent coffee or pastry place, bonus point for children or dogs (Don't have to be yours, can just find some of the street) burried underneath the stuff.

For the box, just sand it and varnish or wax it, paint it if you want but will likely flake off unless you have high level prep skills. Or keep as is, like a form of anti theft ;)
