This is somewhat inspired by the box Emmet Brown has his plutonium in in “Back to the Future II”: 
Box is from Festool, ADR stickers are nicked from former employer… gets bungeed onto the back of the 'Bird 
Imagine the ensuing panic if it ever fell off and the authorities found it!!!:w00t:
Might a Festool box attract the wrong type of attention?
Now if only you could power the bike with this…
Hehe… the missus asked: “Is that to put your smelly socks in?”
