Racing Bike Camouflage
My bikes get stolen all the time (so far I lost 4). I know I have an insurance but the paper work and filing with the police is just a pain in the behind. So I invested 120$ into the toughest lock ever. Once I was in flower shop for 5! minutes and my bike was locked to a huge metal post which was part of a building. Of course it got stolen again.
Finally I realised preventing the actual process of stealing is useless. The only way out was preventing the thiefs from wanting my bike. So I painted it. This way the resale value the thiefs could get dropped to Zero. Of course I still keep locking it but since then nobody stole my bicycle again.
