Similar to Crackhead Strength you might encounter in the states. There's videos of sketchy looking folks hauling away anything they can find while riding bikes that were probably stolen too. One guy hoisted a fridge into his shoulder and biked it away.
I remember a video from long ago describing exactly what you mention. A tweaker riding a bike with a full sized fridge on his shoulder. Wild thing is that it wasn't even a full sized bike. lol. I think it was a BMX one.
