Never assume that your safe from theiving twoc'ers! make sure you have ground anchors, chains and everything holding your beloved down to the ground even if its garaged!

I fell into a false sense of security with my bike, left it by my back door, in a locked garden with 6ft fence panels and didnt think any oppourtunist would take it, but they did, they jumped over my back gate, dismanteled the lock, and wheeled the bike out with them

the bastids will try anything!

Which is why i have a bike no sane person would want to steal! - and STILL take the precautions! - BIG chain to a bike rack which is cemented into the ground + alarm +Immob + cover (helps alot, esp if, like mine, its a ratty old cover!)
