EBeen meaning to get a new lock for my bike. The one I have is year's old d-lock and would probably yield with a sharp tap from a hammer but as I rarely leave my bike locked up in public places I've never felt the need to get a more up to day and, most importantly, a more effective one.
But now I'm planning to change yoga classes which will mean using a railing to lock my bike to on a main road so off I toddle to Cycle Surgery where I am sold this all-singing, all-dancing kryptonite* lock, with wire extension for the front wheel, complete fancy light-up key for those dark nights locking and unlocking my bike.
And why was this such a wise purchase? Well, because the guy in the shop told me about how, using a common and garden biro, you can pick a d-lock and just to prove it some kind person has put this clip on You Tube:
* Not even superman can get this lock off
