Rolson padlock - cheap'n'cheerful brand, not the last word in security but better than nothing if your bike isn't top range.
NB if you've got an expensive fancy bike, DO NOT use this, bolt croppers can get through it in seconds. Only worth it if you've got a cheap bike.
9mm chain, approx. 115cm long. 3 keys.
Pickup Kings Sutton.
