My bike always lives in my dining room on a stand for security reasons (along with my sons) and only ever gets used for exercise so therefore never gets left at the shops etc. I'm thinking of taking it on holiday with me to limit the damage holidays do to my weight . While not using it, it would either be stored in the car or in our apartment but I'd still like to lock it up. Can anyone recommend a lock that isn't crazy expensive, everything that's being recommended seems to heading up to the £100 bracket. It's a £400 bike so not massively expensive in general but expensive to me and irreplaceable as it stands. I'm probably going to answer my own question that there is no good cheap lock but thought I'd ask anyway.
