Stolen bikes

And since Ed's very careful himself with seat security, I'd imagine he'd taken the time to ensure his girlfriend's bike has the same level of care.

yup, ball bearing + superglue.

thought no one bother to nick the brooks bag, they just look inside it and also it's superglued to stop people from undoing the strap to take it off.

not exactly completely anti-theft, but just enough to make the other bike seemed easier to get, and most especially since CSM student bike tend to be expensive bike and cheap lock (like a brand new pashley with a cheap £10 colourful lock to keep it safe).
