That's a couple of chunky locks mind

I like the simplicity of the box section, easy to install, but it will be satan's own to remove, clever.
Servicing, hmmm. I brought my bike MOT forward 'just in case' the weather hangs on and it's not just sitting there, unable to be used. Also, I'm known to do a few miles on crisp, winters days when the salt is on the roads but it's dry and powdery (followed by a phorensic level of washing frenzy when I get home) rather than wet. We get a surprising amount of those in Northumberland so I do get out a bit in the winter. My mate has a fancy phone app which tracks mileage, speed, altitude etc and he reckons March was the biggest month for bike use this year? So, if it were myself, I'd get it seviced sooner rather than later - just in case.
