My commuter is an elderly and rather tatty 90's MTB whose main job is to sit at the tram stop all day withough being nicked. It runs as sweet as can be, just looks old.
Just to be sure it is double locked, although that's with a supermarket special that looks more solid than it actually is on the front wheel/frame/rack, backed up with a 10€ combi lock through back wheel/frame/bike rack.
A couple of days ago the Supermarket special jammed, fortunately after unlocking it from the bike, so until this morning the bike had a couple of days with only a cable lock. Seriously, anyone with a decent set of wire cutters could have been be one bike better off.
I'm still not sure if I should be pleased that it hasn't been nicked, or affronted. I guess if I'm being honest, it's trying to be unattractive and awkward to remove, so people will nick the flashy hardtail next to it instead, but still...
Either way it now has a rather better lock running through frame/front wheel/bike rack, and I'm pretty sure I'll be able to cycle back from the tram stop tonight...
