We take a cover on our bike holidays, it folds up small but it’s not a full sized one and leaves the pots and below exposed, however it serves 2 purposes.
1. It helps keep the sun and rain off the bike if it’s left out in the pavement at the accommodation.
2. It helps hide the ‘attractiveness’ of the bike. We’ve been sat within sight of the bike on occasions whilst having a drink or dinner, without the cover people stop and look, but with the cover on they just pass on by, it really is quite a marked difference. I’m not saying dedicated thieves will do the same but every little helps.
Otherwise it’s a Roadlok, Litelock X1, BMW disc lock and the alarm… the balance between what you can reasonably take on a 2-up trip and acceptable security.
Not forgetting Wapping’s lb of butter of course!
