I have an Ortlieb Handlebar Bag similar to this:

But mine is, I think, an older version without the new locking mechanism. And I know why the locking mechanism was added.

Without the locking mechanism, the magnets are so weak that the lid pops open with the greatest of ease making it very difficult to carry and transport.

Given that I really don't want to get yet another handlebar bag, I'd like to come up with a solution for this one.



A couple ideas I've had so far include:

-- figuring out how to add some sort of locking mechanism, which might involve boring holes to add clips or something ... but that might take away from the waterproofness of the bag.

-- finding or making a very lightweight, zippered bag I could line the handlebar bag with, and which would contain my stuff so things don't spill out everywhere. I could then also leave the handlebar bag on the bicycle and take my stuff with me in this liner bag.


But I am definitely open to other ideas.
