Reddit reviews M-Wave Amsterdam Hard Box

Funny, I just asked myself the same question today, with a very similar use-case (leaving the bike lights in a locked container on the bike while running).

I was thinking of a small hard-case that would have a metal ring or something so that I could put my U-lock through it. That way it wouldn't need to be locked to the bike when the bike isn't locked.

Haven't looked too hard yet, but lockable hard cases for racks definitely exist. I don't know how they are secured to the rack itself, but you could always take a cable lock to secure the box to the bike.

Some I came across on a quick search:

• Pletscher EasyFix Hard Case
  
• M-Wave Amsterdam
  
• Rixen & Kaul KlickFix Bike Box for Racktime
  
  Edit: OK, not really road bike containers, sorry for misreading your question. I leave the comment here anyway.
  
  Edit 2: This thing from PacSafe might work... found via relevant thread on Stackexchange.

Or if you already have a backback you can go for the oldschool option(i.e. mil crate with zip ties):

All of these items should have amazon free shipping(two days for prime, 6-8 for non prime members but still free)

If you are worried about showing up unwrinkled. Perhaps something like [This](M-Wave Amsterdam Hard Box https://www.amazon.com/dp/B001EVAYFK/ref=cm_sw_r_cp_apa_i_gT8XCbWS15V8F) hardcase would suit you better then panniers.

This should work:

You can get a lockable box for your rear rack like this one (Amazon Link), your helmet should fit inside but of course check first.
