I went through on one of the budget airlines from UK to Germany with a full size Krypto U-Lock, handlebars, and a dozen smaller sharper objects before. All in hand luggage no problem.
However to be totally safe, see if you can get the Bahn instead of flying.
That said the were so easy-going in Schoenefeld a few weeks ago, I carried glass bottles (empty) and loads of stuff, they didn't bother to search me or even ask for liquids to be taken out the wash bag.
