Abus and Kryptonite folding locks are a better go-to than a U-lock. They offer good security and can be attached to a wider variety of objects than a U-lock. Perhaps consider a chain-loop-style lock, especially if you've got panniers on the bike. Chains are the easiest to use when locking up your bike and can offer some very secure locking systems. If you don't use a pannier or bike bag, folding locks often have the best holders, which mount where you'd normally put your water bottle. They usually include a way to attach the holder to a part of the frame without mounting bolts, if that makes sense. For anyone planning a cycling trip along the coast,
