The frame, wheels, box, etc. should be washed and cleaned regularly to remove dirt. The parts should be wiped with a damp cloth. Avoid dirt in the joints. Check regularly for loose parts and have them tightened by a bicycle dealer if necessary. All visible, moving parts: cables, adjustment screws, moving brake parts (NOT brake discs), chain, pedals, bell, and lock should be lubricated regularly with bicycle oil. Screws, threads, and axles can also benefit from a few drops of oil, and the chain should be tightened if necessary.
