Bike theft
Bike theft is a serious problem in the Netherlands, especially around train stations, and in larger cities. If possible, use the guarded bike parking ('stalling') at train stations and in some city centres. They will cost up to €1.25 per day. In general,
use 2 locks of different kinds (for example, one chain lock and one tube lock). This is because most bike thieves specialize in a particular kind of lock, or carry equipment best suited to one kind of lock.
Unsafe parts of cities In the larger cities, certain areas are considered unsafe at night. A few are also unsafe in daylight (but only relatively so; the chances of you getting in trouble in one of these areas are still very small):
