Why this is the answer
The correct answer in the official bank: Bicycle traffic crossing ahead.
A red-bordered triangle is a warning sign, and the bicycle symbol warns that cyclists may cross the road ahead. Slow down, watch carefully and be ready to stop. It does not mark a bicycle path, which is shown by a round sign, and it is not about motorised two-wheelers.
