Is it a responsibility to hurt property by cycling on the pedestrian street?

Mainly depends on who caused the infringement.

If the property service is not in place, resulting in a fall, the property must be responsible.

Rain is a weather condition, so it is hard to say if it is force majeure. The property shall be provided with warning signs.

Some pedestrian streets are not allowed to ride bicycles, so be careful to be asked.

I hope to give you a reference.
