Witnesses in Kristianstad said the bees swarmed around the parked bike in Sodertorg square after apparently abandoning their old hive, The Local reported Tuesday.
"Then the queen arrived and they started to come in droves after that," witness Jan Ekdala told the local Kristianstadbladet newspaper.
"In only five minutes it was a gigantic bee-swarm," Ekdala said.
Experts said bees will often choose a gathering place, such as a tree branch, after abandoning a hive while waiting for about 20-50 scouts to find a new permanent home.
