Ants infestation on bicycle
The ants don't really have any reason to stay in/on your bike. Worst case, depending on how bad it is, I would wash it down using soapwater. That way if there is any sweet juice or bug parts left to eat and make your bike more attractive to ants, it would no longer be a problem. Good Luck, I hope you can reclaim your bike back from the ants! Next time the ants should buy their own bike... not satisfied with an anthill I guess :-)
