Personally, we’ve never heard of a case where people rent bikes in Vang Vieng and after had problems. For example, because it was alleged that the bicycles were damaged and that a repair is necessary. Such scams are not uncommon in Asia. In Vang Vieng, however, we’ve never experienced anything comparable. Besides, we don’t know anyone who has it. So you shouldn’t have any trouble. However, if you’ve had a bad experience, please leave us a comment. We and our readers would like to hear more about it.
