A. Any person engaging in the business of renting, leasing, or loaning (e.g., "test ride") any bicycle or cycle not powered by motor for use in any public area shall offer to the person(s) renting, leasing, or using such bicycle(s) or cycle(s) not powered by motor with the rental, lease, or use of the bicycle(s), or cycle(s) not powered by motor, a helmet, and further shall notify such persons of the requirements under this chapter to wear a helmet. Such persons or organizations engaged in the business of renting, leasing, or loaning bicycles or cycles not powered by motor shall not be required to assess whether or not a helmet provided by the person renting, leasing, or using the bicycle or cycle not powered by motor, meets the standards set pursuant to this chapter.

B. The rental, lease, or loan documents (contract, agreement, brochure, or receipt) of any person engaging in the business of renting, leasing, or loaning any bicycle or cycle not powered by motor in the city of Aberdeen must advise the person renting, leasing, or using the bicycle or cycle not powered by motor of the helmet requirement of this chapter.

C. It is an affirmative defense to a violation of this section for a person wearing an unapproved helmet that the helmet was furnished in conjunction with his or her rental, lease, or use of a bicycle or cycle not powered by motor by a person or organization engaged in the business of renting, leasing, or loaning bicycles, and that the helmet was fastened securely while bicycling.
