With children returning to school and the city of San Diego's new electric bike ordinance about to take effect, health and safety experts Friday took the opportunity to warn parents about the dangers of e-bikes. Because of that, the city of San Diego is following others in the region by enacting e-bike rules. “These regulations were carefully crafted to promote education-first enforcement, allowing us to put children’s safety first while ensuring older youth still have access to safe, affordable transportation options.” “Parents need to teach their children safety rules as well as the rules of the road,” Dr. Ignacio said. Under the new ordinance, parents can also be held liable for their children’s violations.
