Yes, bike helmets are generally considered safe and effective in reducing the risk of head injuries during cycling. Studies have shown that wearing a properly fitted helmet can decrease the likelihood of serious head injuries by up to 70%. Helmets are designed to absorb impact and protect the skull and brain in case of accidents. However, the effectiveness can be influenced by factors such as helmet design, fit, and cycling habits. It's also important to note that while helmets significantly enhance safety, they do not eliminate the risk of accidents. Riders should also follow safety practices like obeying traffic rules and being aware of their surroundings. Overall, wearing a helmet is a critical safety measure for cyclists of all ages.

The answer is well-structured and provides a comprehensive overview of the safety aspects of bike helmets. It highlights the significant reduction in head injury risk, which is supported by research. The mention of factors influencing effectiveness, such as design and fit, adds depth to the response. However, it could be improved by elaborating on the specific types of injuries that helmets are designed to mitigate, such as concussions or skull fractures. Additionally, while the answer briefly mentions other safety practices, it could be expanded to emphasize the importance of a holistic approach to cycling safety, including visibility, road awareness, and regular helmet maintenance.
