The city is proposing a long-overdue bike-helmet law that would make wearing a helmet mandatory for all cyclists. This law will help protect cyclists of all ages from potential injury.

Yet new helmets are lightweight and designed with air vents so you will not overheat while wearing one. In conclusion, a bike-helmet law would help make biking safer and, by extension, more enjoyable.
