Electric bikes can be fast and dangerous. Here's how to stay safe

As electric-bike usage has risen, so have e-bike injuries, and regulations in cities and states throughout the country are rapidly changing. Federal law classifies most e-bikes as nonmotorized vehicles, but many states have adopted stricter rules and a three-tier system to classify e-bikes by power and speed. To stay safe on the road, e-bike riders should learn how their e-bike works and its top speed, and follow the most recent regulation in their state regarding helmets, licenses and speed limits. Medical professionals also recommend following common sense rules, like wearing a helmet, using front lights and not biking under the influence.
