Seven years ago, or whenever it was, after a decade of fibromyalgia and inactivity, I started riding again by using an e-bike. They are not scooters. They're bikes. The motor kicks in when the sensor receives a certain amount of pressure denoting increased effort, like going up a hill. You still have to pedal and you still have to work, even when the assist kicks in. You ride them just like bikes and follow all the same rules. It helped me get back into shape to ride a bike-bike. Why would you have "serious concerns" about an e-bike rider's approach to safety?
