"Electric bicycles are typically two to three times the mass of non-electric bicycles, and this extra mass is additive to the body weight of the rider"
An average mountain bike is 30 lbs. An average e-mtb is about 50 lbs. That's not 2 to 3 times the weight.
Someone needs to inform the writer how many people are killed by cars every year. Personally, if given the choice, I'd rather have an old guy crash into me with an e-bike rather than a car.
