During a recent visit to China I was impressed to see so many silent motor scooters. Electric motor scooters. I even rode on one.
Now I know why, Time reports that 90% of the world's e-bike sales are in China.
Electric scooters look the same as gas scooters, except for no trail of smoke. They don't sound the same, they're silent. This would be hailed as a great green success if it were happening in London or New York.
