As in everything American, if some is good, a lot is much better. The power keeps going up on the electric motor bicycles. The top speed, which must be important, is one of the first lines in advertisements. This will become dangerous very soon. People that cannot ride at higher speeds probably should not ride at higher speeds. Where is this continuing increase in power and speed going to end? Crashes. Complain about cyclist speeding on trails and roads, but they are very strong young men and women with some older men and women mixed in that have kept their bodies in great shape. These people are strong and can handle the speed. People that NEED an electric motor powered bike are mostly not strong enough to handle bikes at speed like these cyclists that are in great shape. Big problems will happen.
