Open Thread: Electric and Motorized Bicycles

A post today on Streetsblog New York raises the question of whether electric bicycles should be allowed in New York City. They are currently prohibited from using roadways under New York state law, which has apparently led to people riding (driving?) them on sidewalks.

Neither California nor the City of San Diego places any legal restrictions on where motorized bicycles may operate, but state law does limit their speed and power output, and prescribes specific safety measures that must be taken.

Bike San Diego would like to know what you think about electric and/or motorized bicycles. Aside from the vague notion that they may constitute “cheating” when climbing hills, let’s discuss their virtues or drawbacks as a mode of transportation. What sorts of safety concerns do these machines raise? Should special licensing or training be required? What obligations do the operators of electric/motorized bicycles have towards other motorized and non-motorized traffic? Are there types of roadways or separated bicycle infrastructure on which these vehicles should be prohibited? Any specific experiences, good or bad, with electric or motorized bicycles?

Talk, talk…
