Not just electric bikes, but also electric skateboards and other electric personal mobility devices. Unlike bikes these things can be brought on public transit, and greatly reduce time spent on the last mile (or two). For example the boosted board can travel 25 MPH, which is much faster than rush hour traffic, and even at times the grade-seperated light rail in San Francisco.
