Electric bike shares

Maybe it's because I live in San Francisco, but every time I hear about a new electric bike I wish that bike shares used them. This time it's the Copenhagen Wheel, which actually seems better as a retrofit because everything is contained within the back wheel.

A great part about these electric bikes is that they act just like a normal bike, except way easier to pedal. And the docks for these bikes seem like an elegant way to handle charging, no cord to forget to plug in. 

The zero marginal cost model of an unlimited subscription is certainly enticing because it makes it that much easier to grab a bike for a trip that might not feel worth the cost of a Lyft.
