That does sound like a issue. I wonder though are more people are choosing "standard bikes" because of longer free window as you said, or is it that your bikeshare program is choosing to provide more "electrified bikes" because of increased profits or demand?

Personaly I choose the "electrified bike" (i.e. pedel assist) as its easier for me to get around more comfortably and go further distances with less knee pain and strain, but having both options is a plus.

My area has a docked bike program. In a app I can always see how many bikes are available at a designated dock and how many of those bikes are electric vs manual.

Also, a side note the term "e-bike" has become a "catch all term" for electrified two wheel modes of transportation IMO. Most of this used by the media as a negative generalization or buzzword to group e-motos, and e-mopeds together with electric bicycles. This is mainly related to exploding unregulated batteries which generally are caused by e-mopeds, not electrified bicycles. This is why I generally in conversations try to make a distinction between bicycles, mopeds, and motorcycles, when they are electrified.
