As the this photos shows, there are all sorts of bicycles today. Big ones and little ones. This is a the smallest bicycle I have seen so far. Also, interestingly this bicycle is electric. I assume the primary benefit is the bicycle is that it can be stored in small places like the trunk of a car or in the an apartment.
Following is a link to a Bolt Pro Electric mini bicycle which looks very similar the bicycle in today’s photo. Also, following is a link to the today’s photo saved on Flickr with the caption: A mini e-bike seen in uptown Charlotte.
