I currently use Citibike and am happy with it. However, if I ever considered purchasing an EUC instead of a bike it's because I wouldn't have to park it and thus making my trips door-to-door rather than having to stop by wherever the bike is parked. I would be able to bring it with me, whether I'm going upstairs into my office or grocery shopping (as long as they have a collapsible handle.)

I think I am more persuaded by the EUC than by the electric scooter because of its speed and maneuverability? I'm not sure, but it seems to have similar problems as the bike.
