Thanks MaCie' for the comments. 1. Not a major infrastructure, but a modular design with each module at size of 50*50*70cm 2. Safety of the property: the module will come with mechanical design that allows people to lock e-bike/e-scooter onto. It also comes with authentication capability that could prevent unauthorized removal of e-bike/e-scooter. 3. Cost of access: the idea is to have business and city to sponsor the setup and operation of the hubs, so out of pocket cost for use to use the basic parking and charging services.
