Hello, I have one ebike. 500w 3x7 speed, 26" folding design. Retired engineer, first time appartment dweller. Space and large initial outlays of money are a consideration. I could tell you all the noble, righteous, and fitness motivations for choosing this activity, yes I could. Shamefully I might say that I'm intrigued by taking a 20 mph ride in the open air. The reader is invited to choose. I have a life long habit of buying an entry level hobby item and making continuous improvement a principle element of the hobby. I anticipate asking for help and advice as I travel along this journey.
