I agree with
@stevenast, no rush, LOTS of test rides and consider buying a demo unit or good used ebike as a way to get a better bike but pay what your budget can afford. Thus, the need to test ride, so you're real clear on what style of bike works for you. In the frame batteries don't distribute the weight any better than a down tube battery does, although they do have a classy look, so don't limit your selections. It is better to have the weight of the battery & motor distributed instead of all in the rear and mid drive motors are great with torque/hill climbing and make fixing flats no different than on a regular bike.
Court has many reviews of different styles of ebikes with both written info and very nice youtube videos to give a more 'real' view of a person pedaling each bike on the
home page. He breaks the reviews into different categories of bike style (like mountain/city, etc) and drive style (like hub motor/mid drive motor) that way you can browse some of each before test riding, so that you have some familiarity with various product. The specs, performance and prices that he describes may go a long way to help you narrow what you think you want
Its amazing the amount of choices there are!
Also, perhaps you are mixing the Prodeco Tech Outlaw SS together with the Dillenger Stealth (which btw is a conversion using a Bafang 8fun system, which you can buy online). The Prodeco Tech Genesis v5 with the frame mount battery is supposed to be released this spring but is not available yet.
