It depends how you are going use it. If you are doing any off road riding, defiantly go for a full suspension bike to even out the bumps. With the ease of an ebike you can do longer runs, and a full suspension bike will be a lot more comfortable.
I got a Trek Powerfly+ FS7 with the 500Ah Battery, I love it, its a great bike, good spec, and not to bad to ride with no assistance.
I also tested a Giant full sus, and the Trek Hardtail, and a couple of Haibikes, Very pleased with my purchase, I think I made the correct choice, as I do a reasonable amount of off road riding, but not major downhills, jumps etc.
