I'm a fairly old codger, but still above the ground. Very interested in finding the right ebike. I have crummy knees. I'm 6' tall and about 220 these days. My inseam is 29". I'm looking at the Aventor Aventura stepthrough and wondering which frame might suit me best. No place around here for a trial. Mostly will ride on decent trails, mostly paved, but some probably not. Mild hills. Would like to know how much the Aventura battery and compartment weighs, and any other knowledge and advice that might be given. Thanks!
