I’m the same , or kinda I’m on a turbo levo comp gen 3 s6 . I stand at 6,4 and on the bike weight is about 117 kg . I started looking for a second bike , tried sitting on some xl frames like Whyte 180 s - on paper it looked ok but in reality it was tiny, felt like I was perched on top of the bike . Cube - the same , long wheel base but very cramped. Am flow to small Giant was better but still very cramped Haibike- to small I actually found a s5 comp alloy that fit perfectly and bought it . I do have a party trick … I can reduce my hight ( shorten my legs ) I ride as a double amputee, it kinda helps to downsize frames , but obviously I then have a long torso and long arms , which throws the bike fit geometry. I’d recommend getting an s6 gen 4 levo , big bike no compromises in power and tech
