I weigh 180, my bike 50 or so pounds, and rarely, if ever, use PAS level greater than three (of nine) on BBS02-equipped hardtail (52V, 10 ah battery). Doubt you would have any problems. Initially you might use a higher level, but that would decrease as your fitness improved. My wife (115 with 50 or so pound bike) and a grandmother never goes above level one (of five) on the hardtail that I built for her.
