I am slightly wider and have no problems at all, it is super comfortable even after hours. Just try it out and if it's not comfortable, just send it back. But I'm convinced that as long as you're under the specified weight, it should fit well.

The seat (fabric) is approx. 48-50 cm wide. The bars are added on the left and right. The stated 60 cm refers at most to the back area. As you sit slightly below the bars, it is quite possible that the bars could press on the sides.
However, as nobody knows your build, nobody can answer this with certainty. I myself have slightly wider hips, but I can still manage quite well.
