Can I replace the seat with a wider, thicker seat? If so, what is the diameter of the seat post?

The context confirms you can replace the seat on the FREESKY Rocky, as long as the seat post is properly adjusted and not extended beyond the minimum insertion mark. However, the diameter of the seat post is not provided in the context.

I just ordered a Rocky Pro from Amazon. Several months ago I purchased a Wildcat Pro on Amazon, too. I just found that I am unable to get any more questions answered about the Wildcat from my Amazon account. Can i write to you about questions or problems I might have with either ebike? thanks
