Is it possible to replace a bike seat and post?

Our daughter has a K2-Bayside '05 bike (SKU #716-179-0022). Someone stole the seat and seat post and we would like to replace them. She no longer lives near us, so we are not able to measure it for her. If it is possible to get the size of the seat post, that would be appreciated.

Thanks for reaching out and we're sorry to hear about your daughter's bike seatpost and seat. The size of the seat post you asking about is 27.2mm. Just an FYI, 27.2mm is a fairly standard diameter for adult bike seat posts.

Hopefully this helps!
