Dont quote me on this but if you were to cut it off you would have to source a seatpost that would fit in it as i think its an odd size i,e, not a 25.4 or a 30.1 like some of them. They built the zoot with out a seat post in mind so i think the actual seat post its self in the frame is a little smaller than a normal seat post. + If you were to run a seat post in it you would have to cut out some gap holes for the seat tube to flex to keep your seat post in place.
I apologise to you i was on here and facebook at the same time and got pissed off and confused, soz for that you can call me all the names under the sun
