I currently have an older Dahon Mariner with a Telescope seat post. The third wheel that functions as the "third leg" (when the bike is folded) has broken off. To compensate, could I switch out the telescope seat post with a longer seat post. When the seat is dropped for folding, my intention is that the length of this seat post will resume the function of this third leg.
Is this possible?
My model does have a hole in the frame's bottom, allowing a long seat post to pass through (and function as a stand).
Update: Thank you for all the comments below. I am still looking to do this and now have the measurements of the current Telescope seat post. They are 34.2mm and 28.x respectively. The bike does have a small plastic shim between the frame and the bottom telescope seat post pole.
Update: It was able to do it.
