Several kind folks on this forum have suggested I post here as someone may be able to assist me. The short version is that I have acquired a Trek Verve 1 WSD, 13" frame, hybrid bike.

This was selected after visiting 6 local bike shops.

The bike store and my husband have tried repeatedly to get the seat comfortable to no avail. It has been lowered, raised, tilted forward, tilted back and leveled.

Regardless of the position, I consistently feel as if I'm too close to the pedals and keep wanting to sit further back which places pressure on an already damaged tail bone. If I sit centered on the seat and the seat is tilted down in the front, I'm constantly slipping forward, making it difficult to pedal and putting pressure on my arthritic wrists. If the seat is tilted back, then the opposite problem occurs, and I'm holding the handle bars trying not to slip backwards, again making my wrists hurt. When the seat is level, I am again trying to sit further back on the seat to make my legs comfortable but hurting the tail bone.

As for the saddle height, I can just touch the ground with my toes. Any higher and I won't be able to reach the ground at all while on the saddle.

I think I'm looking for a way to move the seat backwards an inch or two. Is there any way to do this to my bike without breaking the bank? A set back seat post was suggested by the bike shop ... But not only am I unable to figure out which one would do what I'm asking, I can't figure out which one would work for my bike and ... what I have seen online seems to run $200 or more.

My husband is very handy, so a DIY solution would be really nice.

Thank you for any suggestions you are able to offer.
