Hi and welcome,

It's never too soon to start looking for a bike that better suits your needs. The Trek Pilots are road bikes with a more upright position than a "traditional" road bike. It's a great, high quality starter bike and the price is good (I think it's about $200 off list). The most important thing with a bike is fit; it should feel right. Be sure to try more than one size if possible. Also, try other bikes, even if you think this is the bike for you; you might find something that suits you better, or it will help reassure you that you made the right decision.

As far as butt comfort, most of us end up switching out the saddle that comes with the bike for something else. There are whole sections on these boards for saddles in the Gear and Accessories part. One size/type definitely does not suit all.

Take care,

Nicole
