Thanks for the responses. I do appreciate the input.
The bike is just too too small. I decided to give it one more try. I took it out on the paved bike trails and rode it about an hour and a half. I felt squinched the total trip. I kept wanting to stretch my arms and legs and I found myself many times putting my butt back on the seat as far as I could go. My legs when at down stroke on pedal were maybe 45 degrees and not 8 or 10 or however many they should be. I kept looking at other bikes going by and no one had their knees up on the handle bars like I did. I'm not even sure if extended out 2" would do the trick. I would just be happier with a bike more my size.
Near the end of the trail were a few guys getting ready to hit the trail. I figured since they were just preparing I'd ask their opinion and like myself, they totally agreed. The one guy said that bike is too teenie tiny for you....his words exactly. He showed me the riser on his bike and said he didn't think that would do the trick for me as the bike was too small period. He said my legs looked so cramped. Riding it, I felt like I was a grown-up on a kids bike...it's just too small and I've 100% decided I would prefer one that fit me better....a bigger bike. I just can't imagine a 17" being too big when this 15" is so small. Even bike shop guy said even though it has 15" on it, is looked to be a small 15" bike.
I called Nashbar customer service when I got home and asked what my options were. She said I could return, but I have to pay the shipping. If I exchanged it, they would pay the shipping of the new bike. So that is out of the question. Probably 50.00 for bike shop to tear it back down, 50.00 probably to ship it to Nashbar, 50.00 lost on putting it together and another 50.00 to put new one together. That's 200.00 just to exchange and get the new one. It would be crazy for me to do anything but sell it.
So I'm going to find a nice place to put it in the house and not ride it anymore. It may be months before I'm back out riding again.
Besides Craigslist and Ebay, anyone know any good ways to sell the bike?
