I could probably write a book about this.

First, a little about me. I have been selling on the Internet for many years. I have a yacht brokerage where I take me own photos and do my own web site, I was a Power Seller on eBay and I routinely sell items on Craigslist, eBay and on my own web sites. I have made tens of thousands of dollars with my camera.

Rule #1. If you want top dollar for any item, it must be clean and shiny.
I can see from all your photos, your bikes are not.
A brass wire brush, an old toothbrush and McGuire's Medium Cut Cleaner work wonders on most metals.
Don't forget the clean towel for a sparkling shine.

Rule #2. If it's broke, fix it.
Nobody wants to pay top dollar for anything that needs work.
Your Trek is a nice bike but, one of the shifters does not match the other. No wonder you're not even getting any bites.

Rule #3: Lot's of very nice, highly detailed pictures.
This takes a certain amount of skill. Good photographic practices and a good camera.

Rule #4: Lots of information.
What's the year of your Trek? If it's in the ad, I missed it and that means it's not there.
Do your homework here. What diffirentiates your offering with the hundreds of other bikes on Craigslist?
Why would I buy your bike?

Rule #5: Find the right price.
Determine the "broom" price. That's the price that a guy, drinking a cup of delicious, hot, fresh brewed Kona coffee will, after reading your ad, put down the cup of delicious coffee and dial your number on the phone. That price will be hard to determine but you have to consider the local market, price history for your model and condition of your offering. Then, add 40% to that price and start there. Adjust your price downward, 10% a week until it reaches the broom price or sells, whichever comes first.

Secret Rule or Rule #6: Keywords.
Place keywords in your ad that will make it pop up in the most searches possible. Remember, most people will find your ad through a keyword search on Craigslist. I've sold items that were buried two weeks deep in Craigslist because people find my ads through keyword searches.

Rule #7: If you can't do ALL of the above, just set the price low and get rid of the stuff or donate it for the tax deduction. Despite popular belief, some things NEVER sell.

As an example, I sold this bike in exactly 1 (that's right, one) day, for exactly my asking price of $200.00 on Craigslist. I had about $100 into it:
