Hello! I am wanting to purchase this bike for my son off of Craigslist. Could someone tell me what year and/or make/model this bike is from Trek?

This link should help.

2014 Trek Jet 20 - BikePedia

It's a kid's bike. Year/model is mostly irrelevant. Condition and size is what matters. I'd go into a bike shop and price out a new Trek kid's bike. Expect to pay maybe half that for a decent used one. Most kids are pretty rough on bikes.

FWIW, Trek will probably not even be able to tell you what year or model it is. I've sent them a couple serial numbers from nice (mystery) road frames from the early 2000s and they said they were unable to identify them...

Thanks Brian! Do you know if Trek will make a bike look a little different than what is pictured for that year? The one I would like to buy looks a bit different.

They change things each year, like color, design, components, etc. That's why bikepedia is such an awesome resource.

Click on the "year" options on the right side of the bikepedia page until you find a year/color that matches.

It's a 2012 Jet 20.

Done.

Thank you Tim! That is just what I needed!
