Unhappy New bike, numb hands!

I hope I'm posting my questioning the right area, however I apologize in advance if this is not right.

Yesterday I broke down and bought a Trek FX 7.4. Yah! Today I took it for a ride and within 20 minutes I noticed my hands and wrists start to go numb. After 30 min I had to stop and take a break. It was quite painful when I got back home.

Someone mentioned that my bike is not adjusted properly. Is there any truth in this? Is there anything I can do to stop this from happening?

You can try raising the handlebars if there's any adjustment left (adding spacers and/or flipping the stem up.) I always get numb hands eventually on hybrids but the way I solved it on my road bike was to slide the seat back. If you're too "bunched up" you'll be supporting more weight with your hands. The goal is to distribute the weight amongst your hands, butt and feet.

I added bar ends to my Trek 7.3 and it helps with the numbness in that I can change hand positions. I've found though that even more important in alleviating this is having my weight better balanced between my hands, butt, and feet so I'm not leaning on my hands as much. As I become a better biker, the numbness issue is getting better as well. I changed to Ergon grips which are great but better weight distribution has more of an impact on numbness than the grips or bar ends, in my opinion.

Agreed. Adjust seat, try bar ends and also try raising the handlebars. If you can't raise them anymore, you can get an adjustable stem. I recently got this one - well built, relatively light, solid, and looks good:

A good pair of gloves solved my hand numbness. I bought the Specialized BG gel gloves for about $25. I also saw that Bell makes some very similar ones that they sell at Walmart for about $15.

I picked the DS8.4 over other brands specifcally for the egon grips that gave somewhere for the heel of you hand to rest on

I would change some of your setting first.
Options to try:
If you are not too concerned with your power stroke, lower your seat post 1/2" at a time until you find a happy medium for power and comfort. Lowering your seatpost allows you to transfer your weight from your upper body to your lower body.
Another easy adjustment is moving your saddle towards the back to bring more weight towards the back of the bike. A shorter stem would also help that, but it also changes the handling and feel of the bike. The main thing i found from having numb hands was loosening my grip on the bars. When i grip too hard my hands get really numb during a ride. Hope this helps.

I brought my bike in to my LBS who adjusted the ergo grips so the palm rests pointed up more, forcing my wrists to be straighter. I took the bike for a ride and my hands felt like they wanted to slide off the handlebars. Lol. Not good. I went back and they removed the ergo grips and put regular grips on, however I haven't been able to try the bike out yet. I did move the seat backwards a bit and noticed that I'm putting very little weight on the bars. I'm hoping the new grips work out!

Well after trying several things, I just couldn't get the bike to a point where I was comfortable riding it. It seems ANY rough patches on the road ( and there are many where I ride) transfers that vibration right up the forks and into my hands making them numb. I switched to a Trek 8.4 DS and LOVE it! So comfy!

I had the same problem when I switched from road bikes to hybrids. And I too solved the problem by adding bar ends. The problem was simply not being able to change hand position.

I've really never understood the appeal of plain flat bars on a hybrid. Seems to me that in general northroad type bars are more comfy, and the flatcar/barend combo gives you the choice of more hand positions. Any thoughts?

Did you change sizes as well as models?

Using Ergon grips and bar ends lessened the hand numbness as did moving the seat back to reduce the pressure I was putting on my wrists. For people who have back pain, a stem spacer may help as will posture breaks and back exercises that may be prescribed by a physician, trainer, or physical therapist. Recreational riding should not be a painful experience.
