I'll right I'm wanting to get back into riding since I quit when I got into atv's and dirt bikes. Bike would be just for rec use and trail riding mainly. I have random days off work sometimes during the week, and would like to just go out by myself and ride for fun when everyone else is busy and get some exercise. Could also be used to pack/bowhunt in a large conservation area. I'm sure I can learn to wrench on my own bikes, as I'm pretty handy with mechanical things.
1.Would like to stay cheap for now and upgrade as I see fit.
2. I'm 6-1 and about 150, so I need a bigger bike but light as possible.
3. I'm looking at 3 bikes mainly.
Option 1&2 are walmart 29ers cheaper components obviously, but I'm not brand specific, and can upgrade when needed.

3rd Option is an Older GT xcr4000 I-drive I've found used. Not sure on the year. Guy was older and didn't use it much looked too be in very good shape. He said less than 50 miles, and paid 700+ for it back when) Tires still had some nips on them and were flat from sitting for the last 6-7 years. Has an upgraded "man" seat, and a little pack on the bars. $250
My concern with the gt is it is a med size frame and I'm not sure it would fit me, seller was 5-10 and said it fit him. I didn't know what to look for when I looked at it so I just took a pic and started researching. I've also read the i-drive is not really self serviceable should I run into troubles with it. Also not sure I need a full susp bike for my needs, and if bikes are like atvs or moto's the susp is set up for someone around 170-190 lbs not my skinny self. So would I have to have it set up for my weight (more $$). Flat black (good if Itake it hunting) and has the cool factor for me the the full susp, but I want to ride not stare at it, or kill myself trying to ride.

Option 4 Look for another used bike.
Any input welcome
Thanks Aaron
