The maps: I use my android phone to record the route with a free app: Move! Bike Computer. The app can export to .kml files which I open in Google Earth. In Google Earth you can show the elevation profile of the .kml file. Once you have the elevation profile up, click File > Save > Save Image... and it will take a nice screen shot of what ever you have up on the Google Earth viewer. It is a nice little way of outlining (roughly) trips via mileage and elevation. One thing to note: it is only as good as your device's GPS. So far though, it has been the best (and cheapest) way to keep tabs on my trips.
As far as the wheels go: I did not build them myself. I worked with the LBS owner here in Connecticut to chose parts and he built them up for me. I do not have the technical know-how nor the tools to build up a set of wheels.
tl;dr:

Self-built: Nope.
I picked it up last week and spent some time over the the weekend cleaning, polishing, ceramic coating, and swapping on a set of OneUp pedals. Now I just need it to warm up outside so that I can go ride the trails. I'd like to eventually remove the tubes and set the wheels up tubeless. Does anyone have any suggestions for valve stems? Looks like there are a few options for anodized blue ones on Amazon. I like the looks of these: https://www.amazon.com/Tubeless-Presta-Valve-Stem-Remover/dp/B07TQFXTMD And why would I want longer valves? Seems like the longer ones would just leave more change to catch on something and get damaged.
Congrats! Wonderful bike, I have this exact bike. I highly recommend getting these pedals because the stock pedals are hard plastic that are like butter when they get wet. Also if you plan on hitting rock gardens and/dirt jumps, I would highly recommend getting this rear derailleur. I found out the hard way when I hit a jump and my chain slapped, thankfully I did not wipe out. ALSO convert to tubeless! I haven't yet, but I am planning to in the near future.
Most important part, ENJOY THE BIKE AND RIDE RIDE RIDE!!
My new seat was a huge improvement from the rock that was on it standard. I'm using this right now and it has made a world of difference on my long rides.
I don't think you have clearance for a true 29er tire. This is the closest thing you might be able to run (but it's possible that it's still too wide). Look for aggressive cyclocross tires.
I assume it is the Tioga Spyder Twin Tail Race Saddle. From my research you have to change it out every now and again, because the material tends to break. It is very light however and apparently more comfortable than you would think.
geax gato 29x2.3" the rolling resistance is a little higher but they do way better offroad. cheapest place i found them http://www.amazon.com/gp/product/B003RLCC46/ref=oh_details_o04_s00_i00?ie=UTF8&psc=1
I'm 6'4", and about 310 lbs and haven't ridden in years, so yeah, I feel ya. I bought this bike back in February, and I love it. I ended up buying a more comfortable saddle (MTB seats apparently aren't made for sitting?) and this stem riser to raise the handlebars to a more comfortable height. I don't really do any trail riding, but it's nice to have a bike that fits, that can stand up to my weight, and can handle curbs, potholes, tourists, and other road hazards. I'm still getting a feel for what this bike can do and how to do it, but so far it's stood up to my fat ass riding it. I'm sure that it's considered an "entry level" MTB, but for folks operating on a budget like us, I think it's a great bike.
Be prepared to spend a few hours putting it together, and probably a trip or two to the store for a 17mm open-end wrench for the pedals (adjustable wrench is too thick) and a 6mm Allen wrench for a bunch of other stuff. Some Presta-to Schrader valve adapters and a tire guage for Presta valves will come in handy too. I'm on long-term business travel in Key West (rough life, I know) and didn't have any metric tools with me, and had never had a bike with Presta valve stems before. My brother had them on a racer, so I knew what they were, but they delayed my first ride by a couple days.
this helps wrist support, but just like brimley is saying, don't lock your arms. keep them loose, and have a firm but not tight grip.
