I traded in the OneX 29" at Walmart for the Genisis GX7.
Dropped it off at LBS for the packing and tunning.
Has anyone else had any experience with this bike?

I have one. Mine came with v-brakes/linear pull brakes while the recent ones have caliper brakes (really cheap construction with no/limited upgrade potential). Had a set of Shimano Deore brakes laying around and put those on along with salmon pads and the braking is really good now.
Surprisingly very light and fun to ride. Overall balance of the bike makes the front end light and is more geared for those that want to do wheelies/tricks rather than grocery/hauling duties. Handlebars are a bit too wide for my taste and may not squeeze thru narrower spaces or share a path/bike rack w/o hogging a lot of real estate.
Dont know how durable/long lasting the frame or fork will be. Changed mine to a 1x10 cargo/grocery hauler and may change the handlebars to a regular cruiser size one. Also sold the 48h wheelset and got a deal on a Velocity Chukker wheelset with Shimano hubs. Really dont think the stock rims were made for rim brakes use anyways. Running Schwalbe Big Apples. Oh yeah, the seatpost broke within a week and brought a $20 micro-adjust one at the LBS. Had to buy the Tiagra flatbar 10-speed shifters so I could use any of the derailleurs I had laying around and the stock derailleur w/o having to go the full dyna-sys or sram route.
I wanted a rigid 29'er to fool around with and am pretty happy how the project turned out.
