The Sport version of the GT Sensor Bike comes with a MicroSHIFT Advent X 10-speed drivetrain. This includes a cassette that has a hill-crushing 11-48T gear range that makes climbing and pedaling through difficult terrain much easier. Tektro M275 hydraulic disc brakes provide reliable stopping power so you can descend under control. WTB aluminum rims are paired with WTB Breakout Comp tires that provide excellent traction in various terrain. With the TranzX Dropper Post, you'll be able to quickly lift and lower your saddle with the press of a lever.

How easy gearing is has nothing to do with how many speeds, rather...how easy the gearing is. Speeds regulate how big the steps between cogs are, but again, Sram Eagle are no better than the Advent X at the really low gears, as the jump to the "granny" 50 or 52 is up from a 42T or 36-42‐5xT in all cases, much like the Microshift goes 34-40-48T. So even having more speeds, doesn't really guarantee a more consistent cadence, at least not @ the really hard gears...you have to look into it vs. declaring "10 = bad, sarcasm".
At the end of the day, going a smaller chainring on the Microshift (say a 30 down from a 32) will give you easier gearing (eg 30/48 = .625) that is really close to 32/52 and easier than 32/51T (but again, too close to matter if all you care is the low gear to make it easy going up).
Absolute beginners are in for a hard workout regardless of gearing. And reality is, with bikes you can always exhaust yourself: it doesn't get easier with time, just faster.

This is is however better than currently available FS bikes at a similar price point. The GT is a much better suspension design than for example the Giant Stance 2 or the Polygon Siskiu D7.
Don't do it. If the standover is that low, the reach will probably be too long resulting in discomfort and poor handling. Plus, it might be a danger in jumping off on uneven ground. Regardless of pricing, it's a bad deal if it doesn't fit properly.
With this frame and price, I can take my time customizing/upgrading bits if needed.
Thanks to all for the advice.
XD would be a more difficult upgrade unless the freehub is available for the OEM wheelset, which is hit or miss on most bikes in this price range.
