Looks like a great bike.
Hope I'm not teaching Granny to suck eggs, but with an EMTB you need to be mechanically sympathetic when changing gear, easing off the pedal pressure slightly when shifting between cogs for a smooth shift. Try not to shift 'under load'.
If you don't you will be replacing chains and sprockets at pretty short intervals as the assistance from the motor will chomp through the teeth profiles on the cassette in no time. I did my first rear cassette and chain in about 1300 miles, some folk on E-bike forums have done a lot less.
If you are used to riding analog, you should already have terrain reading skills but the trick is to get into a suitable gear early enough to keep your cadence high, then increase motor assistance if needed mid-climb to maintain momentum, rather than start the climb in too tall a gear and then have to boost the motor first (stretching the chain) and then down-shift under power (chewing up the cassette).
Enjoy the new bike, the Levo is a great piece of kit. I ride a Giant EMTB myself and couldn't go back to an analog MTB now with two knackered knees.
