One of the first things I did was give the ABS a test. Works great!
Remember your 3 modes plus off. Off is obvious. ABS1 is front wheel only. Allows you to lock rear and flip yourself over the front if you so desire.
ABS2 allows the rear to lift, but my experience was it lifted, lowered, lifted, lowered. Didn't like the feeling as I wasn't in control of the lift.
ABS3 I believe doesn't lift the rear off the ground, haven't tested this one yet.
I stay in ABS1 all the time.
