The Bulls, Haibikes, Turbo Levos & Powerflys I've demoed are "more planted" as delivered. Takes more effort on your part to get those tires in the air.
Just add a volume reducer (or 2 if necessary) at both ends & readjust desired sags to get more pop. Just like any other FS Mtb.
Tight uphill switchbacks can be challenging if too-much assist selected. ON-OFF-ON-OFF... assist because of inconsistency in applied pedal torque can create balance & loss-of-traction issues when you don't want them.
My solution is low-enough gear for me with minimal assist. For example, on my Powerfly with Bosch CX, I may be using Sport mode to climb steep stuff, but will drop to Tour or Eco mode before switchbacks so I have better balance & control pedaling thru 'em in bottom gears.
If it can keep you riding or riding MORE ... go for it!
