Nice bike, good on you

I get that the MFG's are really trying to make most MTB's versatile. They have to climb and descend. The climbing bit is where the chassis design becomes street friendly. So they ride OK on the street, if they are not strict DH bikes. A motor helps, but rolling resistance is not good for either you or the battery ...

All my MTB's have cross purpose tires now. None would be good a actual shredding down a Black Diamond trail anymore. The tires are way to compromised. But they are good on gravel, smaller roots & rocks, and pavement. And since they are now "family" bikes, that's the way they'll stay for the foreseeable ...

The combo on the Hardrock Sport (Schwalbe Marathon up front, Fat Frank out back) is really good on most surfaces. Not great in mud, or slippery wet leaves, etc. But short of that, they work pretty well on most everything. And they are not hard to pump on the street when aired up

The other bikes are a bit less able all around, but still good. It's a bit of a hunt to find the best compromise with only one set of wheels... If two sets of wheels, you can have dedicated street tires that roll easy, and dedicated "country" tires that do trails really well
