Most ebikes are like cruiser bikes, even if they have 150+mm travel forks. Their chainstays are long and they're heavy, not easy to manhandle esp if they have a long wheelbase.
You're going to likely want to keep a short wheelbase bike w/short chainstay around for fun.
There's a short list of ebikes that ride like a legit dialed mountain bike: like a Rocky Mtn Altitude Powerplay, Pivot Shuttle, Lapierre eZesty, Canyon Spectral:On, Fezzari Wire Peak, Vitus E-Sommet, YT Decoy... these *might* allow you to ditch your bicycles, but variety is the spice of life.
P.S. if you're between M and L, upsize to L. You may be tempted to downsize to make it more "agile", but any manual/wheelie that you pop will come straight back down, since the front-heavy weight bias is too great. It's counter-intuitive, but I recommend getting the larger size, esp for the Wire Peak, E-Sommet, and Decoy. Heck, go XL on these 3 if you can. You will be able to hit drops without even doing much to keep it level, due to the longer front end and the speed and stability it allows. Also, consider a -2d angleset, longer fork, and 29er front...
