On one of the first test rides I did on an emtb, I dropped down a steep cutting onto an old railbed. I knew that the walk feature existed on emtbs, or thought I did. I had never used it on any e-bike. The bike was a rather heavy CUBE and I could NOT get the walk feature to activate, nor even find the word WALK anywhere. The side of the embankment was too steep and loose for me to push the bike up, certainly too much so for me to ride up. I thought I was going to have to ride several miles along the railbed just to get out. It was made of old aggregate, so 1.5"-2" lumps in size and no fun to ride (I was still in mtb mindset!) Eventually I used the pedals as crampons and see-sawed the bike up the embankment. My shoes were not gripping on the loose soil either which made the whole effort just that, an effort! I was knackered by the time I got to the top. First job when I gave the bike back was to get a walk demo.
