Thanks, I think that may ring a bell, not certain. I'd only heard of it briefly back in the day, never researched, looking on wiki now, it's much different than I expected, I thought would look like dirt bike, it looks more like oversize mini-bike, with hugely wide tires.

Now, with electric, piece of cake to do that. If fact, I've wondered about front-motor e-bikes like a Brompton, how much advantage that would be, if climbing on soft soil, to power the front while pedaling the rear. Granted, a bike with just the rider and no front cargo, the front will probably be a good deal unloaded and less traction, if going up a steep hill. But a touring-loaded bike, that could help.
