Ah, that would be a nice skill. I might even be better equipped for it now than when I was young because I’ve gotten into roller skating and improved my balance that way.

Kickstand, holding a fence, etc. That active Regen thing sounds great, if I buy one of these I’ll make sure it can do it.

Sure, but there are limits. One needs a certain amount of forward speed to maintain balance easily, and there’s a maximum speed that can be reasonably pedaled. If the hill is steep enough then in my experience reducing the gearing enough to make pedaling not too strenuous runs into the other two limits. If an e-bike can have a low battery topped off before the hill starts, then pedal-assist (at least) would take care of the need to lower the gear while going up it.

Yes, but is it possible to pedal and use regen breaking to recharge the battery when stationary? It does work like that in my car (plug-in hybrid) but I don’t know if e-bikes are the same way.

I don’t own one of these, but that sounds actually useful if for example I’m about to climb a big hill and want to pedal at a less strenuous pace (but for more time) than would be needed to overcome the slope.
