So the interesting thing about this is the ... peddle-by-wire drivetrain? So unlike a normal e-bike, when its battery dies it turns into a stationary bike.

I love ebikes and generally like what Rivian does, but in a very competitive market it's hard to see the appeal of this.

When a normal ebike dies you are left with a 50-60lb bike probably not with the gearing you’d want.

Well then the normal ebike should spend another pound to add better gearing.

Once I put myself onto the bike I don't care all that much whether it's 15lb or 50lb.

This is a really dumb thing to say; it makes absolutely no sense. ALso you typically don't "put yourself onto the bike" but rather pedal it.

If you can't figure out what I mean, maybe don't be so confident it's dumb?

I'm not talking about pedaling, I'm talking about sitting. Because now my weight combines with the bike. The difference between 215 and 250 pounds is not that impactful.

Edit: There are some differences in weight distribution, but I clearly don't mind those because they exist while the bike is powered too. The issue at hand is the pedaling, and that depends on total weight.

Reading this back my wording looks a bit contradictory, so to be extra clear: "put yourself onto the bike" is the part that isn't about pedaling. Pedaling comes in later.
