Bikes have very efficient transmission systems, so outside of extremes you can pedal at an efficient amount of torque for the rider regardless of say: hitting a big hill. This is doubly so for e-bikes that assist in the pedaling.

This is more akin to a hybrid car, who's gas engine could generate electricity, but in the case of this e-Bike from Rivian, why would you do that? The electric motor is significantly more powerful than a person's legs, outside of the Pro Peleton.

Watch anyone on a Class 3 ebike: they're not pedaling. The bicycle drivetrain is just there to get around regulations, like having a license.

Rivian isn't known for making hyper-efficient electric vehicles. Rivians are MANLY trucks made to do MANLY truck things, like go fast! and go through tires faster!
