Rivian's ALSO TM-B e-bike uses pedal-by-wire technology with 180 Nm motor delivering 0.3g acceleration, but requires power for any movement unlike traditional e-bikes.
But for the front, there’s nothing which appears to sink energy, apart from what appears to be a conventional disc brake.
Maybe it’s like an electric car, which uses a combination of regen, and disc brakes. Depending on the car I think letting off the accelerator (in one-pedal mode) engages regen, while the brake pedal uses the disc brakes, and does not capture energy. Or in some cars the brake pedal uses regen braking for a portion of its travel, and disc braking if you press harder.
Maybe this bike uses regen when you stop pedaling, and has regular disc brake levers for faster stopping? Or maybe regen back-pedaling?
Regenerative braking recovers up to 25% of energy while integrated traction control prevents wheel slip. The TM-B monitors both wheels independently, adjusting power output in fractions of a second to maintain grip.
The only way I can parse this is if “power output” means the regen power. But even so, it explicitly says both wheels, and I can’t figure out how it would do that. Or perhaps “power output” also includes the dissipated heat from friction braking. Truly a strange statement to try to pick apart

The phrasing from the “article” says this:
