Rivian’s Pedal‑by‑Wire E‑Bike Runs Out of Power, Reveals Unexpected Behavior

Rivian’s new e‑bike, the ALSO TM‑B, eliminates the traditional mechanical link between pedals and rear wheel, relying instead on copper wires to transmit power. In a recent test, a rider drained the bike’s battery to zero, triggering a series of odd responses that the manufacturer has not yet fully explained. The article notes that the TM‑B’s design, while technologically impressive, raises a practical question: what happens when the battery dies? The report documents the rider’s experience and highlights the lack of a mechanical fallback, suggesting that the bike’s performance may become unpredictable without power. Rivian’s approach could set a new standard for e‑bike design, but the incident underscores the need for reliable safety protocols when the electrical system fails.
