In Pictures: Rivian-backed ALSO TM-B e-bike tested to empty battery, revealing odd 'Infinite Turtle Mode' behavior

The ALSO TM-B's pedal-by-wire drivetrain leaves no mechanical fallback once the battery is drained.

Riders testing the TM-B to zero report progressive power cuts before the software begins shifting unpredictably.

An early owner's range test pushed the Rivian-backed e-bike until the battery was fully depleted.

The experiment underscores how deeply software governs the TM-B's ride feel when charge runs low.

Without a chain connecting pedals to wheel, the TM-B's behavior at empty depends entirely on firmware.

The owner documented erratic simulated gear shifting as the battery approached shutdown.

Battery management proved central to the test, revealing the limits of the TM-B's low-power turtle behavior.

The findings raise questions about what riders can expect from battery-less pedal-by-wire systems.

The 'Infinite Turtle Mode' behavior left the tester with a bike that shifted oddly rather than simply coasting to a stop.
