Power source battery

The Fafrees FF20 Polar sets itself apart with a dual battery system, two independent 48V 10.4Ah batteries combine for 998Wh of total energy and up to 140km of range in pedal assist mode. A dual-battery equalizer balances output across both cells, reducing wear and extending overall battery lifespan significantly compared to single-battery rivals.

A 65Nm geared hub motor, 20x4.0 inch fat tyres for snow, sand and gravel, and a fold-in-30-seconds frame make it equally practical for long-distance commuting, weekend adventures and compact everyday storage.
