Electric Power Assistance

The Custom Specialized Li-Ion battery features a powerful 500Wh or 700Wh capacity for maximum range and trail riding pleasure. It features a protective rock guard with an integrated handle for easy removal. Next to the charge port are four integrated LEDs that display the charge status while charging.

Battery anxiety? Not on the SL bicycles. Our compact and discreet SL Range-Extender Battery provides up to 40 additional miles of mountain-flattening power to complement the up to 80 miles of range from the Turbo SL’s internal battery. More range, more riding.
