X-Treme E-Bikes Owner's manual

*Order NOW while stock lasts. We offer free and safe shipping for all our electric bicycles*

The Rocky Road comes equipped with the King Meter 5 Speed Smart Power Assist System (SPAS) with a USB Phone Charging Port. The electronics of the X-Treme Electric Bicycle are controller via rider input on the LCD screen attached to the handlebars. Smart PAS with 5 speeds will enable the bike to operate nearly twice as efficiently as a non-smart assist e-bike because you select the power consumption (speed controls 1-5 setting) on the LCD during your ride. This feature will allow your Rocky Road 48 Volt to possibly reach or exceed 70+ miles per charge when using low SPAS while always pedal assisting on flat ground under perfect conditions with a lightweight rider. The LCD also indicates Speed, Distance, and Battery Life.
