High-quality equipment

The Rocky Road comes standard with a 48V 10 Ah Lithium LiPo4 battery.   We now offer the option to purchase an upgrade to your Rocky Road to ship with a 48V 17 Ah Lithium LiPo4 which allows for an increased 60-65% distance.    This means you can get up to an additional 115 miles per charge (*depends on rider weight and terrain).

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 efficient 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 bike 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.

The Rocky Road is faster than any model that X-Treme sells.  It has been tested climbing a 5-7% mountain grade continuously for 45 minutes while having to slow down for hairpin turns.

Front & rear Tektro disk brakes are standard on the Rocky Road ebike along with true VELO Brand Hand Grips & Mountain Bike Seat.

The 48 Volt Rocky Road 10Ah Fat Tire Mountain Bicycle now comes standard with a rear cargo rack and aluminum front & rear fenders at no additional cost. 

This electric mountain bicycle comes standard with a high-quality beverage holder. There is no extra charge!  This is a one of kind bike.  No other brands offer a Full Suspension Fat Tire Bike, only X-Treme!
