We Are X-treme Electric Bicycles And We Work Non Stop To Make Electric Bicycling Safe, Fun And Most Important, Affordable For All.

The Rocky Road 48V Lithium Powered Electric Fat Tire Mountain Bicycle is a Lithium Battery powered Electric Bicycle cranking out 500 Watts from the Bafang High Torque Zero Resistance Clutch Motor.  This bike features a lightweight, compact lithium LiPo4 48V 10.4 Ah integrated battery pack providing a considerable amount of power greater than our 24V or 36V models.  

This bike comes with everything Aluminum - every bolt, every nut, every nipple, every spoke.  That means no rust!   The 100% hand welded lightweight aluminum frame bicycle has Atlus Shimano 9-Speed Gears & Shifting System, oversized MOZO Front Hydraulic Suspension & KS Rear Shock Suspension, aluminum rims with quick release axle on the front and a water proof quick disconnect on the rear and oversized Kenda 26 x 4.0 tires. 

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!
