The Rocky Road 48 Volt Lithium Powered Fat Tire Electric Mountain Bicycle offered by Family Fitness at Home is a Lithium Battery powered Electric Bicycle cranking out 500 Watts from the Bafang High Torque Zero Resistance Clutch Motor.  This electric mountain bicycle features a lightweight, compact lithium LiPo4 48 volt 10.4 Ah integrated battery pack providing a considerable amount of power greater than our 24 volt or 36 volt 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 Hyrdraulic 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.  

The Rocky Road comes standard with a 48 Volt 10 Ah Lithium LiPo4 battery.  


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 Mountain 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 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 light weight rider.  The LCD also indicates Speed, Distance and Battery Life.


The Rocky Road 48 Volt Lithium Powered Electric Mountain Bicycle is faster than any model we sell.  It has been tested climbing a 5-7% mountain grade continuously for 45 minutes at 18 mph while having to slow down for hair pin turns.


Front & rear Tektro disk brakes are standard on the Rocky Road 48 Volt Electric Mountain Bicycle along with true VELO Brand Hand Grips & Mountain Bike Seat.


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!
