X-Treme Rocky Road Fat Tire Electric Mountain Bike



The Rocky Road fat tire mountain bike provides a fast, smooth ride for rocky terrain. The over-sized MOZO front hydraulic suspension and fat Kenda 26x4.0 tires provide cushioning and shock absorption while the 48-volt battery and 500-watt Bafang clutch motor with it's digital torque sensor gets you over those difficult hills.

This ebike comes with everything aluminum (down to every bolt, nut, nipple, and spoke) to keep it looking gorgeous and rust-free. 

The 100% hand welded lightweight aluminum frame bicycle has Atlus Shimano 9-Speed Gears & Shifting System to allow you to pedal manually when the motor is turned off.

The aluminum rims feature a quick-release axle on the front as well as a waterproof quick disconnect on the rear.

The Rocky Road comes equipped with the King Meter 5 Speed Smart Power Assist System (SPAS) with a USB phone charging port so you can stay connected on the go.

The electronics of this X-Treme ebike are controlled via rider input on the LCD screen that is 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 ebike 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 Rocky Road is one of X-Treme's fastest ebikes. It has been tested climbing a 5-7% mountain grade continuously for 45 minutes at 18 mph while having to slow down for hairpin turns.

Front & rear Tektro disk brakes are standard to give you fast stopping power along with true VELO brand hand grips & mountain bike seat for a durable and comfortable fit.

X-Treme offers an optional 6-month extended warranty in addition to their standard 1-year warranty. Just select that option before adding to cart.

This electric mountain bike comes standard with a high- quality beverage holder at no extra charge! This is a one of kind bike that you are sure to love.
