The 2019 X-Treme Rocky Road Fat Tire Electric Mountain Bike is a 48 volt model for riders who love the look and feel of monster-sized tires. Oversized MOZO® hydraulic forks go a step further to cushion bumps on the trail.
The Rocky Road is part of X-Treme’s 48 volt series of electric bikes and shares much in common with its brothers and sisters. All 48 volt models are built using higher quality materials, components and deliver greater performance.
The X-Treme Rocky Road 48v electric mountain bike is packed with top-of-the-line components like MOZO® hydraulic front forks, KS rear suspension, 500w Bafang® motor, Tektro® disk brakes, advanced LiPo4 battery pack, Shimano® Atlus 9 speed shifter and gears and oversized Kenda® mountain bike tires.
The Bafang 500w motor puts out 200 watts more power than X-Treme’s 24v models. You’ll reach a top speed of 25mph with plenty of torque to take on medium sized hills and mountainous terrain without pedaling. The battery system cranks out 48 volts and will deliver you up to 70 miles when using power assist. The battery pack is easily removable, can be charged remotely and come with a key lock. In manufacturer testing X-Treme 48v ebikes maintained a speed of 18mph on a 5 - 7% mountain grade for 45 minutes!
The Rocky Road is equipt with a King Meter® Smart Power Assist System (SPAS). Flip the switch and the motor delivers power to the rear wheel as you pedal. The amount of power depends on which of the 5 settings you choose. This “smart” power assist system is about twice as efficient as the standard PAS on X-Treme’s 24v ebikes.
The Rocky Road by X-Treme can be powered as follows:
1) Pedal Power Only.
2) Twist And Go (TAG) – Press the variable speed thumb throttle and go! For an extra boost, pedal to pick up the speed.
3) Smart Power Assist System (SPAS) – Activate SPAS and the motor delivers power to the rear wheel while you pedal. Choose from five power assist settings. The higher the setting, the easier it is to pedal. For an extra blast of speed, simply give it throttle or pedal harder.

Still excited about this bike! The tires are so cool, they look amazing, and I can ride this thing pretty much anywhere. It's got a lot of power if you ask me. More bells and whistles than the others I was looking at, too. I've shown it to my friends and they love it as much as I do! So excited to have new adventures with this electric bike.
