X-Treme Rocky Road 48 Volt 500W Fat Tire Full Suspension Electric Mountain Bicycle


 The Rocky Road 48 Volt 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 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.   We now offer the option to purchase an upgrade to your Rocky Road to ship with a 48 Volt 17 Ah Lithium LiPo4 which allows for an increased 60-65% distance.    This means you can get up to an additional 115 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 48 Volt to possibly reach or get as far as 70+ 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.


Rear Rack Sold Separately For The Rocky Road   

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 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.

fantastic fat tire bike

I spent a month researching, testing, and reading reviews of all the different fat tire ebikes on the market, and there is a reason this one is usually ranked so extremely. The motor is excellent and extremely powerful, and the pedal assist feels far superior to most others I've tried—the Rocky Road is far more enjoyable!!


A powerful bike that can support a motor of up to 500 watts... and has a top speed of 30mph with pedal assist. Riding with my friends is a lot of fun...

awesome ride...

I ride my super fat Rocky Road and it's a lot of fun and ideal for beach riding. Awesome!

happy with my purcahse

The best e-bike I've ever seen! Great battery life; you'll be able to go a long time on a single charge. For city streets and off-road riding, this is an excellent choice. This bike is fantastic. The company provides helpful, polite, and prompt customer service. I am pleased with it and would recommend it to others.

This is the best bike I've ever ridden.

Our X-Treme Rocky Road 500W 48V/10.4Ah Fat Tire Electric Mountain Bikes are one of our favorites! When I have the opportunity, I cycle 15 miles per day. They are powerful and attractive bicycles. It's fantastic when we need the extra power for the hills. The bikes are also really comfy to ride. This bike is well worth the money!!!
