Rocky Road Fat Tire Ebike Description

The Rocky Road Fat Tire Mountain Bicycle is simply one of the best and most affordable full-suspension electric mountain bike (e-MTB) on the market today. The Rocky Road all-aluminum frame makes is nearly rustproof and perfect for coastal environments.

The Rocky Road features 500W Bafang rear hub motor, which delivers tons of power for hill climbing and towing heavy loads. Its 48V/10.4Ah (17Ah optional) battery is tightly integrated into the downtube part of the frame, providing excellent balance while powering the high torque, zero resistance motor.


The Rocky Road is outfitted with some premium components usually found on much more expensive bikes, including Atlus Shimano 9-Speed gears & shifting System, oversized MOZO Front Hydraulic Suspension & KS Rear Shock Absorber, aluminum rims with quick release axle on the front, a water proof quick disconnect on the rear, and oversized Kenda 26 x 4.0 tires.

Ask a Question
  • What accessories are available for my X-Treme Rocky Road 500W bike? Where can I purchase them?

    X-Treme does not make accessories for the Rocky Road, but you certainly could find some on Amazon or elsewhere. I would consider a good bike helmet, lock and bell as the most important.

  • For the X-Treme Rocky Road: What is the frame size, and what is the minimum seat height from the ground? When will the bike ship? Do you have a date?

    The frame is 18". Max Seat Height = 40.5" Inches / Min Seat Height = 32.5" Inches / Handle Bar Height = 41.75" Inches

  • Hi There, Will you ship to Alaska? If so, what is the approximate shipping fee?

    The ebikes I have shipped to Alaska usually cost an extra $400. But it can vary by brand. I can get a shipping quote. Please send your shipping address to

    Rides Great So Far

    I've been putting my new Rocky Road through a series of off-road tests, and it's performance is very respectable. I am glad I waited to get this model. Hope to start selling some using your ambassador program.

    Great ebikes

    We love our X-Treme Rocky Road 500W 48V/10.4Ah Fat Tire Electric Mountain Bikes! I ride 20 miles a day when I can. They are very sturdy great looking bikes. When we need the extra power for the hills it is amazing. The bikes are also very comfortable.
