New stock - latest 2019 model with many upgrades.
One of the only Full Suspension Fat Tire eBikes on the market. X-Treme is way ahead of the competition.
As if riding a fat tire bike was not already the most fun you can have on 2 wheels, add a beefy 500 Watt Zero Resistance gear rear hub motor (if you choose to ride without power you won't feel the resistance of the motor when pedaling) with Digital Torque Sensor and full suspension, and you have the Ultimate Fat Tire eBike.

This bike is so smooth, you will never have to get out of the saddle again, so that means more control and more fun. Packed with top quality name brand components, this bike is built tough and built to last.
This is a one of kind bike.

This bike features a lightweight, compact lithium LiFePo4 48 volt 10.4 Ah integrated battery pack providing a considerable amount of power. 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 miles per charge (*depends on rider weight and terrain). The 100% hand welded lightweight aluminum frame bicycle has Atlus Shimano 9-Speed gears & shifting system, oversized MOZO front hydraulic suspension & KS rear shock suspension, aluminum rims with quick release axle on the front and a waterproof quick disconnect on the rear and oversized Kenda 26 x 4.0 tires.
Equipped with 5 Speed Smart Power Assist System (PAS) with a USB phone charging port. You control the electronics on the LCD screen. Smart PAS with 5 speeds will enable the bike to operate nearly twice as efficient as a non-smart assist e-bike, which will allow your Rocky Road to possibly reach or exceed 40+ miles per charge. The LCD also indicates speed, distance, and battery life.
Front & rear Tetko disc brakes are standard along with true VELO brand hand grips & mountain bike seat.

Three ways to ride the X-Treme Rocky Road 500W 48V Fat Tire Full Suspension eBike
- Pedal only (with no help from the motor)
- Pedal Assist (with 5 levels of assist to choose from)
- Throttle only (effortless like a motorcycle)
The X-Treme Rocky Road can be used as a normal bike where the rider provides all the power, or you can use just the throttle and let the bike do all of the work. There is also an in-between option, Pedal Assist, where the rider pedals and the motor provides a great boost at the same time. You can choose the level that is right for your type of riding. It makes riding fun and effortless.
