X-Treme Boulderado 48V 17Ah Fat Tire Step-Through Electric Mountain Bicycle 500W Rear Hub Motor 25 mph LiFePO4 Battery

The X-Treme Boulderado 48 Volt 17 Amp Fat Tire Step-Through Electric Mountain Bicycle is a step-through electric mountain bike designed for mixed-terrain riding where electric bicycles are permitted. It uses a 500 W Bafang rear hub motor with pedal assist and variable-speed thumb throttle, powered by an integrated 48 V / 17 Ah LiFePO4 lithium battery.

Manufacturer-stated maximum speed is 25 mph on throttle only. Manufacturer-stated range is up to 150 miles under low pedal assist, flat terrain, light rider weight, and ideal conditions. Actual range varies based on rider weight, terrain, assist level, wind, and riding behavior.

The 6061-T6 aluminum alloy step-through frame supports easier mounting and upright riding posture. Kenda 26 × 4.0-inch fat tires provide traction on sand, snow, gravel, and trail surfaces. A MOZO hydraulic front suspension fork helps absorb bumps, and front and rear Tektro mechanical disc brakes provide controlled stopping. A Shimano Altus 9-speed drivetrain allows manual gearing alongside electric assist.

The integrated 48 V / 17 Ah LiFePO4 battery charges in approximately 3 hours with a UL-certified charger. A King Meter LCD display shows speed, distance, and battery level. The bike includes a rear cargo rack, beverage holder, quick-release wheels, and a snap-on LED headlight accessory.
