1. Product Description The Urtopia Carbon Joy Ultra E-Bike is a lightweight fat-tire electric bike designed for urban commuting, daily travel, and weekend leisure rides. It features a carbon fiber frame and fork, reducing overall weight while maintaining strength, making it easier to push, carry, and park in daily use. The 20" × 3.0" Kenda fat tires provide enhanced grip and stability, making the bike suitable for city roads, park paths, neighborhood streets, seaside roads, and lightly uneven surfaces. Powered by a 500W rear hub motor with a peak output of 750W and 60Nm torque, this e-bike delivers strong assistance for starts, climbing, cruising, and light cargo riding. The torque sensor intelligently matches pedal assistance based on the rider’s pedaling force, creating a more natural and smooth riding experience.
