Urtopia Carbon Joy Ultra Cruiser E-Bike | UL 2849 Ultra-Light Carbon Fiber Electric Bike with Fat Tires
Ultra-Light Carbon Frame – Only 42 lbs
At just 42 lbs, the Carbon Joy Ultra is up to 50% lighter than comparable aluminum electric cruiser bikes. The aerospace-grade monocoque carbon fiber frame delivers exceptional strength while dramatically reducing weight, making it easier to lift, maneuver, and transport. Its ribbon-inspired chainstays and seat-tube-free design create a flowing, sculpted silhouette that stands out wherever you ride.
500W Motor with Instant Torque Sensor Response
The 500W rear hub motor provides smooth acceleration and confident hill climbing. An advanced torque sensor with zero response latency delivers natural pedal assistance that reacts instantly to your effort. Switch easily between thumb throttle and torque-sensing pedal assist for versatile riding across city streets and scenic routes.
All-Day Range – Up to 70 Miles
Powered by a 529.2Wh Samsung lithium-ion battery, the Carbon Joy Ultra delivers up to 70 miles per charge. The removable battery allows convenient indoor charging, while torque-sensor efficiency can extend range compared to cadence-based systems.
Adjustable Cruiser Comfort
Designed for relaxed, all-day riding, the step-through frame allows effortless mounting and dismounting. The adjustable 0–60° cruiser handlebar lets you customize your riding posture from upright comfort to a slightly sportier stance. A wide, shock-absorbing saddle enhances long-distance comfort.
All-Terrain 20” x 3” Fat Tires
Heavy-duty 20” x 3” all-terrain tires provide enhanced traction, shock absorption, and stability on pavement, gravel, and uneven surfaces. Reinforced components and a carbon fork ensure durability and smooth handling wherever your ride takes you.
UL 2849 Certified Safety & Integrated Protection
The Carbon Joy Ultra is UL 2849 certified, meeting rigorous U.S. electrical safety standards for electric bicycles. The 529.2Wh Samsung battery is certified to UL-2271 for additional reliability. Hydraulic 180mm disc brakes provide powerful stopping with automatic motor cut-off for added safety. A rear rack with integrated brake light enhances visibility, and a discreet AirTag mount adds an extra layer of theft protection.
