Urtopia Carbon Atom 750W Carbon Step-Through E-Bike

Urtopia's first 750W carbon e-bike Long-range power in a carbon step-through frame The Urtopia Carbon Atom combines a Toray carbon fiber step-through frame with a 750W rear hub motor, 90Nm of torque and a removable 835Wh LG battery. Built for commuting, hills, errands and recreational all-road riding, it adds front and seatpost suspension without the bulk of a typical high-power utility e-bike.

Actual range varies with terrain, speed, temperature, rider and cargo weight, tire pressure and assist level. Responsive electric assistance 750W power with a natural torque-sensor feel The torque sensor measures pedaling force and delivers assistance in proportion to your effort. This creates smoother, more predictable support than the abrupt on-off response associated with many cadence-sensor e-bikes. The 48V rear hub motor is rated at 750W, reaches up to 1,250W peak output and supplies 90Nm of torque for hill starts, loaded errands and longer commutes. Four pedal-assist levels Throttle assistance up to 20 mph 20 mph default top speed Up to 28 mph when unlocked where permitted Long-range removable battery 835Wh capacity for fewer charging stops The removable LG M58 lithium-ion battery provides 835Wh of capacity and a manufacturer-estimated range of up to 95 miles in favorable conditions. A complete charge takes approximately four hours with the included 48V 4.5A charger. Battery certified to UL 2271 Charges on or off the bike Approximately four-hour full charge Suitable for long commutes and weekend routes Carbon step-through construction Easy access with a lighter utility-bike feel The sculpted carbon fiber frame provides a low 17-inch standover height for easier mounting and dismounting. At 58 lb without accessories, the Carbon Atom remains substantial enough for utility riding while weighing less than many similarly powered large-battery commuter e-bikes. Suspension comfort for streets, gravel and everyday riding An 80mm suspension fork with lockout helps absorb potholes, broken pavement and light trail impacts. A 30mm suspension seatpost adds another layer of vibration control before bumps reach the rider. 80mm suspension fork Improves control and comfort on rough streets, gravel paths and uneven recreational trails. 30mm suspension seatpost Reduces vibration at the saddle during longer rides and over imperfect surfaces. 26 × 2.4-inch Kenda tires Wide puncture-resistant tires add stability, traction and cushioning. Visibility and braking Hydraulic disc brakes and integrated signaling TEKTRO hydraulic disc brakes deliver progressive stopping control for daily traffic, wet conditions and heavier loads. The lighting system includes a 100-lux front light and an integrated rear light with brake-light and turn-signal functions.
