The World’s Smartest Lightweight Step-Thru

The Urtopia Carbon 1 Step-Thru is a masterpiece of "connected" mobility. Weighing a remarkable 36 lbs thanks to its aerospace-grade Toray carbon fiber frame and fork, this bike is as easy to carry up a flight of stairs as it is to navigate through dense city traffic. The elegant step-thru design offers a 18.77-inch standover height, making it the perfect choice for riders seeking accessibility without sacrificing cutting-edge style.

Beyond its featherweight build, the Carbon 1 ST is a "bike-shaped smart device." Featuring the Urtopia Smartbar, this e-bike integrates 4G, GPS, and Bluetooth directly into the handlebars. With fingerprint unlocking, voice commands, and on-board navigation, you can leave your phone in your pocket and immerse yourself fully in the ride.
