Urtopia Carbon Classic ST Step-Through Electric Bike

Lightweight carbon step-through ebike with a natural, bicycle-first ride feel.

The Urtopia Carbon Classic ST takes everything that makes the Carbon Classic appealing — light weight, clean design, smooth pedal assist — and adds a step-through carbon frame for easier mounting and everyday comfort.

It’s built for riders who want a light, easy-to-handle ebike without jumping to a heavy cruiser or utility platform. The result is a bike that still feels nimble and efficient, just more approachable to get on and off.
