Urtopia Carbon Classic Step-Thru E-Bike

Elegant Design. Aerospace Performance. Effortless Access.

The Carbon Classic Step-Thru (ST) combines Urtopia’s world-class carbon fiber engineering with a convenient, easy-entry frame. Weighing in at an incredible 38 lbs, it is one of the lightest e-bikes in its class. This is the perfect choice for riders who want a sophisticated, high-tech commuter that is as easy to mount as it is to ride.

Ultra-Lightweight Carbon Construction

Unlike heavy aluminum bikes, the Carbon Classic ST features both a carbon fiber frame and a carbon fiber fork. This aerospace-grade material doesn’t just reduce weight—it naturally absorbs road vibrations, providing a smoother, more refined ride without the need for heavy suspension systems.

Powerful & Intuitive Performance

The heart of the Carbon Classic ST is a 750W Peak rear hub motor delivering 60Nm of torque. Paired with a high-precision torque sensor, the motor measures your pedaling force and matches it instantly. The result is a ride that feels natural and athletic, providing assistance that works with you, not against you.
