Curt

13.5 - 14.3 kg70 km range

Raw. Fast. Untamed.

Ampler Curt is a fast-moving and bold city charger that’s stripped of all excess, only keeping that which is key to a fierce ride. The stiff frame, full-carbon fork and straight handlebars give Curt an athletic look and keep the weight low: the single-speed e-bike with belt drive weighs only 13.5 kg and the 10-speed version weighs 14.3 kg. The Ampler Curt offers you the agility you need in everyday life. Riding it feels firm and highly responsive – just like with a racing bike.

Available as a 10-speed or singlespeed e-bike

The Curt is available in 10-speed configuration or as a singlespeed electric bicycle with belt drive — you can choose the version that best fits your needs for versatility and looks. The singlespeed version has the Gates belt drive that keeps Curt’s drivetrain clean, quiet and almost maintenance-free. The 10-speed version of the Curt e-bike has the Shimano Deore M6000 shifter and derailleur which lets you climb even the steepest hills.

Designed for the city streets

The Curt electric bike is equipped with lightweight mudguards that keep you dry on rainy days. The puncture-protected tires from Continental offer you peace-of-mind on any road, and you’ll stay visible to others with the bright integrated light set. The resulting e-bike is as sleek as ever while giving you the flexibility to ride in all weather conditions, everywhere.
