The lightest Ampler
Starting at 14.1 kg with a new carbon fork, Curt is now lighter and more adaptable than ever and amongst one of the lightest e-bikes ever made.
Perfection in Design
Beneath Curt’s modernist frame lies Ampler’s most advanced engineering yet: a new electronics core with smart connectivity, reengineered battery, and rock-solid reliability for years.
USB - C Charging
Curt now features Ampler’s pioneering USB-C frame charging system. The same cable that powers your laptop and phone, now powers your Curt in 2.5 hours.
Fast by instinct
Curt handles like a finely balanced sports car: sharp, responsive, and composed. The lightest in its class, it moves with precision, responding as instinctively as you do.
Born of modernist thinking, Curt transforms simplicity into elegance. Light, fast, and precise, for those who move with intent and appreciate the art of restraint.
