Curt

Ampler was founded in 2014 in Tallinn by Ardo Kaurit and Rait Udumäe — engineering-led Estonians frustrated that e-bikes looked clunky and obviously electric. Their answer was a stealth aesthetic: a 250 W rear hub motor and a 336 Wh battery hidden inside the down tube, so the bike reads as a normal urban cycle from three metres away. The Curt is Ampler's performance flagship — the lightest model in the lineup at 14.1 kg, designed for riders who want assistance without admitting they have it. Every Curt is hand-welded and assembled in Estonia, motor-calibrated and ride-tested before shipping. In 2024 Ampler made the Curt the world's first USB-C-chargeable e-bike — a small but symbolic gesture: charge with the same cable as your phone. The company filed for bankruptcy in early 2026 over a Berlin showroom lease dispute, but the brand and production continue under Kõu Mobility Group ownership (acquired 2023). For URBALT, the Curt represents the Baltic engineering ethos at its most refined: clarity, restraint, and the conviction that good design disappears.
