Curt: a Design Icon Reborn. Ampler’s Lightest E-Bike, Now with USB-C Charging
28 October 2025, Tallinn, Estonia – Ampler, the Estonian e-bike manufacturer known for its beautifully minimalistic, lightweight, and hand-built electric bikes, unveils the next evolution of its design icon: Curt.
After years of refinement, Curt returns as Ampler’s most accomplished and lightest model to date, now featuring USB-C frame charging, a new carbon fork, two drivetrain options, upgraded electronics, and the most advanced internal architecture the company has ever built.
The Art of Timeless Design
Light, fast, and unmistakably elegant, Curt has always embodied the purest expression of Ampler’s philosophy: form follows function.
Inspired by Bauhaus design principles, Curt is more than a mode of transport. It’s a showcase in proportion and purpose. Every line, weld, and surface is intentional; every detail exists for a reason.
It’s an object that bridges art and utility, made not to be admired behind glass, but to be lived with. Curt glides through the city with precision and quiet confidence, featherlight to lift and effortless to ride, even without power.
Its natural balance means you can pedal it like a regular bike, yet with the added ease of silent electric support whenever you choose. The assistance builds seamlessly, turning every commute into a subtle daily workout. Riders can fine-tune assist levels through the Ampler app to match their rhythm, from a light boost to full electric ease.
Minimal in form yet rich in feel, Curt moves with instinctive precision: light to handle, agile in traffic, responsive through corners, and immediate in its power.
Perfection, Hidden in Plain Sight
Beneath Curt’s clean silhouette lies a completely renewed foundation – the result of Ampler’s most ambitious engineering work to date.
The new USB-C frame charging system is the centrepiece of this evolution, the first of its kind in the e-bike world. One universal cable powers your laptop, phone, and now your bike. No bulky charger, no clutter, just intelligent design that makes everyday life simpler. And with 140 W fast-charge capability, Curt reaches a full charge in just 2.5 hours, ready when you are.
The battery system has been reengineered with state-of-the-art cells for greater longevity, higher reliability, and consistent performance. Yet the real transformation lies deeper within: a new electronics core, fully developed by Ampler’s in-house engineers.
This core, the brain of every Curt, represents one of Ampler’s proudest advancements. The ABC module integrates Bluetooth, GPS, and cellular connectivity with built-in smart diagnostics, into a single waterproof system that ensures stable, silent performance in every condition.
Every Curt is tested to withstand thousands of kilometres of vibration, rain, and real-world use. The result is an e-bike that’s smarter, stronger, and more dependable than ever. Backed by a four-year warranty that reflects to Ampler’s confidence in its craft.
Lighter in Build. Broader in Choice.
Starting at just 14.1 kg, Curt is the lightest e-bike Ampler has ever built. Its double-butted aluminium frame, seamless welds, and balanced geometry create a ride that feels both solid and weightless.
A new lightweight carbon fork with an enhanced layup absorbs vibration for smoother handling and a more responsive feel, adding refinement you can sense with every turn.
Riders can choose between a Single-Speed Gates Carbon belt drive for simplicity or an 11-speed Shimano drivetrain for more control. Both are powered by a 250 W rear-hub motor with 45 Nm torque and a 336 Wh LG Li-ion battery, delivering up to 100 km of range, depending on terrain and assist mode.
The frame is now kickstand-ready, enabling two configurations that reflect different ways of owning simplicity. The Blank version leaves the essentials beautifully untouched – no fenders, carrier, or kickstand by default – giving riders the freedom to add only what fits their taste and routine. It’s a bike designed to be personal, not prescriptive. The Equipped model, meanwhile, brings everyday practicality straight out of the box, with pre-installed accessories for those who prefer ready-made convenience.
“Curt is the purest expression of our design philosophy,” says Eva Raigo, CEO of Ampler. “Every element has a purpose. Nothing more, nothing less. With this update, we’ve taken something iconic and refined it for today’s world. It’s the same Curt, simply perfected.”
