NÜWIEL eTrailer FAQ
Everything you need to know
Discover how the NÜWIEL eTrailer works, what makes its patented Zero-Force Sensor Technology unique, and how the electric cargo trailer can transform commercial transport and last-mile logistics.
General Information
The NÜWIEL eTrailer is the world’s smartest electric cargo trailer that makes it possible for anyone to move heavy and bulky goods in a safe, sustainable and easy way.
Powered by a smart electric drive system and patented Zero-Force Sensor Technology, it synchronizes with the bicycle’s movement with millisecond precision.
Unlike conventional trailers, the NÜWIEl eTrailer actively adjusts its acceleration and braking to the bicycle, helping prevent pushing or pulling and delivering a smooth, natural riding experience. It feels like the NÜWIEL eTrailer “disappears” behind you.
It can be attached to conventional bicycles, e-bikes, and cargo bikes. When detached, it can also operate as a powered handcart for transporting goods in pedestrian areas, warehouses, and other indoor environments.
The NÜWIEL eTrailer can be attached to any standard bicycle, cargobike or electric bike and also used as a handcart in pedestrian zones or buildings. It is robust, easy to handle, and ideal for urban last-mile logistics.
The NÜWIEL eTrailer combines patented Zero-Force Sensor Technology with an smart electric drive system that synchronizes acceleration and braking with the bicycle’s movements with millisecond precision.
High-precision Zero-Force Sensor Technology continuously detects changes in movement and enables the system to adjust motor assistance and braking in real time. This helps prevent the eTrailer from pushing the bicycle downhill or creating unnecessary resistance uphill.
The NÜWIEL eTrailer is an intelligent cargo transport solution that combines bicycle-level flexibility with car-like payload capacity. Its unique Handcart Mode enables seamless use across cycling, indoor logistics and pedestrian environments.
Zero-Force Sensor Technology is NÜWIEL’s patented technology for intelligent electric cargo transport. It uses high-precision sensors and software algorithms to detect the movement to synchronize the eTrailer’s movements with a user with millisecond precision.
The system automatically adjusts the acceleration and braking in real time, ensuring no pushing or pulling is felt, whether uphill, downhill, or during braking.
This creates intuitive, controlled riding experience with maximum safety and comfort.

Handcart Mode
Handcart Mode allows the NÜWIEL eTrailer to be moved on foot.
When the eTrailer is detached from the bicycle, the system switches to Handcart Mode and operates under the speed below 6 km/h.
NÜWIEL’s electric drive assists movement at walking pace, completely eliminating the need to push or pull. This makes it easier to move heavy and bulky goods through pedestrian zones, indoors and narrow streets.
The user remains in full control of the eTrailer throughout the use.
In handcart mode, the NÜWIEL eTrailer is limited to a walking speed of 6 km/h, ensuring smooth and safe operation in pedestrian zones, indoors, and festival grounds.
Not at all. The NÜWIEL eTrailer doesn’t need to be pulled. You simply walk with the eTrailer, and it follows you. .
Thanks to our Zero-Force Sensor Technology, the NÜWIEL eTrailer detects your walking pace and adjusts automatically making transporting heavy goods on foot effortless
It feels like walking with a well-trained dog!
You can use the NÜWIEL eTrailer in pedestrian zones, sidewalks, parks, warehouses, buildings, campuses, event areas, and more.
