A bicycle trailer to always have with you

Trenux – a trailer that you can take with you anywhere and anytime without limiting the flexibility of your bike.

An innovative folding mechanism allows carriers and trailers to be combined in one product. In contrast to bulky load bikes and space-restricted bicycle bags, Trenux offers the right transport option in every situation: whether it’s the big week’s shopping, searching for a parking space at a bicycle stand or a barbecue evening by the lake. The luggage carrier folds open to become a load trailer in a matter of seconds. The trailer is immediately ready for use and can be stowed away again as a luggage carrier in no time at all after transport.


For unfolding, the unfolding handle is used after opening the locks. Several mechanical interlocks give the trailer increased stability and prevent it from wobbling. When the Trenux is no longer needed, the folding handle in the middle of the loading area is pulled and the trailer collapses.

Loading area

Folded out, the trailer offers space for two beverage crates, a travel case or four flower boxes. The charge is kept stable by the trapezoidal frame and the bands. Additional tension belts fix light transport material.
Load capacity: 40 kg (note max. speed)
Load space: 62 x 42 cm
Standard: Eurosize Container


A pocket completely integrated into the folding mechanism forms the rectangular loading area. Two beverage crates can easily be stowed here. Due to the water-repellent material, the bag can be pulled out upwards when it rains and the transported goods remain dry inside. In the supermarket, the bag can be removed from the trailer and used directly for shopping. In addition to the colour combinations, reflectors round off the design.

Dimensions: 60 x 40 x 30 cm
Colours marine, summer


The drawbar of the Trenux is fixed on the axis of the rear wheel. The standard mount is compatible with a full axle and quick release. This allows us to cover the majority of bicycles. In addition, a holder on the saddle tube is required to be able to fold Trenux.

Compatibility: full axis, quick-release
Alternative: Connection to frame tubes

Would you like to test directly whether Trenux also fits your bike?

Here you will find instructions and a template to print, with which you can check it directly!


The drawbar can be mounted and removed in seconds using the quick release mechanism. To make sure it stays your Trenux, you can lock it keyless by simply pressing two locks.

The standard mount is simply screwed onto the quick-release or the full axle.

If the standard mount on your bike does not fit, there is an alternative for the frame.

The seat tube mount is also suitable for spring-loaded saddles. https://youtu.be/l5-yT5jsFVo?t=25=25


According to the StVO, the trailer is equipped with reflectors, additional reflectors are also on the bag. Tension straps can be attached to a suspension to secure the load. In the event of a fall, the trailer remains stationary due to the special coupling joint, poses no danger. During development, we have oriented ourselves to the corresponding DIN EN 15918.


Trenux can be used as an independent luggage carrier or in combination with an existing one. A luggage carrier may be present, but is not required. In this way a Trenux really does fit on every bicycle. Like a conventional luggage carrier, Trenux is fixed at three points: To the left and right of the axle, and on the seat post.

Bearing weight: 7.5 kg (depending on configuration)
Baggage carrier width: 35 cm
Trailer width: 60 cm


In the event that the trailer is used without a bicycle, there is a trolley extension. This is additionally mountable and can be folded out easily and quickly.

Here you can make a non-binding reservation for a Trenux from the next series.


Can children be transported in Trenux?
To ensure that nothing happens to children in an accident, a roll cage must be attached to a trailer. However, we have not yet finished developing the foldable roll cage. If Trenux continues to prove itself so well for non-living loads, development for living loads will soon also be tackled.
Do bicycle trailers have to be certified?
The TÜV, as it exists for cars in Germany, is not available for trailers. However, there is a DIN standard on safety requirements for bicycle trailers (DIN EN 15918). During the development of Trenux we orientate ourselves on this.
Does Trenux fit on every bicycle?
We haven’t found a bike Trenux doesn’t fit on yet. On bicycles with a low saddle and a saddle that is moved forward, the carrier surface is slightly tilted. If you think Trenux will not fit on your bike, let us know and we will try it out. Bicycle racks are designed according to standards that we take into account during development. If you can fit a standard carrier, Trenux might do so, too.

Can carrier bags be attached?
We are in the process of integrating a carrier bag holder. In the morning on the way to the office the laptop does not have to be in the trailer but can comfortably be carried in the bag. Two bags will not work.
