KERN - SolarMoov

The KERN multi-purpose trailer

From €839*

* Excluding postage

FOR DAILY USE OR WHEN ROAMING -->

With 120 litres of interior capacity, the KERN allows you to carry your daily groceries (including heavy items such as several water packs) and is an excellent alternative to the cargo bike. Of course, it can also hold all the camping equipment for a family outing or a long expedition

EVOLUTIONARY-->

The longitudinal central edge of the hull ensures greater solidity, making the trailer self-supporting (patent pending), and also allows the attachment of all types of interfaces: drawbar, solar panel, roof bars, central stand, rear wheel. The 20" wheel also allows more stability and a wide range of tires, including FAT-type tires. Other upgrade options are to come!

FOR ALL TYPES OF CYCLES -->

Thanks to an asymmetrical drawbar and several adjustment positions on the hull, the trailer adapts to all types of bicycles (upright, recumbent, trike, etc.) and all wheel sizes (20"-29"). An adaptation to the thru-axles increasingly present on high-end bikes is also possible (optional)

WATERPROOF AND SECURE -->

- The KERN is waterproof and is equipped as standard with a key quarter-turn lock - A reflective safety flag with the SolarMoov logo is also available as an option (2 colors). It is equipped with a 2-piece carbon rod that can be mounted without tools, and allows it to be stored in the trailer.

FOR EXPEDITIONS -->

Thanks to the materials used, the Kern makes it possible to carry out expeditions or itinerant trips of several months. The shell is made of high-density recyclable PE that can withstand extreme temperatures and UV rays. The kickstand and drawbar are made of ultra-resistant Chromoly steel, which absorbs vibrations

EASILY TRANSPORTABLE -->

All the elements (drawbar, flag, 20" wheel, and possibly stand) fit into the hull of the trailer, and the assembly can be transformed into a suitcase thanks to the small integrated wheels and the front handle

Kern, a concentrate of innovations!

An optimized hull design to ensure strength and lightness

Several innovations with patents and drawings filed: the 120-liter trunk of the Kern is self-supporting thanks to its longitudinal 'backbone' (fig. 1 and 2), which makes it possible to stiffen the hull and fix all the interfaces (wheels, drawbar, roof bar, etc ...). Additional ribs on the top and bottom faces and slotted holes in the column also help to reinforce the trailer. These innovations allow for a relatively thin 'skin' and thus limit the weight: it is about 6kg for the hull without the equipment. The self-supporting structure combined with a 20" wheel also absorbs shocks well while riding and a rear shock absorber is therefore not necessary.

The material of the trunk is HDPE and is resistant to UV and extreme temperatures. The shell is lightly granulated by micro-blasting to limit the sight of possible scratches during use. The latter can also be erased if they are superficial by light heating.at the damaged place(e.g. with a hairdryer): be careful not to overheat as this could deform the shell!

Many bike attachment options

Two bike attachment systems: the only trailer on the market to offer this flexibility

Attaching the trailer to the rear wheel axle of the bicycle is not always possible (for example when the axle is too wide). Conversely, certain configurations are not compatible with attachment to the seat post (trikes, luggage placed on luggage racks, etc.). You can opt for one or the other bindings. If you have several bikes with different configurations, you can also buy the other type of drawbar individually from our store and interchange the drawbars according to your needs (disassembly/reassembly in less than 10 minutes)

Compatibility with most wheel sizes on your bike

Thanks to the asymmetrical and reversible configuration of the drawbar (Fig3) and possible height adjustments at the hull level (Fig2), the trailer can be attached to the bike for a majority of wheel sizes (from 20″ to 29″) with ground clearance parallel to the road. These possible adjustments also ensure the proper holding of the trailer's double stand to support the trailer and bicycle.

A mounting solution for the majority of bicycle wheel axles

If you choose a trailer hook by the rear wheel axle of the bike, you can replace your standard quick-release thru-axle with our fastening system (Fig 5a and 5b), to be screwed onto the axle with a 15 mm spanner. The Kern axle can then be left permanently on the bike, with or without the trailer.

Case of non-standard axles (high-end bicycle, wheel motors, speed hubs, etc.):

If your bike is equipped with a thru axle with a diameter 12mm larger than the standard axles, a specific SolarMoov 12mm axle kit can be purchased as an option (Fig. 6). Adjustment washers are provided to adapt to the majority of axle lengths. 3 types of thread to choose from (1mm, 1.5mm and 1.75mm). Please note this solution is compatible with an original axle length less than or equal to at 180mm.

If your bicycle is equipped with a fixed axle, particularly for wheel motors andgeared hubs, optional adapters are provided.For wheel motors: 2 adapters available for 12mm and 14mm axles. For thespeed hubs, two adapters available:axle diameter M10 (compatible withRohloff, Enviolo, Shimano Nexave, SRAM I-Motion, and SRAM Torpedo) or axle diameter 3/8 26 (compatible withShimano Nexus, Shimano Alfine)

Screwed by bicycle without tools or with tamper-proof screws

The trailer can be attached to the bicycle by tool-free tightening handles (Fig. 7), or by tamper-proof screws (with screw bit provided) to secure the Bicycle/Trailer assembly from theft (Fig. 8). The 2 screwing systems are included and can be interchanged according to needs.

A notch system allows the bike to be easily positioned on the trailer drawbar and makes screwing easier.

A swan neck drawbar for bikes with wheel axles that are too wide

The swan neck drawbar (Fig. 9)is also adjustable in height on the trailer and the attachment to the seat post (Fig. 10) adapts to the majority of post diameters (27.2mm, 30.9mm and 31.6mm). The drawbar is made of reinforced 25CD4S steel (used in aeronautics and motorsport)

A possible transformation into a solar trailer with the Solar Mounting Kit

The trailer is designed to accommodate a solar panel that can be tilted to +/- 45° and thus allows you to recharge your electric bike or other equipment (PC, drone, cameras, etc.) during trips.

We offer in the shop a basic kit of fixings of a solar panel to the KERN trailer, allowing everyone to mount their own tilting panel for a maximum area of 0.75m2. The panel will have to be mounted on a standard 40x20mm aluminium profile (visible in Figs 11 & 13).

If you are interested in a solar trailer assembled by us (including the fixings, the solar panel, the panel base, the solar charger and the appropriate connectors), please contact us.

We have solutions that adapt to most bikes via MPPT solar chargers (for Bafang, Bosch, Brose, Décathlon batteries) or through portable stations such as Ecoflow for other brands.

An Ultimate solution with the KERN_Ecoflow handset to recharge everything

SolarMoov and Ecoflow are teaming up to create a charging solution suitable for all situations.

The tilting solar panel allows you to recharge the Ecoflow River2 station which acts as a buffer battery (256Wh) and charge regulator, delivering a voltage suitable for all devices: 220V to directly connect the charger of your electric bike or your laptop, USB/USB C sockets for smartphones, drones, cameras and a 12V socket for other devices (cool box, etc.).

Scalable rear wheel attachments for FAT tires, disc brakes, wheel motors and other accessories...

We have designed scalable rear wheel attachments (dropout – Fig 14) to accommodate a 20″ wheel, larger than the majority of trailers on the market. The advantage is on the one hand better handling on rough roads and on the other hand the possibility of easily finding technical tires adapted to difficult conditions.

The trailer is also compatible with a 4″ wide FAT wheel (Fig. 15 – wide rim required soon on sale in the store),a disc brake (disc attachment present on spoked and spoked wheels) or a wheel motor.

Additional holes are also provided for hanging various equipment: signaling flag, mudguards, lighting.

A transformation into a suitcase during transport

The 'wheel axle' drawbar and the 20″ wheel can be stored in the trunk of the trailer in addition to your personal belongings (Fig. 16).

The handle and small integrated wheels allow the trailer to be rolled like a suitcase, making transport by train or plane easier (Fig. 17).

Roof bars for transporting bulky objects

Aluminum roof bars covered in EVA foam allow you to transport a surfboard, a box or any other bulky object.

The oblong holes located all around the trailer allow you to insert straps to hold bulky objects on the roof bars.

A SolarMoov security flag

A safety flag with the SolarMoov logo is available in the shop. It can be dismantled for easy storage in the trunk of the KERN trailer. Both tubes are made of carbon and the pennant can be installed on the trailer quickly without tools. The logo is reflective. 2 colors are available: yellow and orange
