DoggyTourer Weber EL / ES Coupling System

The loads - versions of the E-clutch. Only suitable for cargo trailers, up to a train load of 80 or 100 kg.

The Weber E-coupling was developed with the aim of suiting every wheel. It is mounted by the patented polygon fastening system, twist-proof on the axle of the rear wheel.

Due to the various forms of bicycle failing and gear versions, our couplings do not generally fit all bicycles. Commonly thicker special polygons are needed for quick-release axles, special polygons for hub switching or the replacement plug axle X12.

For safety reasons, a belt with metal clasp must be used when using the E-coupling, starting from year. In 2017, be mounted on the drawbar.

Scope of delivery: 1 EL coupling or ES coupling, 1 insert, 3 standard polygon inserts (for quick clamping with 2.5 mm and 5.5 mm thickness and for full axes), installation instructions.

The EL coupling (up to 80 kg pull load) and ES coupling (up to 100 kg pull load), are exclusively for cargo trailers, only when connected to full or thru axle!).

Due to the various forms of bicycle failing and gear versions, our couplings do not generally fit all bicycles.

Special polygons are required for some sporty bicycles and hub gears. These can be found under accessory coupling systems! Longer quick-release axle axles are often required.

Version E is one of the most sold bicycle couplings on the market. In addition to thousands of times proven safety, the reason for this is above all the unbeatable ease of use thanks to the patented bayonet closure system.

The Weber E-coupling was developed with the aim of suiting every wheel. The E-clutch are mounted twist-proof on the axle of the rear wheel by the patented polygon fastening system.

The coupling versions E, EL and ES connect the way they are mounted on the rear axle of the bicycle.

The E-coupling is the most universal of the three couplings and the most frequently used of the three E-variants. Subdued with inner rubber buffer, it is suitable for transporting cargo and children.

Our clutches are only for bicycles and pedelecs (max. 25km/h) allowed, not for S-Pedelecs or e-bikes from 25km/h! An e-clutch cannot be mounted for rear-wheel engines!
For safety reasons, we advise you to have the clutches on the bike mounted by your specialist dealer.

We would like to point out to all dealers and end consumers that you are responsible for the overall system of bicycle trailer and its correct function in the interests of product liability!

Due to the various forms of bicycle failing and gear versions, our couplings do not generally fit all bicycles. Commonly thicker special polygons are needed for quick-release axles, special polygons for hub switching or the replacement plug axle X12.

Features E-EL-ES – Coupling

Mounting on the bike

The E-couplings are fixed to the left, rear failure with the quick clamp, the screw axis or with the Weber replacement thrule. A polygon insert that interferes with the failing of the frame ensures the coupling against twisting and is used to adjust the angle of the clutch.

Installation problems exist at:

• Rohloff gear hubs with full axis. Here, the Weber ER coupling is recommended, provided that a movable Rohloff failing is available.
• Bicycles with short, vertical droppings
• Tricycles or. Special bicycles please contact the respective manufacturers, for example. HP Velotechnik; Rabbi Special Wheels; Arved Klütz etc.
• not usable when dropouts opened horizontally to the rear (e.g. almost all Gazelle models)
• not usable for wheels made of carbon or with carbon dropouts and carbon rear.
