Before you fit our adapter, you must determine whether your bike is approved for trailer use. Check the operating instructions for your bike, ask the manufacturer or ask a bike dealer.

The towing bike must be approved for trailer operation. Riding the trailer with a towing bike that has not been approved by the manufacturer can lead to frame breakage or other material problems. This can result in accidents with life-threatening injuries.

If you are not sure how to install our adapter correctly, please contact a specialist workshop.

Our adapter must be fitted correctly. An incorrectly fitted adapter can come loose while riding and lead to accidents with life-threatening injuries.

You should definitely bear this in mind: 

• Our adapters are only approved for bicycles and pedelecs (max. 25 km/h), not for S-pedelecs or e-bikes from 25 km/h!

• We would like to point out to all dealers and end users that they themselves are responsible for the entire bicycle trailer system and its correct functioning in terms of product liability!

• It is your responsibility to determine the correct thread size of your rear hub on your bike. Do not attempt to fit our adapter with a different thread size to your rear hub. An incorrect thread size can damage your bike. If you are unsure of the correct thread size, please contact us by email or phone and we will be happy to help you. 

• cannot be used with bikes made of carbon or with carbon dropouts and carbon rear triangle!

• Regularly check the correct torque setting and that all components are free of play before using your bike in trailer mode!

• If you do not have a calibrated torque wrench for fitting our adapter, contact a specialist workshop.

FOR ASSEMBLY

After you have removed your current two M8 x 40mm cylinder screws from your rear triangle (frame), you can now screw our M8 x 40 threaded bolts into your Enviolo gear hub on the left and right.

To tighten our M8 x 40mm threaded bolts, you will need a 15mm open-end wrench.

Please refer to the operating instructions for your bike for the tightening torque; we recommend a maximum of 16 Nm.
