ExtraWheel

Do it carefully for the first time – The next time you attach the trailer it will take you less than five seconds.

- Remove the quick release from the bicycle
- Mount the Extrawheel quick release
 

- Choose the correct size of Extrawheel nuts
- Take the nuts off the bicycle
- Screw in the Extrawheel nuts with a 15mm box wrench
 

- Find a place for Extrawheel nuts M5
- Screw the nuts in
 

Mount the wheel in the trailer

Use the enclosed wrench to check if the screws are tight

Check the widening of arms; it must be possible to put the fork on the bicycle quick release or nuts like a spring by spreading its arms by 3 cm (the height of Extrawheel nuts), not more or less

Unless it fits, loosen the screws, adjust the arms and tighten.

It is convenient to place the fork against some flat surface.
 

Hang the fork on the trailer.

Clean the fork bearings and ball-shaped joints, lubricate and protect them against impact.

Protect bicycle joints with protective caps whenever the trailer is not attached.

Protect the trailer joints whenever you store or attach the trailer with the fork on.

Do not exceed the speed of 40 km/h while riding downhill
Do not tow the trailer in high wind.
If hit by a car, the Extrawheel trailer will detach itself from the bicycle.
It may also detach if:
- you ride at an acute angle onto an obstruction, such as a kerb,
- you fail to lean the bicycle to the inside while backing up with sharp joint bending
