Assembly of auxiliary wheels
1.
Preparation of place and tools
Make sure you have enough space to handle the bike and all the necessary tools. You will need a size 15 open-end wrench or the multi-wrench that we packed with your bike.
2.
Replacement of covers
Remove the plastic caps on the wheel axles from the bicycle.
3.
Enabling matrices
Loosen the outer nuts on both sides counterclockwise. Under these large mothers you will find another (smaller! - do not remove these). They hold the wheel against movement so that your bike does not go out of tune.
4.
Embedding
Put the silver washers that came in your bag with the auxiliary wheels on these smaller nuts and put the arms of the auxiliary wheels on top of them.
5.
Tightening the auxiliary wheels
Return the nuts to the axle and tighten the auxiliary wheels clockwise.
6.
Check
Put the plastic end caps back on the bike and check that the wheel can turn freely and that the brakes are working properly. You shouldn't get the bike out of tune thanks to the locknuts. If you've accidentally loosened them or the rear wheel has moved, check your brake manual.
