The article is basically well-made and functional well usable. It is possible to charge bicycles alone. Other bicycle racks from Thule require the dismantling of the front wheel. This is on one hand a disadvantage, but can also be an advantage because the bike is fixed directly while charging with a fork in a holder. In the present system one must instead lean "means support" on the bike. This can be quite shaky and requires some strength and skill, on the one hand to balance the bike and on the other hand, tighten the central arm. Conversely, you do not have to make the effort here, dismount the front wheel, which can be an advantage. A carrier (I have three) is to me a wheel holder (a movable plastic part, the front and back to see the product picture) broken, so a point deduction.
