Hub system and vehicle

A hub system includes a hub shaft; a driving member and a hub shell mounted with respect to the hub shaft. A brake shoe is arranged for engaging the hub shell to temporarily be coupled with said hub shell and a brake anchor is arranged to be attached to a frame and a coupling element is arranged for enabling coupling between the driving member and the hub shell in a first position, and for enabling coupling between the brake anchor and the hub shell in a second position. The hub shaft is rotationally coupled to the brake shoe in one rotational direction at a first location located at a first lateral side of the driving member, and to the brake anchor in one rotational direction at a second location located at a second lateral side of the driving member and opposite of the first lateral side of said driving member.
