Mercedes-Benz recommends removing all
de tach able parts from bicycles (e.g. bask ets,

Alw ays secure the bicycles topreve ntthem from
moving around and check them at regular inter‐

Do not use tarp aulins or other co vers. The driv‐
ing characteristics and rear view may be
impaired. In addition, aerodynamic resis tance
