recommends removing all
de tach able parts from bicycles (e.g. bask ets,
ch ild seats, rech arge able bat teries) before load‐
ing them onto the bicycle rack . This will impr ove

va ls to ensure that they are secure.
Do not use tarp aulins or other co vers. The driv‐
ing characteristics and rear view may be
