The Bikeinside inside bike carrier is in principle suitable for station wagons. It must merely be ensured that the bikes fit upright with extended front wheels in your station wagon. An assembbly in driving direction and possibly against driving direction is possible.
Try if your bike fits upright (remove front wheel, eventually saddle and travel down your suspension fork and remove rear wheel when needed) in your car. If this is possible you can use the Bikeinside bike rack for the interior of your station wagon.
Unfortunately we can not make a general statement for station wagons, as to the combination of bicycle parts such as mounting handlebars, fenders, racks, etc. and the vehicle are too individual.
