The Bikeinside inside bike carrier is in principle suitable for pickup trucks. It must merely be ensured that the bikes fit upright with extended front wheels in your pickup truck. 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 pickup truck.
Unfortunately we can not make a general statement for pickup trucks, as to the combination of bicycle parts such as mounting handlebars, fenders, racks, etc. and the vehicle are too individual.
Please also look at our customer photos with many examples.
