It is possible to add cycles to your vehicle, as long as they are attached to the car and not on a separate trailer. The only thing that you need to check is that adding them does not take the height of your vehicle over 6ft/1.85metres. The same height restrictions apply to vehicles carrying roof racks or roof boxes. If they do make your vehicle over the 6ft/1.85m limit and you have a low space booking, you need to amend the booking to high space. There are far fewer of those and you could have a long wait if you are booked incorrectly. If you would like assistance please call our Contact Centre.
