Many of our customers at Megatyre Towbars, North Shore, Auckland, fit towbars just for their bike racks; often they specify a towbar without the electrical wiring as they say they have no intention of ever towing anything. In most cases, there is no problem installing electrical wiring at a later date.
All bike racks fit both 1 7/8ths and 50 mm size towballs with the exception of South African bike racks which almost never fit on the New Zealand style towbar.
On some Four Wheel Drive vehicles, the spare tyre is on the back door and extends over the towball. In these cases, either a towbar extension (for bike racks only) or a special bike rack with a curved shaft will be required. Some motorists even fit Motorbike racks to their towbars; customers often specify extra strengthening on our custom made towbars for uses like this.
