Got a car without a towball but want to carry your bicycle around with you? Yes it can be done, albeit with a few compromises.
Pros:
* save on the cost of a towball. Getting a towball fitted starts at around $300 for simple vehicles
* cheap - this product is just $99 and away you go... sort of (see number plate issue in the Cons section)
* this product is quite light and foldable so can easily live in the boot of the car for whenever you may need it
