Morning Dashen
Personal choice , vehicle specific and/or application requirements...
So if you have a bakkie/trailer there are a few options on which a bike can be loaded onto...towbar specific carriers - hanging/ride-on type...I prefer ride-on type - bike is fixed onto a carrier.... or the type you "strap" to your vehicle (normally used on hatchbacks).
And last but not least ... how big is your wallet ...
I have a thule since 2006, holdfast since 2020 ... no issues on either thusfar ... so a few brands you can have a look at Buzzrack,Thule or Holdfast.I am sure there are more threads on this topic...
