For my money, I think this is the best option for a bike rack, subject to the presence of a towbar. It is difficult to add something, because it is exactly the same as it is in the photo / video: in fact, these are two crossed sticks that are securely fixed on the towbar without the help of additional devices. The hanging strap serves exclusively for additional fixation of the front wheel (for example). Removed with the push of a button. Bliss.
