Compatibility, Size and Fit
The ZX204 is made for a 50 mm towball and uses a supplied lightboard with a 13-pin plug. The stated bike fit limits are important: max tyre width 8 cm, max distance between bike wheels 120 cm, and distance between rails 17 cm.
The rack is described as suitable for children’s bikes, and the adjustable wheel holders are part of that setup. Buyers should still check the bike dimensions and weight against the stated limits before choosing an offer.
