Quick Summary
A clamp on towbar mounted bike rack for carrying two bikes with easy loading, tilt access and a supplied rear light board.
What This Product Is Used For
The Witter ZX302 is a clamp on towbar mounted bike rack designed for transporting up to two compatible bikes on the rear of a car. Compared with a roof mounted bike carrier, this towbar mounted design keeps bikes lower, making loading and unloading easier. It is used for family cycling trips, holidays, weekend rides and transporting adult or children’s bikes where towbar mounting is preferred. Users choose it over simpler racks because it includes a lockable clamp down lever, adjustable wheel holders, two individual support arms, tilt access and a supplied rear light board with 13 pin plug.
Who This Product Is Best Suited To
This bike rack is best suited to users who want a practical rear mounted carrier for two bikes and prefer not to lift bikes onto the roof. It suits drivers with a compatible 50mm towball who want quick fitting, stable bike separation and easier access to the boot. It is also useful for families because the adjustable wheel holders can mount children’s bikes as well as many common adult bike types.

Real World Performance and Day to Day Use
In day to day use, the Witter ZX302 is designed to make two bike transport more manageable. The clamp on towbar mounting system uses a lockable clamp down lever, helping users fit and remove the rack quickly when needed.
The low platform is useful because bikes do not need to be lifted high, while the two individual support arms help keep bikes separated and reduce contact between cycles. Adjustable wheel holders allow most common bike types to be transported, including children’s bikes, provided the size and weight limits are suitable. The rack can also tilt when loaded, allowing more convenient access to the boot.
Choose this if you want a two bike towbar carrier with easy loading, boot access and a supplied light board.
Skip this if you need to carry bikes over 17 kg each, use a van vehicle or do not have a compatible 50mm towball.
Why We Like This Product
The YPC Team likes this because it gives cyclists a practical way to carry two bikes without the strain of roof loading. It helps avoid the common mistake of choosing a rack without checking individual bike weight limits, and it reduces the regret of buying a carrier that blocks boot access during trips.

Tips for Getting the Best Performance
Check your towball is 50mm before buying. Confirm each bike weighs no more than 17 kg and that the total load does not exceed 34 kg. Use the adjustable wheel holders to secure each bike properly before travel. Check the maximum tyre width of 8 cm and maximum wheel distance of 120 cm against your bikes. Use a 7 pin adaptor if your vehicle does not have a 13 pin socket. Do not use this rack on van vehicles because the supplied information states it is not applicable for them.
