Rear bike rack
I don't understand if the rear bike rack can be mounted on my car
To check the possibility of fitting one of our rear bike racks, you need to check its
search engine compatibility on the home page
I checked the compatibility with my car but it doesn't indicate any compatible products
All the cars listed in our search engine have been personally checked by
part of our technicians. If a car is not compatible it may be due to the presence of parts
plastics or sheaths in the tailgate that do not allow it to be anchored. In this case you should opt for a
roof or towbar bike rack.
We invite you not to use the product even in the event of a negative outcome, as in the event of damage our
company cannot respond in any way.
Which year should I enter when searching for rear bike rack compatibility?
It is necessary to check the year in which your car was first registered (this information is
available in the vehicle registration document). Once the year has been checked, the list showing the
several years you will have to refer to the band that includes the year of your car (e.g. if your car was
registered in 2014 and the years from 2012 to 2015 are listed in succession within the search
2015 will have to refer to this)
The compatibility search does not indicate the year in which my car was registered
When the list of different years appears, you will have to refer to the range of years in which yours is
included (e.g. if your car was registered in 2014 and the search lists
from 2012 to 2015 will have to refer to that range of years).
I got the following message: “Use the light and license plate repeater bar (to be purchased as an optional extra)” is this really a necessary option?
Yes we confirm that it is necessary to use a bar that repeats the lights and the license plate, when you will mount the
rear bike rack on your car, in fact, once the bikes are also fixed, the lights will be covered and not
will be clearly visible to those who follow it. In this case it could be punishable by the police
of the order and on the part, in the event of an accident, it could have insurance problems, therefore the
we invite you, if it is specified in the compatibility search you carried out, to
purchase our optional which you can also find in our online shop.

I searched for compatibility of rear bike racks and the following statement came up: “Use the light and license plate repeater bar (to be purchased as an optional extra)”. Is an electrical connection required?
The light and license plate repeater bar requires an electrical connection, you can go to your
trusted auto electrician and ask that the appropriate plug be applied to your car. The type of plug
used on this type of optional is “7 poles”, in case it already has a different plug or
If the auto electrician provides you with a different plug, you will simply need to purchase a special adapter available in
any car accessories store. The optional can also be purchased in our online shop.
Is it necessary to use the red and white striped sign for protruding loads?
Since the bike rack, loaded with bikes, is an actual protruding load, we recommend using the provided sign
by law. As per the instructions, once the bikes are loaded, you should also pay attention that
license plate and lights are clearly visible, otherwise you could be subject to fines by the police
as well as risking possible insurance problems in the event of an accident.
If I use a rear bike rack can I open the tailgate?
Once the bike rack has been mounted, especially if you have already loaded the bikes, we do not recommend opening the
tailgate as the car's hinges are not designed to support such weights when opening.
Even when the bike rack is unloaded, we still ask you to pay particular attention during loading.
opening as the upper temples and upper fastening hooks could push on the bodywork
and cause damage.
Can I use a rear bike rack if my car has an automatic tailgate?
Cero can use the rear bike rack but must be careful not to open it, even
unintentionally, the car tailgate once the bike rack is mounted.
Can I use the rear window wiper once the bike rack is mounted?
No, it is not possible to use the rear window wiper and we recommend deactivating any functions that
allow the automatic switching on of the same when reversing.
My car is not yet tested, what do I do?
If during the search the following message appeared: “We are sorry but your car model is not yet available”
has been viewed by our technicians and we are unable to provide you with any information" we confirm that

updated regularly, I just ask you to try to look on our site regularly.
