BUZZ RACK BuzzRacer 4 bike wheel support rack no. BRP334

RRP: 317.50
Code: BRP334

A great all-rounder, the Racer offers fantastic value for money and the built quality is among the best we have found. This rack is also easy-to-use; loading your bikes is simple and it tilts to allow access to your tailgate.

A great all-rounder, the Racer offers great value for money and the built quality is among the best we have found. This rack is also easy-to-use; loading your bikes is simple and it tilts to allow access to your tailgate.

Assembly: Even though it is not assembled the Racer 4 is very easy to put together: assemble the wheel support frame to the base using the supplied screws, assemble the light support with 2 more screws, install the license plate, slide in the plastic wheel supports, fit the rack to the tow ball with no tools needed and you are ready to go.

Fitting to the car: When you first place it on the tow ball it supports itself - you can let go of it and it won't fall to the ground. You'll then take the weight again, spin the tightening wheel until it's tight, and lock it. BUZZ RACK's carriers comply with the very exacting standard XPR-18-904-4 and therefore include an anti-sway tensioner; this has an integrated handle and 2 or 3 turns are usually sufficient.

Lighting system: The BuzzRacer comes with a 7 pin lighting system, adapters are available if you have a 13 pin socket - see below.

Tilting: Tilting is easy, and is very well balanced even with a full load. The Racer 4 sits quite high on the tow ball, and the tilt function is optimised to prevent the lights from hitting the road surface, while still using the weight of the bikes to help bring the bike platform back to the level again in a controlled way. It will tilt far enough to open the tailgate on normal hatchbacks, estates, saloons and SUVs. Feedback suggest this rack tilts far enough to open the tailgate on an S-Max and similar cars, this would depend on the position of your tow ball. You can check how far this rack tilts in the diagram in the 'technical information' tab. This geometry doesn't allow for vertical tailgates to be opened - the only tow bar carriers we know about that are suitable for these vehicles, e.g. VW Transporter T5 and T6, and MPVs such as the Vauxhall Zafira and Ford Galaxy, are the Atera STRADA DL3 (maximum 4 bikes) and the Atera Genio Pro (maximum 3 bikes).

Carrying bikes

  • The long rubber-padded wheel straps hold tyres up to 3.25 wide; pull on them to tighten, and use the quick release to loosen
  • A strap extension kit (available separately) adds 10cm to the length of the original wheel straps
  • The frame holders are suitable for carbon frames, the rubber bike frame pads and high resistance straps hold any type of tube firmly but gently.
  • Includes a built in cable lock to secure your bikes to lock your bikes to the rack.
  • The wheel holders will accommodate small childrens bikes to full size bikes with wheelbases up to 119cm. You can reverse the wheel supports for the really small bikes.
  • The carrier folds flat for easier storage.
  • It's the right shape for storing in the boot when not in use.
  • All parts are replaceable if e.g. someone forgets that a tow bar carrier is fitted and reverses into a wall - which happens!
  • Dimensions (width x depth x height): 88 x 94 x 73 cm (measured from the centre of the tow ball mount to the outside edge of the number plate holder).
  • Weight: 18kg.
  • This rack is supplied with UK standard 3 function lights and a 7 pin plug; electrical adapters are available for those with 13 pin systems - see below.
  • The build quality - tube bending, welding, rust proofing, painting, component quality, is exemplary. All tools you might need are provided.

Exchange scheme: Tow bar carriers are part of our 90 day exchange scheme - click on the link below for details - so you can order without financial risk. All current tow bar carriers from all the brands we stock are available for exchange, even if they are no longer part of our standard stock range.

BUZZ RACK is manufactured by King Rack of Taiwan, a specialist bike sector engineering company since 1996. Their factory is state of the art, with much of their production being tube bending, specialist welding and finishing for well known brands.

Deciding which bike carriers to buy is not always easy, especially as you may not have had experience of using bike carriers before. We hope that our buying guides provide useful guidance about which bike carrier 'strategy' will be most appropriate for your circumstances, as well as highlighting the best features of particular models. We also have troubleshooting FAQs - for example, some customers struggle at first to fit four bikes onto a tow ball carrier, and wonder whether a different carrier would allow the bikes to be spaced wider apart. (It won't, but we have some good tips which make bike fitting much easier.)

Our bike carriers Exchange Scheme covers roof mounting and tow ball mounting bike carriers only. Rear door mounting / strap on carriers are not included, and nor are roof bars. It allows you to exchange within 90 days of invoice date. Most exchanges are for roof mounting upgrades, or are tow ball carriers with very basic tilting systems being exchanged for easy to use sliding / tilting carriers.

These are the rules of the bike carriers Exchange Scheme:

  • You are allowed one exchange only.
  • The original equipment must be in "as new" condition, subject only to fair wear and tear.
  • The replacement items must be different models from the originals.
  • The replacement items must not be part of a package deal or be from our Bargains section.
  • Roof bars are never part of the Exchange Scheme.

This is how the exchange scheme works:

  • We charge in full for the replacement items, including the appropriate carriage charge and a charge for any packaging needed for the return of the originals.
  • We pay the return carriage costs.
  • When the originals arrive back here we refund you for their invoice value but you won't get back more than the invoice value of the replacements. In other words, if the replacements are cheaper than the originals we won't be giving you "extra cash back".

Please note that we can only collect exchange scheme items from mainland UK.

Delivery charges and arrangements:

We charge a contribution towards delivery costs, depending on what you order, where you live, and how quickly you want the goods.

These are our standard charges; there are usually surcharges for all offshore destinations and some remote postcodes - for details please see our delivery information page.

Delivery FAQs

When will my order arrive?
There are no deliveries on Saturdays, Sundays or Bank Holidays, except for postable items where Royal Mail has a Saturday delivery. Express Delivery orders placed on a Friday (before 1pm) should be delivered on the Monday or Tuesday, Express Delivery orders placed on a Saturday or Sunday should be delivered on the Tuesday or Wednesday. The arrangements for Very Heavy Items are different and are shown above.

What about Next Working Day delivery?
Most Express delivery orders will arrive on the next working day, if the order is placed before the cut-off time (see above). Some will arrive on the second working day if there has been a "split-delivery". So-called split deliveries happen when the couriers do not have enough trailer space for everything that should be moved around the UK, so they will load what they can and leave the rest for the next trailer.

Is my delivery day guaranteed?
No retailer or courier company can ever "guarantee" a Next Working Day delivery. As well as split deliveries, all courier companies occasionally have the same transport problems as can happen to everyone else, including snow blocked roads, closed roads, traffic jams, mechanical breakdown, an inability to find the delivery address, or to gain access to it if, for example, it's in a block of flats. We work with some of the best couriers in the business, and overall they provide an outstanding service.

Do I need to be at home?
We are very flexible with our deliveries and will aim to deliver to an address which suits you this does not need to be your home address. Goods can usually be left without signature - we prefer this with roof boxes. There's a "Special Delivery Instructions" box in the checkout area where we'll ask you to choose a typical instruction and then amend it to suit your particular requirements.

We take the following cards, and also PayPal. Please note that the entry on your card statement will be from "The Roof Box Company".

Bike carriers with 7 pin plugs

Wheel support bike carriers which are supplied with 7 pin plugs usually only include rear lights, brake lights and indicator lights, which is why they are often called 3 function lights.

Unusually, Thule bike carriers with 7 pin plugs also include a fog light; this works when plugged into 7 pin electrics, but it does not work when plugged into 13 pin electrics via an adapter.

Bike carriers with 13 pin plugs

Bike carriers which are supplied with 13 pin plugs include a fog light and reversing light, as well as rear lights, brake lights and indicator lights which is why they are often called 5 function lights.

If these are plugged into 13 pin electrics then all 5 functions will work.

If they are plugged into 7 pin electrics via an adapter then the fog light should work, but the reversing light on the bike carrier will not work.

Please note

These notes assume that your tow bar electrics have been wired correctly!

Tow bar wiring in the digital age is much more complicated than it used to be when everything was analogue. Our experience is that if you are having lighting problems, e.g. a fog light does not work in 7 pin tow bar electrics, the problem is much more likely to be caused by the wiring, not by a dud bulb in the bike carrier.
