BUZZRACER series offer convenient mounting, user-friendly functions and compact storage. The ratchet cradle is the perfect solution to attach the bike frame. It is also a great solution for carbon frames as it does not apply pressure to the carbon tubes. This would be the most economical solution to carry 4 regular bikes (no ebikes) with a tilting function that gives access to the trunk.
 
Assembly: Even though it is not assembled, BUZZRACER 4 is very easy to put together: assemble the wheel support frame to the base using 8 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 the BUZZRACER 4 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 knob until it’s tight, and lock it. BUZZRACK‘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. The video below shows the fitting to the car and the installation of bikes.
Tilting: Tilting is easy, and is very well balanced even with a full load. The BUZZRACER 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. But this geometry doesn’t allow for tall vertical tailgates to be opened – e.g. VW Transporter T5 and T6.
Other features and specifications:
Carrying bikes
The wheel holders will accommodate most wheelbases, even small children’s bikes. You can reverse the wheel supports for the really small bikes.
The long wheel rubber-padded wheel straps hold tyres up to 3.25” wide; pull on them to tighten, and use the quick release to loosen
The BUZZRACER 4 is entirely suitable for carbon frame bikes; the rubber-padded bike frame cradles rotate 360 degrees and, again using rubber-padded straps, they hold any type of tube firmly but gently.
The maximum permitted load is 60kg, with no bike weighing more than 20kg
The down tube size is limited to 75mm diameter (3″); whatever bikes you have, always load the heaviest bikes nearest to the car
There is a built in locking cable to secure your bikes; as usual with cable locks, it’s a deterrent only.
Other features and basic specifications
Dimensions: 88cm wide x 94cm deep (measured from the centre of the tow ball to the outside edge of the number plate holder).
The build quality – tube bending, welding, rust proofing, painting, component quality, is exemplary. The whole carrier looks and feels like the class act it is. All tools you might need are provided.
The maximum permitted load you can carry is also determined by the tow bar nose weight; you will need to check you don’t exceed this before using any tow ball mounted bike carrier.
Requires 65mm clearance from center of tow ball to rear of vehicle.
Not suitable for trailers, campers, or RVs
