The Buzz Rack Beetle is a classic among strap racks. It is designed to fit most cars. It also has the huge advantage of not taking up space in your car trunk. Quite small and light for a product that can carry up to 3 bikes.

The carrier attaches to your vehicle using 6 straps, each with a rubber coated hook. They hook onto the top, sides and bottom of the trunk or rear door. It will almost certainly require lighting and a license plate in most cases.

Carries up to 3 bikes (Max 3 x 15kg = 45kg)
