The Best BMW Z4 Bike Rack

By on 18 May 2021 / Leave a comment Updated on: 18th May 2021

A 2-seater convertible may not be the last word in practical, load lugging transport. That doesn’t mean however, that owners don’t want to get out and explore the world both on 4-wheels and 2. While the boot space of a Z4 is clearly not designed for those with a passion for cycling, externally mounted bike racks can provide the ability to take one or two bikes to wherever in the country you need, without compromising internal space.

External bike racks come in many forms, from roof mounted bars and boxes to those mounted aft, attached via a tow bar or multitude of straps. They will generally carry anywhere from 1 to 4 bikes and save on internal space to carry all your extras, whether that be camping equipment for a weekend adventure or just your helmet and water bottles.

BMW Z4’s come in both convertible and coupe forms. The latter offers extra internal boot capacity and as such, it is recommended not to mount bikes externally on these models. Not only can bikes fit inside the vehicle, but the extended rear glass could be damaged by fitment of a rear-mounted bicycle rack.

Types of Bike Rack

Essentially bike racks can be split into three types; roof mounted, rear mounted and tow bar mounted.

Being a convertible (soft roof) and lacking a tow bar, the BMW Z4 will really only work with a rear mounted option. These come in a variety of shapes but the three we’ve highlighted below will be ideal for use on a BMW Z4, coming recommended by many current and past owners.

Rear mounted units sit against the boot lid, securing the bikes via straps or tie downs and then securing the bike rack to the vehicle with a multitude of adjustable straps. These are highly engineered and reliable units, preventing the chances of your 2-wheeled pride and joy cartwheeling down the outside lane of the motorway.

Things to Consider Before Purchasing

Are They Vehicle Specific?

While some bicycle racks can be specific to an individual vehicle, most have large levels of adjustment to allow them to suit a multitude of different shapes and sizes of car. This not only allows for manufacturers to focus on just a handful of products but, also makes it much easier to pick the right product to fit any car.

As mentioned, these bike racks are adjustable and should suit any Z4 convertible, coupes are not suitable for rear-mounted bike racks due to the large glass rear screen. Owners are advised to instead place their bicycle inside the larger boot space of the coupe to negate any risk of damage or non-fitment due to the cars unique shape.

Fitment with a Spoiler

Many owners choose to adorn their BMW Z4 with large spoilers for extra style and performance. While owners with small lip spoilers will likely get away with strapping a bicycle rack over the top, those with large spoilers may need to remove them in the case of using a bike rack.

Thankfully, bike racks are quick and easy to remove and install, allowing owners to replace the spoiler and only remove in instances where the bike rack is being used.
