Allen MT1-B ultra-compact folding boot rack vs CAM Biker roof carrier, 1 bike

For one bike: boot or roof?

Both carry a single bike and both cost about the same. One needs nothing on the car and folds into a bag; the other needs crossbars you may not own and leaves the boot free.

A tick marks the better answer on that line only. Counting ticks does not decide the page — the two verdicts below do, because these products answer different questions.

Which of the two, for which rider

Buy the MT1-B ultra-compact folding boot rack

The answer for a flat with no storage. It folds into a supplied bag small enough for a rucksack, which is the entire product — a rack that occupies a garage corner for eleven months is a rack that costs you space all year. The boot is inaccessible while loaded, and the plate and lights are obscured.

Buy the Biker roof carrier, 1 bike

The answer if you already have crossbars. The boot stays usable, there is no rear overhang, and fitting is two hand knobs. It adds roughly 130 cm (51.2 in) of vehicle height, which is what car parks and height barriers punish.

The questions riders ask

Do I need to buy crossbars?

For the CAM, yes, unless the car already has them — and they frequently cost more than the carrier itself. Many cars have roof rails; the bars that span them are a separate purchase. Price them first.

Will a boot rack fit my car?

Fitment is vehicle-specific and a spoiler or a rear wiper changes the answer. Allen explicitly directs buyers to check vehicle-specific data rather than claiming universal fit, which is the right instinct.

Do I need a lighting board?

Once bikes obscure the plate and lights, most European countries require a repeated plate and a board. The rules are national and they change — read them for every country on your route.
