Flying isn’t the only time your bike box travels. Whether it’s the drive to the start of a training camp, a race weekend, or simply the airport car park, most Buxumboxes will spend some time in the back of a car as well as in the baggage hold of an Airbus or a Boeing.
So how easy is it to get one in? We tested three typical vehicles - a Volkswagen Golf Mk 8 hatchback, a Škoda Octavia Mk 4 Estate, and a Volkswagen Transporter T6 (LWB) - against the full Buxumbox range: Tourmalet, Ventoux, Aubisque, and Stelvio. Here’s what we found.
Dimensions of our boxes
Before diving in, it’s worth recapping on the external dimensions of our boxes that we’ll be talking about:
Ventoux:
- W1 (Standard): 1,340 × 870 × 360 mm (52.8 × 34.3 × 14.2″)
- W2 (Wide): 1,340 × 870 × 410 mm (52.8 × 34.3 × 16.1″)
Tourmalet:
- H1 (Low): 1,180 × 800 × 310 mm (46.5 × 31.5 × 12.2″)
- H2 (Mid): 1,180 × 840 × 310 mm (46.5 × 33.1 × 12.2″)
- H3 (High): 1,180 × 880 × 310 mm (46.5 × 34.6 × 12.2″)
Aubisque Standard:
- H0 (Low): 1,340 × 750 × 490 mm (52.8 × 29.5 × 19.3″)
- H1 (Mid): 1,340 × 790 × 490 mm (52.8 × 31.1 × 19.3″)
- H2 (High): 1,340 × 830 × 490 mm (52.8 × 32.7 × 19.3″)
- H3 (Max): 1,340 × 870 × 490 mm (52.8 × 34.3 × 19.3″)
Aubisque Wide:
- H0 (Low): 1,340 × 750 × 550 mm (52.8 × 29.5 × 21.7″)
- H1 (Mid): 1,340 × 790 × 550 mm (52.8 × 31.1 × 21.7″)
- H2 (High): 1,340 × 830 × 550 mm (52.8 × 32.7 × 21.7″)
- H3 (Max): 1,340 × 870 × 550 mm (52.8 × 34.3 × 21.7″)
Stelvio:
- L1 (Standard): 1,340 × 870 × 360 mm (52.8 × 34.3 × 14.2″)
- L2 (Long Wheelbase): 1,520 × 870 × 360 mm (59.8 × 34.3 × 14.2″)
When loaded flat into a car boot, the depth dimension is what determines vertical clearance - so think of that as the "height" when the box is on its side. The deepest box in the range is the Aubisque Wide at 550 mm.
Hatchback: Volkswagen Golf
The Golf is the yardstick for a typical hatchback, and it handled more than you’d think.
- Boot length (seats up): ~800 mm
- Boot length (seats down): ~1,493 mm
- Aperture width: ~1,020 mm
- Aperture height: ~750 mm
With the rear seats folded:
- Tourmalet (1,180 mm long) fits comfortably with around 313 mm to spare.
- Ventoux and Aubisque (both 1,340 mm long) fit with around 153 mm spare - tight but workable, loaded straight in.
- Stelvio Long Wheelbase (1,520 mm long) exceeds the folded load length by around 27 mm, so it'll need an angled load and possibly a small front-seat adjustment to slide right in. The shorter Stelvio Standard (1,340 mm) fits like a Ventoux.
Even the deepest box (Aubisque Wide at 550 mm) clears the ~750 mm tailgate aperture comfortably, and at 870 mm wide every box fits well within the 1,020 mm aperture.
On-the-road tip: fold the seats, roll the box in wheels-first, and angle it slightly towards the off-side rear corner if you're loading a Stelvio Long Wheelbase.
Estate: Škoda Octavia Estate
If the Golf was a close call on our longest box, the Octavia Estate is the easy win. Estates remain the sweet spot for travelling riders - low sill, long load floor, acres of usable width. Plus, estates are just great in general, right? With the seats folded, every Buxumbox fits comfortably.
- Boot length (seats up): ~1,090 mm
- Boot length (seats down): ~1,860 mm
- Aperture width: ~1,000 mm
- Aperture height: ~852 mm
Even the longest box, the Stelvio Long Wheelbase at 1,520 mm, fits with around 340 mm of length to spare. The 852 mm aperture height clears any box's depth dimension (max 550 mm) easily, leaving plenty of room to lift and load. You can stow a kit duffel and extras alongside without any drama.
On-the-road tip: Keep the box flat against the boot floor and place lighter accessories (helmet bag, shoe bag) on top. The anti-crush bar will protect your bike from compression in the box. The estate layout makes for ideal road-trip or ferry-crossing setups.
Van: Volkswagen Transporter (LWB)
No surprises here. If the estate handles the lot, the Transporter swallows everything with room to spare. It's the benchmark for teams and riders who travel heavy.
- Load length: ~2,975 mm
- Load width: ~1,700 mm
- Rear-door aperture: 1,473 (W) × 1,305 mm (H)
- Side-door aperture: 1,030 (W) × 1,301 mm (H)
A single box has masses of room behind it:
- Tourmalet (1,180 mm) leaves around 1,795 mm of spare length
- Ventoux, Aubisque and Stelvio Standard (1,340 mm) leave around 1,635 mm
- Stelvio Long Wheelbase (1,520 mm) leaves around 1,455 mm
That makes the Transporter ideal for stacking multiple boxes end-to-end. Two Tourmalets fit easily (2,360 mm total - around 615 mm spare), and two of any 1,340 mm box (Ventoux, Aubisque or Stelvio L1) also pair end-to-end with around 295 mm spare. Two Stelvio L2s are the only combination that won't sit straight end-to-end (3,040 mm vs 2,975 mm of load length), so for a paired Stelvio L2 setup you'll either stagger them slightly or use the side door to load.
Side-by-side, most pairings work. Two Tourmalets (310 mm deep each) fit with metres of room. A Tourmalet alongside a Ventoux or Aubisque is no problem either. The exception is pairing two of the widest boxes flat - e.g. two Aubisque W2s lying flat take up 1,740 mm of width (just over the 1,700 mm load width), so you'd stagger them lengthways or stand one on its edge.
The 1,305 mm rear aperture height clears any box's depth dimension (max 550 mm) several times over.
On-the-road tip: secure boxes with soft straps or chocks to prevent rolling. The Transporter's side door makes it practical to load one box through the side and another through the rear if you're maximising space.

| Octavia Estate | 1,090 / 1,860 (folded) | 1,000 × 852 | All models | Seats folded required — flat, easy load with room to spare |
| VW Transporter LWB | 2,975 | 1,473 × 1,305 | All models, plus most pairings | Masses of space; two Stelvio Long Wheelbases won't sit straight end-to-end |
Every Buxumbox will fit in an average estate car, and most will fit in a hatchback with the seats down. Only the Stelvio L2, designed for the longest mountain bikes, pushes the limits in smaller cars.
If you're planning to drive to an event, fold the seats, clear the boot floor, and measure your load space from tailgate latch to seatback - anything over about 1,350 mm covers most boxes, and 1,520 mm clears the Stelvio Long Wheelbase. If loading inside isn't an option and you'd rather not drop the rear seats, we can produce custom mounting brackets for roof racks - use our chat functionality in the bottom right of your screen to discuss this.
For teams or group travel, a medium-size van like a Transporter is ideal but not essential. The point is simple: you don't need specialist transport. A standard car does the job.
