Fast, Simple Packing

Ten minutes from stand to travel-ready and back again when you get there. Less stres, less admin, more riding.

The Stelvio. Maximum capacity for your big mountain rig.

The Stelvio is built for the bikes that don’t fit anywhere else, making it the only dedicated long-wheelbase MTB bike box on the market, with two size options covering wheelbases from 1025 mm to 1410 mm. If your XC, enduro, downhill, or trail rig has always been a tight squeeze in other boxes, the Stelvio gives it room to breathe while keeping it safe in transit.

  • Ten-minute packing: Get your bike ready for travel in record time.

  • Minimal disassembly: Simply remove the wheels, handlebars, and seatpost—dropper posts can often stay in on smaller frames.

  • Tailored protection: Secure the frame using twin anti-crush bars with three adjustable mounting positions.

  • Streamlined design: Forget the foam, straps, and guesswork of traditional bike bags.

  • High security: Four-to-six latches and a central TSA-compliant lock keep your gear safe during transit.

  • Clean access: The lid opens fully with TSA locks to allow for quick and easy airport security inspections.

  • Built to last a lifetime: At 15.5-17 kg depending on size chosen, the full aluminium construction is strong, repairable, and durable for a lifetime of trips.

    Frequently Asked Questions

    Will my bike fit in?

    We've built the Stelvio to accept the biggest of long-travel rigs. When it will fit in no other box, it'll fit in this one. It also comes in two sizes, with a shorter version for XC or trail bikes that aren't quite as long travel.

    How long does it take to receive my box?

    Production lead time is 4-6 weeks from the point of order. In the UK, delivery is then usually within 48 hours by a trusted courier like FedEx, DHL, or ParcelForce. For customres in the EU, 4-5 days, and in the US 7-10 days

    Why use aluminium?

    It’s a wonderful sustainable material – extremely strong in the grades we use (mainly 6061, as used on high-end frames and in aerospace applications), light weight (panels are just 0.5mm thick), versatile (we use it as sheet, extrusions, turnings and stampings) corrosion resistant and eminently recyclable. And oh, it looks good too! Plus, we an offer an amazing range of powder coat colours too.

    Will it dent or scratch?

    Yes it will, but only in a good way. And that’s also what makes aluminium such a great material – each cycling journey will add a patina of use and earn the odd distinctive scar but without impacting strength or structure. We like to think we look better with age.

    Of course, no material is indestructible and there is always a balance to be struck between strength and weight. If a panel is breached due to, for instance, wilful neglect on the part of a baggage handler then it would not spell the end for your box – panel repair/replacement is straightforward and supported by the factory.

    Our experience is that a Buxumbox can take far more abuse than moulded plastic or semi-rigid boxes (and is repairable too!)

    I hate packing - please tell me that packing your boxes is painless?

    It’s painless. In fact, making these boxes simple to use, highly versatile and quick to pack is a design fundamental. You don’t need a degree in applied mental gymnastics here – we’re all about these boxes being intuitive to use. The Tourmalet takes less than ten minutes to pack or unpack and the Ventoux under five minutes, with the absolute minimum of disassembly required.

    Will airlines charge for a bike box?

    Probably yes – though policies do vary by airline. And other brands of bike boxes or bags aren't exempt either. The good news is that there is a trend by airlines to offer transparent pricing polices for items of Sporting Goods rather than simply applying excess baggage rules.

    You can normally find policies and rates by searching for "Sporting Goods" or "Bicycles" on your airline’s website.

    Can you produce custom boxes?

    Yes – within certain physical limits and the limits of physics! As well as producing custom sizes and hardware features for large or unusual bikes (even tandems), we can provide custom decals and logos – for an individual individual or a club/team.

    The most popular customisation feature is to have the box powder-coated in a colour of the customer’s choice – examples of recent production can be found on our blog page and Facebook.
