​Affordable commuting: Xcase 3-in-1 cycle bag – pannier and rucksack in one

Bags for bike panniers are no longer just for day trips and cycle tours; they’re just as suitable as shopping bags or for the daily commute to the office. The cycling market now offers a growing range of bike bags that can be converted into rucksacks once you reach your destination – hybrid models that are becoming increasingly popular.

​Multifunctionality as a concept – nothing new, but increasingly relevant

A flexible solution with internal pockets is recommended for the journey to work. This is precisely the market segment that the mail-order company Pearl is now targeting with its own-brand range, Xcase. The new 3-in-1 cycle bag has recently become available – at a price that’s sure to turn heads.

What the Xcase offers: three carrying options, one product

The Xcase 3-in-1 cycle bag combines a pannier, rucksack and shoulder bag in a single product. Once you’ve parked your bike at your destination, you can switch how you carry it without having to repack – ideal for your commute, shopping trips or spontaneous cycle rides.

The integrated shoulder straps transform the bag into a rucksack, whilst the adjustable and detachable shoulder strap (up to 139 cm in length) allows it to be used as a shoulder bag, as is common with many classic panniers.

Handy: The 3-in-1 cycle bag features a removable, lightly padded inner laptop compartment with two additional slip pockets, secured with a Velcro fastening. So if you’re just popping into a café or rushing to the office, you can take the padded laptop compartment with you separately, whilst the rest of the contents stay on the bike.

A light-reflecting logo and reflective strips on the shoulder straps improve visibility in traffic at dusk and in the dark, although not in all directions. Side reflectors, which would improve visibility to the left and right at the back and to the front and rear on the luggage rack, are missing here.

Capacity and storage space: Designed for commuters

The 25-litre capacity offers ample storage space for commuters and touring cyclists. There’s plenty of room for a laptop, documents, a change of clothes or a large weekly shop. As well as the padded inner pocket, a side mesh pocket and a zipped outer pocket provide additional, well-organised storage space for items you need to access quickly.

The external dimensions of the pannier are 33 × 60 × 16 cm; the removable inner pouch measures 28 × 38 × 4.5 cm, which is big enough for at least a thick 15-inch laptop. Weighing 1,452 grams, the Xcase is by no means a lightweight – and those who get hung up on every gram are usually in the wrong when it comes to all-in-one solutions anyway.

The TPU version offers slightly less storage space. At 20 litres, it holds about one head of lettuce less, but the strap system, construction and inner compartment are largely the same. Weighing 1,200 grams, this saves a good 250 grams compared to the slightly larger PVC bag. The manufacturer’s stated dimensions for the Xcase 3in1 20L are: 28 × 56 × 14 cm.

Fastening: click system plus Velcro tape

A tool-free click system and an additional Velcro strap ensure the bag stays securely attached to the luggage rack. The hooks click into place on the luggage rack tube and can be released again in just a few simple steps once you reach your destination. This is solid, everyday technology – albeit of the most affordable variety and in no way comparable to the hook systems found on premium-class luggage rack bags. No maximum load capacity is specified.

Water resistance: Robust, but not certified

The hard-wearing material reliably protects your laptop, documents, clothes and shopping from rain and splashes. The outer material is made up of 85 per cent PVC or TPU and 15 per cent polyester, and is heat-sealed at the joints – there are no seams. It usually holds up well.

Where loops or tabs are sewn on, heat-sealed pads seal the seams from the inside, and a roll-top closure usually keeps the bag watertight as well. Even the zips on the outer pockets are protected against water ingress. This should mean the Xcase fulfils its purpose on typical rainy days – although no certified IPX waterproof rating is specified.

In focus: A comparison of materials – TPU vs. PVC

The Xcase 3-in-1 cycle bag, with a capacity of 25 litres, is made primarily from PVC, whilst its smaller counterpart, with a capacity of 20 litres, is made from TPU – thermoplastic polyurethane. A difference that means more than just an entry in the technical specifications.

TPU has made a name for itself in the outdoor industry thanks to its exceptional durability, flexibility and relative environmental friendliness, whilst PVC has been a standard material in the industry for decades – valued above all for its affordability, durability and abrasion resistance.

These material properties are of direct relevance to cycle bags that are exposed to wind and weather on a daily basis. TPU remains flexible even at extreme temperatures and performs reliably from −50 °C to 120 °C; PVC, on the other hand, becomes brittle below 0 °C and softens above 60 °C, which limits its use in certain environments.

When it comes to durability, the balance continues to tip in favour of TPU: under normal everyday or outdoor conditions, TPU-based waterproof bags typically last longer. The cheaper PVC bags can, if you’re unlucky, become stiff or crack quite early on – particularly in cold climates or when exposed to intense UV radiation.

Added to this is the sustainability aspect: PVC can release toxic chemicals during the manufacturing process and when incinerated. In contrast, TPU fabric is considered a more environmentally friendly alternative, as it is made from non-toxic materials and can be recycled. TPU also complies with international environmental standards such as EU REACH, CPSIA and California Prop 65.

The clear advantage of PVC, on the other hand, lies in its price: PVC bags cost less than bags made from TPU or high-quality nylon – PVC is easy to manufacture, which is why manufacturers can offer lower prices.

Conclusion on the material: Anyone who uses the Xcase on a daily basis, all year round, should seriously consider paying the extra cost for the 20-litre TPU version – it is likely to be more durable and environmentally friendly under everyday conditions. For occasional or seasonal use, however, the 25-litre PVC version offers better value for money.

Positioning in the market: Clearly cheaper than others, conceptually on a par within certain limits

If you’re looking for a similar 3-in-1 design, you’ll find them, for example, from Ortlieb, Deuter or even Forrider from Berlin (reviewed here in BIKE). At the very least, the first two are clearly in a league of their own. In terms of price, but they also offer greater detail, higher-quality workmanship and greater comfort.

These expert-designed rucksacks generally feature padded back systems, additional helmet compartments and, in some cases, the option to easily retrofit a waist belt. You won’t find any sharp edges or stiff zips in the premium range either.

Conceptually, however, the Xcase and Forrider bags are quite similar: classic, robust PVC tarpaulin, a similar amount of storage space, 3-in-1 functionality, a click-fastening system, and a padded, removable laptop pocket. However, when used as rucksacks, these largely unpadded multi-functional models are really only intended for short journeys – a point worth noting for commuters and occasional day-trippers, particularly when the bags are loaded with shopping.

The key difference with the online discount bags lies in the price – at 36.99 euros, the Xcase PVC bags cost a good 25 euros less than the already affordable Forrider bags. Even the version made from TPU, which tends to be more durable, is still well below that at just over 47 euros.

Conclusion: A practical everyday tool offering clear value for money

The Xcase 3-in-1 PVC cycle bag costs 36.99 euros at pearl.de. If you cycle to work every day, do the shopping from time to time and aren’t looking for premium quality, this is a functional item for you.

The padded, removable laptop pocket is a welcome bonus compared to fixed, sewn-in ones; a minimum number of reflective elements sensibly enhances safety; the click system works well – and a capacity of 20 to 25 litres is sufficient for most everyday situations.

On the other hand, if you’re out and about all year round in all weathers, care a bit more about the look and want to carry a bit less weight, you should consider paying the extra for the TPU version. This even more durable material, with its matt black finish, doesn’t immediately bring to mind lorry tarpaulins, and it’s a good 250 grams lighter. One thing applies to both: you’d be hard-pressed to find better value for money at the moment.
