What are metal mudguard stickers?
Metal mudguard stickers are flexible, 1 mm thin labels made of aluminium, tin, copper or brass that you stick directly onto the curved surface of a mudguard or bike frame. Unlike ordinary vinyl stickers, these metal labels follow the curve of your bike without wrinkles and give a premium, durable look that lasts for years.
Key features
- Flexible and thin: 1 mm total thickness (including embossing and adhesive) makes the label follow the curved shape of the mudguard exactly
- 3D embossing: Every metal label has a subtle 3D effect that adds depth and a premium look
- Material guarantee: 100% the stated metal, no mix, no coating underneath; aluminium stays stable outdoors and does not discolour
- Self-adhesive and permanent: Mount directly on clean aluminium/steel bike parts; the adhesive is specially calibrated per metal type (yellow Lohmann adhesive for aluminium, 3M for copper/brass)
- Water resistant: Even after rain, snow and salty air the labels remain intact and readable
- Removable later: With a sticker remover the label comes off cleanly without scratches or adhesive residue
- Minimum run 250 units: Unit price starts around €1.27 at 250 units; from 2,500 units it drops to about €0.60
- Lead time 4–5 weeks: After approval of the free digital preview, no physical samples, but a sample pack
Why the curved mudguard needs a metal label
A bike’s mudguard is not flat; it runs in an arc from front to back. An ordinary sticker will go on it, but wrinkles quickly and looks cheap. A 3 mm hard badge would not fit at all: it is as stiff as a pebble and does not follow any curve. This is where the 1 mm metal label comes in. More guides on this topic are in the category Metal labels.
That label bends without creasing. It sits in a sweet spot: thin enough to be flexible, thick enough (with the 3D embossing) to look truly premium. Bike manufacturers and bike shops, we work with more than 500 partners such as BikeTotaal and Azor, almost always choose metal labels on mudguard and frame. An e‑bike quickly costs €1,500 to €3,000. A cheap sticker does not match that. A metal label sets your brand apart from competitors and fits the premium positioning of your bike.
The role of aluminium: your best choice for outdoors
Now you know you want a metal label, the next question: which metal? Schild Inc offers four options, tin, copper, brass and aluminium, but for a mudguard that stays outdoors, aluminium is the recommendation without question. All finishes and prices are on the page bike labels and accessories.
Tin, copper and brass oxidise. Yes, even despite the protective layer we apply as standard. After 1–2 years you will see the edges start to discolour. That can be a vintage look if you want it on purpose (patination), but for bike brand branding it is usually not the goal. Aluminium stays stable. It does not discolour, does not go dark, and looks just as fresh after years as it does today.
From experience we know that bikes are regularly exposed to rain and salty air, think of bikes on the coast or in cities where salt is used on the roads. Aluminium is the choice that will not give you nightmares.
Dimensions and design on the mudguard
A typical mudguard has space for a label of about 50 × 35 mm. That is not arbitrary; it is the spot where the label is clearly visible without getting in the way of cleaning, tyres or the rear wheel. Also read our guide on bike label outdoors.
A common mistake: a square label on a round mudguard. Visually it does not work. A horizontal rectangular format (such as 60 × 30 mm) follows the natural line of the mudguard much better. At Schild Inc you can design the label to size, round, oval, rectangular or even your brand shape, and the digital preview (free with every order) shows exactly how it will sit on your bike before we start production.
The largest labels we make are 180–220 mm; bigger than that becomes tricky logistically. For extra large branding we recommend two smaller labels (for example on mudguard and frame) instead of one gigantic label.
How to attach the metal label to the mudguard
Installation is simple: clean surface, remove the backing and press. The self-adhesive glue is specially chosen. For aluminium we use yellow Lohmann adhesive (German quality); it bonds excellently to the paintwork of the mudguard. The adhesive does not reach full strength immediately; let the label cure for 24 hours before using the bike. For this sector we have a separate page: bike labels and accessories.
A clean mudguard is crucial. Dirt, grease or old adhesive residue drastically reduce adhesion. We recommend first wiping the surface with isopropyl alcohol (available in electronics or cleaning shops) and letting it dry for 5 minutes.
If you want to remove the label later, for example because your brand changes or you sell the bike, use a sticker remover (available at DIY stores). Warm the part, let it soak for a moment, and pull gently. No scratches, no glue stains.
By the way: we also offer a non-standard permanent adhesive option (on request). That label really will not come off, suitable if you are sure you want to keep the brand for life.
Comparison: metal label, vinyl sticker and hard badge
Below you can see how the three options stack up on the mudguard: Also read our guide on bike labels bike shop.
| Feature | Metal label (1 mm) | Ordinary vinyl sticker | Hard badge (3 mm) | |---|---|---|---| | Material | 100% aluminium/tin/copper/brass | PVC/vinyl with self-adhesive backing | Coloured zinc alloy | | Flexibility | Bends with mudguard | Limited flexibility, wrinkles quickly | Completely rigid, does not fit a curve | | Outdoor durability | Aluminium: stays stable for years | Fading after 1–2 years in sunlight | Zinc alloy: stable, but mounting is difficult on a curved part | | 3D effect | Yes, subtle embossing | No, completely flat | Yes, more pronounced | | Removal | Clean and traceless with sticker remover | Adhesive residue/scratches left behind | Permanent mounting with screw/bolt | | Suitable for mudguard | Ideal: flexible, premium, durable | Yes, but looks less premium | No, too rigid for the curvature of the mudguard |
Who are metal mudguard stickers suitable for?
Bike manufacturers and brands
Your bike looks exclusive with a metal brand label. At a price of around €1.27 per label (at 250 units) and economies of scale to €0.60 per piece (from 2,500 units) you can easily build this into your production chain. Schild Inc has produced over 800,000 metal labels since 2021 for more than 1,200 business customers in 19 countries, many of these are bike brands doing exactly this.
Bike shops and custom builders
You add value to the bikes you sell. A local bike shop can add a house-style label to every model that comes in. That sets your stock apart from chains and gives customers the feeling they bought something special. Minimum run is 250 units, so even for smaller shops this is achievable. More background on aluminium can be found on Wikipedia.
Private label and vintage restorers
You restore old bikes or build your own vintage collection. A metal label (for example with a retro font and tin/copper with patina effect) fits perfectly on a classic bike. Aluminium is also an option; it looks modern and clean.
Practical tips from experience
Tip 1: Choose the right moment for installation. Apply the label when the bike is finished, not halfway through assembly. Grease and dust during assembly do not bond well.
Tip 2: Review the preview digitally beforehand. We create a free digital preview in which we place your label on your bike photo (with your own design). That avoids disappointment.
Tip 3: Plan the installation carefully. Lead time is 4–5 weeks after approval. If you need labels for a season start or campaign, order in time.
Tip 4: Aluminium for outdoors, other metals for décor. Do you want a limited edition bike with a patina look? Choose tin or copper and accept that it will discolour. Do you want a bike you will still admire in years to come? Aluminium.
Water resistance and weather resistance
A mudguard is always outdoors. The label adhesive is tested for rain resistance, but it goes further: the metal itself withstands rain, snow, sand and UV far better than vinyl. A vinyl sticker fades quickly in intense sunlight; the colours become hazy. A metal label (especially with a printed top layer) retains its sheen. The adhesive under the label is not weakened by water. Schild Inc uses specific adhesive systems per metal, Lohmann for aluminium, 3M for copper/brass, because these brands have decades of outdoor experience in the automotive and shipbuilding industries.
After rain you can simply wipe the label clean with a cloth. No special care needed.
Design and 3D effect
The 3D embossing is not only attractive, it also provides contrast. Where your logo or brand stands up in relief and the flat parts have more shine, the letters stand out much more strongly. That depth makes your label feel not like a “sticker”, but like part of the bike itself.
In design we recommend: keep font sizes above 8 pt (smaller becomes unclear with embossing), use strong contrasts between letters and background (especially important with tin or copper that can develop patina), and first test your logo at 1:1 on paper on your bike’s mudguard. That way you see whether the dimensions are right.
Minimum run, price and planning
Technically, metal labels can be produced below 250 units, but the price then increases considerably. At 100 units you quickly pay €3–€5 per piece. At 250 units you drop to €1.27 (depending on size and shape). That 250 threshold is economic. Hard badges cannot go below 250 units at all; they always start at 250.
The price depends on: size, shape (round is more expensive than rectangular), metal type (aluminium is more affordable than tin/copper), and whether you want printing. For an estimate: use the pricing calculator on our product page or request a quote. We almost always give two variants: budget option (embossing and colour only) and premium option (with printed brand detail).
Lead time is 4–5 weeks once you have approved the digital preview. That is standard; we produce in Europe (Schild Inc is in Almere), not in Asia, so no surprises at customs.
Conclusion
Yes, metal mudguard stickers are the right choice if you want to build a premium bike brand or give your bikes a durable brand mark. The 1 mm flexibility follows the curve of your mudguard without wrinkles, aluminium stays stable outdoors, and the 3D embossing gives a professional look that vinyl stickers cannot match. With a minimum run of 250 units the price starts around €1.27 per piece, a low-threshold investment for small to medium series.
Removability also makes it low risk: you can experiment, adjust your brand or ship your bike later without permanent scars. Schild Inc has been producing these labels for years for bike manufacturers and shops in Europe, and 95% of our customers order again.
