Cycling accessories specs & selection guide materials, logo methods, packaging, MOQ and compliance
Specifying a private label accessory comes down to a handful of decisions: which material, how it is branded, how it is packed, what drives MOQ, and which documentation your market needs. This guide collects the reference points TandemForge uses when quoting helmets, locks, pumps, lights, bags, mounts and e-mobility products. Dimensions and formats given are common requests, not product ratings.
- ABS / PC / EPS, alloy steel, aluminum, nylon, silicone and more
- Logo methods by material
- Packaging options and what drives MOQ
- Export compliance — the general process, no claims
Materials
- EPS (expanded polystyrene) — the energy-absorbing liner in most bike helmets; density chosen per model. EPP is a more resilient foam used in some multi-sport helmets.
- PC (polycarbonate) — thin helmet shells fused in-mold; tough light housings and mirror lenses.
- ABS — thicker hard-shell helmet shells; housings for lights, mounts and lock covers.
- Alloy and hardened steel — lock shackles, chains and plates; floor-pump barrels; bell domes. Grade and heat treatment are specified per SKU.
- Aluminum — pump barrels, bells, light housings, racks; anodizable in colors.
- Nylon and polyester fabrics — saddle bags, chain sleeves, covers (e.g. 190T taffeta, 210D–1680D Oxford); coated with PU or TPU for water resistance.
- Glass-fiber reinforced nylon (PA) — clamps and brackets for mounts, bells and lights.
- Silicone — light straps, phone-mount pads, grips, seat cushions; moldable with logos.
- Gel and memory foam — seat cushion fills.
- Wicker, PE rattan, steel wire, PP — baskets.
- Lithium-ion cells — rechargeable lights, electric pumps, alarm locks and e-bike batteries; regulated for transport.
Logo methods by material
- In-mold decals / water-transfer graphics — helmet shells; full-color, durable.
- Pad printing — curved plastic parts: light and mount housings, lock covers, pump handles.
- Silk-screen — flat or cylindrical surfaces: pump barrels, boxes, fabric.
- Laser engraving — aluminum and steel: bells, pumps, light bodies, lock bodies.
- Anodizing colors — aluminum parts in brand colors.
- Molded / debossed logos — silicone, rubber and plastic parts on larger runs.
- Woven labels, rubber patches, heat transfer, reflective print — bags, covers, sleeves, cushions, straps.
Packaging options
Window color boxes (helmets, lights, locks), blister and clamshell cards (bells, mirrors, mounts), polybag + header card (bags, covers, cushions), kit boxes (helmet + light, lock + mount, repair kits) and bulk packing for factory fitment or fleets. Manuals and warnings in your languages, barcodes and marketplace (e.g. FBA) labels are applied per SKU. Products with lithium cells need battery labels and, for larger packs, dangerous-goods packaging.
Packaging & MOQ
What drives MOQ:
- Platform — an existing design with your logo starts lower than a new mold or structure (helmet shells, lock bodies, mount housings).
- Colors — plastic, coating, fabric and anodizing colors have minimums per color.
- Logo method — molded logos and custom graphics have setup minimums; pad print and labels start lower.
- Packaging — printed boxes and kits have their own minimums; neutral packaging with a label starts lower.
- Documentation — helmet and battery testing for your market adds time and may set a practical minimum per SKU.
- Mixed SKUs — combining categories helps fill a shipment even when each SKU is small.
MOQ and lead time are quoted per SKU on every quotation; no prices are published. Send your RFQ via the inquiry form.
Export compliance — general process
We do not hold out certifications, listings or ratings on this site. Documentation is handled per SKU and per order:
- Brief. You tell us the destination market, sales channel and any retailer, marketplace, insurer or city requirements.
- Identify per SKU. We list which documents may apply. Typical examples: bike helmets — the helmet standard of the market (for example CPSC 16 CFR Part 1203 in the US, EN 1078 in the EU/UK) with testing by an accredited lab, and third-party testing for children’s helmets in the US; lithium batteries (e-bike packs, rechargeable lights, electric pumps, alarm locks) — UN 38.3 test summary, SDS and dangerous-goods packing, and for e-bike batteries the safety standards a market or channel requires (for example UL 2271 / UL 2849 in the US, EN 50604-1 in Europe); electronics — electrical, EMC and radio documents for smart or rechargeable products; children’s products and materials — material and chemical declarations (for example CPSIA, Prop 65 or REACH where relevant); locks — independent security ratings only if a model is submitted.
- Confirm before production. What can be provided — existing reports for a platform, or testing arranged with an accredited third-party laboratory — is confirmed on the quotation for your market, before mass production.
- Labels and claims. Labels, manuals, warnings and packaging claims are approved by your team and must match the documentation for that SKU.
Labeling and claims are the brand owner’s responsibility. Rules change; confirm current requirements with your compliance advisor or laboratory.

General reference for product selection — not product ratings or test results. Documentation is confirmed per SKU and per order for each market.
No certifications, ratings or test data claimed. We describe what each product is made of, how it works and how it can be customized. We do not display certification marks or security ratings, publish test data, factory capacity or customer cases on this site. Test reports and certification documentation can be provided or arranged per order for the buyer’s market, as the brand owner requires. Bike helmets and lithium e-bike batteries are regulated products: the applicable standard (for example CPSC 16 CFR 1203 / EN 1078 for helmets; UN 38.3 transport testing and UL 2271 / UL 2849 / EN 50604-1 for batteries) is confirmed per SKU and per order with the supplier and an accredited lab before production. Labeling and claims are the brand owner’s responsibility.
Frequently asked questions
In-mold or hard-shell helmet — which is better for my range?
In-mold is lighter and more ventilated, typical for road and MTB; hard-shell suits urban and kids’ styles. Many ranges carry both. Compliance is confirmed per SKU either way.
Which logo method lasts longest on aluminum?
Laser engraving and anodizing are the most durable on aluminum; pad print is cheaper for multi-color logos.
Why do lithium products take longer?
UN 38.3 testing, dangerous-goods packing and any market safety testing must be in place before shipment.
What is the MOQ and lead time?
Both are quoted per SKU. MOQ depends mainly on the platform (an existing design vs. a new mold), color, logo method, packaging and the documentation your market needs; lead time depends on customization, documentation and season. Send your quantities and we confirm both on the quotation — see also the packaging & MOQ section of our specs guide.
Do your helmets meet CPSC or EN 1078?
We do not claim that any helmet on this site meets a specific standard. Bicycle helmets are a regulated product: in the US they fall under the CPSC bicycle helmet standard (16 CFR Part 1203), in the EU and UK EN 1078 is the usual reference, and other markets have their own rules. For each helmet SKU and order, the buyer and supplier confirm the target market, the standard, which accredited laboratory tests the exact model and size range, and the resulting certificate and labeling — before mass production. See the compliance process in our specs guide.
Are your e-bike batteries UN38.3 or UL certified?
We do not claim any certification for e-bike batteries on this site. Lithium-ion batteries need UN 38.3 transport test documentation and dangerous-goods (Class 9) packing and labeling before they can ship by sea or air, and many markets or channels require more — for example UL 2271 (LEV batteries) or UL 2849 (e-bike electrical systems) in the US, and EN 50604-1 in Europe. Which documents apply is confirmed per SKU and per order with the supplier and an accredited laboratory, before production. See the compliance process in our specs guide.
Are your products certified or tested?
We do not display certification marks, security ratings or test data on this site. Test reports and certification documentation can be provided or arranged per order for your market, as your brand requires: tell us the destination market, sales channel and the standard or document your retailer or marketplace asks for, and the quotation confirms which documentation applies to each SKU and how it is obtained (existing reports for a platform, or testing arranged with a third-party laboratory). See the export compliance section of our specs guide or ask on the inquiry form.
