Answers collected from our product and program pages. TandemForge supplies businesses only — bike, e-bike and e-scooter brands, bike shops, retailers, distributors, e-commerce sellers and shared-mobility operators. For anything not covered, use the inquiry form.
Ordering, OEM & wholesale
Does TandemForge sell to consumers?
No. We are a B2B supplier for bike and e-bike brands, e-scooter brands, bike shops, sporting goods retailers, distributors, e-commerce sellers and shared-mobility operators. Riders should buy from our customers’ retail channels.
What is the minimum order quantity?
MOQ is quoted per SKU and depends on the platform, color, logo method, packaging and documentation. Mixed orders across categories are welcome — see wholesale and the packaging & MOQ section of our specs guide.
Can I put my own brand on the products?
Yes. Pad-printed, laser-engraved, molded or woven logos, custom colors, inserts and retail packaging are covered in our OEM & private label program.
Are your products certified?
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. Helmets and lithium e-bike batteries are regulated: the applicable standard is confirmed per SKU and per order with the supplier and an accredited lab before production.
Do you supply shared-mobility and rental fleets?
Yes — locks, phone mounts, lights, bells, baskets and other wear parts in fleet quantities, with your fleet branding. See electric scooter accessories and wholesale.
How fast do you reply to inquiries?
Typically within 24 hours on working days. Use the inquiry form.
What is the minimum order for private label?
MOQ is quoted per SKU and depends on how much is customized — an existing platform with your logo starts lower than custom colors, molds or printed retail boxes.
Can I mix categories in one order?
Yes. Mixed orders across helmets, locks, lights, bags and other categories are common; each SKU is quoted separately.
Who is responsible for the claims on our packaging?
The brand owner. We print the content your team approves and supply the documentation arranged for each SKU; we do not originate ratings or performance claims.
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.
Do you have price tiers?
Yes, pricing is tiered by quantity per SKU and confirmed on quotation. No prices are published on this site.
Do you supply shared-mobility fleets?
Yes — fleet-branded accessories in bulk and spare-part quantities, with delivery schedules agreed per order.
Which markets do you serve?
This site focuses on the US market; we also quote other destinations. Tell us your market and its requirements.
How do I get a catalog?
Request it through the inquiry form with your business details.
Bike Safety
Can I order helmets, lights and bells in one shipment?
Yes. Mixed orders across safety items and other categories are common; each SKU is quoted separately.
Do you make bundles for new-bike programs?
Yes — light sets, bells and mirrors packed for factory fitment or as an add-on bundle, under your brand.

Bike Helmets
What is the difference between in-mold and hard-shell helmets?
In-mold helmets fuse a thin PC shell to the EPS liner during molding, giving a lighter, more ventilated helmet. Hard-shell helmets attach a thicker ABS shell to the liner and are common for urban and kids’ styles.
Can I change the color or graphics of an existing tested model?
Usually yes — color and graphics changes are normally possible on an existing model. Any structural change (shell, liner, vents, size) can require new testing; this is confirmed per SKU before sampling.
Do you make kids’ helmets?
Yes, in smaller size runs with kid-friendly graphics. Children’s helmets carry extra documentation duties in many markets (in the US, third-party testing at a CPSC-accepted laboratory), confirmed per order.
Can you add a rear light to the helmet?
Yes — integrated or clip-on USB-rechargeable rear LEDs are available on selected models.
Bike Lights
How bright are your bike lights?
Output is specified per SKU to your target price point and market, and confirmed with test documentation per order. We do not publish lumen or runtime figures on this site.
Can you supply lights powered by the e-bike battery?
Yes, specified to match the motor system’s voltage, connector and wiring; tell us the system you use.
Do you have lights approved for Germany (StVZO)?
Road-traffic approvals belong to specific models. If you need StVZO or another national approval, it is confirmed per SKU and per order; none is claimed here.
Bike Bells
Which bell is loudest?
Steel domes generally ring brighter and brass domes warmer; we recommend choosing on samples. No sound-level figures are published here.
Do your bells fit e-scooters?
Yes — scooter versions with clamps for scooter stems and handlebars are available, popular with fleet operators.
Can you engrave our logo on the dome?
Yes, laser engraving or printing; custom dome shapes on larger runs.
Bike Mirrors
Convex or flat lens?
Convex lenses show a wider field; flat lenses show true distance. Many buyers offer both; we recommend comparing samples.
Do you supply mirrors for e-scooters?
Yes — scooter-specific clamps and arms, popular with fleet operators.
Can mirrors be folded when parked?
Yes, folding-arm versions are available to reduce breakage.
Bike Security
Which lock should a bike shop stock?
Most shops carry a U-lock and a chain or folding lock for main locking, plus a cable lock as a secondary or budget option.
Can locks be keyed alike for a fleet?
Yes, keyed-alike and master-key systems are available on selected cylinders, quoted per order.
Do your locks carry Sold Secure, ART or similar ratings?
No security rating is claimed on this site. Independent ratings such as Sold Secure (UK) or ART (Netherlands) belong to a specific tested model; if your channel needs one, the model is submitted to that scheme per order and the rating may only be printed once it is granted. Shackle diameter, steel grade and cylinder type are specified per SKU — we publish no break-time or attack-resistance figures.
