A bike brand in the Netherlands ordered 1,200 city ebikes from a Chinese factory last spring. The factory sent a glossy brochure, an MOQ table, and a price list with three motor options. The brand signed, paid a 30 percent deposit, and waited. Eight weeks later the factory shipped a bike with a different battery brand, a controller they had never tested, and no EN 15194 paperwork. The bikes sat in a Rotterdam warehouse for two months while the brand chased certificates. The importer finally paid for new batteries out of his own pocket.
That story repeats more often than factories admit. Buying an OEM electric bike is not buying from a catalog. It is a contract with a factory that builds your brand name onto someone else's production line. Nobody checks this until the container lands, and by then it is too late. This guide covers what to check before you sign: certifications, locked specs, MOQ, tooling ownership, and how the factory handles changes after the deposit clears.
Why OEM Electric Bike Buying Is Different
When you buy stock bikes, the risk sits on the factory's shelf. When you order an OEM electric bike, the risk sits on your name. Your logo goes on the frame. Your spec sheet goes to customs. Your customers complain to you, not to the factory.
I keep telling brands the same thing: your name is on the frame, so the spec is on you. You are not comparing prices. You are comparing who holds each risk: certification, battery supply, motor firmware, packaging compliance, after-sales parts. Write down who holds what, in an email, before you sign anything.
Certifications: Who Files and Who Pays
The certificate question decides whether your batch clears customs or sits at port. EN 15194 for Europe, UL 2849 for the US market, CE, UKCA, and local battery transport rules. Some factories hold certificates for their own models. That does not cover your OEM electric bike with your brand name and your battery spec. The certificate is not decoration. It is the gate.
Ask three questions. Which certificates does this exact configuration hold? Who re-runs the test when we change the battery or the motor? And who pays for the retest? A factory that shrugs at these questions is a factory that will shrug at your shipment.
Lock the Spec Sheet Before the Deposit
An OEM electric bike spec is a contract, not a suggestion. Nothing about an OEM electric bike is too small to write down. Write every part down in numbers.
Motor. Hub or mid-drive, nominal watts, peak watts, rated voltage. 250W hub and 750W hub are not the same part.
Battery. Cell brand, chemistry, Ah, and nominal voltage. "48V 15Ah" is a label, not a spec. Ask for the cell datasheet.
Controller and display. Which controller, which protocol, which display firmware. A firmware that locks at 25 km/h in one market and 32 km/h in another is a firmware decision you should make, not discover.
Brakes, tires, rims, saddle, lights. Write the brand or the part number for each. The gap between "what we quoted" and "what we shipped" lives in the unlisted parts.
Sensors. Torque sensor or cadence sensor changes the ride feel completely. Confirm it in the spec, because it is one of the most expensive silent changes a factory can make.
Contracts: MOQ, Samples, Payment, and Tooling
MOQ is where most first-time OEM electric bike buyers guess wrong. Ask how the MOQ breaks down. 100 units of one model is different from 100 units across five colors. Ask for a pre-production sample and agree what the sample confirms. Frame geometry, battery placement, wiring routing, decal position. Pay for the sample. A paid sample changes the relationship.
Payment terms are part of the spec too. 30 percent deposit and 70 percent before shipment is common. Some factories want 100 percent before shipment. Neither is wrong, but the split should reflect who carries the risk at each stage. Get the payment schedule in writing with clear milestones.
Custom frames mean molds. Ask who owns the mold, what it costs, and what happens when you stop ordering. Mold ownership is the difference between a long-term OEM electric bike partnership and a one-off purchase. Same for tooling and dedicated fixtures. Write the ownership and the buyout price into the contract. Factories change names, owners, and priorities. Your mold should not change with them.
Audit the Factory Before You Sign
Photos and videos are marketing. Walk the line, or pay a third party to walk it. The audit is the cheapest part of any OEM electric bike program.
Check the test equipment. A factory that cannot show a battery cycling test, a motor test bench, or a brake test rig cannot verify what they ship. Check the spare parts flow. Ask how long after your first batch they will still supply replacement parts for that model.
Ask for reference buyers. Two or three brands that have run OEM electric bike programs for more than a year. Call one. A factory that cannot give you a live reference is a factory that has not done the job before.
FAQ
What is an OEM electric bike? A bike built to your brand, your spec, and your packaging, on a factory production line that carries your name rather than a catalog model.
How much does OEM electric bike development cost? Budget for the sample, the mold or tooling if you need a custom frame, certification retests, and the deposit. Numbers vary widely by configuration.
Who holds the certifications? The factory holds what they tested. Your brand holds what they did not test. Confirm every certificate against your exact configuration.
What is a good MOQ for an OEM electric bike? Typically 50 to 300 units depending on the factory and the model. Confirm the split across models and colors in writing.
How do I protect my design? Sign an NDA, agree mold ownership, and keep the firmware and battery spec confidential in the contract.
Send Your Spec and Get a Feasibility Check
An OEM electric bike works when the factory and the brand agree on the same numbers.
Send us the model, the wattage, the battery spec, the target market, and the volume. Our engineers will reply with a feasibility check: which certificates apply, what the MOQ looks like, and where the tooling cost lands. Browse our electric bike range, check the fat tire electric bikes for high-power builds, or look at the electric motorcycles for faster platforms. Use the contact page to send the spec sheet, and we will come back with numbers you can compare.
