Question 1

What makes the JB-TDN50Z a utility platform rather than a cargo or a city bike?

Accepted Answer

It is engineered to do three jobs from one frame — carrying loads on the rear rack, carrying a passenger on the footboard and seat position, and everyday riding. A dedicated cargo bike is optimised for freight volume; a city bike is optimised for weight. This platform sits between the two, which lets you cover all three listings with one certified frame.

Question 2

Can the same frame be sold as both a carrier and a passenger bike?

Accepted Answer

Yes. The rear structure is prepared for either use: rack and pannier fittings for cargo duty, or footboard and passenger seat for carrying a second rider. We build both variants on the same line, so you can split a container across two positionings.

Question 3

Should we specify a single battery or a twin-battery setup?

Accepted Answer

One 48V 15Ah LG pack covers everyday riding; two take the platform to roughly 90 km for full-day duty. The choice is a price-point decision rather than an engineering one — the frame, mount and harness are the same, so you can offer both as good/better options in your catalogue.

Question 4

Which component brands can we specify?

Accepted Answer

You can specify manufacturers across the motor, drivetrain, brake, tire and electrical systems — including names already familiar to your service network such as Bafang, Shimano, LG, Samsung, TEKTRO and CST — and we source against that BOM.

Question 5

Why a torque sensor, and can we switch to speed sensing?

Accepted Answer

Torque sensing delivers assist in proportion to pedal input, which is the behaviour expected in EN15194-aligned markets and is noticeably smoother with a loaded rack. Where a price point or market calls for speed sensing, we build that instead — it is a configuration choice, set per programme.

Question 6

Do you supply documentation for EU compliance on this model?

Accepted Answer

Production follows ISO9001 processes with EN15194-aligned testing procedures, and each platform is built with documented compliance for its destination market. Share your target country at enquiry stage so we can align configuration and paperwork accordingly.

Question 7

Can the assist mapping and speed setting be matched to our market's rules?

Accepted Answer

Yes. Assist levels, display language and the speed ceiling are set to the regulation applying in your destination and locked per programme, so every unit in the batch ships consistent.

Question 8

Do you support EU assembly in Poland for this model?

Accepted Answer

Yes. European-focused programmes can be finished on our Poland assembly line, shortening delivery into the EU and reducing exposure to EU anti-dumping duties, alongside CKD/SKD supply where you prefer local assembly.

Question 9

What does an ODM utility project look like from first sketch to shipment?

Accepted Answer

We start from your use case and spec sheet, lock frame geometry and the rear-end configuration, build a pre-production sample for your approval and testing, then move to mass production in Jinhua — with EU final assembly in Poland available for European programmes.

Question 10

How are spare parts and service documentation handled after delivery?

Accepted Answer

We run a structured spare-parts programme with long-term availability on electrical, brake and drivetrain components, and supply parts manuals and technical documentation so your distributors and workshops can service the fleet.
