Question 1

What makes the JB-TDN26Z-F different from a standard 20-inch fat tire folding e-bike?

Accepted Answer

The range figure. Most 20-inch fat tire folders trade grip for consumption, and the spec sheet ends up in the 40 km class. The JB-TDN26Z-F pairs a 48V 350W motor with a 48V 14Ah LG battery, specified at up to 75 km per charge, which is a different range class for this wheel and tire size.

Question 2

How does a 20×4.0" fat tire build reach 75 km per charge?

Accepted Answer

Three factors work together: a 48V 14Ah LG pack rated at 672Wh, a 350W motor specified for efficiency rather than peak output, and a Shimano 7-speed drivetrain that lets the rider keep the motor in its efficient band on gradients. Range is confirmed with you at the specification stage against rider weight, terrain, and assist level.

Question 3

What battery does it use, and can we change the capacity or cell brand?

Accepted Answer

The standard build uses a 48V 14Ah LG battery rated at 672Wh. Capacity and cell brand can be adjusted to your range target and price tier, and mounting position, lock, and charge-port location are reviewed at the same time.

Question 4

Can the speed configuration be set for our market?

Accepted Answer

Yes. The platform is supplied at 32 km/h, and the limit is configured during specification to match your market's regulations. Motor output is reviewed against the same requirement, and the controller mapping is documented in the programme file.

Question 5

Are 20×4.0" tires and replacement parts easy to source in our market?

Accepted Answer

20×4.0" is a widely stocked size, and we supply tread pattern, compound, puncture protection, and reflective-sidewall options from the factory so your first order and your service stock come from the same source. Tires, tubes, brake pads, and chains are included in the spare-parts programme.

Question 6

How is the folding joint engineered for the loads of a fat tire build?

Accepted Answer

A wider tire increases rolling resistance and the load going into the rear triangle, and the folding joint sits inside that load path. Hinge plates are laser-cut to drawing, hinge seats and dropout faces are welded at robotic stations with dedicated fixtures, and the assembly is heat-treated to T4/T6. Reinforced fatigue cycles on the folding joint and rear triangle are run in our laboratory before a batch is released.

Question 7

Which rider segments and sales channels does this model suit?

Accepted Answer

Coastal and lakeside rental operators, resort and holiday-park fleets, riders in regions with snow or unpaved routes, and urban riders who want the stability of a wide tire. It fits retail, e-commerce, and fleet channels where one frame has to cover several rider segments, and where the range figure on the carton is part of the buying decision.

Question 8

What does the quality process cover before a batch is released?

Accepted Answer

Production runs under our ISO9001-certified quality system and 6S management. Frame fatigue, braking performance, electrical safety, and folding-joint durability are verified in our in-house laboratory, and test reports and batch inspection records are issued before release. Where your target market requires specific certification, we review it with you during project specification.

Question 9

Can we start with a pilot batch, and how is EU delivery handled?

Accepted Answer

Pilot batches are available to validate demand before volume orders. A pre-production sample is built to your locked specification for approval and testing, CKD/SKD kits are available to reduce freight per unit, and assembly can be scheduled at our Poland facility for EU-focused programmes.

Question 10

What does the spare-parts programme cover for a fat tire folder?

Accepted Answer

Long-term availability for fat tire-specific components such as 20×4.0" tires and tubes, reinforced spokes, and folding-joint hardware, alongside wear parts and electrical components, supported by technical documentation and parts manuals for your service network.
