Electric Motorcycle Main Wiring Harness Assembly — Heavy-Duty Converter & High-Power Supply Cable

Product Overview

Description

The Electric Motorcycle Main Wiring Harness Assembly is a full-bike chassis harness that ties together every electrical node on a modern e-moto, e-scooter, or EV two/three-wheeler. From the battery output through the motor controller, throttle, brake levers, instrument cluster, headlight and taillight, turn signals, horn, charging port, and accessory loads — the main harness is the single most complex assembly on the vehicle, and the part most often customized per bike model. Pure copper conductors with UL recognized PVC insulation, cold-press crimped terminals, and corrugated split conduit deliver the long service life that fleet operators and consumer-class OEMs expect.

Four build variants ship from this product family. The main chassis harness wraps every node in a single tidy bundle with consistent connector pin-out per drawing. The heavy-duty variant integrates a central fuse box, rubber-boot connector entries, and IP67-sealed mating faces for high-power scooters, cargo trikes, and three-wheelers exposed to road spray. The high-power supply cable handles headlight feed and the high-current motor-controller power loop. The dedicated vehicle connector kit supplies D-Sub, KET, Molex, JST, and Sumitomo mating connectors pre-terminated on flying leads for in-line splicing.

We support all common e-moto voltage platforms — 48 V / 60 V / 72 V consumer-class systems and 96 V / 110 V+ high-performance e-moto platforms. Production runs on a fully automatic cold-press line with each terminal 100% pull-tested at rated load and a 1500 VAC / 1-minute high-voltage withstand check before packing. Production is under IATF 16949 and ISO 9001 quality systems. Send a sample harness, photo, BOM, or bike model — we reverse-engineer or build-to-drawing and ship a working sample in 10–15 days.

Key Features

Why This Harness

01

Complete Bike Harness

Single integrated assembly covers every node — battery, controller, throttle, brakes, lights, horn, instrument cluster, charging port.

02

Heavy-Duty Fuse Box Variant

Central fuse box with rubber-boot connector entries — protects the system against shorts and simplifies field service.

Corrugated Conduit Protection

Split loom tubing wraps bundled wires for abrasion and impact resistance — survives two-wheeler vibration and road debris.

04

Multi-Connector Compatibility

Drop-in mating with KET, Molex, JST, Sumitomo, D-Sub — pre-terminated leads match your existing bike-side sockets.

05

48 V – 110 V+ Platforms

Consumer 48/60/72 V scooters through high-performance 96/110 V+ e-moto — wire gauge sized to current draw per drawing.

06

UL Wire · V0 · Cold-Press

UL recognized wire, V0 flame retardant (UL 94), pure copper cold-press terminals, 100% pull-tested, IATF 16949 quality.

FAQ

Frequently Asked Questions

What variants ship from this electric motorcycle harness line?

Four standard build variants ship from the same product family: (A) main chassis harness — complete bike wiring from battery to controller, headlight, taillight, instrument cluster, and accessories; (B) heavy-duty variant with central fuse box and rubber-boot connectors for high-power scooters and three-wheelers; (C) high-power supply cable for headlight and motor controller feed; and (D) dedicated vehicle connector kit with D-Sub, KET, Molex, JST mating per drawing. Every harness is OEM-tailored to the bike model.

Which electric vehicles is this harness designed for?

The harness family fits electric motorcycles, electric scooters, e-mopeds, e-bikes, electric cargo trikes, last-mile delivery scooters, and other EV two- and three-wheelers. Both 48V / 60V / 72V consumer-class systems and 96V / 110V+ high-performance e-moto platforms are supported. We accept OEM drawings and reverse-engineer from a sample harness if no documentation is available.

How is the harness protected against weather and vibration?

Corrugated split conduit (loom tubing) wraps the bundled wires for abrasion and impact resistance; rubber sealing boots protect connector entries from water spray and mud; sealed connectors (KET, Molex, Sumitomo) hit IP67 where required. Critical splices use heat-shrink with adhesive lining. All cable routing follows two-wheeler vibration profiles — strain reliefs at every connector entry, P-clip mount points to drawing.

Is the wire certified and flame retardant?

Yes. The wire is UL recognized with V0 flame-retardant PVC insulation (UL 94 V0). Pure copper conductors are cold-press crimped on a fully automatic line — 100% pull-tested at rated load with a 1500 VAC / 1 minute high-voltage withstand check before packing. Materials meet RoHS and REACH. Production runs under IATF 16949 and ISO 9001 quality systems.

What is the MOQ, lead time, and pricing model?

MOQ from 10 pcs for prototype and pilot runs; typical OEM volumes are 200+ pcs per model. Sample lead time is 10–15 days from drawing approval (e-moto harnesses are complex assemblies); mass production is 20–30 days. Default packing is 40 × 30 × 25 cm carton, ~1.5 kg per assembled harness. We quote within 24 hours from a photo, sample, or bill of materials.
