YOXUFA Motorized Bicycle Ignition Coil & Magneto Kit — 49–100cc 2‑Stroke, CDI with Light & Aluminum Magneto

YOXUFA's motorized bicycle kit is a complete ignition and magneto replacement set designed to restore spark and fuel line reliability on 49–100cc 2‑stroke engines.

This kit bundles a CDI ignition coil, an aluminum‑sheathed magneto coil, a spark plug, fuel line and filters, plus mounting clips — all intended to make diagnosis and repair faster for motorized bicycles and small 2‑stroke motors such as 49cc, 50cc, 80cc and 100cc units. The magneto's rust‑resistant exterior and the ignition coil's lighted indicator help you confirm electrical operation at a glance. Below you'll find concise answers to common buyer questions and a clear list of what this kit supplies and how it fits your engine.

Will this kit fit my 2‑stroke motorized bicycle?

YOXUFA designed the kit to be compatible with many 49cc–100cc single‑cylinder 2‑stroke motors used on motorized bicycles and small gas motors. Compatibility depends on physical mounting points, plug wire routing and connector types, so measure and compare with your original parts before ordering.

• Engine range: 49cc, 50cc, 80cc, 100cc 2‑stroke units
• Common applications: motorized bicycle models including PK80, BT80, YD100 and similar
• Verify fit: match mounting holes, coil dimensions and plug lead length

How does the ignition coil's lighted section help troubleshooting?

The built‑in illuminated section on the CDI ignition coil provides a quick visual check of whether the ignition is producing a spark when cranking the engine. This reduces guesswork during diagnostics and speeds up repairs, especially when testing wiring or switch connections.

• Visible indicator: confirms coil activation during engine cranking
• Speeds troubleshooting: identifies electrical faults without disassembly
• Useful for roadside checks and first‑time tuners

What are the construction features that improve durability and starting?

The magneto coil features an aluminum outer casing to resist rust and corrosion common on exposed bike parts, while heavy‑gauge copper windings provide a stronger charge for more reliable starts. The kit also includes basic fuel plumbing parts so you can address both ignition and fuel delivery at once.

• Aluminum exterior: corrosion resistance for longer service life
• Thick copper wire windings: easier starting and consistent spark
• Included fuel line and filters: refreshes aged fuel delivery components

What exactly comes in the box and what should I check before installation?

The kit ships with the key ignition and fuel components needed to refresh a small 2‑stroke powerplant: magneto coil, CDI ignition coil with light, spark plug, fuel line, two fuel filters and four mounting clips. Before installing, compare the supplied parts to your original items for connector types, thread sizes and physical fit.

• Packing list: magneto coil, CDI coil, spark plug, fuel line, 2 fuel filters, 4 clips
• Pre‑install checks: verify thread pitch on spark plug and coil mounting spacing
• Tools typically required: basic socket set, pliers, screwdrivers, dielectric grease

Who is this for: This YOXUFA kit is aimed at DIY mechanics, vintage motorized bicycle restorers and small engine owners who want an affordable, all‑in‑one ignition and fuel line refresh for 49–100cc 2‑stroke motors. If you need a plug‑and‑play replacement for worn coils and tired fuel hoses, or you want a quick way to verify ignition during troubleshooting, this kit provides the core parts needed to get your motorized bike firing again. Remember to compare the supplied part dimensions to your original components to ensure compatibility before purchase.
