YOXUFA Motorized Bicycle Ignition & Magneto Coil Kit for 49–100cc 2-Stroke — CDI with Lighted Test, Aluminum Magneto

YOXUFA's motorized bicycle kit is a plug-and-play ignition and magneto coil set designed to restore reliable spark and fuel delivery on 49–100cc 2-stroke motorized bikes.

This replacement kit is built for small 2-stroke engines—common on 49cc, 50cc, 80cc and 100cc motorized bicycles—and bundles the essential ignition and fuel-line components you normally replace together. It combines a CDI ignition coil with a magneto coil, spark plug, fuel line and filters, plus mounting clips so you can quickly swap worn parts and get the engine firing again without hunting for single components.

What exactly comes in the YOXUFA ignition and magneto kit?

The kit includes a matched set of electrical and fuel parts to replace the most failure-prone items on a 2-stroke motorized bicycle. Everything ships together so installation is straightforward.

• 1 magneto coil (aluminum housing to resist corrosion)
• 1 CDI ignition coil with illuminated test section
• 1 spark plug
• 1 fuel line and 2 inline fuel filters
• 4 mounting clips for secure attachment

How does the kit improve starting and ignition reliability?

YOXUFA engineered the magneto with thicker copper winding for stronger electrical output and paired it with a CDI module that includes a lighted indicator to confirm spark during testing. These choices reduce misfires and help the engine turn over more predictably.

• Thick copper windings for higher output and easier starts
• Aluminum exterior on the magneto to limit surface rust
• Lighted CDI section makes bench-checks simple
• Matched components avoid compatibility mismatch problems

Will this kit fit my motorized bike’s engine?

It's designed for a broad range of small 2-stroke engines—typically used in motorized bicycles—covering 49cc through 100cc units. Still, confirm fitment by comparing physical dimensions and connector types to your existing parts before ordering.

• Works with most 49cc, 50cc, 80cc, and 100cc 2-stroke motorized engines
• Compare size and mounting points with your original coil assembly
• Check plug wire and CDI connector shapes for match
• Manufacturer note: verify pictures and measurements prior to purchase

How simple is the installation and what tools are needed?

Installation is typically a basic mechanical job for anyone comfortable with small-engine maintenance. Standard hand tools and a few minutes to route the fuel line are usually all that's required.

• Basic tools: screwdriver, pliers, socket set, and wire cleaner
• Replace magneto and CDI in the factory mounting locations
• Swap old fuel line and fit the supplied inline filters
• Use the included clips to secure wiring and fuel hose

Who is this for: This YOXUFA kit is aimed at riders, DIY mechanics and repair shops maintaining two-stroke motorized bicycles and small motorcycles in the 49–100cc range who need a single, cost-effective replacement package. It’s appropriate for troubleshooting ignition issues, replacing corroded magnetos, or refreshing aged fuel lines and filters. If you rely on your motorized bike for commuting, weekend riding or restoration projects and you can perform basic part swaps, this kit gives you the needed electrical and fuel components in one purchase.
