IMAYCC 100cc Bike Motor Kit (Black)
Installation notes emphasize basic tools and about 2–4 hours for setup and tuning. The 100cc engine is a two-stroke single-cylinder with CDI ignition and air cooling. It provides about 2 kW at 6500 rpm and uses a 44-tooth drive sprocket with a 110-tooth chain and a 36-spoke wheel. The kit is designed for 26″ to 28″ bikes, with a foot-pedal starting method. Users are advised to consult installation videos and the product guide to avoid common issues.
IMAYCC 80cc Bike Motor Kit (Black)
Includes a complete 80cc two-stroke engine with a wired digital computer. The kit delivers about 2.1 kW at 5000 rpm and supports extended outdoor use with better durability. Installation is similar to other 80cc IMAYCC kits, and the package specifies a 44-tooth drive and 110-tooth chain, with 36 spokes. Aimed at enhancing speed and ride range, the kit suits most 26″ to 28″ bikes with straightforward mounting and CDI ignition.
Afranti 80cc Bicycle Engine Kit
The Afranti kit focuses on upgrading a regular bicycle into a motorized ride with a digital speedometer included. It supports most 26″ or 28″ wheeled bikes with V-frames and emphasizes upgraded hardware for improved durability. Specifications place power at 2.8 kW at 6,000 rpm, with a top speed around 50 km/h. Fuel compatibility includes #90, #92, and #95 gasoline, with a 16:1 to 20:1 oil-to-fuel ratio progression as the kit wears in. Lubrication recommendations help prolong engine life.
JAYGOVAN 110cc Bicycle Engine Kit
JAYGOVAN’s 110cc kit is a high-power option featuring a 3 kW motor at 6000 rpm and a wired digital computer for precise control. The kit emphasizes durability for use on 26″ and 28″ V-frame bikes—ideal for riders seeking stronger acceleration and longer-distance capability. Reported benefits include quiet operation and reduced vibration, enabling versatile outdoor use while maintaining simple pedal-start ignition.
IMAYCC 80cc Bicycle Engine Kit (Black) — Another Variant
This IMAYCC 80cc option emphasizes DIY-friendly installation with 2–4 hours recommended for setup. It includes a complete 80cc 2-stroke engine kit with foot-start and CDI ignition.

The guidance suggests reviewing detailed instructions and YouTube tutorials to ease installation challenges and ensure proper alignment and safety.
Buying Guide: Key Purchase Considerations
Purpose and riding style: Identify whether you want urban commuting speed, weekend trail capability, or a balance of both. Higher displacement engines (110cc) deliver more power for hills and sustained higher speeds, while 80cc units are typically lighter and easier to install for casual riding.
Compatibility and mounting: Check that the kit fits your bike’s frame and wheel size (26″–28″ and V-frame compatibility). Confirm sprocket tooth counts (commonly 44T) and chain length (110T) to ensure smooth drive train integration and chain alignment.
Durability and materials: Look for engine housings, fuel tanks, and mounting hardware that offer corrosion resistance and load-bearing capacity. Upgraded bolts and thicker mounts can reduce vibration and improve longevity during long rides.
Fuel and maintenance: Review recommended fuel types (gasoline with specific octane levels) and oil-fuel mixing ratios. A digital speedometer and CDI ignition are convenient, but plan for regular maintenance like air filter care, spark plug checks, and lubrication of moving parts.
Installation effort: Most kits require basic mechanical skills and approximately 2–4 hours. New riders should consult YouTube tutorials, installation manuals, and follow safety procedures to avoid injuries and ensure proper alignment, chain tension, and braking clearance.
Noise and vibration: Engine noise and vibration levels vary by displacement and mounting quality. If noise is a concern for your riding environment, consider kits specifically noted for quieter operation and robust mounting hardware.
Availability of support and spares: Check for included hardware lists, warranty terms, and access to replacement parts like sprockets, chains, and gaskets. A kit with reliable customer support can reduce downtime during maintenance or upgrades.
Performance and Use Scenarios
Urban commuting: An 80cc kit can offer a practical boost in speed and efficiency, especially on flatter routes, while keeping weight manageable and installation straightforward.
Hilly or longer rides: A 100cc or 110cc option provides stronger torque for climbs and extended distances, though it may require more robust mounting and a sturdier frame to handle the load.
Customization and upgradability: Some kits come with digital displays and CDI ignition, enabling easy tuning and future upgrades. If you plan future enhancements, choose a kit with widely available spare parts and a track record of reliable service.
Safety considerations: Always ensure brake performance remains sufficient after conversion, verify frame integrity, and use proper protection when testing new power outputs. Adhere to local regulations regarding motorized bicycles and licensing requirements.
These five kits provide a range of power, durability, and mounting options suitable for many riders interested in converting a standard bicycle into a motorized vehicle. Each product entry includes practical installation notes, power specs, and compatibility details to support an informed purchasing decision.
