Key features to note include the CDI ignition system, foot pedal starting, and a complete toolkit approach that pairs engine, wiring, and drivetrain components for a unified install. Prospective buyers should review the included instructions and online installation videos for best results, especially if new to motorized bike conversions. Durability and handling are enhanced by a solid drive train setup that can support longer rides with careful maintenance.
IMAYCC Bike Motor Kit 80cc

The IMAYCC 80cc kit delivers a balance of power and manageability for riders who want quicker acceleration without excessive weight. It features a 2-stroke 80cc single-cylinder engine with a wired digital computer and CDI ignition. The engine is rated around 2.1 kW at 5000 rpm, enabling faster speeds while maintaining reliability. The kit’s components include standard drive and chain elements (44-tooth sprocket, 110-tooth chain, 36 spokes) and a straightforward starting method via foot pedal. Installation guidance is similar to other IMAYCC packages, emphasizing basic mechanical skills and a few hours of setup and tuning, aided by online tutorials.
Riders considering this option should account for heat management and long-term durability, especially during extended rides. The 80cc variant is well-suited for daily commuting and weekend rides, providing a noticeable boost without overwhelming the bicycle’s original frame. As with other kits in this category, regular maintenance and safe operation are essential to maximize the kit’s lifespan and performance.
PERFERATE 80CC 2 Stroke Engine Kit

The PERFERATE 80CC kit offers a robust 2-stroke single-cylinder engine rated up to 1.85 kW with a top speed of around 5500 rpm. CDI ignition provides reliable starting, and the kit is designed to fit most 26″ or 28″ bikes with a V-frame layout. Heat dissipation considerations are addressed via multiple cooling holes in the cylinder and head, helping to manage sustained operation. While installation instructions emphasize a 2–4 hour timeframe, users should review the provided guidance and related online resources to avoid common setup issues.
Details to evaluate include the engine’s heat management, starting ease, and the overall fit with existing bicycle components. The kit’s compatibility with 26″ and 28″ frames makes it a versatile option for riders who want a straightforward upgrade path. As with other kits, proper torque on bolts and secure mounting are critical for safe riding. Consider your local terrain and typical ride length when choosing this model.
IMAYCC 80cc Silver Bike Motor Kit

The 80cc silver IMAYCC kit mirrors the 80cc black variant in performance and assembly. It uses the same 2-stroke, air-cooled single-cylinder design with CDI ignition, a wired digital computer, and a 44-tooth drive sprocket with a 110-tooth chain. The kit is designed to fit 26–28″ bikes and is started by pedal method, offering a reliable hand-off from pedal power to motor-assisted propulsion. Installation notes highlight a typical 2–4 hour window with the same emphasis on pre-installation YouTube tutorials for smoother setup. This color variant mainly serves buyers who want a different aesthetic while maintaining the same mechanical package.
Engine performance remains suitable for commuting and longer rides, with emphasis on durability during repeated use. Prospective buyers should evaluate their frame compatibility and mounting options, ensuring that the vibration and torque from the engine do not compromise frame integrity. Regular inspections of the mounting points and proper protection of wiring are recommended for long-term reliability.
IMAYCC 100cc Bike Motor Kit (Black)

This 100cc IMAYCC kit is designed for riders seeking higher power and extended range. It features a 2-stroke, single-cylinder engine with CDI ignition and a foot pedal start. The kit specification lists 2 kW of power at 6500 rpm, delivering a faster ride and improved efficiency on longer trips. It includes the standard 44-tooth sprocket, 110-tooth chain, and 36 spokes to maintain drivetrain integrity. Installation guidance stresses basic mechanical skills and a 2–4 hour setup window, with additional help from YouTube tutorials. The 100cc model is ideal for riders prioritizing speed and range over minimal weight savings.
When evaluating a 100cc kit, consider the impact on frame stress, braking performance, and overall weight distribution. Proper mounting hardware and alignment are critical to avoid vibration and wear. Regular maintenance, including oil mix and air filter checks, will help sustain performance across varying weather and terrain conditions.
Buying Guide: Key Purchase Considerations
Engine size and riding goals: Choose 80cc for calm-to-moderate acceleration and longer rides, or 100cc for higher top speeds and more power hills. Match the kit to your bike frame and rider weight to avoid excessive stress on the frame.
Installation experience: Most kits assume basic mechanical skills. Review included instructions and search for installation videos from the brand to anticipate common challenges before starting.
Ignition system and starting method: CDI ignition and pedal start are common features. CDI offers reliable starting and smoother throttle response, while pedal start can be more convenient for on-the-go starts in low-power scenarios.
Cooling and heat management: Look for kits with effective cooling features or robust heat dissipation to prevent overheating during longer rides or steep climbs.
Drivetrain compatibility: Check sprocket sizes (typically 44 teeth) and chain tensioning requirements, plus spoke and wheel compatibility (36 spokes) to maintain wheel integrity and drivetrain performance.
Maintenance and safety: Regularly inspect mounting brackets, wiring, and exhaust routing. Ensure safe operation by following local regulations and using appropriate protective gear during riding.
These kits are designed to supplement pedaling rather than replace it entirely. They provide an extra boost for hills, longer commutes, or extended recreational riding. When selecting a model, consider your maintenance plan, local terrain, and how much you value power versus weight and ease of installation.
