CUBELLIN 100cc Bike Motor Kit
The CUBELLIN 100cc Bike Motor Kit is a robust 4-stroke system designed for durable performance on bicycles. Its 3.5 HP output and 3600 RPM max speed aim to deliver strong acceleration up to 50 km/h. The kit emphasizes fuel efficiency with a 0.52-gallon tank and a reported fuel consumption around 0.66 gallons per 100 km, aided by an overhead valve design. Construction uses an aluminum engine shell and a painted iron fuel tank, complemented by a rust-resistant chain and nylon side cover to extend service life. Suitable for riders seeking a solid, mid-displacement conversion with steady performance.
Key features include a compact footprint (11.81 x 5.51 x 5.9 inches), durable materials, and a high load capacity. The kit’s 440-pound max bearing capacity supports varied rider weights and accessories. Installation will require mechanical confidence and adherence to safety guidelines for mounting and chain alignment. Fuel management and regular maintenance are recommended to maintain efficiency and longevity.
YaggeBike 80cc Gas Engine Kit
The YaggeBike 80cc 2-stroke engine kit provides a balance of power and simplicity for upgrading a mountain, road, or cruiser bicycle. This kit includes essential components for a complete DIY conversion, such as a carburetor, ignition coil, fuel tank, muffler, and chain. Built for heat dissipation and long-term durability, the kit aims to deliver strong acceleration and reliable operation while maintaining a manageable weight. A 2-stroke design typically offers simpler maintenance and lighter components, with the trade-off of potentially higher fuel consumption and more frequent maintenance than a 4-stroke system.
Users should anticipate a straightforward installation path but may need mechanical know-how for proper alignment and throttle linkage. Compatibility with 26″ to 28″ wheels makes it a versatile option for riders seeking a relatively quick upgrade. Safety considerations include securing the engine, ensuring frame compatibility, and wearing protective gear during testing and riding.

Buying Guide: Key Purchase Considerations
- Engine type: 4-stroke vs. 2-stroke. 4-stroke engines typically offer smoother operation, better fuel efficiency, and longer life, while 2-stroke engines often provide quicker power delivery and lighter weight but may require more frequent maintenance.
- Displacement and power: Higher displacement (e.g., 100cc) generally yields more torque and top speed, but also increases weight and fuel consumption. Match to your riding style and local regulations.
- Fuel capacity and range: Tanks around 0.5 gallons are common; consider your typical ride distance and availability of fuel stations.
- Drive system: Chain drive vs. belt drive. Chains are robust and easier to repair, while belts can offer quieter, lower-maintenance operation but may be less forgiving on misalignment.
- Durability and materials: Aluminum housings, steel chains, and rust-resistant coatings extend life in varied weather conditions.
- Installation complexity: Some kits require significant fabrication, wiring, or frame modifications. Assess your mechanical skill level and whether professional installation is advisable.
- Safety and legality: Motorized bicycles may be subject to local regulations regarding speed, power, and operator licensing. Ensure compliance before riding on public roads.
- Maintenance needs: Regular inspection of the carburetor, ignition system, fuel lines, and exhaust is essential for consistent performance and safety.
- Compatibility: Verify fit for your bike’s wheel size (commonly 26″–28″), frame clearance, and available mounting points before purchasing.
