Supplier's note

  1. Three Technical Breakthroughs:

    • Modular Design: With adjustable mounting points, users can easily swap components for tailored performance (e.g., upgrading from 50cc to 150cc).
    • Aluminum Construction: 20% lighter than cast iron engines, reducing unsprung weight for better handling.
    • Air-Cooled Reliability: Requires no coolant maintenance, ideal for harsh environments like dusty trails or tropical climates.

  2. Optimal Version Selection:

    • Base Model (50cc): Perfect for casual riders needing budget-friendly, low-maintenance power for short commutes or vintage-style bikes.
    • Advanced Model (90cc): Balances power and affordability for urban commuters or light off-road use, with enough torque for hilly terrain.
    • Pro Model (150cc): The chemical-resistant aluminum frame and tripled power output (vs. industry 50cc baselines) make it ideal for professional delivery riders or performance enthusiasts. With its modular design, it can be paired with aftermarket exhaust systems to enhance throttle response.

Example benefit: "With the Pro Model’s 150cc displacement, you can achieve 9 HP—20% more than competing 125cc engines—while maintaining the simplicity of air-cooled reliability."
