Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Engine Power Range: Equipped with 48cc to 80cc 4-stroke petrol engines, offering versatile power outputs for different terrain and user needs.
  • Mountain Bike Conversion: Designed to retrofit standard mountain bikes into motorized vehicles, enabling enhanced speed, endurance, and off-road capability.

Key features

  • 1. Lightweight Aluminum Engine Block (Material Technology)

    • With an aluminum engine block, reduce weight for better agility and fuel efficiency. The corrosion-resistant aluminum construction is up to 20% lighter than traditional cast-iron engines*, enabling smoother handling and extended riding range on mountain terrains.

  • 2. Modular Customization Design (Interactive Design)

    • With modular components, customize your engine setup to match your riding style. The kit includes interchangeable bolts, nuts, and washers, offering 30% more customization flexibility than standard bicycle engine kits*. Ideal for fine-tuning performance for off-road or urban use.

  • 3. High-Performance 4-Stroke Engine (Performance Parameters)

    • With a 4-stroke engine design, achieve higher power output and lower emissions compared to 2-stroke models*. The 48–80cc engine range delivers up to 15% more power and 25% fewer emissions*, ensuring reliable performance for mountain biking.

  • 4. Rugged Cooling System (Scenario Solutions)

    • With heat-dissipating cooling fins, maintain optimal engine temperature during prolonged off-road use. The engine block’s finned design ensures 40% better heat dispersion than non-finned models*, preventing overheating on steep or rugged terrains.

  • 5. Premium Material Certifications (Certification Standards)

    • With BEST TOUCH’s quality assurance, enjoy durable, eco-conscious components. The stainless steel exhaust and aluminum parts meet ISO 9001 manufacturing standards*, ensuring longevity and compliance with environmental regulations.
