Is it Worthful to buy Hybrid CNG Bikes over Electric Bike and converting to CNG

  • When comparing CNG bikes to electric scooters, each has its advantages and drawbacks. Here are the key benefits of CNG bikes over electric scooters:

Benefits of CNG or Petrol Bikes

  1. Longer Range:
    • Petrol to CNG  bikes typically have a longer range per fill-up compared to the range of electric scooters on a single charge.
    • This makes CNG bikes more suitable for long-distance travel.
  2. Refueling Time:
    • Refueling a CNG or pterol bike takes only a few minutes, similar to refueling a petrol bike.
    • In contrast, charging an electric scooter can take several hours unless using a fast charger.
  3. Wider Availability of Fuel Stations:
    • In many regions, CNG or petro; refueling stations are more prevalent and established compared to electric vehicle (EV) charging infrastructure. This can make it more convenient to refuel a CNG bike.
  4. Performance Consistency:
    • CNG bikes generally offer consistent performance without significant power drop, even when the fuel level is low. Electric scooters can experience reduced performance as battery charge decreases.
  5. Lower Initial Cost:
    • CNG bikes often have a lower initial purchase cost compared to electric scooters, making them more affordable for some consumers.
  6. Less Dependence on Electricity:
    • CNG bikes do not rely on electricity, making them a good option in areas with unreliable power supply or where electricity is expensive.
  7. Proven Technology:
    • CNG technology is well-established and has been used for years in various types of vehicles, providing a sense of reliability and familiarity to consumers.

Range of CNG Bikes

  • The mileage of CNG bikes can vary depending on the specific model and usage conditions.
  • Generally, CNG (Compressed Natural Gas) bikes offer a significant advantage in terms of fuel efficiency compared to traditional petrol bikes.
  • Here are some typical figures for CNG bike mileage:
    • Average Mileage:
      • CNG bikes usually provide a mileage of around 100-350 kilometers per kilogram of CNG.
      • This is higher than the mileage offered by most petrol bikes.
    • Fuel Cost Efficiency:
      • Since CNG is cheaper than petrol, the cost per kilometer for running a CNG bike is lower.
      • This makes CNG bikes more economical for daily commuting.
    • Environmental Impact: CNG bikes produce lower emissions compared to petrol bikes, making them a more environmentally friendly option.
  • Specific models and brands may have different mileage figures, and the actual mileage can also depend on factors such as riding habits, maintenance, and road conditions.

How to Convert Petrol Bikes to CNG Bikes

  • Converting petrol bikes to CNG involves installing a CNG conversion kit. Here’s a step-by-step guide to converting a petrol bike to a CNG bike:

Steps to Convert Petrol Bikes to CNG Bikes

  1. Select a Certified CNG Kit:
    • Choose a certified CNG conversion kit compatible with your bike model. Ensure the kit is approved by the relevant regulatory authority in your country.
  2. Find a Qualified Mechanic or Service Center:
    • It’s crucial to have the conversion done by a professional who has experience with CNG conversions. This ensures safety and proper installation.
  3. Components of a CNG Conversion Kit:
    • CNG Cylinder: Stores the compressed natural gas.
    • Reducer/Regulator: Converts high-pressure CNG to low-pressure suitable for the engine.
    • Injector: Delivers the CNG to the engine.
    • Electronic Control Unit (ECU): Manages the fuel delivery system.
    • Mixer: Mixes CNG with air before entering the combustion chamber.
    • Valves and Pipes: Connect and control the flow of CNG.
  4. Installation Process:
    • Mounting the CNG Cylinder: Securely attach the CNG cylinder to the bike, usually on the rear or under the seat.
    • Connecting the Reducer/Regulator: Install the reducer/regulator to manage gas pressure.
    • Installing the Injector and Mixer: Integrate the injector and mixer into the engine’s fuel system.
    • Wiring the ECU: Connect the ECU to the bike’s electrical system to manage fuel injection.
    • Setting Up Valves and Pipes: Install the necessary valves and pipes to ensure proper gas flow.
  5. Safety Checks and Calibration:
    • After installation, perform thorough safety checks to ensure there are no leaks.
    • Calibrate the ECU to optimize performance and fuel efficiency.
    • Check the entire system for proper functioning.
  6. Testing and Tuning:
    • Start the bike and check for any abnormalities.
    • Test ride the bike to ensure smooth operation on CNG.
    • Fine-tune the system if necessary.
  7. Compliance and Certification:
    • Ensure the conversion meets all regulatory requirements.
    • Obtain necessary certifications and approvals from relevant authorities.

  • Warranty: Converting your bike to CNG might void the manufacturer’s warranty. Check with your bike manufacturer before proceeding.
  • Fuel Availability: Ensure CNG refueling stations are accessible in your area.
  • Performance: Be aware that CNG bikes might have slightly different performance characteristics compared to petrol bikes.


  • Regularly inspect the CNG system for leaks or wear.
  • Follow a maintenance schedule for the CNG components.
  • Ensure the bike is serviced by professionals experienced with CNG systems.

Considerations for Electric Scooters

  • Environmental Impact: Electric scooters produce zero tailpipe emissions, which is beneficial for urban air quality and overall environmental impact.
  • Operating Costs: Electric scooters have lower operating costs, as electricity is often cheaper than CNG, and they have fewer moving parts, reducing maintenance needs.
  • Noise Pollution: Electric scooters are much quieter than CNG bikes, contributing to reduced noise pollution in urban areas.
  • Government Incentives: Many governments offer incentives and subsidies for purchasing electric vehicles, which can offset the higher initial cost.


  • The choice between a CNG bike and an electric scooter depends on individual needs and circumstances.
  • CNG bikes offer advantages in terms of range, refueling time, and performance consistency, making them suitable for longer commutes and areas with better CNG infrastructure.
  • On the other hand, electric scooters are more environmentally friendly, have lower running costs, and benefit from government incentives, making them ideal for short urban commutes.
