Introduction

Building a hybrid bike involves integrating an electric motor with a traditional bicycle or scooter for a more sustainable and efficient ride. This article provides a detailed guide on how to construct a basic parallel hybrid scooter, combining both electric and gas power. Let's dive into the process.

Materials Required

To build a hybrid bike, you need the following components:

Electric Motor: A 500/750/1000W BLDC motor for the front wheel. Controller: To be mounted where the amber turn signals or ignition battery is located. Battery Pack: Fits underneath the footrest. Electromagnetic Clutch Mechanism: To disengage the gearbox and engine. Throttle Control: Integrated with the motor speed control. Power Switch: Allows you to choose between battery and gas power. Other accessories: Rims, wheels, and any necessary tools.

Step-by-Step Instructions

Step 1: Install the Motor

Start by mounting the electric motor on the front wheel. Ensure that the BLDC motor is securely attached, providing a smooth and reliable connection.

Step 2: Mount the Controller

Next, fit the controller where the amber turn signals or ignition battery is mounted. This is critical for regulating the power distribution between the electric and gas systems.

Step 3: Install the Battery Pack

Position the battery pack under the footrest to maximize space efficiency. Make sure the battery pack is appropriately sized for your specific requirements.

Step 4: Add the Electromagnetic Clutch Mechanism

Install an electromagnetic clutch that disengages the engine when the motor is operational. This ensures that the system can switch seamlessly between electric and gas power.

Step 5: Integrate the Throttle Control

Integrate the motor speed control mechanism with the engine throttle. This allows for easy control between the electric motor and the internal combustion engine.

Step 6: Add the Power Switch

Finally, add a power switch that lets you choose either battery or gas power. This will give you the flexibility to operate your hybrid bike in different modes.

Alternative Solutions

Some alternative solutions exist, such as using a powerful electric motor or a petrol engine. However, the most common approach is to utilize one or the other, rather than both simultaneously.

For instance, some DIY enthusiasts build a hybrid bike by using an electric wheel for the front of the motorcycle, with a generator hidden under a blanket. This setup is ideal for those with limited space or budget constraints.

Additional Tips and Considerations

Motor and Controller Selection: It is recommended to use BLDC hub motors, as they are mounted on the wheel and provide better space efficiency. For the controller, choose a high-quality product that can handle the current and voltage requirements of your motor.

Throttle Control: A key challenge in building a hybrid bike is managing the throttle control. There is no pre-existing product that can engage both the engine and motor controller simultaneously. Therefore, you will need to come up with a custom solution, such as integrating the motor speed control with the engine throttle.

Battery Selection: Battery selection is crucial. Lithium-ion batteries are the best option, as they are lightweight and have long lifespans. However, they come with a higher cost. For those on a budget, lead acid batteries are a viable alternative, though they are heavier and have a shorter lifespan.

Assembly: Assembling a hybrid bike is an art that requires both creativity and practical skills. There are no specific guidelines or rules to follow. You will need to rely on your gut feeling and logical reasoning to put everything together.
