How to Start a Pocket Bike Without Pull Start?

Understanding Pocket Bike Engines

To effectively address the challenge of a non-functioning pull start, it’s essential to grasp the fundamental workings of a pocket bike engine. Most pocket bikes rely on compact two-stroke or four-stroke engines, similar to those powering lawn equipment. These engines ignite a fuel-air mixture to generate power, requiring a spark to initiate combustion. The pull start’s primary role is to rotate the engine’s flywheel, which in turn generates this crucial spark.

When the pull start fails, the challenge lies in finding alternative methods to achieve the same result: rotating the crankshaft to produce the spark. This guide will explore several viable options, each with its own set of advantages and considerations. By understanding the engine’s basic operation, you’ll be better equipped to tackle the task of starting your pocket bike without a pull start.

Method 1: Using a Drill with a Socket Adapter

One of the most popular and straightforward methods to start a pocket bike without a pull start is by using a drill with a socket adapter. This method mimics the action of a pull start by rotating the crankshaft at high speed.

Tools Needed:

• Cordless drill
• Socket adapter
• Appropriate socket size (usually 17mm or 19mm)

Step-by-Step Guide:

1. Remove the Pull Start Cover: Begin by removing the pull start cover from your pocket bike to expose the crankshaft nut.
2. Attach the Socket Adapter to the Drill: Connect the socket adapter to your drill and attach the correct size socket.
3. Position the Socket on the Crankshaft Nut: Place the socket over the crankshaft nut, ensuring a secure fit.
4. Spin the Crankshaft: Set your drill to the highest speed and spin the crankshaft by pressing the drill’s trigger. The engine should start within a few seconds.

Pros and Cons:

• Pros: Easy to perform, requires minimal tools, and is effective.
• Cons: Requires a drill with sufficient power, not ideal for portable use.

Method 2: Bump Starting the Pocket Bike

Bump starting is a technique commonly used in motorcycles and can be applied to pocket bikes as well. It involves manually rotating the rear wheel to start the engine.

Tools Needed:

• A clear, flat surface (preferably downhill)

Step-by-Step Guide:

1. Place the Bike in Neutral: Ensure your pocket bike is in neutral gear.
2. Push the Bike: Begin pushing the bike while standing beside it. If you have a helper, this can make the process easier.
3. Engage the Clutch: Once you’ve gained some speed, quickly engage the clutch while simultaneously hopping onto the bike.
4. Drop the Clutch: Release the clutch abruptly while maintaining your momentum. The engine should start as the rear wheel spins the crankshaft.

Pros and Cons:

• Pros: Requires no additional tools, effective when done correctly.
• Cons: Can be difficult to execute without assistance, not ideal for flat surfaces.

Method 3: Using a Remote Starter Box

A remote starter box is a specialized tool often used in RC (radio-controlled) cars, but it can be adapted for use with pocket bikes. This method involves placing the bike on the starter box, which spins the crankshaft.

Tools Needed:

• Remote starter box

Step-by-Step Guide:

1. Position the Bike on the Starter Box: Place your pocket bike on top of the starter box, ensuring the rear wheel aligns with the starter’s spinning wheel.
2. Engage the Starter: Activate the starter box, which will spin the rear wheel and, in turn, the crankshaft.
3. Start the Engine: Once the engine catches, remove the bike from the starter box.

Pros and Cons:

• Pros: Reliable and efficient, especially for frequent use.
• Cons: Requires purchasing or borrowing a starter box, which can be costly.

Method 4: Using a Rope Technique

If you’re in a pinch and don’t have access to power tools, you can use a simple rope to start your pocket bike. This method is a bit more labor-intensive but can be effective.

Tools Needed:

• Sturdy rope

Step-by-Step Guide:

1. Wrap the Rope Around the Crankshaft Nut: After removing the pull start cover, wrap a sturdy rope around the crankshaft nut. Ensure the rope is wound tightly and leaves enough length to pull.
2. Pull the Rope: Hold onto the bike firmly, and pull the rope sharply to rotate the crankshaft. You may need to repeat this several times before the engine starts.

Pros and Cons:

• Pros: Simple and requires no special tools, useful in emergencies.
• Cons: Can be tiring and requires precise technique, not as reliable as other methods.

Method 5: Installing an Electric Start Kit

For those who want a permanent solution, installing an electric start kit on your pocket bike is an excellent option. This method requires some mechanical knowledge but eliminates the need for a pull start altogether.

Tools Needed:

• Electric start kit (compatible with your pocket bike model)
• Basic hand tools

Installation Steps:

1. Purchase the Right Kit: Ensure the electric start kit is specifically designed for your pocket bike model. Compatibility is crucial for a smooth installation.
2. Remove the Pull Start: Carefully disassemble the pull start assembly to create space for the electric start components. Refer to your pocket bike’s manual for specific instructions.
3. Install the Electric Start Motor: Mount the electric start motor in the designated location on the engine. Secure it tightly using the provided hardware.
4. Connect the Wiring: Connect the electric start motor’s wiring to the bike’s electrical system. Follow the kit’s instructions carefully to avoid electrical issues.
5. Install the Battery: If not included in the kit, securely mount the battery in a suitable location on the bike. Connect the battery to the electric start system.
6. Test the System: Once everything is connected, turn on the ignition and press the start button. Your pocket bike should start effortlessly.

Pros and Cons:

• Pros: Permanent solution, convenient, and easy to use.
• Cons: Requires mechanical skills, initial installation can be time-consuming.

Preventative Maintenance Tips

Proactive care for your pocket bike can significantly extend the life of your pull start and prevent unexpected breakdowns. By incorporating these maintenance practices into your routine, you’ll ensure your bike is always ready for action.

Regular Inspections:

• Pull Start Cord: Periodically inspect the pull start cord for signs of wear, fraying, or damage. Replace it immediately if any issues are found. A worn cord can snap during use, leaving you stranded.
• Moving Parts: Lubricate the pull start mechanism with a suitable lubricant to reduce friction and wear. Proper lubrication ensures smooth operation and prevents premature failure.
• Engine Cleanliness: Regularly clean your pocket bike’s engine to remove dirt, debris, and other contaminants. Buildup can hinder the pull start’s performance and lead to excessive strain.

Storage and Handling:

• Proper Storage: When storing your pocket bike, choose a dry, sheltered location to protect it from the elements. Moisture can accelerate corrosion and damage sensitive components, including the pull start.
• Gentle Handling: Avoid jerking or applying excessive force to the pull start cord. Rough handling can weaken the cord and internal components.

By following these preventative maintenance tips, you’ll not only extend the life of your pull start but also improve your overall riding experience. A well-maintained pocket bike is less likely to break down, ensuring you can enjoy countless hours of fun and excitement.
