Understanding the Need: Why Motorize Your Wood Hauling?

Before we dive into the specifics, let’s consider why you might want to motorize your wood hauling.

Reduce Physical Strain: Hauling wood, especially uphill or over long distances, is physically demanding. A gas-powered bicycle can significantly reduce the strain on your body.
Increase Efficiency: You can haul more wood in less time, making the entire process more efficient.
Access Remote Areas: If you harvest wood from remote locations that are difficult to access with a car or truck, a motorized bicycle can be a viable solution.
Cost-Effectiveness: Compared to owning and maintaining a truck or ATV, a motorized bicycle can be a more affordable option for small-scale wood hauling.
Eco-Friendliness (Relatively): While not as green as pure pedal power, a small gas engine is still more fuel-efficient than many larger vehicles, especially for short distances.

Choosing the Right Gas Motor Kit

The heart of your wood-hauling machine is the gas motor. Selecting the right one is crucial for performance, reliability, and safety. Here’s what to consider:

Engine Size and Power

Most gas motor kits for bicycles come in sizes ranging from 49cc to 80cc.

49cc: Suitable for flat terrain and lighter loads. They are generally easier to install and maintain.
66cc/70cc: A good balance of power and fuel efficiency for moderate loads and some hills.
80cc: Best for heavier loads and steeper terrain. They offer the most power but can be less fuel-efficient and require more maintenance.

For wood hauling, I generally recommend a 66cc or 80cc engine. The extra power will be beneficial when hauling heavier loads, especially uphill. It’s better to have the power and not need it than to need it and not have it.

Two-Stroke vs. Four-Stroke

Gas motor kits come in two primary types: two-stroke and four-stroke.

Two-Stroke: These engines are simpler, lighter, and more powerful for their size. They require a mix of oil and gasoline.
Four-Stroke: These engines are more fuel-efficient, produce less noise and emissions, and do not require pre-mixing oil and gasoline.

While two-stroke engines are more common in bicycle motor kits due to their simplicity and power-to-weight ratio, a four-stroke engine can be a better choice for wood hauling if you prioritize fuel efficiency and reduced emissions. The downside is that four-stroke kits are generally more expensive and heavier.

Kit Components and Quality

A typical gas motor kit includes:

Engine
Fuel tank
Carburetor
Ignition system
Throttle cable and grip
Chain and sprocket
Mounting hardware

Pay close attention to the quality of these components. A well-made kit will last longer and require less maintenance. Look for kits with:

Durable Fuel Tank: A metal fuel tank is more durable than a plastic one.
High-Quality Carburetor: A reliable carburetor is essential for smooth engine performance.
Sturdy Mounting Hardware: The mounting hardware should be strong enough to withstand the vibrations and stresses of regular use.
Reputable Brand: Stick with reputable brands that offer good customer support and warranties.

My Recommendation:

Based on my experience, I recommend the “Flying Horse 80cc” or “Mega Motors 79cc” kits for wood hauling. These kits offer a good balance of power, reliability, and affordability. They are also widely available and have a strong community of users who can provide support and advice.

Here’s what to look for:

Frame Material and Strength

The frame is the backbone of your motorized bicycle. It needs to be strong enough to handle the added weight and stress of the engine and the wood you’ll be hauling.

Steel Frames: Steel frames are the most common and generally the strongest. They are also relatively affordable.
Aluminum Frames: Aluminum frames are lighter than steel but may not be as strong. They are more prone to cracking under heavy loads.
Chromoly Frames: Chromoly (chromium-molybdenum steel) frames offer a good balance of strength and weight. They are more expensive than regular steel frames but are a good choice if you want a lighter and more durable bicycle.

For wood hauling, I recommend a steel or chromoly frame. The added strength will give you peace of mind when hauling heavy loads.

Wheel Size and Type

The wheel size and type also play a crucial role in the performance and safety of your motorized bicycle.

26-inch Wheels: These are the most common and versatile wheel size. They offer a good balance of stability and maneuverability.
29-inch Wheels: These wheels are larger and offer better rolling efficiency, especially on rough terrain. They are a good choice if you plan to haul wood on trails or unpaved roads.
Fat Tire Bikes: These bikes have extra-wide tires that provide excellent traction and stability, especially on sand, snow, or mud. They are a good choice if you plan to haul wood in challenging conditions.

For wood hauling, I recommend 26-inch wheels with sturdy tires. If you plan to haul wood on rough terrain, consider 29-inch wheels or a fat tire bike.

Brakes

Good brakes are essential for safety, especially when hauling heavy loads.

Rim Brakes: These are the most common type of brakes on bicycles. They are relatively affordable and easy to maintain.
Disc Brakes: These brakes offer superior stopping power, especially in wet or muddy conditions. They are more expensive than rim brakes but are a worthwhile investment for safety.

I highly recommend disc brakes for a motorized bicycle used for wood hauling. The added stopping power will give you more control and confidence, especially when descending hills with a heavy load.

Suspension

Suspension can improve the ride quality and handling of your motorized bicycle, especially on rough terrain.

Front Suspension: This is the most common type of suspension on bicycles. It helps absorb bumps and vibrations, improving comfort and control.
Full Suspension: This type of suspension includes both front and rear shocks. It offers the best ride quality but is more expensive and requires more maintenance.

For wood hauling, front suspension is generally sufficient. Full suspension is only necessary if you plan to haul wood on very rough terrain.

My Recommendation:

Based on my experience, I recommend a mountain bike with a steel or chromoly frame, 26-inch wheels, and disc brakes. A bike with front suspension is also a good idea. Look for a used mountain bike in good condition to save money.

Building a Trailer for Wood Hauling

Hauling wood directly on your bicycle is not practical or safe. You’ll need a trailer to carry the wood. Here’s how to build one:

Design Considerations

Before you start building, consider the following:

Capacity: How much wood do you need to haul at a time? This will determine the size of your trailer.
Weight: How much weight can your bicycle and motor handle? The trailer should be lightweight but strong enough to carry the load.
Terrain: Where will you be hauling wood? The trailer design should be appropriate for the terrain.
Materials: What materials will you use to build the trailer? Steel is the strongest and most durable option, but it is also the heaviest. Aluminum is lighter but more expensive. Wood is a good option for the trailer bed.
Attachment Method: How will you attach the trailer to your bicycle? A hitch is the most common and secure method.

Materials and Tools

Here’s a list of materials and tools you’ll need:

Steel Tubing or Angle Iron: For the frame.
