2-Stroke Motorised Bicycle (3 Timber Tools Hacks)

It was a sweltering summer afternoon back in ’98. I was knee-deep in sawdust, wrestling with a particularly stubborn oak log, when my neighbor, old man Fitzwilliam, chugged up on something that looked like it had been cobbled together from spare parts and a fever dream. It was a bicycle, alright, but with a snarling two-stroke engine strapped to the frame. He grinned, a mischievous glint in his eye, and hollered, “This here’s my timber transport! Gets me to the back forty faster than any mule!” That contraption, a 2-stroke motorized bicycle, became the inspiration for countless hours of tinkering and experimenting. Little did I know, it would also lead me to discover some ingenious timber tools hacks that would save me time, energy, and a whole lot of backache. Let’s dive into how you can adapt this concept for your own wood processing adventures.

2-Stroke Motorised Bicycle: 3 Timber Tools Hacks

The idea of combining a motorized bicycle with timber tools might seem a bit outlandish at first, but trust me, it’s all about efficiency and resourcefulness. I’ve found that integrating the mobility of a 2-stroke bicycle with the functionality of basic timber tools can create a surprisingly versatile and practical system for small-scale wood processing. These hacks are perfect for anyone who needs to move tools and materials around a property, access remote areas, or simply wants to add a bit of ingenuity to their wood processing routine.

Hack #1: Chainsaw Carrier and Fuel Transport

One of the biggest challenges I faced when working in remote sections of my property was lugging my chainsaw, fuel, oil, and other necessary equipment. It was exhausting and inefficient. The solution? A custom-built chainsaw carrier mounted on the back of my motorized bicycle.

Designing the Carrier

The key to a good chainsaw carrier is stability and security. I designed mine using heavy-duty steel tubing and a sturdy plywood base. The frame is welded to the bicycle’s rear rack, providing a solid foundation.

Materials:
- 1-inch steel tubing (approximately 6 feet)
- ½-inch plywood (approximately 2 feet x 2 feet)
- Welding equipment
- Metal cutting tools (angle grinder, hacksaw)
- Bolts and nuts (various sizes)
- Rubber padding
- Metal straps with buckles
Construction:
1. Frame Fabrication: I started by cutting the steel tubing to the desired lengths. This involved creating a rectangular frame that would sit securely on the rear rack of the bicycle.
2. Welding: The tubing was then welded together to form a strong, rigid frame. Welding is crucial for ensuring the carrier can withstand the weight and vibrations of the chainsaw.
3. Plywood Base: A piece of plywood was cut to fit inside the steel frame and bolted securely in place. This provides a stable platform for the chainsaw and other equipment.
4. Chainsaw Mount: I fashioned a custom chainsaw mount using additional steel tubing and rubber padding. The mount is designed to hold the chainsaw securely in place, preventing it from bouncing around during transport. Metal straps with buckles were added to further secure the chainsaw.
5. Fuel and Oil Holders: To carry fuel and oil, I incorporated holders made from repurposed PVC pipe. These holders are mounted to the side of the carrier frame and are designed to hold standard fuel and oil containers securely.
6. Finishing Touches: Finally, I added rubber padding to any areas where the chainsaw might come into contact with the metal frame. This helps to prevent scratches and damage to the chainsaw.
Measurements:
- Carrier Frame: 24 inches long x 18 inches wide x 12 inches high
- Chainsaw Mount: Designed to fit a chainsaw with a 20-inch bar
- Fuel Holders: 4-inch diameter PVC pipe, 10 inches long

Benefits

Increased Efficiency: I can now transport my chainsaw and fuel in a single trip, saving valuable time and energy.
Reduced Strain: No more lugging heavy equipment over rough terrain.
Improved Safety: The chainsaw is securely mounted, reducing the risk of accidents.

Challenges and Solutions

Weight Distribution: It’s crucial to distribute the weight evenly to maintain balance while riding. I found that positioning the fuel and oil containers low and towards the center of the carrier helped to improve stability.
Vibration: The vibration from the engine can loosen bolts and cause the carrier to rattle. I used lock washers and threadlocker to prevent this.
Durability: The carrier needs to be able to withstand the rigors of off-road use. I used heavy-duty materials and reinforced all critical joints to ensure durability.

Example

One afternoon, I needed to fell a tree deep in the woods behind my property. Normally, this would have involved multiple trips back and forth to carry my chainsaw, fuel, and other equipment. With my motorized bicycle and chainsaw carrier, I was able to get the job done in a single trip, saving me at least an hour of time and a lot of unnecessary effort.

Takeaway: A well-designed chainsaw carrier can significantly improve the efficiency and safety of your wood processing operations.
