Yes, you absolutely can build a sturdy and functional bike trailer out of wood. Combining traditional woodworking techniques with modern hardware, a wooden bike trailer offers a sustainable, customizable, and often more affordable alternative to commercially available metal options.
Why Build a Wooden Bike Trailer?
Building a wooden bike trailer isn’t just about saving money; it’s about connecting with the process of creation and crafting something tailored to your specific needs. Unlike mass-produced trailers, a DIY wooden trailer allows for complete customization of size, load capacity, and aesthetic. You can choose the type of wood, the dimensions, and even incorporate unique design elements to reflect your personal style. Furthermore, using locally sourced wood can be a more environmentally friendly option than purchasing a trailer manufactured and shipped from overseas. While metal trailers often prioritize lightweight design, a wooden trailer can prioritize strength and durability, especially if you’re planning on hauling heavy loads. This trade-off can be beneficial for those who prioritize ruggedness over speed.
Materials Matter: Choosing the Right Wood
The success of your wooden bike trailer hinges on selecting the appropriate wood. Considerations include strength, weight, resistance to rot, and cost. Here’s a breakdown of popular choices:
- Marine-grade plywood: This is an excellent option, known for its exceptional strength, water resistance, and dimensional stability. It’s more expensive than other plywood options but well worth the investment for a long-lasting trailer.
- Exterior-grade plywood: A more affordable alternative to marine-grade, exterior-grade plywood offers good weather resistance, but it’s crucial to seal it properly with a quality exterior paint or varnish.
- Hardwoods (e.g., Oak, Maple, Ash): While offering superior strength and aesthetics, hardwoods are heavier and more difficult to work with than plywood. They’re best suited for specific structural components, like the frame or axles.
- Softwoods (e.g., Pine, Fir): These are the most affordable options, but they lack the strength and durability of plywood and hardwoods. They’re generally not recommended for structural components but can be used for non-load-bearing parts.
No matter what wood you choose, ensure it’s properly dried and free from defects like knots or cracks.
Step-by-Step Guide to Building Your Trailer
Building a wooden bike trailer involves several key steps. This is a general guideline; adjust it to fit your specific design:

The axle is a critical component that supports the weight of the trailer and allows the wheels to spin freely. You can purchase a pre-made axle or fabricate one yourself using steel or aluminum tubing. Ensure the axle is perfectly straight and securely mounted to the frame. Use high-quality bearings for smooth rolling.
5. Hitch Attachment
The hitch is the connection point between the trailer and your bike. Choose a hitch system that is compatible with your bike and trailer design. There are various options available, including:
- Seatpost-mounted hitches: These attach to your bike’s seatpost.
- Axle-mounted hitches: These attach to your bike’s rear axle.
- Chainstay-mounted hitches: These attach to your bike’s chainstay.
Follow the manufacturer’s instructions carefully when installing the hitch.
6. Finishing and Protection
Once the trailer is assembled, apply a protective finish to protect the wood from the elements. Use a high-quality exterior paint, varnish, or sealant. Pay particular attention to sealing all joints and edges. Consider adding reflective tape for increased visibility, especially when riding at night.
