Fundamentals of Bike Frame Design
Building a wooden bike frame requires a good understanding of the fundamentals of bike frame design. Here are some key considerations to keep in mind:
The material you choose for your bike frame will determine the strength, weight, and durability of your bike. Wooden bike frames are a popular choice due to their unique aesthetic appeal, but they can be heavier and less durable than metal frames. When selecting wood for your frame, look for hardwoods that are strong and durable, such as oak, ash, or walnut.
The geometry of your bike frame will determine how it handles and feels while riding. The key measurements to consider are the length of the top tube, the head tube angle, and the seat tube angle. A longer top tube will result in a more stretched-out riding position, while a shorter top tube will result in a more upright position. A steeper head tube angle will result in quicker, more responsive handling, while a shallower angle will result in more stable, predictable handling.
The joints of your bike frame will determine how strong and secure the frame is. There are several different types of joints used in bike frame construction, including lugs, fillet brazing, and TIG welding. Lugs are the most traditional and offer a classic look, while fillet brazing and TIG welding offer a more modern, seamless appearance.
The components you choose for your bike frame will determine how it performs and feels while riding. Key components to consider include the wheels, brakes, drivetrain, and handlebars. When selecting components, be sure to choose ones that are compatible with your frame and that meet your specific riding needs.
By keeping these fundamentals in mind, you can design and build a wooden bike frame that is strong, durable, and performs well on the road.

Preparing the Wood
Before you start building your wooden bike frame, you need to prepare the wood. This involves choosing the right type of wood, cutting it to the right size, and sanding it to create a smooth surface.
Choosing the Wood
Choosing the right type of wood is important when building a wooden bike frame. You want a wood that is strong, lightweight, and durable. Some of the best woods for building bike frames include ash, oak, and maple. These woods are strong and lightweight, making them ideal for bike frames.
Cutting the Wood
Once you have chosen the right type of wood, you need to cut it to the right size. You will need to measure and mark the wood before cutting it to ensure that you get the right size pieces. You can use a saw to cut the wood, but make sure that you use a saw with a fine blade to ensure a clean cut.
Sanding the Wood
After you have cut the wood to the right size, you need to sand it to create a smooth surface. Sanding the wood will remove any rough edges or splinters, making it easier to work with. You can use sandpaper to sand the wood, starting with a coarse grit and working your way up to a finer grit. Make sure that you sand the wood evenly to create a smooth surface.
In summary, preparing the wood is an important step when building a wooden bike frame. You need to choose the right type of wood, cut it to the right size, and sand it to create a smooth surface. With these steps, you can ensure that your wooden bike frame is strong, lightweight, and durable.
Assembling the Frame
Once you have all the pieces of your wooden bike frame cut and shaped, it’s time to assemble them. This section will guide you through the process of joining the pieces and securing the joints.
Joining the Pieces
To join the pieces of the frame, you can use a variety of techniques such as mortise and tenon joints, lap joints, or dowel joints. Mortise and tenon joints are a popular choice for wooden bike frames because they provide a strong and durable connection.
To create a mortise and tenon joint, you will need to cut a rectangular slot (mortise) into one piece of wood and a matching projection (tenon) on the other piece of wood. The tenon is then inserted into the mortise and secured with glue.
Lap joints are another option for joining the pieces of your frame. In a lap joint, one piece of wood overlaps the other and is secured with glue and screws or nails. This type of joint is easier to make than a mortise and tenon joint, but it may not be as strong.
Dowel joints are another popular option for wooden bike frames. In this type of joint, a hole is drilled into both pieces of wood and a dowel is inserted to connect them. This type of joint is strong and easy to make, but it requires precision drilling.
Securing the Joints
Once you have joined the pieces of your frame, you will need to secure the joints. The most common way to do this is with glue and clamps. Apply a thin layer of glue to both surfaces of the joint and clamp the pieces together until the glue dries.
In addition to glue, you can also reinforce the joints with screws or nails. However, be careful not to use too many screws or nails as this can weaken the wood and make it more prone to splitting.
After the glue has dried and the joints are secured, you can sand the frame to smooth out any rough edges or imperfections. Finally, you can add any additional components such as the bottom bracket, seat post, and handlebars to complete your wooden bike frame.
