Choosing the right materials: Bamboo is light, strong, and renewable, but it's not perfectly round, so it requires planning
Bamboo is an ideal material for building an electric recumbent trike. It is lightweight, strong, and renewable. Bamboo is also aesthetically pleasing, with a natural beauty that can enhance the overall design of the trike.
However, one challenge of using bamboo is that it is not perfectly round. The culms or poles taper from end to end and remain flexible even when cured. This means that building a 3-dimensional trike frame requires careful planning and some trial and error. It is important to account for the variable size and shape of the bamboo poles when designing and constructing the trike.
To address this challenge, you can use techniques such as sanding and wrapping. Sanding the bamboo poles can help create a smoother surface and more uniform shape. Wrapping the bamboo with carbon fiber tape and electrical tape can provide additional strength and stability. This process can be time-consuming, but it is important to ensure a sturdy and durable frame.
Additionally, you can use epoxy resin to fill in any uneven spots or gaps. Drilling holes in the tape before applying the resin allows excess resin to escape during compression. After the resin has dried, you can sand the joints again and apply additional layers of tape for a smooth and sturdy finish.
Overall, building an electric recumbent trike with bamboo requires careful planning and attention to detail. By taking the time to account for the unique characteristics of bamboo, you can create a strong, lightweight, and environmentally friendly trike.

Using old bike parts: You can use old bicycles, especially one with rear suspension, to save time and engineering problems
Building an electric recumbent trike using old bike parts is a great way to save money and time, especially if you use a bike with rear suspension. You can source parts from two or three old bicycles, one of which should ideally be a cheap mountain bike with rear suspension. This will simplify the engineering process and save you time and effort.
The first step is to cut off the pedals at the back of the bike, being careful not to cut too much to avoid removing the pin that locks the sprocket to the crank. You can then remove the rear wheel, gears, brake, and pedals in one piece, which is a significant time-saver. Utilise the motor mounts from an old gas-powered lawn edger as seat brackets, and you can even use the lawn edger's wheel to create a tie rod by welding in a piece of steel.
For the frame, you can weld together two 16" frames from old bikes to create the cross tube for your trike. Keep in mind that you might need to adjust the alignment if the frames are not identical in length. It is important to clamp down the parts before welding to prevent frame distortion. You can also reinforce the frame and adjust the seat position to your preference.
The steering is one of the most challenging aspects of this build. You will need to figure out how to run the cables to install an electric motor under the frame. Consider using a hub motor in the front wheel for sharper turns, although this will add weight and cost to your trike.
Finally, you can construct a dual sprocket adapter from a wheelchair hub adapter, allowing for a more comfortable pedalling speed. You can use a 24-volt wheelchair motor and gearbox with six speeds to choose from. Remember to tune the torque to your desired needs.

Electric motor installation: Install a smaller sprocket for comfortable pedalling speed, with six speeds to choose from
When installing an electric motor on your recumbent trike, it is important to consider the sprocket size for comfortable pedalling. In this case, installing a smaller sprocket going to the pedals can achieve a more comfortable pedalling speed. This is especially useful if you plan to ride your trike in hybrid mode, where you can match the top speed of the motor while pedalling.
To install the smaller sprocket, you will need to follow these steps:
- Ensure that you have the correct tools, such as a drill with steel-cutting drill bits, wrenches, screwdrivers, and a basic box of tools.
- Remove the pedals and cut them off, being careful not to cut too much to avoid damaging the pin that locks the sprocket to the crank.
- Install the smaller sprocket onto the pedals. The small sprocket will connect to the middle-sized sprocket on the pedals.
- Adjust the chain coming from the electric motor or pedals to the large sprocket on the rear wheel. Ensure that the final gearing is set to the smallest sprocket.
- Test the setup by pedalling and ensuring that the sprockets are aligned correctly.
- Fine-tune the gearing as needed. The six speeds on the rear sprocket will allow you to choose the appropriate torque for your riding conditions.
By installing a smaller sprocket, you will have a more comfortable pedalling experience, and the six speeds will provide you with flexibility during your rides. Remember to refer to the specific instructions and requirements of your electric motor and trike setup for a safe and successful installation.

Steering: Figure out how to run cables to install an electric motor under the frame
Building an electric recumbent trike from scratch can be a challenging task, and steering is one of the most difficult aspects of the project. To install an electric motor under the frame and connect it to the steering mechanism, careful planning and execution are required. Here is a step-by-step guide to help you tackle this crucial aspect of your build:
Steering and Motor Installation:
Step 1: Understanding the Steering System:
Start by understanding the steering geometry of your trike design. The steering mechanism on a recumbent trike typically involves a linkage system that connects the steering column to the front wheels. This linkage system may consist of tie rods, steering arms, and other components that transfer your steering input to the wheels. Understanding this geometry will help you identify the optimal locations for running the motor cables.
Step 2: Motor Selection and Placement:
Choose an electric motor that suits your desired performance and the physical constraints of your trike. Consider factors such as power, voltage, and physical dimensions. Plan the placement of the motor under the frame, ensuring it doesn't interfere with other components like the pedals, chainrings, or suspension. Keep in mind that the motor should be easily accessible for maintenance and adjustments.
Step 3: Cable Routing:
Determine the optimal path for running the cables from the steering mechanism to the electric motor. This may involve drilling holes in the frame to route the cables neatly and securely. Ensure that the cables have sufficient slack to accommodate the steering movement without being too loose, which could cause tangling or snagging. Use cable ties or clips to secure the cables along the frame.
Step 4: Cable Length and Tension:
Calculate the required length of the cables to ensure proper tension in the steering system. The cables should be long enough to allow for smooth steering input without being overly loose. You may need to adjust the cable length or use tension adjusters to fine-tune the steering feel. Keep in mind that the cables should be routed in a way that minimizes friction to ensure responsive steering.
Step 5: Cable Protection:
Use cable housing or conduits to protect the cables from abrasion and external elements. This is especially important if the cables are routed along areas of the frame that may be exposed to debris or moisture. Ensure that the housing is securely fastened to the frame to prevent any interference with the steering or other components.
Step 6: Testing and Adjustment:
Once the cables are installed, test the steering mechanism thoroughly. Ensure that the steering input is smooth and responsive, and make any necessary adjustments to the cable tension or routing. Fine-tune the steering to your desired feel, ensuring that the trike handles predictably and safely.
By carefully following these steps, you can successfully install an electric motor under the frame of your recumbent trike and connect it to the steering mechanism. Remember to refer to online resources, such as forums and build guides, for additional insights and inspiration. Always prioritize safety and seek assistance from experienced builders or professionals if needed.

Welding: If you can't weld, cut all parts and pay a professional welder, or use gas welding or brazing instead of electric
If you can't weld, there are a few alternatives to consider when building an electric recumbent trike. One option is to cut all the parts yourself and then pay a professional welder to assemble them for you. The cost for this service can vary, but you can expect to pay around $25-30 per hour for their labour.
Another option is to explore other types of welding, such as gas welding or brazing, which were commonly used before the advent of electric welding. Gas welding can even be used on aluminium, employing hydrogen gas instead of acetylene. In fact, early bicycles were often brazed together, avoiding the steel stress and cracking that can sometimes occur with other welding methods.
If you do decide to cut the parts yourself, you'll need a drill with steel-cutting drill bits, wrenches, screwdrivers, and other basic tools. You'll also need to carefully plan and measure where to cut, ensuring that the parts will align properly when welded together.
For example, when creating the front rack, you might use two 2ft lengths of 1x1in steel, drilling holes for bolts and assembling the pieces. For the spindles, you may be able to find a piece of steel with bearings already welded on, or you might need to weld this yourself.
Overall, while welding is a critical step in building an electric recumbent trike, there are alternatives if you can't perform this task yourself. With careful planning and the help of professionals or alternative welding methods, you can still bring your trike to life.
