Building your own electric skateboard is a rewarding project that combines mechanical engineering, electronics, and woodworking. By assembling a custom board, you gain full control over the speed, range, and aesthetics of your ride. Whether you want a high-speed commuter or a portable cruiser, the DIY approach allows you to tailor every component to your specific needs. This guide provides a straightforward path from selecting parts to your first test ride.
Understanding the Core Components
Before you begin assembly, you must understand the individual parts that make an electric skateboard function. Each component plays a vital role in the board’s performance and reliability.
The Deck
The deck is the foundation of your board. For beginners, a longboard deck is usually recommended because it provides more stability at high speeds and offers plenty of space underneath for the battery and electronics. A stiff deck is easier to mount components to, while a flexible deck offers a smoother ride but requires a split enclosure to allow for bending.
The Motor
Electric skateboard motors are typically brushless DC (BLDC) motors. They are categorized by their “KV” rating, which indicates how many revolutions per minute the motor turns per volt. For a standard build, a motor with a KV between 170 and 230 is ideal. Larger motors, often labeled as 6354 or 6374, provide more torque for climbing hills and faster acceleration.
The Electronic Speed Controller (ESC)
The ESC is the brain of your skateboard. It regulates the power sent from the battery to the motor based on your remote input. Many DIY builders use a VESC (Vedder Electronic Speed Controller), which is an open-source hardware option that allows for deep customization via software.
The Battery Pack
The battery is the most expensive and critical part of the build. Most builders use Lithium-Ion (Li-ion) or Lithium-Polymer (LiPo) batteries. Batteries are rated by their “S” number (cells in series) and “P” number (cells in parallel). A common setup is a 10S2P or 12S3P configuration, providing a balance of voltage for speed and capacity for range.
Choosing Between DIY Kits and Individual Parts
When starting your build, you have two main paths: buying a complete DIY kit or sourcing individual parts. Both methods have distinct advantages depending on your experience level.
- DIY Kits: These kits include most of the necessary components like the motor, trucks, and drivetrain. Kits ensure that the parts are compatible with each other, which reduces the risk of mechanical failure and saves time during assembly.
- Individual Parts: Sourcing parts separately allows for maximum customization. You can choose a specific deck, high-end wheels, and a custom-built battery. This is often more expensive and requires more research to ensure compatibility.
Essential Tools for the Build
To complete your project safely and effectively, you will need a few basic tools. Having these ready before you start will prevent delays.
- Soldering Iron: Used for connecting wires and attaching connectors to the ESC and battery.
- Hex Key Set and Wrenches: Necessary for mounting the trucks, motors, and enclosures.
- Power Drill: Required for creating holes in the deck to mount the electronic enclosures.
- Heat Shrink Tubing: Essential for insulating wire connections to prevent short circuits.
- Multimeter: Useful for checking battery voltage and ensuring your electrical connections are solid.
Step-by-Step Assembly Guide
Once you have gathered your components and tools, you can begin the assembly process. Follow these steps to ensure a clean and functional build.
1. Prepare the Deck and Trucks
Start by mounting your trucks to the deck just as you would on a standard skateboard. If you are using a motor mount, attach it to the rear truck before securing the truck to the board. Ensure the mount is aligned perfectly straight so the belt will run smoothly between the motor and the wheel.
2. Install the Drivetrain
Attach the motor to the motor mount using the provided screws. Next, install the small pulley on the motor shaft and the large pulley on one of your rear wheels. Slide the drive belt over both pulleys. Adjust the motor position until the belt is tensioned correctly; it should be tight enough not to slip but loose enough to rotate freely without excessive friction.
3. Configure the Electronics
Connect your motor wires to the ESC. If you are using a VESC, you will need to connect it to a computer and use configuration software to set your current limits, voltage cutoffs, and remote settings. This step is crucial for protecting your battery and ensuring the motor spins in the correct direction.
4. Mount the Enclosure
Place your battery and ESC inside their protective enclosures. Hold the enclosures against the bottom of the deck to find the best placement. Mark the holes, drill through the deck, and use bolts to secure the enclosures. Many builders use foam padding inside the enclosure to prevent the battery from vibrating against the deck.
Safety and Maintenance
Operating a DIY electric skateboard requires a commitment to safety. Always wear a helmet and appropriate protective gear. Before every ride, perform a quick inspection of your board.
Check that all bolts are tight, especially those on the motor mount and trucks. Inspect the drive belt for any tears or debris. Because DIY boards are subject to significant vibration, using a thread-locking fluid on your screws can prevent them from vibrating loose over time.
Battery maintenance is also vital. Never leave your battery charging unattended, and store it in a cool, dry place. If you notice any swelling or damage to the battery casing, stop using it immediately and seek a professional replacement.
Final Testing
Before you step on the board, perform a bench test. Turn on the remote and the board, then slowly apply the throttle while the wheels are off the ground. Ensure the motor sounds smooth and the brakes engage correctly. Once you are confident in the mechanical and electrical setup, find a flat, open area for your first low-speed test ride.
Building a custom electric skateboard is a journey of learning. As you get more comfortable with your build, you can experiment with different gear ratios or battery configurations to further enhance your riding experience.
