Electric Mountainboard
Electric Mountainboard
This project involved designing and constructing an electric mountainboard using carbon fiber and kevlar. It was a continuation of a previous electric skateboard project succesfully working. This project has been documented with pictures on the ESK8 Forum for community feedback and advice (https://forum.esk8.news/t/mountainboard-carbon-fibre-diy/8534).
The board's CAD modeling focused on achieving a concave shape for flexibility without compromising ground clearance, essential for functionality at high speeds up to 60 km/h with dual electric motors. Custom trucks were designed from scratch, prioritizing stiffness and weight considerations, and utilizing Trampa's hole positions for compatibility with their decks.
Manufacturing involved creating a carbon fiber board mold from layers of MDF, CNC milled to shape, and sealed with epoxy resin. The layup included multiple layers of carbon-kevlar and carbon fiber sheets in various orientations, reinforced with a 3D core PET layer for structural integrity.
The trucks were crafted from 7075 aluminum alloy (Ergal) with steel axles, ensuring durability and performance. This project combined advanced materials and precision manufacturing to create a robust electric mountainboard tailored for high-speed and rugged terrain applications.
