Steel & Wood Solar E-Bike — A Ride Toward Less Plastic

This solar e-bike was built with a clear mission: to minimize plastic use while maintaining durability and everyday practicality. The main frame is made from steel, providing strength and stability, while solid wood elements replace plastic parts wherever possible — including the basket base, leg rests, and mounting surfaces.

The chair is modular and can be mounted either in the front or the rear, offering flexibility for solo rides or carrying passengers. Power comes from a 150W solar panel paired with an MPPT Boost controller that efficiently charges a 54.6V 12Ah lithium battery pack.

Driven by a 350W brushless hub motor, the bike achieves a top speed of 32 km/h, with an average range of 50 km per day at a cruising speed of around 25 km/h. Despite its robust build, the total weight remains under 30 kg, and it can carry up to 200 kg of load with ease.

Additional features include a motion-detecting alarm system for security, a three-point detachable solar mounting system for easy transport, and a front basket firmly attached to the frame using aluminum clamps.

Blending steel strength with wooden warmth, this project stands as a symbol of sustainable craftsmanship — proving that solar mobility can be both innovative and environmentally conscious.
