Donut: The Innovative Folding Bicycle

Aesthetically Pleasing and Convenient

Donut is a revolutionary folding bicycle that combines functionality with a unique circular design. Inspired by the need to address traffic congestion and pollution, as well as the existing folding bicycle designs, Donut offers a fresh take on urban commuting.

What sets Donut apart from other folding bicycles is its easy folding mechanism and its aesthetically pleasing circular frame. When folded, the bike forms a perfect circle with no parts protruding outside the frame. This innovative design allows for easy carrying, storage, and stowing, making it ideal for urban dwellers with limited space.

The circular frame of Donut is made of lightweight aluminum alloy, ensuring durability while keeping the weight of the bike manageable. The front and rear forks are pivoted to the circular frame, providing stability and a smooth riding experience. The bike features a tubular pedal that slides and rotates inside the crank bar, allowing for efficient pedaling. The combination of chain and gear drives transfers motion to the rear wheel, ensuring a comfortable and effortless ride.

Donut also offers additional features for the rider's convenience. It has a height-adjustable seat and handlebars, allowing for a customizable riding experience. The bike is equipped with GPS and a cyclometer, providing navigation and tracking capabilities. With Donut, commuting becomes not only efficient but also enjoyable.

The Donut folding bicycle is a result of the creative and technical challenges overcome by Arvind Mahabaleshwara. The mechanism to fold the bicycle components into a circular shape with a drive mechanism required innovative thinking and engineering expertise.

Designed and realized in Bangalore, India, the Donut folding bicycle has gained recognition for its unique design. It was awarded the Bronze A' Design Award in the Vehicle, Mobility, and Transportation Design category in 2013. This prestigious award acknowledges the outstanding and creatively ingenious design of Donut, which incorporates best practices in art, science, design, and technology. The Donut folding bicycle contributes to improving the quality of life by offering a sustainable and convenient mode of transportation.
