Three wheeled Transforming Electric Motorbike for ultimate riding experience for both city and terrain. Inspired from Adventure riders riding in multiple road and whether conditions, the bike is designed to serve in versatile conditions and riding style by enabling transformative knee, chest, and handle grip.

Styling focused on aggressive shapes of human muscle. Not only are the forms beautiful and inspirational, but also to focus on how it flexes and transforms enabling different movement. Fluidic form and its rhythm of of focus and loose alters throughout the body and frame of the bike. 

Transforming knee and chest grip gives different riding style enabling user to ride with different position. Typically in speed mode, on road riding, riders stay low and grip tighter with knee and chest with lower position of handle grip as well. When riding light terrain, riders typically half standing up with higher handle grip to ride along with bounce and bumpiness.

Middle wheel works as extra support to better balance in rough condition and also while corner winding to support riding at full tilt.
