This is a tricycle. The front wheel is larger than the rear wheel. There is a seat on the frame which goes from the rear wheel to above the front wheel. There are forks that go from the front wheel up through the frame to the handlebars.
This Tricycle icon is made in Material Design style
developed by Google. This style is based on extremely simplified shapes, thin two-pixel lines, and is optimized for 24x24 px. Unlike other vector icon packs that have merely hundreds of icons, this icon pack contains 5,700 icons, all in the same style and quality.
