On Designboom: a tilt-action cargo trike from Butchers & Bicycles
Unlike with bikes, where one naturally leans into a turn, tricycles are difficult to turn at anything but low speeds.
On the MK1 it is possible to lean into the turn in the same intuitive way as a regular bicycle, without compromising safety. The environmentally efficient way of traveling also provides the same lightness and stability from regular designs, making it easy to cruise along even at high speeds.
