The Hase Kettwiessel-Ride is specially designed for sporting use. Both rear wheels are driven through a differential and the front wheel is suspensiond. This makes the KettWiesel-Ride extremely stable in as well sharp turns as off-the-road use. With extra wide wheels and tires, the Kettwiesel-Ride has no problem with unpaved roads and forest paths. The Kettwiesel-Ride is the mountainbike under the tricycles!
