Qooder
The Qooder is a model of street-legal motorized quadricycles and is the flagship of Qooder SA. It is a four-wheeled scooter and has double rear-wheel drive with mechanical differential and 4-wheel integral braking. It has a hydro-pneumatic suspension, known as "Hydraulic Tilting System," or "HTS," which allows a rider to tilt all of the wheels simultaneously for motorcycle-like riding dynamics. In 2020 it incorporated an electronic version of the HTS, known as E-HTS, which locks the tilting while the vehicle is stopped or parked to allow riders to keep their feet up while stopped. The Qooder is gasoline operated and also available in an electric version which utilizes the Zero Motorcycles electric drive system. The Qooder is a street-legal vehicle that also has an off-road enduro version called the XQooder.
