Abstract
A vehicle comprises at least two wheels, a front wheel and a rear wheel. A driving motor is connected as a unit to a framework, the framework being made up of a number of tubular members forming two trapezium structures. The wheels are connected to the motor-framework unit by further members, as well as dampening devices. A transmission between the driving motor and both of the front and rear wheels is also provided. A steering assembly is connected to the front steering wheel and the framework. A strut, which may be part of the transmission, is adjustably connected between the motor-framework unit and the steering assembly. Furthermore, the vehicle can adjust the castor angle of the front wheel.
