A pedal-propelled tricycle includes two front wheels, a rear wheel, a pedal drive and a handle bar. The pedal drive serves to rotate the axle of one front wheel by way of a chain while a brake on the axle of the other front wheel is adapted to be operated from an actuator on the handle bar. The handle bar serves to steer the rear wheel and carries a second actuator for operating a brake on the rear wheel.
