? Trike upright trikes for adults have front and rear brakes. The front brakes are usually "pull brakes" or V-brakes, and the rear brakes can be pull brakes or internal drum brakes. Let's us see some early pedal of the trike.

? Some early pedal trike from the late 1800s used two wheels in tandem on one side and a larger driving wheel on the other. Another design is an in line three wheeled vehicle, with two steered wheels: one at the front and the other in the middle or at the rear. It is not unusual for tricycles to have front and rear wheels of different sizes.
