Sketch 1
Advantages
The main advantage of this tricycle is that it has been fitted with a pivot system steering. This is crucial as it increases efficiency as well as the safety of the tricycle. The tricycle has got brakes that are in a strategic position and thus can be used even in a prompt manner. There are also steering handles connected to pivot steering system to enhance safety. Finally, the chain has been connected to the back wheel to enhance easy riding.
Disadvantages
The pivot system steering risks easy breakdown of the tricycle. This is because the pivot is used by the wheels as well as the handles. The brakes also have been fitted in a manner that might confuse the rider in case of an emergency need to stop.
Sketch 2
Advantages
The tricycle has the advantage of being fitted with an adjustable frame. This will come in handy when adjusting if at all the need arises. There is also a battery/motor slot whereby a source of power can be fitted.
Disadvantages
In the case of power exhaustion, the tricycle will not be useful. There is also the possibility that battery usage will pollute the environment.
Sketch 3
Advantages
The tricycle is safe due to the fact that it has got a safety belt. This means that the rider will not fall out of the tricycle in motion in the case of an accident. Additionally, safety has been assured even at night due to the fact that it has been fitted with LED light. Another advantage is that it has Solar Panels that will generate power to drive the engine. The solar panels can also generate power to be used in other alternative chores.
Disadvantages
Failure of the engine means that the tricycle will be useless. There is also the fact that breakdown of the LED light will make riding at night impossible.
