There are 9 different types of trikes. The problem is, there has not been an unanimous agreement about what we should call them. I suggest we all agree on the following types. Reverse Trike, Delta Trike, Reverse Motortrike, Delta Motortrike, Reverse Pedaltrike, Delta Pedaltrike, Pedal Drift Trike, Motorized Drift Trike and Child's Tricycle. If everyone calls them the same thing, then when people search for what they want, they will be able to find it!
