This is my latest delta trike. Front wheel is 24", rear wheels are 26". The frame is based on an Atomic Zombie trike with a coroplast body fastened to a tube frame. Power is routed from the pedals through a jackshaft to the left rear wheel and the right rear wheel has a Golden Motor Magic Pie direct drive hub motor. It uses a Grin Tech Cycle Analyst computer which allows the power level and speed to be set. Also it has a PAS and a throttle. I keep the power set to a max of 220 watts which allows me to cruise between 17 and 22 kph depending on the incline of the roadway. It has mesh front and rear to allow for airflow to cool both the rider and the 2 48V batteries which are located behind the seat.
