Abstract: In the conventional tricycle, between the front frame and the bottom bracket which carries the pedal assembly, a joint is inserted that the front frame and the handlebar may tilt to the left or right. By holding the handlebar, the rider can tilt his upper body to cancel out the centrifugal force that occurs during turning and pushes him to the opposite direction of the handlebar causing a fall down accident. Between the front frame and the seat tube is installed a tiltable angle of the handlebar variable system that is remotely operated from the handlebar so that the rider can vary the tiltable angle of the handlebar for safe ride at low speeds or high speeds.
