The Rocket is designed according to the golden ratio and conforms to the principle of human body mechanics. This bike uses an upper tube, gourd-shaped rear fork, and flat fork to give a sense of speed, strength, and power. The suspension front fork, higher handle, 26*4.0' tires, and streamlined water dropper, make it like a transformer. The suspension front fork and Shimano variable speed system make riding more comfortable, and front and rear disc brakes have a better braking effect in riding, safe and reliable. Reasonable and unique electrical system matching, plus 1:1 PAS, and step-less variable speed makes the driving force stronger, the range longer, and the battery life longer.
