Chassis System

Integrated Electric Chassis Systems for Short-Distance EV OEMs

CYBEST engineers and manufactures high-strength chassis platforms for electric three-wheelers, cargo trikes, and short-distance utility vehicles. We do not supply bare, isolated steel frames—we deliver fully coordinated powertrain and chassis integration (Axle + Motor + Controller + Battery) to help vehicle manufacturers reduce development costs and accelerate time-to-market.

With an R&D operation center in Changzhou and manufacturing bases in Shangqiu, Henan and Feng County, Xuzhou, combines product development with in-house manufacturing. The production system follows ISO 9001 quality management requirements and uses automated production equipment. The company reports an annual production capacity of more than 10,000 units.
