The global electric bicycle market maintains explosive growth, and the matching performance of e-bike assist drivetrains directly determines riding smoothness and battery cruising range. Ordinary universal crank parts fail to adapt to electric motor torque output, causing severe power transmission loss and shortening e-bike mileage.
Jiankun focuses on R&D and mass production of professional e-bike and electric assist drive systems, including fully customizable electric crankset and chainring series. Our e-bike drivetrain components are structurally optimized for high motor torque characteristics: they perfectly match mid-drive and hub-drive motors of all mainstream power levels, cut power loss during transmission, and significantly extend single-charge cruising range.
We adopt anti-fatigue and high-temperature resistant alloy materials for all e-bike crank parts, adapting to long-hour continuous riding and complex bumpy road conditions. All products pass torque aging and high-low temperature durability tests to avoid crank arm cracking under long-term electric power load.
We offer diversified specification customization: adjustable crank lengths, multi-tooth chainring options and exclusive brand surface treatment. With mature mass production lines and strict finished product testing, Jiankun provides global e-bike manufacturers with high-stability, cost-effective full-set electric drive solutions, empowering new energy cycling product iteration and upgrading.
