Traditional chain drivetrains have long plagued riders with annoying noise, greasy oil stains, frequent lubrication maintenance and fast wear. Today, low-noise, zero-maintenance belt drive systems have turned into a core selling point for high-end urban commuter bikes and leisure light e-bikes.
Shenzhen Jiankun independently developed a complete two-wheeler belt drive system, replacing metal chains with high-toughness industrial tensile belts and matched precision sprockets. Compared with chain drive, our belt drive system brings unmatched advantages:
Ultra-quiet riding: No metal friction noise during pedaling, ideal for quiet city commuting;
Zero oil pollution: No grease staining riders’ trousers or bike frames;
Extra-long service life: Strong tensile resistance, not easy to stretch or deform, service life 3–5 times longer than standard chains;
Low maintenance: No regular lubrication, chain cleaning or tension adjustment required.
Our modular belt drive kits include all matched crank, rear belt sprocket and connecting accessories needed for bike assembly. With strong compatibility, the system fits all types of city bikes, folding bikes and light electric bicycles. For bike brands planning to launch differentiated high-end commuter models, Jiankun’s complete belt drive solution can quickly upgrade product competitiveness and attract maintenance-averse urban riders. We support custom belt width, sprocket size and surface coating for brand exclusive customization.
