1. Hardware configuration and working principle 

Single-channel ABS: Only the front wheels are equipped with the ABS system, which controls the front wheel braking through two oil pipes. The rear wheels do not have an independent anti-lock function. 

Its control logic usually adopts the axis control type (such as low selection control), with a relatively low cost (about 1,500 to 2,000 yuan). 

Dual-channel ABS: Both the front and rear wheels are equipped with independent ABS systems. Four oil pipes control the braking of the front and rear wheels respectively, and it is also equipped with a rear wheel sensor and a faster ECU computing speed. 

It adopts independent adjustment by wheel control, which can shorten the braking distance by 30% on slippery roads. 

2. Safety Performance Comparison 

Single-channel ABS: Mainly prevents the front wheel from locking up, suitable for daily riding, but rear wheel lockup may cause a fishtailing. 

Dual-channel ABS: Stabilizes both the front and rear wheels simultaneously, significantly reducing the risk of side skidding during braking in turns, enhancing safety by approximately 40%. 

3. Cost and Applicable Scenarios 

Single-channel: Low cost, mostly used in commuter models under 125cc. 

Dual-channel: Costing over 2,000 yuan, it requires professional matching and is commonly found in large-displacement or high-end vehicles. 

4. Technological Evolution Trends 

Dual-channel ABS is now being integrated with TCS (traction control), such as the 10th generation system from Bosch, which is smaller in size and has a faster response, becoming a standard feature in high-end models.
