Rear Shock Absorber for Folding Bicycles — High-Strength Steel, Double-Layer Spring Key benefits and why you need it Durable steel construction: Made from high-quality steel for long service life and consistent performance under regular use. Better ride comfort and control: The double-layer spring design absorbs shocks and vibrations more effectively, reducing rider fatigue and improving handling. Reliable load capacity and strength: Two-layer springs provide improved load-bearing capability while the solid steel shaft serves as a robust axle with high tensile strength and resistance to breakage. Simple, safe design for varied conditions: A straightforward but secure structure is built to withstand different road surfaces, providing predictable behavior and easy control on rough patches. Main features Material: High-quality steel body and springs for durability and strength. Spring design: Double-layer spring for enhanced shock-absorbing performance and improved load distribution. Structure: Simple, secure rear-shock layout; the spring is the main shock body and the steel shaft functions as a strong, break-resistant axis. Function: Efficient shock damping that smooths out bumps and vibrations to increase stability and comfort on multiple surfaces. Application: Specifically designed as a rear shock absorber for foldable/folding bicycles. Performance and compatibility notes Designed to improve ride stability and comfort across typical urban and light off-road conditions. Suitable for foldable bicycle rear suspension systems that accept a steel-bodied shock with a double-layer spring design. Check your bike’s mounting dimensions and load requirements before purchase. Practical use scenarios Daily commuting: Smooths out potholes and rough city streets for a more comfortable ride during short or long commutes. Weekend rides and mixed surfaces: Improves control and reduces vibration on cobblestones, compact gravel paths, and uneven pavement. Carrying light loads: Helps maintain stability and comfort when riding with a rear rack or additional cargo common to foldable-bike commuting. This rear shock absorber focuses on robust materials and a functional, proven spring design to deliver reliable shock absorption and improved ride quality for folding bicycle riders.
