In order to ensure that our electric bicycles can provide stable and safe performance in various riding environments, JOBOBIKE strictly implements and exceeds industry standards, especially demonstrating excellent strength in vertical force fatigue testing. This article will detail our fatigue testing process for applying vertical load to the seat tube and how it proves JOBOBIKE's commitment to quality.

1. What is vertical force fatigue testing?

Vertical force fatigue testing is designed to simulate the vertical load applied by the human body to the bicycle seat tube when riding. When riding, the rider's weight is transferred to the frame through the seat tube. This repetitive force may cause fatigue and damage to the frame. Therefore, the frame needs to undergo rigorous testing to ensure that it can maintain its strength and structural integrity over long periods of use.

2. EN15194-2017 Standard: Industry Benchmark

EN15194-2017 standard is the European safety standard for electric bicycles. It specifies the testing requirements for various components of electric bicycles, including fatigue testing of the frame. According to the EN15194-2017 standard, the frame needs to withstand a vertical load of 1100N for 50,000 cycles in the vertical force fatigue test. This standard provides minimum safety and durability requirements for electric bicycle manufacturers in the industry.

3. JOBOBIKE's custom test standards: higher requirements

In order to ensure that the product still maintains excellent performance in a more severe riding environment, JOBOBIKE sets more stringent test requirements than industry standards. We applied a load of 1200N in the vertical force fatigue test, which is much higher than the 1100N specified in EN15194-2017. At the same time, the number of test cycles has also increased from 50,000 to 100,000. This not only represents our confidence in product quality, but also our commitment to user safety and comfort experience.

4. Test process

Apply load: Through professional equipment, we applied a vertical force of 1200N at the seat tube position.

Number of tests: During the test, the frame needs to withstand 100,000 load cycles.

Observation and recording: During the entire test process, technicians monitor the stress of the frame in real time to ensure that the test is accurate and the data is reliable.

After rigorous testing, JOBOBIKE's frame performed well in 100,000 vertical force fatigue tests of 1200N without any obvious damage or performance degradation, proving its excellent durability in long-term riding.

5. Significance of the test results

Through this test that is more stringent than the industry standard, JOBOBIKE has demonstrated its commitment to quality. Higher applied loads and more cycles mean that our e-bikes not only perform well in daily use, but also maintain excellent durability under long-term riding and harsh road conditions. For riders, this means greater safety and longer service life.

6. Summary

JOBOBIKE has demonstrated our high attention to product quality and user experience with a frame vertical force fatigue test that far exceeds the industry standard. We are always committed to providing safer and more durable e-bikes, so that every user can enjoy peace of mind and comfort when riding. JOBOBIKE not only meets the standards, but also continues to break through in innovation and quality, striving to provide users with the best riding experience.

Through this test, we have proved that JOBOBIKE's frame has excellent fatigue resistance, which also provides our users with a more sturdy and reliable product choice.
