Tern And EFBE Prüftechnik Collaborate On Cargo Bike Testing

Recently, urban mobility expert Tern announced that its GSD and HSD electric bicycles have passed the first, even exceeding the strict German new test standards for cargo bicycles.

Although cargo bicycles are popular in Europe and other regions, they have never been included in international safety standards before, such as the ISO 4210 standard for urban, hiking, youth, mountain and road bicycles, or the EN 15194 standard for electric bicycles. However, the situation is changing. The new German standard (DIN 79010: 2020-02 Bicycles-Transporters and Cargo Bikes) came into effect earlier this year, becoming the first standard to specify the test methods and safety requirements for electric and non-electric cargo bicycles . Both GSD and HSD have passed this standard and reached the required weight class.

Marcus Schröder, director of EFBE Prüftechnik and one of the main authors of the new German cargo bike standard, said: “We have seen many cargo bikes clearly failing more extensive tests. This is worrying.” “Having clarity The test standards are not only important to ensure that the rider feels at ease when carrying their children on the bicycle, but also to encourage manufacturers to follow basic safety requirements. We are very pleased to see companies such as Tern use laboratory testing to determine the design Weakness in

EFBE Tri-Test: Beyond the standard

The EFBE Tri-Test test is based on the German standard for cargo bicycle testing, but a proprietary maximum and overload test phase is added to the test sequence defined in DIN 79010 to verify that the product can withstand strange peak loads under maximum load. The edge is designed to use, which also ensures that even if the bicycle is beyond the limit, the bicycle can still remain safe and will not pose a threat to the safety of riders or passengers when overloaded.

The Tri-Test test contains 10 different frame stress tests. A single frame is required to pass all 10 tests, and any damage caused by one test will continue to the rest of the tests. Moreover, each test is carried out under a higher load, which will be proportionally higher according to the claimed bicycle weight and geometry. Some tests on the frame and front fork using Tern GSD show that its load is more than 300% higher than the load for city/hiking bicycles specified in the European EN 14764 standard. It is obvious that both GSD and HSD have passed the EFBE Tri-Test, reaching the load limits of 200 kg and 170 kg, respectively, which means that they meet and exceed the German freight bicycle standard.

Captain Josh Hong said: "The design of bicycles is changing rapidly. When you add passengers, cargo, and motors, the force increases rapidly. It is very important to develop safety and testing standards to cover these new bicycles. In many cases, There is no relevant test standard for the components we want to test. We are very happy to have EFBE as a partner that helps us design test standards to ensure the safety of our customers."
