The CHANGE MTB frame meets the highest standards of the European Committee for Standardization (CEN).
Unlike most folding bikes, the CHANGE frame is the ONLY folding design to achieve European Standard (EN) 14766 certified, which applies to Mountain frame, including folding frames.
This guarantees that cables will not be damaged when the frame is folded and also guarantees that the locking mechanism shall not loosen or unlock unintentionally during riding.
EN 14766 certification also involves the passing of the following tests, which were carried out by the esteemed Societe Generale de Surveillance (SGS):
|Test Clauses||EN 14766 Euro MTB||Test Method||Result|
|4.8.2||Frame and Front Fork Assembly-Impact Test (Falling Mass)||22.5kg Striker, Drop Height 360mm||Pass|
|4.8.3||Frame and Front-Fork Assembly-Impact Test (Falling Frame)||80kg Mass, 300mm Drop Height||Pass|
|4.8.4||Fatigue Test with Pedaling Forces||Downward Force 1,200N, 100,000 Test Cycles||Pass|
|4.8.5||Fatigue Test with Horizontal Forces||Force +1200N -600N, 50,000 Test Cycles||Pass|
|4.8.6||Fatigue Test with a Vertical Forces||Vertical Downward Force 1,200N, 50,000 Test Cycles||Pass|
|Test Clauses||EN 14781 Euro 700C||Test Method||Result|
|4.8.2||Frame and Front Fork Assembly-Impact Test (Falling Mass)||22.5kg Striker, Drop Height 212mm||Pass|
|4.8.3||Frame and Front-Fork Assembly-Impact Test (Falling Frame)||70kg Mass, 2 impacts||Pass|
|4.8.4||Fatigue Test with Pedaling Forces||Downward Force 1,100N, 100,000 Test Cycles||Pass|
|4.8.5||Fatigue Test with Horizontal Forces||Force +600N -600N, 100,000 Test Cycles||Pass|
The meeting of these exacting standards guarantees that the CHANGE is not only sturdy and stable for a folding frame, but also that riders can feel as safe using this frame as they would on any other mountain bike.
