Leider macht der Controller was er will, die Unterstützungsstufen 1-4 zeigen keine Unterschiedliche Leistungsabgabe, diese sind alle auf ca. 80W geregelt. (ca. 2A) Ab Stufe 5 wird mehr Leistung abgegeben, bei Stufe 9 nimmt der Controller 15 A - sprich 600W bei einem vollen Akku. Zumindest das passt, daher 2 Sterne. Danach habe ich mit der Software die eingestellten Werte ausgelesen, die passen alle. Leider stimmen die gespeicherten Werte nicht mit den gemessenen Werten zusammen. Der Motor wird daher wieder ausgebaut und geht zurück. Mal sehen, wie lange es dauert, bis ich mein Geld zurück bekomme ## Features - Universal Compatible：BAFANG BBS01B BBS02B BBSHD Mid drive motor ebike conversion kit is compatible with mountain bike, road bike, commuter bike etc. Suitable for lower bottom brackets 68-73mm lengths and 34-36mm inner diameters, adhering to JIS norms. - Powerful motor: Mid drive motor BBS01B max torque up to 80 N.m.
